PART 1: ENGINE COMPANY OPERATION BASICS

he engine company is the basic unit of service in this Department and its tactics and operations should be familiar to all members. The purpose of this manual is to provide both general and specific information concerning engine company operations.

1. INTRODUCTION 1.1 This manual is based upon engine company staffing of an officer and four (4) firefighters.

In units staffed with five (5) firefighters the "door" and "control" functions are each performed by an individual firefighter. Engine company personnel should be familiar with both 4 and 5 firefighter operations since Department staffing varies on a citywide basis each tour.

1.2 Engine Company firefighters must be familiar with the apparatus currently in service with

the Department. Various makes and models exist and the differences between the apparatus include hose bed size and layout, location and number of discharge outlets, location and number of compartments, position of equipment such as ladders, large caliber streams, and hydrant connections.

1.3 When giving assignments, the Officer on duty shall ensure members are reminded of their

designations as safety team members. These members must be aware that this designation is based on their unit’s order of arrival at the box and will change as additional units arrive. While operating members shall pay particular attention to the following provisions:

T

The United States Department of Labor Occupational Safety and Health Administration’s (OSHA) revised standard regarding respiratory protection states:

1.3.1 Where an employer does not know or cannot reasonably estimate the concentration of contaminants in the work environment, it is assumed that the atmosphere is Immediately Dangerous to Life and Health (IDLH).

1.3.2 When a fire progresses past the incipient stage, the fire area must be considered and IDLH atmosphere. Every member entering the IDLH atmosphere must be equipped with personal protective equipment and a self-contained breathing apparatus. No member shall enter, leave or operate in an IDLH atmosphere unless the member teams-up with at least one other member and remains within visual or voice contact with that member. Each member of the search team shall know the company identity and assigned position of the other members of the search team. Handie-talkies or other electronic communication devices are not acceptable to replace visual or voice contact. At least one of the members of the team within the IDLH must have a handie-talkie and must be able to contact a handie-talkie- equipped member of the Safety Team outside of the IDLH atmosphere.

1.3.3 At least two members must team up prior to entering an IDLH (Two-In) and there must be at least two other members outside the IDLH (Two-Out), who are designated as a Safety Team. The members of the Safety Team shall be available to assist the interior team(s) if the need arises. If a member leaves a contaminated area, another member using an SCBA must accompany this member to a safe area.

1.3.4 If a confirmed life hazard is discovered and immediate action could prevent the loss of life, appropriate action (rescue activity) may be taken by an individual member. This applies only for a known life hazard, not for standard search and rescue activity. If such action is taken, the Incident Commander must be immediately notified and appropriate adjustments made. In all incidents of such individual action, the Incident Commander shall forward a report detailing the full particulars to the Chief of Operations. A thorough review of each of these incidents will be conducted.

2. IN QUARTERS

2.1 Planning and preparing for an engine company response begins the moment the fire

officer and firefighter enter quarters. The blackboard at the housewatch desk should be checked for any information that may affect the response or operations of the unit. Situations such as street closings, hydrants or mains out of service, standpipe or sprinkler systems inoperative, equipment changes on the apparatus or adjoining companies out of service should be noted and possible alternate courses of action considered and discussed.


3

2.2 Immediately after the start of each tour the officer shall conduct a roll call of the on duty

members and designate assignments. The following positions shall be assigned: nozzle, back-up, door, and control. For units staffed with four (4) firefighters, the “door” and “control” positions will be performed by the same member. Engine companies should also designate a member to perform forcible entry in the event that the assigned ladder company is delayed. When giving assignments, the Officer on duty shall ensure members are reminded of their designation as safety team members. (see Chap. 6, pg. 69) These members must be aware that this designation is based on their unit’s order of arrival at the box and may change as additional units arrive.

2.3 In addition to assigning firefighting positions, the officer will assign each member an

apparatus riding position, mask and handie-talkie radio. 2.4 Immediately after roll call, the company officer, accompanied by the chauffeur, should

inspect and examine the unit's apparatus. Any deficiencies noted shall be remedied or otherwise handled as per Department procedures and proper entries and notifications made by the officer. The following specific topics shall be discussed:

• General response routes and any modifications to normal response routes.

• Road and weather conditions.

• Dangerous areas or intersections.

The above listed topics are especially important for covering or detailed officers and chauffeurs.

2.5 Following the roll call, all engine company firefighters shall examine the apparatus hose

bed to familiarize themselves with the manner in which the hose is packed or folded. This is particularly important for detailed, overtime, or other than regularly assigned members.

2.6 Engine company firefighters shall stand roll call with all their Department issued personal

protective equipment. This equipment includes helmet, bunker coat, bunker pants and boots, gloves, and hood. In addition, a hose strap, chock, and spanner shall be carried by each engine company member. All members shall place their protective equipment at or near their respective riding position so that it can be donned prior to responding when necessary. The member on housewatch shall be guided by Regulations Chapter 20.

2.7 Department equipment such as Scott masks, handie-talkie radios, and PASS alarms shall

be assigned and inspected according to Department SOP's. Department issued flashlights should also be exchanged and inspected at this time and placed on the apparatus at each riding position. The location and presence of all tools and equipment on the apparatus shall be known by all assigned members and shall be verified at the start of each tour. The absence of a critical piece of equipment should be discovered during a routine apparatus inspection rather than at the scene of a fire or emergency.

2.8 The most important tools engine company firefighters use on the fireground are:

• Serviceable hydrants

• Engine apparatus

• Hose and fittings

• Nozzles

2.8.1 Hydrants - The importance of locating, connecting to, and operating a serviceable hydrant cannot be overemphasized. All engine company firefighters should be familiar with operating procedures for the several types of hydrants currently in use. In addition to different types of hydrants, there are several hydrant security devices which firefighters must be able to remove or activate.

2.8.2 Apparatus - In addition to transporting firefighters and equipment to the scene of a fire or emergency the engine company apparatus provides the water supply for fire attack. All engine company firefighters should be able to perform the following functions:

Transfer the engine apparatus from "road" to "pump".

Connect the apparatus to a hydrant using each of the several connections available and standard hose.

Charge and maintain adequate pressure on a hoseline using the pump panel controls.

2.8.3 Hose and fittings - Engine company firefighters must be familiar with the current hose inventory and methods of stretching. Fittings may be required to connect and adapt hose to other hose and hose to appliances. A well trained firefighter should be able to quickly locate and place into operation all hose/fitting combinations.

2.8.4 Nozzles - There are several different types and styles of nozzles in use in the Department and a knowledgeable engine company firefighter should be familiar with the specific applications and methods of use for each type. For example, the solid stream tip (MST) is useful for high volume flows with long reach, superior penetration and reduced nozzle reaction. It is required for standpipe operations due to its effective performance at low pressures. A fog tip is effective for ventilation, fires near energized electrical equipment and dispersing vapors at gas leaks. At the start of each tour, all nozzles carried on engine company apparatus should be inspected and examined to insure: (see Fig. 2-1 to 2-3)

What type of nozzles and/or tips are attached to each hoseline.

That rubber washers are placed correctly in female couplings and tips, and are not dried out or cracked.

That nozzles are hand fastened to hose and tips are screwed on by hand.

That fog nozzles are not clogged and are maintained in the straight stream position (tip rotated to the right).


5

That all control handles and shut-off valves operate freely and are maintained in the closed position.

2.9 Successful fireground operations do not happen by accident. For an engine company to perform well at fires and emergencies, its officers and members must be involved in an ongoing training program. The following Department activities must be conducted to ensure that a high

level of performance and professionalism is maintained:

2.9.1 Company drills - These are the most frequent drills conducted. The monthly drill schedule contains numerous engine related topics and there are several drill periods available each month for instruction in engine company operations. A wide range of experience and knowledge can be imparted to the members each tour by taking advantage of the varied backgrounds and firefighting experience of the company officer and senior firefighters on duty. This is the drill period when firefighters will be most receptive to instruction and will feel free to ask questions.

2.9.2 Multi-unit drills - This weekly drill period of 1 1/2 hours is an opportunity for several companies, both engine and ladder, to assemble and receive hands-on training. Engine company officers can use this period to review recent operations and walk through Evolutions with new members. Ladder company firefighters can also be instructed on engine company tactics.

2.9.3 Critiques of recent operations - Immediately upon return from a fire or emergency is the best time to conduct a critique or review of the operation. What each member of the company did and why they did it can be discussed and examined. The purpose of the critique is to provide a learning experience for all

3. RESPONSE CONSIDERATIONS 3.1 All responses to fires and emergencies should begin with proper receipt of the alarm. All

responding members should be informed as to the type of alarm the unit is responding to and the location or address. This information will determine whether or not protective clothing is necessary (CFR-D responses may not require complete donning of protective equipment) and will prepare members for the type of action or tactics that might be required, such as a hand stretch or the use of rolled-up lengths.

3.2 The only type of response that is helpful to the Department and the public is one that is

completed safely and accident free. Apparatus accidents can cause injuries to members and civilians and damage to the apparatus. Units unable to proceed to the alarm location are unable to render the assistance for which they were initially summoned. For these reasons a safe and reasonable response is necessary.

3.3 Engine companies returning from previous alarms or available on the air (10-8) must

consider the potential hazards caused by responding from locations outside of quarters. Other companies responding to the same incident may not expect to encounter this unit, which will be responding using other than its normal response route. This situation can cause surprise meetings at intersections and result in units arriving out of normal response sequence. It should be noted that the above situations can also occur when relocated companies respond from quarters (As always, units should be guided by their response assignments, i.e., 1st due, 2nd due, etc.). When two engine companies arrive at approximately the same time, but out of response sequence, they shall be guided by the alarm box assignment and operate in accordance with this Bulletin. For this reason, the second due engine company shall make no extraordinary effort to arrive first due, unless it is obvious the first due engine company will be seriously delayed.

3.4 Engine company members responding to an alarm should monitor the Department radio,

handie-talkie, and MDT screen. This will provide the officer and members with vital information about conditions at the scene and any problems encountered by earlier arriving units including water supply problems, trapped occupants, difficulties in locating the fire, heavy smoke conditions, or the need for special equipment.

3.5 Engine company firefighters should be prepared to conduct specific tactics for each of the

following types of responses:

3.5.1 Engine only - Since this is a single unit response, action to control situations in addition to engine work may be required such as forcible entry, victim removal, and search. All members must comply with the provisions of Sec. 1.3 of this Chapter).

3.5.2 First alarm response - Knowing if the unit is first or second due prepares the

company for certain procedures that may be employed upon arrival. If first due, the engine company can expect to initiate strategy and tactics according to the conditions found and to transmit the appropriate preliminary radio reports. If arriving second due, the engine company must ascertain if the first due engine


8

company has arrived and if not, assume their duties. If the first due engine has arrived, the second due engine company will augment and assist the first engine in whatever tactics have been initiated unless otherwise assigned by the Incident Commander (IC).

3.5.3 Multiple alarm response- When responding to multiple alarms, engine companies should anticipate long hose stretches, the need to supply large caliber streams, and to provide relief for first alarm engine companies.

3.6 Apparatus Positioning

♦ In order to avoid passing the fire building, if no specific address is given, engine companies should slow down upon approaching the box location. Look for any indicators that might identify the location of the fire or emergency or for persons attempting to gain the company’s attention. Be careful not to pass through an intersection where a turn into the block may be necessary. When a street address is provided, proceed directly to the location. House numbers generally follow a pattern, but be aware that some streets have house numbers on one side that do not relate to the numbers on the opposite side. Being familiar with the response area and any variations will assist in a unit’s response efficiency.

