4.0 KERR INTERIOR SYSTEMS LTD. SAFE JOB PROCEDURES POLICY

KERR Interior Systems Ltd. has adopted a strong position on safety and job-site application procedures. The company’s policies have been developed around the requirements of identifying and selecting the job(s) to be analyzed, the breakdown of the basic steps in sequence for a specific job to be analyzed, the identification of health and/or safety hazards in each step, and the determining of the measures needed to prevent and overcome the identified hazards. The Safe Job Procedures are determined from the input of the company’s supervisor(s), the most competent worker(s) familiar with how the job is done, worker(s) who regularly perform the job, and when required people with training and experience on specialized equipment and job procedures. Applicable Legislation Under Section 13 of the Alberta OH&S Regulation, General protection of Workers: 13(2) An employer who develops or implements a procedure or other measure respecting the work at a work site must ensure that all workers who are affected by the procedure or measure are familiar with it before the work is begun.

4.1 ACOUSTIC CEILINGS – INSTALLATION

4.1.1 EQUIPMENT NEEDED Main tees, cross tees, wall mold, hanger wire, screws, Hammer, screwdriver, screw gun, tin snips, measuring tap, pencil, laser level, deck punch or Hilti gun, scaffolding

4.1.2 PPE Gloves, CSA Green triangle boots/shoes, hard hat and any other depending on site hazards, rules or MSDS sheets for products (i.e. dust mask, eye protection)

4.1.3 JOB STEPS 1. Set up proper scaffolding at comfortable height, do not set up so that you have

to reach or bend. 2. Safety glass required if having to drill hangers directly in to concrete 3. Set laser up and do not look directly in the light 4. Hang wires @ 4’on center, with first wires no more than 3’from wall 5. Screw, hammer or drill wall mold in place at height specified on blueprints, wear

required eye wear when drilling or hammering 6. Layout ceiling according to blueprints. String lines and install first 2 rows of main

tees and cross tees, check that ceiling is square 7. While installing Main and Cross tees, ensure scrap material is being placed in

appropriate bins so that potential hazards are not created. 8. Make sure that ties and wires are tightly wrapped, do not leave long loose ends

as this can be a hazard 9. After all electrical and mechanical has been installed, carefully install ceiling tile.

Wear dust mask if dust is excessive 10. Before leaving area or site ensure that all scrap material is cleaned up, and that

there is a safe path to your vehicle when carrying materials out.


4.2 ANGLE AND PEDESTAL GRINDERS

4.2.1 PPE � Always wear eye protection. (Safety glasses under a face shield). � Remove rings, watches and other jewelry. Long hair should be tied back and loose

sleeves should not be worn. Do not wear gloves when operating a buffing, grinding or polishing wheel.

4.2.2 PRE-OPERATION CHECKLIST � Make sure that wheel guards are in place and properly adjusted and tightened. � Don’t adjust a grinder when it is running. � Blotter and wheel flanges used to mount the grinding wheels onto the shaft of the

grinder must be in place. � Tool rests must be adjusted and tightened to ensure that there is less that a 1/8-inch

gap from the wheel. � Wheels should be inspected prior to turning on the power. Wheels with cracks or

chips or that are badly rutted should not be used. They may require dressing or permanent removal from service.

� Check that the speed rating of the grinding wheel is equal to or exceeds the speed rating of the grinder. The maximum approved speed stamped on the wheel blotter should be checked against the arbour speed of the machine to ensure that the safe peripheral speed is not exceeded.