♦ The officer will decide where to position the apparatus once the fire location has been determined. This decision must be based on several factors, such as overall objectives, water source, type of fire, how close to the fire building the apparatus will be, the type of stretch to be made, and if the apparatus will block out or be blocked out by other incoming units.

♦ As per Department regulations, engine companies shall precede ladder companies when both units are responding together on the same alarm. This response sequence allows for several apparatus positioning options and does not hinder ladder company positioning.

♦ In order to facilitate an efficient and coordinated operation, the officer of the first engine company should strive to enter the block ahead of the first ladder company and from the same direction. This is particularly important where street width or parked cars would prevent the engine from passing the ladder apparatus to reach the desired hydrant. ( Fig. 3-1 ) This order of arrival allows the engine company firefighters to initiate a back stretch and accurately estimate, and remove enough hose by hand to reach the entrance of the fire building and adequately cover the anticipated fire area. After sufficient hose is removed, the engine company chauffeur (ECC) can proceed forward to the next hydrant and complete the remaining connections. This approach gives the members of the unit a view of up to three sides of the fire building prior to stretching a line. The engine company chauffeur (ECC) will be afforded a good view of street conditions and any approaching apparatus. This enables the ECC to contact via radio any company approaching from the opposite direction which might prevent the engine from reaching the desired hydrant.


9

Fig. 3-1 - The above illustration depicts an engine company stopping past the fire building to

perform a back stretch. After firefighters remove sufficient hose to reach the fire, engine apparatus back stretches, dropping hose as it proceeds to the hydrant. This allows the ladder company apparatus to take a tentative position upon arrival. With the exception of a fire building located at the end of a narrow dead end road, the ladder company should normally allow the engine company to enter the block first. This is to insure that both units don’t impede each others operation. Another exception to this procedure can be found in AUC 200 section 5.3.11, Winter Operations.

3.7 Engine Company Supply Guidelines 3.7.1 Establishing a positive water source is essential for a safe fire operation. Failure of a water source or pumper can lead to serious injury or death of FD members. It is essential that a positive water source be maintained. In order to provide a reliable and uninterrupted flow of water, all arriving engine and squad companies (assigned as an engine) shall locate and connect to a positive water source (hydrant, drafting, etc.). 3.7.2 Whenever possible, the following guidelines should be followed: Only two handlines should be operated from a pumper. The supply pumper in a relay operation should not supply any handlines or large caliber streams. The pumper supplying a large caliber stream should not supply any handlines or additional large caliber streams.

If an emergency requires exceeding the above guidelines, the supply or operating pumper shall be augmented as soon as possible to ensure that positive water is maintained and the Incident Commander shall be notified.

4. FIRE SCENE OPERATIONS 4.1 FIREFIGHTING OBJECTIVES

• PROTECTION OF LIFE o The protection of life is the primary consideration at any fireground operation.

Engine companies are often confronted with life saving operations upon arrival. Life saving operations are placed ahead of firefighting when sufficient firefighters are not available to do both, as is the case when no ladder company is on the scene. Judgment is a key factor when confronted with this situation. The best life saving measure may be a prompt attack on the fire which, if allowed to spread, would trap occupants. A life hazard, visible upon arrival, must be addressed.

o However, immediate rescue attempts by the first arriving engine company without simultaneously stretching and positioning a hoseline should be attempted only in extreme situations.

o Factors impacting on the decision to attempt an immediate rescue include:

The provisions of Sec. 1.3 of this Chapter are complied with. Occupants endangered by being in the immediate vicinity of the fire. Number of persons trapped. Occupants threatening to jump. Means of egress cutoff by fire. Ability to reach occupants with portable ladders. Anticipated arrival time of the first due ladder company. Staffing level of the engine company--four or five firefighters. Actions that the officer of the first arriving engine company can

implement to protect endangered occupants include:

• Position a hoseline between the fire and the endangered occupants.

• Ventilate to draw fire, heat, and smoke away from the endangered occupants.

• Give verbal instructions and assurances to the occupants.

• Close doors to limit the spread of smoke.

• Ensure that incoming units are informed of the location of endangered occupants.


11

• Depending on staffing, one member may be released from the stretch and proceed to the roof to provide vertical ventilation over the stairs. This action may reduce panic by relieving the smoke condition in the stairway. Proper tools must be brought to the roof and access to the roof of the fire building shall be made in accordance with established Department guidelines for the roof position.

• LOCATING THE FIRE

o Before any fire attack can be initiated, the exact location of the fire must be determined. This is the first stage of the fire suppression effort.

o Refer to response printout and/or department radio for reported particulars, i.e. floor or apartment number.

o Upon arrival, an exterior survey of the building should be conducted for visible flames, smoke, smoke blackened windows, occupants in distress, fire escapes being utilized by fleeing occupants, etc.

o Solicit information from occupants exiting via the interior stairs. o Listen to handie talkie radio traffic from ladder company personnel. o Often the odor given off by burning materials, even if there is no visible

smoke, may indicate what is burning and perhaps indicate where the fire might be located: ♦ Wood and paint odor - apartment. ♦ Food on the stove - apartment. ♦ Fuel oil odor - boiler room or basement. ♦ Rubbish odor - public hallway/stairway, compactor room, shafts. ♦ Electrical odor - overhead lights in hallways.

o While enroute to the reported fire location look out hallway windows or up stairwells for indications of fire or smoke.

o If a particular apartment is suspected to be the fire location, but the door is locked and there are no visible indications of a fire, try jostling the door. Smoke might puff out around the door casing.

o When the exact location of the fire has been determined it must be conveyed to the other units operating on the scene. The most direct route to the fire area must be relayed to the members stretching the initial hoseline.

• CONFINING/CONTROLLING THE FIRE

o Confining and controlling a fire is the second stage of the fire suppression effort and includes those actions taken to prevent the fire from extending beyond the area already involved. This is generally the immediate concern, and fulfills the role of placing a hoseline between the fire and the majority of the building occupants.


12

o Confinement of the fire must take into consideration the intensity of the fire as well as the known or anticipated direction of fire spread. Be aware that the fire may be extending via pipe recess, voids, concealed spaces, etc.

o Depending on the type of building and the fire location, the first line stretched and operated may be committed to confining any fire extension while a subsequent hoseline is utilized to extinguish the main body of fire.

o Example: Fire in the cellar of an Old Law Tenement (OLT), the first line is stretched into the first floor to protect the interior stairs and the second line is stretched into the cellar to extinguish the fire. (FFP-MD’s Sec 4.2.1)

o In some situations the closing of a door or window may play a vital role in confining the fire while hoselines are being stretched to the location.

o EXTINGUISHING THE FIRE

o Extinguishment is the third stage in the fire suppression effort. o Initial extinguishment includes “knock down” of visible flames and readily

apparent burning and smoldering material debris. Final extinguishment means that any fire uncovered by “opening up” and overhauling procedures has been extinguished.

4.2 STRATEGY AND TACTICS

4.2.1 The objectives of firefighting are to protect life and property by performing rescues, and by locating, confining and extinguishing fires.

4.2.2 Strategy and tactics defined:

STRATEGY - The general plan or course of action decided upon by the IC in order to achieve firefighting objectives.

TACTICS - The operations or actions required to carry out the strategy selected by the IC.

Most fire operations employ an offensive strategy which emphasizes the rapid stretching of hoselines for an aggressive interior attack on the seat of the fire. Engine company tactics at most structure fires are to stretch a hoseline via the primary means of egress (main entrance to the building), connect to a hydrant and attack the fire.

A defensive strategy may be employed, initially, at large or expanding fire operations where protection of exposures or containment of the fire is critical. Emphasis is placed on developing large water flows. Tactics compatible with these conditions might include positioning the apparatus for use of a LCS, such as the deck pipe, stretching a 2 1/2 inch hoseline for exposure protection or dropping 3 1/2 inch hose to supply an incoming Tower Ladder.


13

4.2.3 Selection and implementation of any strategic plan and its supporting tactics is dependent upon an accurate and ongoing size-up of the fire situation. Size-up starts with the receipt of the alarm and continues until the fire is under control. The size-up process may be carried out many times and by many different individuals during the course of a fire. The responsibility for size-up initially lies with the first officer on the scene, however all engine company members must make a personal size-up of the fire situation. As higher ranking officers arrive, the responsibility for size-up is passed up the chain of command.

An accurate and complete size-up must include consideration of the following strategic factors. They are:

A. Time of day G. Location/ extent of fire - sleeping occupants at night - cellar, sub cellars - rush hour traffic delays in response - cockloft - limited visibility at night - dumbwaiter

B. Life H. Water supply - residential vs. commercial building - hydrant spacing - occupied vs. vacant - hydrant serviceability - transient vs. permanent residents I. Street conditions - ambulatory vs. non-ambulatory - construction occupants

C. Area - elevated roadways - large volume of fire and railways - long stretches - overhead wires

D. Height J. Auxiliary appliances - elevator operations - standpipe systems

- standpipe stretches - sprinkler systems - long stretches K. Weather

E. Construction - wind direction and velocity - frame buildings - freezing conditions

- Truss roof and floor beams - heat stress - fire resistive L. Apparatus & Equipment - Old Law Tenements - large caliber streams

F. Occupancy - large diameter hose - Public Assembly - foam equipment

- Health Care Facility M. Exposures - Hazardous Materials - six sides of fire - Fuel Loading

5. ENGINE COMPANY PERSONNEL ASSIGNMENTS 5.1 ENGINE COMPANY OFFICER

5.1.1 After the engine company officer has determined that a hoseline is needed, the location, route, and number of lengths required in the stretch should be relayed to the unit's members. Properly trained firefighters should be able to perform the following tactics without the officer's personal supervision:

• Hose estimate and removal from the apparatus.

• Positioning the apparatus at a serviceable hydrant.

• Connection of the apparatus to a hydrant.

• Stretching a hoseline.

• Supplying booster water if ordered.

• Operation of apparatus mounted large caliber stream (LCS) device.

• Supplying standpipe and sprinkler systems.

5.1.2 The first arriving engine company officer should consider the removal and placement in the street of a second hoseline if fire conditions indicate it is warranted.

5.1.3 After ordering the first hoseline stretched, the engine officer should enter the fire building and begin gathering information that will assist the unit in stretching rapidly and accurately to the fire area. This information should include:

• Handie-talkie transmissions from the ladder company.

• Type of stairway present (i.e. return, straight run, around elevator).

• Presence or absence of a wellhole.

• Difficulties caused by large numbers of fleeing occupants.

5.1.4 If no ladder company is present, the Engine officer shall attempt to enter the

IDLH when teamed up with another available member. He/she may only enter individually to address a known life hazard as per Sec. 1.3 of this Chapter. If the ladder company is forcing the door to the fire area, the engine officer should proceed to the area immediately below the fire and:

• Determine the layout of the area (in multiple dwellings, layouts tend to be similar in each vertical line of apartments).

• Look at the ceiling for signs of structural weakness or holes.

• Look out a window to determine the location and extent of the fire on the fire floor.

• When returning to the fire floor, look out a stairway window in order to gain a different view of the fire floor from below.


16

5.1.5 While gathering information concerning the hoseline stretch, the engine officer should be alert to building occupants with information relative to persons trapped or distressed. If persons were reported trapped on the initial alarm, or if information or statements indicate this possibility, the engine officer should determine the following:

• Where are the people trapped?

• How many people are trapped?

• Are the trapped persons children or adults?

• Are the occupants normally home at his time of day?

5.1.6 While searching within a fire area, interior doors that can be used to help confine the fire until the arrival of the hoseline should be closed as soon as possible.

5.1.7 If the entrance door to the fire area (for example: this may be the apartment door in a multiple dwelling or a bedroom door in a private dwelling) is found open by the engine officer and entry is not possible, it should be closed immediately to prevent the products of combustion from entering the hallway and contaminating the upper floors and preventing the escape or removal of civilians from above the fire. Door control is critical to the safety of any firefighters operating on the floors above the fire.

5.1.8 Upon arrival of the nozzle team at the entrance to the fire area, the officer should assure that each fire fighter is properly equipped with bunker gear, helmet, gloves, mask and hood. After ascertaining that sufficient hose has been stretched and flaked out, the officer should call for water via handie-talkie and see that the line is properly bled of trapped air.

5.1.9 Prior to opening the door to the fire area for advancement of the line, the engine officer must assure that no firefighters will be exposed in the hallway or on the stairs above as the fire attack is initiated. This can be done via handie-talkie or in person. When the door to a fire area or fire apartment is opened, particularly in buildings equipped with thermal pane windows that have not self vented, there exists the possibility that fire will flash outward and upward and seriously expose or burn any firefighters operating in unprotected positions above the fire.

5.1.10 Immediately before moving into the fire area with the hoseline, the engine officer should relay to the nozzle team information gathered while the line was being stretched. This information might include phrases such as: “two rooms, left rear”, “straight down the hall, second room on left” or “holes in the floor, stay to your right hand wall”.

5.1.11 The nozzle team must begin every interior fire attack through the door to the fire area crouched low, near the floor, regardless of conditions. A sudden ceiling collapse, rapid self-venting or a fire driven by wind could create a blowtorch effect at the entrance door and seriously injure any firefighter in its path. After entry is made into the fire area, the engine officer can evaluate conditions and adjust or modify the method of advance used.


17

5.1.12 During the advance of the hoseline, the engine officer must constantly monitor the nozzle team's progress and the conditions around them. The protection afforded by bunker gear, masks, and hoods tends to insulate firefighters from the hostile fire environment which could cause members to penetrate unknowingly into severe conditions.

5.1.13 As the hoseline is advanced into the fire area, the engine officer should communicate orders and directions to the nozzle team using as few words as possible. The nozzle team should be advised of their progress and given estimates of how much fire remains to be extinguished.

5.1.14 Engine company officers should develop a communication system with the nozzle firefighter for use when voice communications are impaired due to stream impact noise, power saw operations, opening up and ventilation noise. The following system of touch signals can be used in conjunction with verbal commands to relay orders:

• Opening or closing the nozzle--One or two slaps on the back or shoulder.

• Direction of stream--Tug or pull on the arm or nozzle, either left or right.

• Advancement of hoseline--Steady push on back or mask cylinder.

• Halt or stop advance--Pull back on shoulder, bunker coat or mask assembly.

5.1.15 The engine company officer’s position while supervising the nozzle team must remain fluid. Due to conditions such as tight quarters, sock or furniture impediments, forays to vent or search and the nozzle team making turns and bends, the officer may have to drop back on the line, switch sides or even move ahead of the nozzle momentarily to allow for optimum nozzle positioning.

5.1.16 If an emergency situation develops which requires the immediate withdrawal of

the nozzle team, the officer or other member aware of the situation should indicate this fact by using four (4) strong slaps on the shoulder of the other members and then pull them in the direction of retreat.

5.1.17 After the main body of fire has been extinguished, the engine officer should order the nozzle shut down. This action allows heat and smoke to rise and vent and any remaining fire to "light up" and indicate those areas requiring follow up extinguishment. At this time the officer can check adjoining rooms or areas for fire extension.

5.1.18 When conditions permit, the engine officer may order a fog or broken stream directed out a window in the fire area to assist in removal of heat and smoke conditions. This action will also make search and overhaul operations easier. If the main stream tip (MST) was used to extinguish the fire, an effective broken stream can be produced for venting purposes by removing the tip and partially shutting down the control handle. The stream is directed out the selected window with the nozzle held 4-5 feet back from the window and the stream filling the


18

opening. If the FT-2 was used for extinguishment, the tip is adjusted so the a fog pattern fills the window opening and is operated similar to the MST.

5.1.19 The nozzle team is composed of the nozzle and back-up firefighters under the leadership of the officer. While some decision making authority is delegated to the nozzle firefighter, it must be understood that any actions taken are under the strict supervision of the officer in command of the line. The officer must exercise the power of command under fire attack conditions and expect prompt, implicit and unqualified response.

5.1.20 The following listed tactics are of such importance to fire control efforts that the decision to implement them is reserved for the engine officer alone.

• Calling for water (charging the line). • Opening the nozzle. • Initial stream direction ( at ceiling, seat of fire, etc. ) • Direction of team advance. • Initiating line advance. • Stopping line advance. • Stream shut down. • When adequate “knock down” has been achieved. • Use of stream for cooling. • Use of fog for attack. • Use of fog or broken stream for venting. • Amount of water used. • Assignment of engine firefighter for venting or search. • Relief of nozzle team. • Need for relief of the unit. • Necessity to back the hoseline out.

5.1.21 Decisions that may be delegated by the engine officer to the nozzle team include:

• Direction of stream. • Rate of advancement. • Opening nozzle in an emergency. • Partial shut down of the nozzle to reduce nozzle reaction and regain

control. • Calling for more line. • Sweeping floors with stream.

5.2 THE ENGINE COMPANY CHAUFFEUR (ECC)

5.2.1 The primary responsibility of the ECC is the safe delivery of the personnel, apparatus and equipment to a reported fire or emergency and the delivery of water to the operating firefighting force.

5.2.2 The ECC must monitor the handie-talkie for instructions and information that may require action and be ready to assist members in distress if ordered by the IC.

5.2.3 Engine company apparatus should be positioned as close as possible to the fire building to reduce the time, effort and number of lengths needed for the stretch. This tactic requires a coordinated effort between the ECC and the Engine Company officer and the first arriving ladder company for optimal placement.

5.2.4 ECC’s must recognize the need for and initiate supply line operations when required. When arriving other than first due, the ECC must remain aware of water supply needs of units already on the scene.

5.2.5 Tactics that ECC’s must be capable of performing include:

• Back stretch (Fig. 5-1)

• In-line pumping (ILP) (Fig. 5-2)

• Relaying water (Fig. 5-3)

• Drafting (Fig. 5-4)


20

5.2.6 The ECC should position the apparatus for a backstretch whenever possible. A hydrant in the immediate vicinity of the fire building may be used if it allows for a rapid stretch and will not interfere with ladder company positioning.

5.2.7 When performing a backstretch, even if an obstructed hydrant is encountered,

connection to such hydrants can usually be accomplished using a length of 3 ½ inch hose which must be carried and ready for this purpose or the 35 foot yellow hydrant connection.

Note: WHEN STRETCHING HOSE LINES OFF THE APPARATUS, THE APPARATUS SHOULD BE POSITIONED SO THAT IT WILL NOT INTERFERE WITH LADDER COMPANY POSITIONING.

5.3 THE NOZZLE POSITION

5.3.1 The firefighter assigned the nozzle occupies one of the most challenging and dangerous positions on the fireground. The duties associated with the nozzle position routinely take this firefighter in close proximity to the fire and require a determined and experienced member.

5.3.2 The nozzle is assigned by the officer at roll call along with the other engine company positions. The engine officer retains the flexibility to alter the assigned positions in order to allow a less experienced firefighter to work the nozzle at a minor fire where valuable “on the job” training can be gained.

5.3.3 The nozzle firefighter stretches the first length of hose with the nozzle attached via the route and to the location as ordered by the officer. This location should be a safe area in proximity of the fire area such as a stairway landing, hallway or adjoining area.

5.3.4 After flaking out the line in preparation for its advance, the nozzle firefighter should complete donning all required protective equipment including opening of the mask air cylinder and activation of the PASS device.

5.3.5 When the engine officer calls for water the nozzle firefighter must prepare to bleed the line of any trapped air. The nozzle can be cracked slightly open while the water is filling the line or it can be opened fully and closed quickly after water reaches the nozzle.

5.3.6 The nozzle firefighter should never enter the fire area without water. To do so could allow the fire to rapidly extend and overtake the nozzle team causing burns to them and any firefighters operating behind or above them.

5.3.7 When preparing to enter the fire area with a charged hoseline, the nozzle firefighter should ensure that if an adjustable fog/straight stream tip is being used, it is in the straight stream position (rotated to the right). If the solid stream tip is being used the 1/2 inch outer stream tip (OST) must be removed.

5.3.8 If the engine company is present on the fire floor prior to opening the door to the

fire area the firefighters assigned the nozzle and back-up positions, as well as the officer, should position themselves on the same side of the entrance and remain low. When the entrance door is opened the heat, smoke and toxic gases from the fire should be allowed to “blow.” As the smoke lifts, the nozzle firefighter may be able to look into the fire area at floor level and observe the room layout. Once the nozzle is opened, the thermal layers are disrupted and visibility is reduced significantly.

5.3.9 Once the nozzle team has water in the attack line and the door is opened, entrance is made into the fire occupancy. If the actual fire area is an interior room the nozzle firefighter must recognize this and advance as close as possible to the fire before opening the nozzle.


22

5.3.10 As a general rule, the nozzle should not be opened on smoke. If fire or high heat is encountered the nozzle can be used to cool and push the fire gases back toward the fire area by directing it upward toward the ceiling using a rapid side to side or clockwise motion.

5.3.11 After making the initial entrance into the fire area the nozzle team should move to either side of the doorway. This action is taken to remove these members from the flue like conditions that develop when the entrance door is opened. This condition becomes even more pronounced when the fire has not vented via windows and the entrance door is the first opening into the fire area.

5.3.12 While operating the line the firefighter assigned the nozzle position should hold the nozzle at arms length, out in front. This position allows the firefighter to redirect the nozzle quickly by simply bending the several feet of hose in the desired direction.

5.3.13 As the attack line is advanced into the fire area, the floor must be swept with the stream. This action cools hot plaster or burning debris and removes other potentially dangerous objects such as broken glass and drug paraphernalia from the path of the advancing firefighters. A change in the sound of the stream as it sweeps the floor could indicate the presence of an opening such as a hole, a stairway or an elevator shaft.

5.3.14 The manner in which a firefighter physically advances the hoseline may depend on the conditions encountered. There are several methods that can be used, each with their own advantages.

• Crawling - This method is useful where heat conditions require a very low approach to the fire area.

• Duck walking - This tactic is useful where rubble or debris which cannot be swept with the stream may cause injury or difficulty to the nozzle team. In housing projects or office buildings with concrete floors, duck walking keeps scalding water, a consequence of the fire attack, from absorbing into the bunker pants and burning firefighters knees.

• Leg forward (or outstretched leg) - This method can be used where the

integrity of the floor is in doubt. The outstretched leg is used to feel for holes in the floor before the full weight of the firefighter moves forward. Probing with the leg forward will also help the nozzle firefighter recognize the presence of descending stairs, ramps, or open shafts. This technique is recommended for commercial occupancies.


23

Fig. 5-5

5.3.15 The following nozzle handling techniques for directing the stream during fire attack are important for the nozzle firefighter to know and understand.

A. When operating the stream as the advance is made, the stream should be directed forward and upward, striking the ceiling and deflecting the stream toward the fire area (see Fig. 5-5).

The deflected water will:

• Cover a greater area.

• Break up and cool superheated combustible gases at ceiling level.

• Provide greater heat absorption by breaking up on impact and exposing more water surface area to the heat.

• Prevent “rollover” of the advancing fire. Prevent development of “flashover” by cooling the upper levels of the fire area.

B. Rapid side to side or clockwise rotation of the nozzle pushes the heat, fire

and steam ahead of the nozzle team.

C. As progress is made, the initial angle of the stream can be lowered and the stream can be directed toward the main body of fire.


24

D. Minimum steam generation at the lower level of the passage or hallway is desirable for rapid advance, therefore impacting side walls with streams should be minimized at lower levels. The steam generated initially at the upper levels will be pushed ahead with the heat and fire. Maintaining an adequate rate of flow will condense the steam and cool the fire gases ahead of the stream and will carry away the lower wall heat in the run-off.

E. The stream should not be operated directly overhead. This can cause hot water and debris to fall on the firefighters below. There are, however, several emergency situations which may justify this tactic:

• When the room “lights up” overhead.

• Fire rolls overhead or from behind.

F. When stock, furniture, partitions, vehicles, machinery or other obstructions block or prevent the stream from hitting the main body of fire, use the ceiling, walls or other stable, stationary objects to deflect water onto the fire.

G. Avoid knocking down stock with the stream whenever possible as it will conceal or extend fire and impede the hoseline advance. Fallen stock could also make it difficult for members to exit the fire area or back the hoseline out.

5.3.16 If rooms to either side of a hallway must be extinguished while advancing toward the main area of involvement, the stream should be operated well ahead of the line prior to turning to operate into the side rooms. This action is necessary in order to push back the advancing fire sufficiently to allow the nozzle team to safely reposition and operate into the side rooms.

5.3.17 A cardinal rule of engine operations is DON’T PASS FIRE. When advancing an attack hoseline through a fire area consisting of several rooms, it is usually only necessary to operate the stream from the doorway of each room/area. By utilizing the reach of the stream, the fire can be knocked down in these rooms and the hoseline can be advanced rapidly to extinguish the remaining areas. This tactic may leave smoldering debris or window frames but there should be no visible flame in the areas passed. (The term knock down means to have control of the fire area without complete extinguishment)

5.3.18 As the attack hoseline is advanced through the fire area all doors must be opened to assure that the nozzle team does not unknowingly pass an area involved in fire. Closed doors to closets, stairways and other rooms may contain hidden or extending fire which can burn through or erupt behind the nozzle team cutting off their escape route. Hoselines can also be burned through leaving the engine company without water and fire in front and behind them.

5.3.19 There are several situations which could result in the advance of the attack

hoseline being halted or slowed:

Situation #1 - Fire will not Darken Down or Cool Down


25

An engine company is making good progress advancing through a fire area and is suddenly stopped or slowed by fire that will not cool down or darken down.

Possible causes for this situation are:

• The stream is not adequately penetrating into the fire area.

• The stream may be inadequate for the size/intensity of the fire.

• A heavy body of fire may exist in another area which the stream is incapable of reaching.

Possible solutions:

• The stream direction may need to be adjusted to enter the room more completely or an advance of a few more feet may be necessary to open another avenue or direction of attack.

• The gallons per minute (GPM) flow may be insufficient due to friction loss, low pump pressure or kinks in the line. A handie-talkie message to “increase pressure” or “get the kinks” may result in an increased flow and faster knock down of the fire.

• If fire exists in an area which is incapable of being reached by this hoseline such as the floor below or an adjoining area, this attack line must make a stand at this point and hold the fire until a back up line can be stretched. The second hoseline can be stretched to the other area involved or can be advanced together with the first attack hoseline to press the attack into the fire.

Situation #2 - Fire has Darkened Down But Will Not Cool Down Possible causes for this situation are:

• The material and furnishings in the fire area have not been completely extinguished.

• Fire has extended into walls, floor and ceiling spaces and continues to burn there.

• Inadequate ventilation of the fire area.

Possible solutions:

• The areas where the fire was “knocked down” may need additional water application to completely extinguish all material, furnishings and structural components.

• Wall, floor and ceilings must be opened up to expose and extinguish any hidden fire.

• Initial or additional ventilation must be performed including the use of a fog or spray stream by the engine company.


26

5.3.20 FIRE ATTACK TECHNIQUES:

♦ Knowledge of the floor layout is the most valuable asset to a nozzle team advancing under heavy fire and/or smoke conditions. If the smoke is not banked down to the floor, a quick glance at floor level before opening the nozzle can give the nozzle firefighter and officer an indication of the floor layout. From this position, obstructions such as furniture, debris or other obstacles which could impede the advance of the nozzle team may be evident. The glow of the fire may indicate the direction and distance the team has to advance. Once the line is opened, any visibility will be lost until adequate ventilation is accomplished.

♦ The nozzle should be cracked open as the nozzle team waits for water.

The sound of exhausting air will indicate water is on the way, and any air in the line will be expelled. The line must be bled before the fire attack begins.

NEVER enter the fire area with an uncharged hoseline. However, the hoseline should be stretched as close to the fire area as possible before being charged. An uncharged hoseline is stretched more rapidly and it is less fatiguing than attempting to move a charged hoseline into position.

♦ All members should operate on the same side of the line. When the door

to the fire area is opened members should be low and to one side of the opening, to let the pent up heat and gases vent prior to advancing.

♦ Once the line is advancing, keep moving toward the seat of the fire. In order to reduce the chance of burn injuries and ensure rapid knockdown, the nozzle team should move aggressively but deliberately.

♦ Let the reach and penetrating power of the stream do the work, especially in large area buildings or when several rooms are involved in fire.

♦ The stream should be operated “out front and overhead”. The water should be deflected off the ceiling and upper walls. The nozzle firefighter should hold the nozzle at arms length to allow for maneuverability and change of nozzle direction (see Fig. 5-6).

• Fig. 5-6


27

♦ As the fire darkens down, the angle of the stream may be lowered to directly cool burning solid fuel material.

♦ Do not open the nozzle on smoke; try to get as close to the fire as safely

practical without risking burn injury.

♦ Do not crowd the nozzle.

♦ As the advance is made, listen for crackling of fire, look for a glow of fire

in the smoke, feel for heat.

♦ Listen to the sound of the stream as you sweep the nozzle across a room or area. The sound of the water striking a wall or partition will change if an opening such as a door or window is encountered. This opening might lead to a room or a hallway leading to another group of rooms where fire might still be burning.

♦ Once the fire appears to be knocked down consider shutting down the

nozzle to let the smoke and steam lift. Be prepared to reopen the nozzle at any moment.

♦ Even with the use of bunker gear, the floor should be swept with the

stream as you advance to cool any burning material and prevent knee and leg burns. This action will also sweep broken glass, hypodermic needles and other debris from the path of the advancing nozzle team.

♦ If it becomes necessary to withdraw an attack hoseline from a position due

to fire intensity, the stream must be kept in operation and the line should be backed out. Firefighters withdrawing a hoseline from an interior position should never turn their backs on the fire.

5.4 THE BACK-UP POSITION

5.4.1 The member assigned the back-up position is the second firefighter on the hoseline. This firefighter moves toward the fire behind the nozzle firefighter providing physical as well as moral support.

5.4.2 A major function of the back-up position is to flake out the hoseline while waiting for water and to facilitate the hoselines advance once it is charged.

5.4.3 Flaking out a hoseline can be accomplished using several methods depending on the conditions encountered. The following options can be used:

♦ The hose is flaked up the public hall stair above the fire floor. After the hoseline is charged the weight of the water in the line moving down the stairs will assist the firefighter assigned the door position feeding the line into the fire area (see Fig. 5-7).


28

♦ The hoseline is flaked out in the hallway on the fire floor. In buildings with large halls on each floor such as “H” type buildings and newer apartment houses, this option is effective (see Fig. 5-8).

♦ The hoseline is flaked out into an adjacent or opposite apartment on the fire floor. This tactic is useful when a small hallway is encountered and the hose cannot be laid up the stairs (see Fig. 5-9).

♦ The hoseline can be flaked out either wholly or partially in the public hallway on the floor immediately below the fire floor. This option is utilized when the volume or intensity of fire prevents access to the fire floor for flaking out the hoseline (see Fig. 5-10).

Fig 5.7 Fig 5.8

Fig 5.9 Fig 5.10


29

5.4.4 It is the back-up firefighters responsibility to absorb as much nozzle reaction as possible. By performing this function, the nozzle firefighter is able to advance and handle the nozzle without having to fight against the backward thrust of the operating stream.

5.4.5 In order to effectively operate, the back-up member must take a position as close as physically possible behind the nozzle firefighter. This arrangement allows the back-up member to exert forward thrust on the hoseline to counter the nozzle reaction.

5.4.6 The back-up firefighter must maintain a firm grip of the advancing hoseline at all times. If this member was to lose control of the line, the reaction of the opened nozzle could pull it through the grasp of the nozzle firefighter leaving the nozzle team unprotected from the fire . The unrestrained hoseline would also become a hazard until it was controlled or shut down.

5.4.7 When the nozzle firefighter wants to change the direction or elevation of the stream , the back-up member must maneuver the section of hose behind the nozzle firefighter in the opposite direction. The back up member must stay alert to the intentions of the nozzle firefighter and be able to quickly reposition behind that member.

5.4.8 During the initial hoseline advance, the back-up firefighter must maintain the hoseline below the level of the operating nozzle and keep the line as straight as possible.

5.5 THE DOOR POSITION

5.5.1 The third firefighter on the hoseline occupies the door position. This firefighter, like the nozzle and back-up firefighters removes approximately one length of hose from the hose bed. Following the back-up firefighter, the door firefighter carries the hose to a drop point, then lightens up on the line while proceeding to the fire area.

5.5.2 Upon arrival at the entrance to the fire area, the door firefighter assists with flaking out the hoseline in preparation for it being charged.

5.5.3 After the officer calls for and receives water at the nozzle, the nozzle team enters the fire area. At this point the firefighter at the door position slowly feeds line into the advancing nozzle team.

5.5.4 This member must not push the hoseline to the nozzle team, but instead provide enough slack in the line so that they can advance easily.

5.5.5 The door firefighter should maintain a bow or rise in the section of hoseline between the door and the nozzle team (see Fig. 5-10). This tactic will allow the door firefighter to monitor the advance of the nozzle team by observing the


30

straightening of the hoseline. As the hose straightens the member restores the bow in the line.

5.5.6 The door firefighter should conserve mask air, if conditions allow. If either member of the nozzle team requires relief or is injured, the door firefighter can quickly move into position and the attack on the fire can continue. The door firefighter should consider leaving the flashlight on which would serve as a guide for members exiting the fire area.

5.5.7 An important task of the door position is to monitor and observe heat, smoke and fire conditions at the entrance doorway. Undetected or extending fire could suddenly erupt or appear between the entrance and the nozzle team. The door firefighter is in a prime location to detect this situation and warn the nozzle team.

Fig. 5 - 10

5.6 THE CONTROL POSITION

5.6.1 The last firefighter on the hoseline occupies the most important control position. The control firefighter’s primary function is to assure that the correct amount of hose is stretched in order that the nozzle reaches the seat of the fire. It is necessary that this member have the experience and knowledge to correctly estimate the number of lengths of hose required for the type of stretch ordered by the officer.

5.6.2 This firefighter’s objective is to minimize the number of lengths stretched in order to reduce friction loss and kinks in the line. Excessive hose increases both friction loss and the potential for kinks which can cause a considerable reduction in both flow (gpm) and stream quality (compactness and reach) at the nozzle. Kinks also require higher engine pressures which increases the possibility of a burst length.

5.6.3 The success of an engine company hoseline operation relies greatly upon the actions of the control firefighter. The practice of assigning this important position to detailed ladder company firefighters or engine company firefighters who are unfamiliar with the units apparatus or building types, should be avoided. Where


31

possible, only the most experienced and knowledgeable firefighters should be assigned the control position. This will assure an accurate hose estimate and removal from the apparatus. A hoseline that is stretched quickly but in an uncontrolled fashion may result in excess hose and kinks or insufficient hose and a short stretch.

5.6.4 The control firefighter must develop good judgment in estimating the hose needed for various stretches by being familiar with the types of buildings in the units response area.

5.6.5 Factors that must be considered before a hoseline is stretched include:

• Distance from apparatus to building entrance.

• Distance from building entrance to foot of stairs.

• Type of stairs i.e. straight run, enclosed, return, around elevator, presence/absence of a well hole.

• Number of floors to ascend or descend.

• Distance to fire area from stairs/entrance.

• Size of fire area.

5.6.6 In order to keep track of the number of lengths of hose removed from a units hose bed by its members or others assisting in the stretch, the control firefighter must remain last in the stretch. Regardless of whether they are assisted by another unit or they perform the stretch alone, the control firefighter must complete the control function prior to initiating any other tactics. This is especially true when using the back stretch. In this situation the ECC is waiting for the hose to be removed prior to proceeding to a hydrant. If the control firefighter was to momentarily leave the back step area to assist in the stretch, the ECC will be delayed in proceeding to and connecting to a hydrant, which delays water to the nozzle. Another and more serious situation can occur if the ECC observes the control firefighter leaving the back step and assumes that enough hose has been removed. If the ECC proceeds to the hydrant and sufficient hose has not been removed a short stretch will result. Both of the above situations illustrate the critical importance of the control firefighter completing the hose estimate and removal prior to initiating other tactics.

5.6.7 When the second due engine arrives at the scene and a hoseline is being stretched, the first due control firefighter should not delegate or transfer the control position to the second due control firefighter. Instead, the first due control firefighter should maintain a position at the hose bed and complete the hose estimate and removal. The arrival of the second engine is not justification for the first due control firefighter to leave that position. Rather it eliminates the reason to leave, since there are now an additional 3 or 4 firefighters to assist with the stretch.

5.6.8 The control firefighter’s hose estimate function is considered complete when one of the following occurs:


32

A. The required number of lengths is removed from the hose bed, the line is broken, and connected to a pump discharge outlet. This scenario would occur when:

• A hydrant in close proximity to the fire building is used. In this case the control firefighter may assist the ECC with hydrant connection.

• ILP is used and the engine apparatus will remain near the front of the fire building.

B. The required number of lengths is removed from the hose bed and the control firefighter signals the ECC to proceed to a more distant hydrant (back stretch).

5.6.9 After completing the initial hose estimate, the control firefighter must perform the following additional tasks:

• Assist the ECC with the hydrant connection. This is done when the fire is located on a lower floor and the hydrant is in close proximity to the fire building.

• Feed slack toward firefighters ahead on the line. This includes pulling hose around parked cars, trees and building entrances where hose often gets pinched or couplings snagged.

• Flake out any hose between the apparatus and the building entrance door,

paying close attention to sharp bends or folds which may become kinks once the hoseline is charged.

• Check any doors that the dry hoseline is stretched through to assure that they are chocked open. If a door was to close over a dry hoseline that was subsequently charged, it would be extremely difficult to free the hose and may result in a drastic reduction in flow.

• Eliminate kinks in the charged hoseline while moving toward the fire area. This may require repositioning of hose in halls and stairways and straightening any bends that are restricting the water flow. It must be remembered that a single 90o kink in an 1 3/4 inch hoseline can result in a loss of 20 gpm or more. Successive kinks in a hoseline produces an accumulative affect on reducing flow and a hoseline with 3 kinks, for example, could lose 90 gpm or more, resulting in an ineffective and unsafe fire stream.


33

5.7 THE SECOND TO ARRIVE ENGINE COMPANY

5.7.1 In keeping with the Department’s goal of teaming engine companies to the greatest degree possible, the general duties of the second to arrive engine company are as follows:

• Assist with the stretching of the initial handline.

• Assure that the first due engine is connected to an adequate water supply.

• Relieve the first due engine company personnel as required.

5.7.2 The specific duties of the second arriving engine officer include:

• Water resource officer for the first hoseline.

• Provide a communications link between first due engine and IC.

• Control the number of members on the fire floor, limiting it to those necessary and directing others to appropriate staging areas below the fire floor.

• For reasons of safety, keep track of members going to the floor(s) above the fire. All members going to the floor(s) above the fire, before the fire is controlled, should communicate their identity to the second due engine officer before proceeding above.

5.7.3 The second arriving ECC shall:

• Position their apparatus at a hydrant and test it prior to assisting the first due ECC.

• Monitor the Department radio and answer for the Battalion or Division aide if either fails to respond to repeated calls from the dispatcher.

5.7.4 When Signal 10-70 is transmitted, the dispatcher will designate the second

arriving engine company as the “Water Resource Unit.” They must be prepared to initiate water supply operations compatible with conditions encountered at the scene. Their primary objective is to assist the first arriving engine to obtain a positive water source.

6. STRETCHING AND OPERATING HOSELINES 6.1 Stretching and operating hoselines is the primary function of an engine company. All

members must realize the importance of the initial line stretched at a structural fire. More lives are saved at fire operations by the proper positioning and operating of hoselines than by all other life saving techniques available to the firefighting forces. The majority of structural fires are controlled and extinguished by this initial line.


34

6.2 GUIDELINES FOR HOSELINE PLACEMENT

6.2.1 First Hoseline The first line is placed between the fire and any persons endangered by it. This is accomplished by stretching the hoseline via the primary means of egress, usually the main stairway. This tactic:

• Provides a base for confining and controlling the fire.

• Allows occupants to evacuate via the stairs.

• Allows members to proceed above the fire for search.

In most cases the first line is stretched via the interior stairs to the location of the fire. The purpose of this line is to protect the primary means of egress for occupants evacuating the building and to confine and extinguish the fire. An exception to stretching the first line up the interior stairs may be made when flame is issuing from windows opening onto the fire escape and endangering people trying to come down the fire escape. In this case the first line may be operated from the street to protect people on the fire escape. A second line should be promptly stretched into the interior of the building. If it is determined there is no life hazard in the building, the first line is positioned between the fire and the most severe exposure. The most severe exposure does not necessarily mean where the fire is likely to spread. Lines must be stretched to protect life first and in the absence of a life hazard, the first line should be placed to protect the greatest amount of property.

When placing a hoseline to protect an exterior exposure, it should be positioned so that the stream can be used alternately between operating on the exposure and the fire. When using streams to protect exposed buildings, the water should be applied onto the building’s surface for best results.

Example: Fire extending from cockloft of vacant row frame building, Exp. 4 is vacant and Exp. 2 is occupied. First line would probably be stretched to protect life hazard in occupied Exp. 2.

NOTE: The Engine Company officer shall announce via the handi-talkie when the initial

hoseline attack is to commence. Advancing hoselines will cause conditions opposite the hose line and above to worsen as the heat, fire, and steam are pushed in the direction by the force of the stream. Conditions in areas behind, adjoining or above the operating hoseline must be monitored for sudden possible deterioration due to the effects of hoseline advancement on the fire. All members must be alert to fireground communications concerning hoseline placement and the commencement of hoseline operations so that they may seek refuge if necessary.


35

6.2.2 Second Hoseline Unless otherwise ordered, the second line is placed to back up the first line. This tactic is used for the following reasons: • To provide a back-up to the first hoseline in case of a burst length in the

first hoseline. • To provide a second line to be used simultaneously with the first hoseline

if fire conditions warrant. • If the second line is not needed on the fire floor, it can be advanced to the

floor above. The second line stretched must consist of sufficient hose to cover the floor above.

6.2.3 Third Hoseline

Depending on the occupancy and the fire conditions, a third hoseline may be required. Unless otherwise ordered, this line may be stretched to:

• Cover a secondary means of egress. • Protect persons trapped on fire escapes above the fire. • Adjoining building to protect exposures or operate across shafts. • Prevent vertical extension.

See Fig 6-1 for hoseline placement guidelines.

Fig. 6-1


36

6.2.4 Other Hoseline Placement Guidelines

A. Difficulty might be encountered at some fire situations in conducting a direct attack through an apartment doorway due to a heavy volume of fire, wind conditions or forcible entry problems. A possible tactic to overcome these problems is to utilize the fire escape to conduct a fire attack into the apartment. BEFORE THIS IS INITIATED, members in the apartment must exit to a safe area of refuge and the apartment door must be closed in order to preserve the integrity of the hallway and interior stairs.

Another tactic is to enter an adjoining apartment and operate the hoseline through small holes in the common partition wall. Several small holes strategically located along the length of the common wall at approximately waist level might allow stream penetration into a majority of the rooms in the fire apartment.

B. Hoselines shall not be operated in opposition to each other. Hoselines operated in opposition to each other will push the heat, fire and steam toward the opposing nozzle team, creating dangerous operating conditions that can result in injuries to members on each nozzle team as well as to ladder company personnel.

C. Permission must be obtained by the IC before exterior hoselines are directed into a fire building.

D. Immediate notification must be given to the IC when a situation is discovered that requires the positioning of an additional hoseline.

E. When a hoseline is determined to be operating ineffectively, the IC must be notified.

6.3 In order to assure efficient and timely stretching of the first attack line, the services of the first two engine companies will be utilized. Whether staffed by 4 or 5 firefighters, the pairing of engine companies will in most cases result in a more rapid and efficient hoseline stretch and provides for continuity of the hoseline attack in the event emergency relief of the first engine is required.

6.4 Unless the presence of a confirmed life hazard requires the immediate stretching of a

second line, the second engine shall augment and assist the first engine. 6.5 Both engine companies shall retain unit cohesiveness. With the exception of the first due

control firefighter, second due engine firefighters, assisting in stretching the first line, should strive to maintain their position assignment on the line i.e. second due nozzle firefighter, backup firefighter, and control/door firefighter should follow the first due engine company.

6.6 The officers of the first and second due engine companies shall communicate with each

other and with the Incident Commander. 6.7 In one and two story structures, where the amount of hose required is four lengths or less,

the need to assist on the first hoseline is not as great and engine companies are generally capable of stretching and operating individually. In such cases, the officer of the second engine company should make contact with the officer of the first engine company to ascertain if their assistance is required.


37

6.8 Once the fire is located and the decision is made by the first arriving units to confine or extinguish the fire, orders must be given for the stretching of hose lines. The type of stretch, size of hose, and number of lengths will depend on many factors:

• Location and severity of fire. • Type of building or outside fire involved. • Source of water. • Type of hose loading on apparatus.

6.9 To minimize the number of lengths required and provide for rapid hoseline positioning, consideration must be given to the use of:

• Well-hole stretch. • Fire escape stretch. • Utility rope stretch via exterior of building. • Utility rope stretch via interior stair shaft windows. • In-line pumping. • Standpipe stretch with folded hose.

7. LOSS OF WATER ON THE FIRE GROUND The basic premise of the Engine Company operation is just that – Basic. We must stick to the basics of hose line placement to extinguish the fire. While stretching is in progress, there’ll be many variables to contend with; however having a good strong understanding of the basics will get us through a difficult stretch, or one in which there is a loss of water. Unfortunately, there will be times when we are challenged to a greater extent to position or maintain our hose line in operation. Three of these instances include:

♦ Kinks in the hose line ♦ Burst lengths ♦ Stretching short

These three situations will severely impact our operation. Each one will affect our water supply, and if not handled quickly and efficiently, can jeopardize the lives of both civilians and firefighters. These situations must be addressed. First we’ll discuss what we can do to prevent them from occurring; secondly, what needs to be done once a problem has arisen.

7.1 Water Loss - KINKS

The first area to cover is water loss due to kinks. This is also the easiest to correct. In fact, the proper stretching and positioning of the hose line will reduce the occurrence of kinks greatly.

♦ A single 90o kink in an 1¾ inch hoseline can result in a loss of 20gpm or more. Successive kinks in a hoseline produces an accumulative affect on reducing flow and a hoseline with 3 kinks, for example, could lose 90gpm or more, resulting in an ineffective and unsafe fire stream.

♦ All members should monitor handie-talkie communications. When an engine officer calls for additional pressure and the Engine Company Chauffeur (E.C.C.) responds that he is supplying sufficient pressure, this is a good indication that there are significant kinks in the line which must be corrected immediately.


38

♦ The control position is responsible for estimating the stretch accurately by limiting extra hose to 1 or 2 extra lengths. Effectively controlling the stretch will minimize kinks which can develop in the line.

♦ The control position is also responsible for flaking out hose before it’s

charged and checking the line for kinks once the line is charged. Start in the street and work your way up to where the door position is feeding hose into the fire area.

♦ All members stretching the hose line into position can reduce the number of

kinks that form by properly flaking out the hose.

♦ Any time the nozzle team advances and the line is fed from the hall into the apartment, there is a chance that a kink will form in the hallway.

♦ The control position, once on the fire floor, should help feed the line into the

fire area and continuously check the line insuring no new kinks have developed.

♦ When we know that we are dealing with kinks, the bottom line is to locate the

kink(s) and remove them. The way that you choose to remove the kink will be based upon the situation that you are in.

LEAVING KINKS IN THE LINE IS NOT AN OPTION!!!


39

7.2 Water Loss- BURST LENGTH

While having a kink in the line affects a hose line operation, it can usually be quickly located and corrected. This is not the case when we have a burst length. A burst length will severely affect the operation and can, depending on the situation, take a considerable amount of time to correct. There are many variables that will come into play when it comes to correcting the problem.

The optimal situation is to never have a burst length, but this is something that cannot be guaranteed. There a number of things that we can do to help prevent a burst length from occurring.

♦ The correct estimate of the stretch on the part of the control position will allow the ECC to maintain proper pump pressures. Excess hose calls for more pump pressure and a greater chance of bursting a length. While it is good to have extra hose so that we do not stretch short, we do not want to have excess hose in the stretch.

♦ Use the apparatus for as much of the stretching as possible. Hose stretched at

fires should be laid as close to the side of the street as possible and on the same side as the hydrant or pumper. If it is necessary for hoselines to cross the street, the lines should cross in front of the fire building. This allows as much room as possible for the maneuvering of apparatus.

♦ Extra hose on the sidewalk must be kept away from the front of the building

where ladders are being placed and falling glass may puncture it.

♦ During the stretch, care should be taken when going under and around rusted and jagged doorframes and newel posts, broken glass in the hallways, construction debris with exposed nails, etc.

♦ Caution should be taken where skylights are present. Falling glass from

vented skylights can puncture and burst hose lines. Therefore, do not flake out hose directly under any skylight when possible.

WATER LOSS “URGENT!!!” BURST LENGTH


40

♦ When operating in the fire apartment, recognize areas of burning embers and

hot debris. Members shall prevent the hose from being damaged by burning material.

♦ Things that need to be considered:

A burst length constitutes a “Water Loss” and when recognized by any

member, should be transmitted as an “Urgent” message on the radio. Communication at this time is extremely important. This fact should be communicated to the Incident Commander (I.C.) immediately. The I.C. is the highest-ranking officer at the scene.

Once a burst length is confirmed, the engine officer must initiate

action to correct the problem. This may include using the second engine officer (water resource officer) and members in coordinating the effort to solve the problem.

The unit with the burst length should back out of the fire area and seek

an area of refuge.

All units operating on the floor or floors above should be notified immediately to either back down to the floor below the fire or seek an area of refuge.

If a hose line is in place on the floor above, it will have to be called

down to cover the main body of fire.

At any working fire it may be decided to put another uncharged hose line to the front of the fire building to be used if any of the lines operating should have a problem.

All engine companies should consider carrying an extra length of 1 ¾

and 2 ½ hose (with proper size nozzle attached) similar to standpipe fold/roll ups that can be easily accessed and brought into the building to replace a burst length.

♦ Correcting a Burst Length: To determine how to best correct a burst length, first we must decide where the burst length is located in the stretch. Once determined where it’s located, we must decide if we are dealing with a long

stretch or a short stretch. Any stretch that is four lengths or less is considered a short stretch; all others are considered long stretches.


41

Burst Length in Lead or Nozzle Length (Two Options)

o Long Stretch (five or more lengths) Shut down the line at the pumps. Remove nozzle, then remove the lead length of hose from stretch. Insert a new lead length from the apparatus and reattach the nozzle. When complete, notify the ECC to re-charge the line.

o Short Stretch (4 lengths or less)

Shut down the line at the pumps. The nozzle is removed from the lead length. Lead length is removed from the stretch. Nozzle is reattached to the second length and a new length can be added at the pump panel by ECC. Once the hose butts are attached and confirmed as such, the line can be recharged and advanced back into position.

NOTE – Option #2 is only to be used when you are dealing with a short stretch.

Burst Length in the Middle of the Stretch (Two Options):

o Eliminate one length- If the stretch is long enough and it’s possible to eliminate one length, shut down the line at the pumps. Disconnect the butts of the burst length, eliminate it from the stretch, then pull the butts of the adjoining lengths together and reconnect the butts. Call for water to recharge the line when complete.

o Replace the Burst Length- Shut down the line at the pumps. Have members bring in an extra length of (Rolled/Folded) hose from the apparatus. While waiting for the new hose, the members in hall shall disconnect the damaged length of hose and when the new length arrives, insert it into the stretch. Call for water to recharge the line when complete.

NOTE – Both of these options are available for either the long or the short stretch.

Burst Length in the Street: Manpower in the street should be able to shut down the pumps, replace the damaged length , recharge the line and not have to withdraw any of the members from inside the fire building to assist.


42

7.3 Stretching Short

Accurately estimating the length of the stretch is the responsibility of the control position. It is a job that must be done correctly because if there is not enough hose in the stretch then the nozzle team will not be able to reach their objective. If there is too much hose in the stretch then we must increase the pump pressures and risk bursting a length of hose as well as create more kinks in the line and make it less manageable. They key is to have some extra hose but not an excess of hose.

Estimating the Stretch o Distance from apparatus to building entrance. o Distance from building entrance to foot of stairs. o Type of stairs i.e. straight run, enclosed, return, around

elevator, presence/absence of a well hole. o Number of floors to ascend or descend. o Distance to fire area from stairs/entrance. o Size of fire area.

What we can do to help estimate the stretch: o Knowledge of building construction. Knowing the

differences in sizes and layouts between building types, i.e., New Law Tenement (N.L.T.) or Old Law Tenement (O.L.T.)

o Knowledge of the buildings in the district. When on AFID or EMS runs, note any remarkable features affecting our Standard Operating Procedures (S.O.P.).

o Knowledge of different types of stairways. Do they wrap around an elevator core? Are they return style with a well hole? This information will affect the number of lengths required in the stretch.

o Knowledge of how much hose is on the apparatus. You need to know this in case you are distracted during the stretch. You will know how much hose is off the rig based upon how much is left on the rig.

o Remember the ECC needs to know the number of lengths so that they may set the pump pressures accordingly.

How to correct a stretching short situation:

o 1 ¾ or 2 ½ hose –Short Stretch (four or less lengths) First shut down. Then add a length of hose at the pump panel. Recharge line. Continue advance.

o 1 ¾ with a long stretch (5 lengths or more) or already

charged:


43

A length of 1 ¾ hose with a nozzle attached is brought to the front of the line. The tip is removed from the original nozzle and the extra length is added by connecting the female butt to the shut off. In order to charge the new lead length, we must open the shut-off from the original nozzle which will now be acting as an in-line gate. When a shut off is being used as an in-line gate great care must be taken as it must be monitored so that it does not accidentally get shut down. This option, adding a length to a charged hose line, allows us to keep the line in operation without shutting down at the pumps.

o 2 ½ with a long stretch (5 lengths or more) or already

charged: Shut down the line at the pump panel only after the additional lengths of hose have been brought to the front of the line. The nozzle is removed from the lead length of hose and the additional length(s) are added on. Place this nozzle onto the new lead length of hose and call the ECC to recharge the line.


44

7.4 Conclusion

The loss of water on the fire ground is a very serious situation, and it is something we must strive to prevent. Even with our best efforts there will be times when these situations arise and we must be prepared to deal with them. We must remember that any time we have a loss of water, both civilians and firefighters are at great risk. Communication at this time to all members operating at the incident is extremely important. It will be through our knowledge, training and professionalism that we will reduce these problems and when it does happen we will handle it quickly and efficiently, without compromising the operation.

1. ESTIMATING A HOSE STRETCH 1.1 When the orders are given to stretch a handline, a rapid estimation of the number

of lengths required to reach the seat of the fire is in order. The general rule for estimating the number of lengths in the fire building is:

1 length per floor + 1 length for the fire floor. Ex. 5 story NLT, fire on the 4th floor would require 5 lengths (4+1=5).

1.2 This rule assumes that the engine has stopped at the fire building and the required

lengths are removed prior to repositioning the apparatus at a hydrant. 1.3 For large multiple dwellings (H-types and their variations), hose estimations must

consider the distance from the backstep of the engine to the entrance door. In some cases several lengths of hose might be required to reach the entrance door. The distance from the entrance door to the base of the stairway must also be considered. This is in addition to the required one length per floor plus one for the fire floor. Some buildings may require two lengths for the fire floor.

1.4 If the engine apparatus is positioned at a hydrant before reaching the fire building or has to pass the fire building, the additional distance must be taken into account in estimating the number of lengths required to reach the seat of the fire. The building frontage can be used to estimate the required number of additional lengths. Ex: row of OLT's, engine is two buildings past fire building, OLT 20-25' wide, at least 2 lengths will be needed to reach the entrance to the fire building.

1.5 Use the apparatus for as much of the stretching as possible. Hose stretched at

fires should be laid as close to the side of the street as possible and on the same side as the hydrant or pumper. If it is necessary for hoselines to cross the street, the lines should cross in front of the fire building. This allows as much room as possible for the maneuvering of apparatus.


48

2. WELL-HOLE STRETCH

2.1 The use of a well-hole for stretching the hoseline allows for more rapid positioning of the line and reduces the number of lengths required. The rule of thumb is that a 5 story stretch up a well-hole requires about one length of hose (see Fig. 2-1A & 2-1B).

2.2 The engine officer should communicate to the members stretching, the presence

of a well-hole, as soon as possible. The officer should look up the well to see if it goes up the entire stairway. In certain stair configurations, a well exists between the 1st and 2nd floor, but the rest of the stairway does not have sufficient space to accept a charged hoseline.

2.3 The stretch is accomplished as follows:

A. The nozzle firefighter has two options depending on the size and configuration of the well-hole.

• Narrow well-hole - nozzle firefighter drops his/her folds at the base of stairway, securely grasps the nozzle and proceeds up stairway pulling hose up through well-hole.

• Wide well-hole - nozzle firefighter carries nozzle and lead length in well.

B. If conditions on the fire floor are favorable,

and the door to the fire area is controlled, sufficient hose must be pulled up and flaked out on the fire floor.

C. If the fire has extended into public hallway,

sufficient line must be pulled up and flaked out on the floor below.

D. When sufficient line has been pulled up the

well-hole, the line must be secured with a hose strap.

E. The backup firefighter initially feeds line to the

nozzle firefighter from the base of the stairway, then proceeds up the stairway pulling line up the well-hole.

Fig. 2-1A


49

F. The door firefighter lightens up on the line and proceeds up the stairway

pulling line up the well-hole.

G. The control firefighter will remain at the base of the stairway until notified by the officer that sufficient hose has been stretched. Any remaining hose on the first floor should be flaked out and checked for kinks, once the line is charged.

2.4 When a second hoseline is stretched up a well-hole, caution must be exercised to ensure the first and second lines do not become entangled. To prevent entanglement, the nozzle firefighter should carry only the nozzle and change hands at each newel post (turn) as the line is stretched up the well-hole. A utility rope can also be used if the well-hole is large enough to accommodate its use.

Fig. 2-1B

WELL - HOLE STRETCH Fire on fifth floor TOTAL = 3 LENGTHS

3. FIRE ESCAPE STRETCH The fire escape stretch can be utilized to stretch a hoseline (or an additional line) via the

outside of the building. The line can be stretched to the balcony of the floor below the fire and in through a window and up to the fire floor via the interior stairs. Another option, when there is no access via the interior (i.e. a vacant with damaged interior stairs) is to stretch up to the balcony of the floor below the fire and then gain access to the fire area via the balcony through a window on the fire floor.

NOTE: The following is the procedure to follow when utilizing the fire escape to

access the fire floor from the fire escape.

3.1 Sufficient hose should be stretched and arranged below the fire escape balcony. 3.2 The hose can be hoisted with a utility rope or a 6 foot hook.

♦ If the rope is used: the nozzle firefighter should proceed directly to the balcony of the floor below the fire and pull up the nozzle once the Control firefighter secures it to the rope.

♦ If a 6 foot hook is used: members ascend the fire escape and position themselves on successive balconies, with the nozzle firefighter proceeding to the upper balcony. At ground level, the control firefighter inverts the hook and places the handle of the controlling nozzle onto the hook. The handle is passed from the member below to the member on the balcony above. The member on the lowest balcony (door Firefighter) remains at this position to lighten up on the hose until sufficient hose is hoisted. Nozzle and back-up firefighters continually pass the hook up and move up until the nozzle reaches the balcony of the floor below the fire. In both cases the control firefighter will remain at ground level and assist in hoisting and securing the line. Once sufficient line has been hoisted and the line has been charged, the control firefighter can ascend the fire escape and join the nozzle team (see Fig. 3-1).

3.3 Once the nozzle reaches the balcony of the floor below the fire, the nozzleman

must secure the nozzle and notify other members to move up one landing (exception: Control firefighter remains at ground level). At this point the nozzleman pulls up sufficient hose to make entry on the fire floor above. This additional hose can be flaked over the fire escape railing. Once this hose is in place the nozzleman can position himself roughly half way up the steps to the fire floor landing to await water.

3.4 The back-up man, upon reaching the balcony below the fire will pull additional

hose to operate through the fire area above. When sufficient hose is pulled onto this balcony the back-up man will secure the line with a hose strap and then join the nozzleman.


51

3.5 The doorman, will initially lighten up on the hoseline as it’s being hoisted. Once the backup man is done hoisting hose the doorman (if necessary) will secure the hose to the fire escape railing and then proceed up to flake out hose from the fire escape into a window on the floor below the fire.

3.3 The line must be secured with hose straps on alternate floors, beginning with the

floor below the fire.

Fig. 3.1

3.4 NOTES: ♦ The line is secured with hose straps beginning with the floor below the fire

and continuing with alternate floors down. ♦ Hose straps are used as follows: hook end of strap is passed around hose and

through loop of rope. It’s then pulled taught, brought over and under fire escape railing, and then hooked on strap.

♦ Prior to charging the line members must position themselves between the dry line and the building- not the dry line and the fire escape railing.

♦ Fire below the 4th floor, the line is stretched up the well of the fire escape.


52

4. UTILITY ROPE STRETCH

4.1 Engine companies should carry 75 feet of 3/8 inch nylon rope to be used for a quick, efficient stretch to upper floors or roofs (see Fig. 4-1). This rope can be used to haul the line:

• To roofs of low buildings, i.e., taxpayers, three story frames, brownstones.

• In vacant buildings when interior stairs are missing or damaged and would present a hazard in supporting an interior stretch.

• In buildings with the staircase winding around an elevator shaft.

• At fires requiring three lines, when the interior stairs already have two lines on them.

• When CIDS or previous knowledge indicates its use.

• In non-standpipe project buildings.

Fig. 4-1

4.2 Example: Utility Rope Stretch Via Stair Shaft Window In Buildings With Stairs

That Wrap Around An Elevator.

♦ In order to reduce the number of lengths required and speed up the stretch,

the line can be hoisted via stair shaft window with the utility rope. If the fire is below the third floor, the line is stretched up the stairs.


53

♦ The officer's initial size-up will determine if this type of stretch would be beneficial in reducing the number of lengths required. Knowledge of the building, the location of the fire, and availability of stair shaft windows will assist in making this determination.

♦ The line is stretched as follows:

• The officer proceeds to the floor below the fire with the rope, selects the window to be used, and communicates this information to the control firefighter. The rope is deployed from this window.

• Sufficient lengths must be brought into the lobby and the folds arranged near the window selected by the officer. The nozzle firefighter attaches the rope to the nozzle, places the nozzle outside the window, then proceeds to the floor below the fire.

• The backup firefighter will join the nozzle firefighter when relieved by the control firefighter. The control firefighter must remain at the window until enough line is hoisted to ensure that the line does not get hung up. Once the line is charged, the control firefighter will check for kinks and join the nozzle team.

4.3 OPERATIONAL CONSIDERATIONS USING UTILITY ROPE

♦ Before the utility rope is deployed, look out the window and check for

obstacles or obstructions such as air conditioners, clotheslines, overhangs or setbacks which might interfere with the rope.

♦ Remove the child guard if present, raise the lower sash and ensure that it stays open.

♦ At the lower floor window, lower the top sash, grab rope and tie to nozzle.

♦ Members must be aware that tools will be required to remove child guards. Some windows will be secured closed and others may have stops which limit the raising of the sash only a few inches.

♦ Hinged windows which open outward can prove difficult and similar windows on intermediate floors may have to be closed to prevent the line from getting hung up.

♦ If difficulty is encountered in raising a window, remove glass from sash.


54

5. BACK STRETCH:

A backstretch is a stretch of an attack line in which the pumper reaches the fire before the hydrant. The necessary amount of hose to reach the fire is removed and the pumper can be used to fill out the stretch. As the pumper proceeds to a hydrant the additional necessary hose peels off the rear of the hosebed.

5.1. Steps:

♦ Pumper stops in vicinity of fire building so as not to impede the positioning of a truck company. (In most cases the engine will stop the proper distance beyond the building entrance, taking into account the type of ladder apparatus responding in, directly from behind). Firefighters remove enough hose to reach fire. (See Fig 5-1). Use side of hoseload that ends with male coupling. Attach nozzle to line and advance to point of operation.

♦ Pumper proceeds to hydrant playing out hose on way. One member (control

firefighter) rides rear step, standing clear of moving hose. Upon reaching hydrant, connect pumper; break hose line and attach to pumper. Officer gives command, "Start Water." Control firefighter after controlling stretch, proceeds to fire, moving hose close to curb, removing kinks etc.(See Fig 5-2)

Fig 5-1

Fig 5-2


55

5.2 Removing Hose From Apparatus

♦ To Remove hose from apparatus one member mounts rear step of apparatus, places arm through first 3 folds of hose, gives a strong pull, steps down and walks backward, dragging hose. Firefighter lays hose on ground about 15 feet from apparatus and slightly to side in direction of stretch. A second firefighter lays the next three folds directly to rear of apparatus. A third member lays the next three folds slightly to side away from direction of stretch. There are now three full lengths laid out neatly in street. Additional hose may be removed similarly.

♦ Advancing line to fire -- (Three members used). Attach nozzle to line. Each

firefighter carries three folds of hose. They walk toward point of operation with loop of hose between each member. As they advance, hose is played out in a continuous line beginning with last firefighter.

♦ When fire and hydrant are adjacent, apparatus need not be used in stretching lines.

♦ If, on rolling in to fire, the officer anticipates use of multiple lines, two lines shall

be laid simultaneously by apparatus performing stretch. 6. INLINE PUMPING:

Inline pumping is a stretch of the supply line in which the hydrant is located before the fire (in relation to the direction of the pumper’s response). In this evolution the supply line can be stretched from the hydrant to the pumper’s operating point (in this situation the hose would peel off the hosebed as the pumper proceeded to the operating point). Another option would be to hand stretch the supply line from the operating point back to the hydrant.

Note: 4 FF Engine Co. 5 FF Engine Co.

Hydrant FF = Control FF Hydrant FF = Control FF

Hose FF = Back-up FF Hose FF = Door FF 6.1 Steps:

♦ Pumper stops so that the rear step is opposite the hydrant. The Hydrant FF equipped with a hydrant wrench and a 2½” gate, tests the hydrant. A bolt cutter should be taken if necessary.

♦ After the hydrant is deemed serviceable, the Hose FF keys the hydrant by

pulling sufficient 3½” hose from the hose bed prepared for In-Line Pumping (ILP) and takes a turn around the hydrant. (See Figure 1) The Hose FF then mounts the pumper's backstep, and prepares to use the signal buzzer. (See Note 10)


56

♦ The Hydrant FF should: 1. Maintain the key as the pumper proceeds. (See Figure 2) 2. Connect the 3½” hose to the 4½” outlet of the hydrant.

(See Figure 3) 3. If time permits, connect a 2½” gate to the hydrants 2½” outlet.

(See Figure 3) 4. Waits for notification from the ECC before opening the hydrant.

(See Figure 4)

6.2 At a slow rate of speed, playing out 3½” hose, the pumper proceeds to the vicinity of the fire building, so as not to impede the positioning of a ladder company.The Hose FF rides the rear step and monitors the playing out of the supply hose.

6.3 Pumper stops at the operating position where the members remove enough hose to

reach the fire. The ECC: 1) “Drops” booster tank water into pumps 2) Engages the pump

3) Breaks the 3½” inch supply line and connects it to the 3” gated inlet on the pump panel side.

4) Notifies the Hydrant FF to start water. Note: The ECC should leave the gated inlet closed while opening the drain to the gated inlet, thus allowing air in the 3½” supply line to exhaust. When good water flow is observed flowing through the drain, the ECC should close the drain. The ECC should then slowly open the 3” inlet gate fully, then prime the pumps and begin fire line operations as per standard operating procedures. Supplying booster water upon Officer's orders shall be given priority over hooking up the in-line supply line. 6.4 After receiving notification from the ECC to start water, the Hydrant FF opens the

hydrant fully and then proceeds to the pumper for the purpose of controlling the stretch. The Hydrant FF, after controlling the stretch, ensures tools are placed on the apparatus and then proceeds to the fire, moving hose close to the curb, removing kinks, etc.

Note: Depending on staffing, the initial handline stretch will be controlled by either the Door FF (5 FF Engine) or the ECC (4 FF Engine), until relieved by the Control FF (Hydrant Firefighter).

6.5 When the Engine Officer calls for water, the ECC supplies available water,

notifying the officer as to type. If booster water is used, the ECC must notify the Engine Officer when hydrant water is started.

6.8 ECC notifies the Incident Commander and incoming Engine Companies when the

necessity exists for the ILP pumper to be augmented. (See Note 5)

NOTES: 1. Hydrant shall be tested and flushed before the supply line is committed. 2. Hydrant selected for ILP must be on a 6” or larger main. During Water Alert, ILP shall

not be used unless absolutely necessary. 3. Pumper shall use 3½” inch hose as the initial supply line from the hydrant to the pumper. 4. Not more than 6 lengths of hose shall be used in the initial supply line. 5. When intake pressure drops below 15 psi, the pump operator shall have his intake supply

augmented. 6. Necessary fittings to connect to a hydrant shall be preconnected to the 3½” supply hose

on the pumper. 7. In order to prevent injuries or damage to hose or equipment, the supply line shall not be

preconnected to an inlet of the pumper.


58

8. Consideration should be given to the pumper mounted deck pipe nozzle in ILP positioning when the need for exposure protection or quick knock down is evident.

9. Pumpers should not be positioned where they will prevent effective utilization of aerial and tower ladders.

10. Pumper may proceed to the operating position, stopping only to drop the Hydrant FF off

for testing the hydrant. Generally, a maximum of 3 lengths of 3½” supply line may be hand stretched back to this hydrant if necessary.

11. Time permitting, a 2½” gate should be attached to the hydrants 2½” outlet for possible

augmentation if necessary. This is particularly effective when the hydrant being used for ILP is nearby (3 lengths or less).

12. The ECC of the ILP should have water supply augmented when the intake pressure drops

below 15 psi. The method selected requires judgment based on fire conditions, location and location of apparatus.

13. The following signals shall be sent from back step buzzer:

One buzzer tone ----------- Emergency stop. Two buzzer tones --------- Hose FF is in position, pumper to proceed. Three buzzer tones -------- Area to rear of pumper is clear for backing up operations and

under proper supervision. 14. ILP is another option in stretching firefighting lines. It may be used in lieu of the back

stretch when conditions indicate that ILP may be advantageous. ILP may be utilized as a supply option when signal 10 – 70 is transmitted.

15. The capacity of a hydrant is a major factor in “In-line pumping” operations. The capacity of

a hydrant is based on many variables (size of main, location within the system etc.). It is important for units to know the capabilities and limitations of hydrants in their response area.


59

7. RELAYING WATER

A relay operation is one in which one pumper supplies water to another. Relay operations can complicate pumping operations because they require coordination between two or more pumpers (potentially accruing higher pressures) and two or more pump operators (necessitating more communication). In addition there is an increased possibility of introducing air into an operating pumper and losing prime. However, if a water relay is warranted, the following procedure shall be implemented.

7.1. Steps:

♦ The Officer or ECC of the operating pumper (normally 1st due pumper), upon finding no viable water source transmits signal 10-70 via Department radio and HT and decides on optimum position of the pumper, factoring such things as easiest hose stretch, ladder company accessibility, fire conditions, collapse potential, etc.

♦ The next arriving pumper, designated as the Water Resource Unit, upon

hearing signal 10-70 must find a viable water source.

♦ The supply pumper connects to a hydrant utilizing either the 10’ or 35’ hydrant connection. The necessary lengths of 3½” hose are stretched from a 3” outlet of the Supply Pumper to the Operating Pumper’s 3” gated inlet on the pump panel side of the pumper.

Both the Supply Pumper and the Operating Pumper must remain in the Volume Position. An exception to this is standpipe operations, where head pressure needs to be overcome. In this case, the operating pumper will operate with its pump in the Pressure configuration. (Supply pumper will still be in volume).

♦ When ready to send water, the Supply Pumper ECC communicates this to the Operating Pumper ECC. Upon confirmation that the Operating Pumper is ready the Supply Pumper ECC should fully open the 3” discharge valve to supply idle pressure. Idle pressure is hydrant pressure plus pressure imparted by the pump at idle (typically 100-125 psi).

♦ This relay procedure should accommodate two-2½” handlines without intake

pressure gauge dropping below 15 psi on the operating pumper. If the Intake pressure gauge reading does drop below 15 psi on the Operating Pumper, then the ECC of the Operating pumper should request the Supply Pumper to increase throttle (tap-up pro-pressure governor) in 10 psi increments as needed.

♦ If the Supply Pumper’s Intake pressure gauge drops below 15 psi, the Supply

Pumper ECC should contact the Operating Pumper ECC and the Incident Commander and inform them that the hydrants supply limit has been reached. must communicate this to the Supply Pumper ECC who will slowly increase throttle as needed.

NOTES

1) Time permitting, a 2½” gate should be attached to the 2 ½” hydrant outlet for possible augmentation if necessary.

2) For operations where head pressures must be overcome (e.g., standpipe

operations) requiring higher pump pressures, the Supply Pumper should be in the volume position and the Operating Pumper must be in the pressure position.

3) In most circumstances, in the volume position the reading on the pump pressure gauge of the Supply Pumper should be around 100-125 psi. (Hydrant pressure 50-75 psi plus pressure of pump in volume - around 55 psi)

4) On some hydrants with high pressures (e.g., parts of Staten Island) the Intake

pressure reading on the Operating Pumper may reach or exceed 150 psi, even if the Supply Pumper is in the Volume position. If the Operating Pumper ECC notes the intake pressure is greater than 150 psi or the automatic intake relief valve discharges (this should happen when the inlet pressure reaches 150-175 psi), he/she should communicate with the Supply Pumper ECC to insure he/she is in the Volume position.

5) If possible, it is better to set up a relay operation before supplying handlines.

6) Officers ordering ECCs to “drop” booster tank water should be aware that in

addition to the possibility of running out of water, it also increases the possibility that the pump may loose prime, necessitating the ECC to shut down lines and re-prime the pumps.

7) The capacity of a hydrant is a major factor in Relay Operations. The capacity

of a hydrant is based on many variables - size of main, location within the system etc. It is important for units to know the capabilities and limitations of hydrants in their response area.

8. SUPPLYING A STANDPIPE AND OPERATING FROM A FLOOR OUTLET

A standpipe system is an auxiliary fire protection system installed in certain buildings/facilities. The requirement of standpipe systems is based on any of the following factors: building height, floor area, and/or fire department vehicle access. While the use of a standpipe system can make for a much more effective operation, it’s imperative that all units follow the following procedure in utilizing this system. 8.1 ECC- Connect pumper to hydrant and charge pump. Stretch 3½" hose line from

pumper and connect to Siamese to supply standpipe siamese. Start water. Augment supply to siamese with second hose line from pumper.

8.2 Control firefighter will proceed to the floor below the fire with a folded length of

2½” hose and the standpipe kit. The Nozzle, Back-up and Door Firefighters (if a five (5) fighter company) will proceed as follows:

♦ Place folded lengths on floor landing below standpipe outlet, or in hallway adjacent to stairway door containing standpipe, with straps facing up and male and female hose butts adjacent to each other. Length with nozzle is placed most distant from standpipe with nozzle facing in direction of stretch. If available and needed, place additional length(s) in the sequence before nozzle.


62

♦ Leave straps connected on folded lengths and proceed as follows: (Photo 8-1)

Remove protective covering from male butts.

Nozzle firefighter connects hose butts between lead length and second length.

Backup firefighter connects hose butts between second and third lengths.

Door firefighter (if present): a) Connects hose butts between 3rd and 4th lengths (if needed). b) Assists Control firefighter in hooking up to standpipe. c) Assists Nozzle and Backup firefighters.

Photo 8-1 ♦ Disengage straps from the folded lengths. The Nozzle firefighter may opt to

take his length up to the fire floor before removing the strap.

♦ Nozzle and Backup firefighters advance the hoseline up the stairway to the fire floor. Hose plays out in the same manner as if it was stretched from the bed of the apparatus. Door firefighter (if present) monitors hose as it plays out to prevent kinks and snags. Control firefighter operates standpipe.

♦ On the officer’s command to start water, the Control firefighter opens the

standpipe outlet valve. Nozzle pressure is controlled from standpipe outlet valve. In order to ensure the proper pressure at the outlet valve, the Control firefighter must remain at the outlet until relieved by the 2nd Engine officer, at which point he can move up and assist in moving the charged hoseline.


63

NOTES:

a. All hoselines stretched from standpipe shall be 2½" hose with controlling nozzle and 1⅛" Main Stream Tip. All hoselines stretched from standpipes shall be connected to outlets on floors below the fire floor. Variations from stretching initial hoselines from standpipe outlets on a floor below the fire due to building configurations shall be approved by division commanders and placed in the CIDS program.

b. If a pressure reducing/restricting device (PRD) is found on the standpipe outlet, it should be removed. If the PRD cannot be removed, and there is no other outlet available without a PRD, than it is permissible to use an outlet with a PRD.

c. Always connect in-line pressure gauge to standpipe outlet to ensure correct nozzle pressure. Pressure gauge can be carried attached to the Control firefighter's length in the same manner as is the nozzle.

d. Controlling nozzle must always be carried attached to the folded lead length.

e. Observe the color of siamese or outlet caps and indicating signs or plates before connecting hose lines. Color markings for the systems are:

♦ Standpipe……………………………………Red ♦ Automatic Sprinkler………………………..Green ♦ Non-Automatic Sprinkler…………………..Aluminum ♦ Combination Standpipe/Sprinkler………….Yellow

To supply the standpipe if the Siamese is inoperable (but the system is otherwise serviceable) or if the Siamese is supplied but further augmentation is required, this can be done by connecting and supplying water to the first floor outlet. To make this connection a 3”x 2 ½” reducer and a 2 ½” double female is required. Another option to make this connection would be to use a 3” double female and a 2 ½”x3” increaser.

f. Before water is started, member controlling supply must personally check connection of hose to proper siamese.

g. If building is equipped with both standpipe and sprinkler systems and standpipe is to be used, the engine company first to arrive must connect first line to standpipe siamese and second line to sprinkler siamese.

h. Another pumper must augment the supply to combination standpipe and sprinkler systems.

i. Certain pumpers in the FDNY are capable of deliver water at high-pressure, that may be need in high-rise buildings. During high-pressure pumping, members must not utilize stairways as staging or rest areas. Utilize minimum amount of personnel in stairways served by standpipes, during high-pressure operations.

j. Exposed male hose butts on folded lengths must always be protected.

k. Photo 2 demonstrates how to carry folded lengths so as to protect the firefighter and others from the exposed hose butts. Note that the folded length is placed with the butts toward the body, minimizing the chance of the butts flopping around (especially in tight quarters like elevators).

9. STRETCHING 2 ½” HOSE UP AN AERIAL

Stretching a line up an aerial is another option available to place a hoseline from the exterior when the situation calls for such. The procedure is as follows:

9.1 Connect pumper to hydrant and charge pump. 9.2 Place turntable of aerial ladder directly below objective. Raise ladder and place it

in position with tip of ladder level with sill..

9.3 Stretch hose from pumper and use controlling nozzle. Arrange hose in folds below turntable.

9.4 Officer climbs ladder, enters window, surveys conditions, and orders line

advanced. Nozzle, backup, and doorman use life belts. The nozzleman climbs to turntable; nozzle is passed up to him. Placing hose under left arm and nozzle over right shoulder, nozzleman climbs the aerial. Backup and doorman follow nozzleman, lightening up on line. Nozzleman snaps life belt on top rung of aerial and passes nozzle and hose in over sill to officer who holds the line. Nozzleman then climbs in the window. Backup continues up, positions at top of the aerial, and snaps life belt on top rung. Doorman positions at middle of the aerial and snaps life belt hook on rung. The Control firefighter positions on turntable to feed hose up ladder.

9.5 When the backup and doorman are locked in to aerial, the nozzleman, assisted by

those locked in to aerial pulls sufficient hose in for operations.

9.6 When sufficient hose is raised both the backup and doorman secure the hose with

hose strap to the aerial, unsnap their life belt, and move up to join nozzleman for operations.

9.7 When hose is flaked out and everyone is in position the officer gives the

command to start water.

NOTES: 1) Hose is placed on left side of ladder as men climb.

2) All members operating on ladders shall wear personal harness or life belts.