4.2.3 OPERATION 1. Stand to one side of the wheel when turning on the power. 2. Before commencing grinding, allow the grinding wheel to run at operating speed for

a least one minute. 3. When commencing a grinding operation, bring the object into contact with the

grinding wheel slowly and smoothly avoiding impact or bumping motions. 4. Move the object being ground back and forth across the face of the wheel as this

prevents ruts or grooves from forming. 5. Dress the wheel on the face only. Dressing the sides may cause it to become too

thin for safe use. 6. Use the face of the wheel when grinding. Do not press too hard on the wheel. 7. Vibrating wheels should not be used. They must be dressed or replaced or the

bearings of the shaft replaced if they are worn. 8. Do not touch the ground portion of the work piece until you are sure that it is cool. 9. Shut off the power and do not leave until the wheel has come to a complete stop. 10. Clean the work area when finished using the grinder. 11. Disconnect angle grinders from the power source when making repairs or changing

discs. 12. Pedestal grinders, turn off the power switch and lockout the electrical switch before

doing any repairs.


4.3 BAND SAW OPERATION

4.3.1 PPE Safety glasses or goggles must be worn. If a face shield is required, safety glasses or goggles should be worn under it. Do not wear any clothing or jewelry that can catch on parts of the saw blade. It is good practice to remove all jewelry prior to using the saw.

4.3.2 PRE-OPERATION � When hand feeding, the operator’s hands will be close to the blade, therefore a push

stick must be used. � The band saw wheel and all working parts of the blade must be enclosed to prevent

contact points. � Ensure that the blade is properly installed. The teeth of the blade should point

downwards as it goes through the table. � The saw will have a tension guide, which must correspond with the width of the blade. � While the blade cannot be completely covered, the adjustable blade guard should be

installed as close as possible to the work piece. This will prevent contact with the front and sides of the blade.

� The guard that forms the curvature of the feed rolls should cover the nip point. This guard should be installed so that the edge is 9 mm from the plane that is formed by the inside face of the feed roll in contact with the stock.

� The upper blade guide must be adjusted so that it is 6 mm above the work. � Clear away all materials from the table and around the saw.

4.3.3 OPERATION 1. The blade must reach full speed before cutting. 2. Feed the stock at a moderate speed. Do not force the cut. 3. Make several relief cuts before attempting a sharp curve cut. This prevents the

saw blade from binding and possibly breaking the blade or causing it to jump off the wheel guides.

4. Plan cuts to avoid having to back out of long, curving cuts. 5. Before backing out of a cut, shut off the saw and allow it to come to a complete

stop. A band saw may coast for a long time. 6. The operator or another person should never stand on the right hand side of the

table. If a blade breaks it will fly off to the right. Broken blades should be changed only when the power has been shut off and the saw has come to a complete stop. The equipment should be locked out when a blade is being changed or other maintenance work is performed.

7. Sharp curves should only be cut with a narrow blade. 8. Do not twist or apply pressure to the blade. 9. Clear material away from the table only with a stick. Never remove material

from the table with your hands.


10. A clicking sound indicates that the blade could be cracked. Shut off the power and lock out the equipment prior to changing the blade. Change the blade if necessary.

4.3.4 BAND SAW CRACK LIMITS

Band Saw Width Maximum Length of Crack

Millimetres Inches Millimetres Inches Up to 125 Up to 5 1/10 of saw width 1/10 of saw width 125 to 130 5 to 12 13 ½ Over 300 Over 12 19 ¾

1. A band saw with a crack exceeding the limit specified in the above table must be removed

from service until the crack is repaired and the saw re-tensioned by a qualified person. 2. A band saw with a crack not exceeding the limit specified in the table must be removed from

service until the crack is repaired or the lengthening of the crack has been arrested by centre punching or other effective means and the saw re-tensioned as required.

3. A shake bank saw with a crack cannot be used. a. Unless otherwise specified by the manufacturer or a professional engineer, the

minimum rim thickness of a cast steel band saw wheel measured 25 mm (1 inch) inboard from the rim edge must be:

i. 14 mm (9/16 in) for wheels up to and including 1.8 m (6 feet diameter) ii. 16 mm (5/8 in) for wheels over 1.8 m (6 feet) up to and including 2.75 m

(9 feet diameter), and iii. 17.5 mm (11/16 in) for wheels over 2.75 m (9 f t diameter).

b. A qualified person must non-destructively test a wheel over 1.2 m (48 in) diameter for cracks at least once per year.

c. A cracked wheel or a wheel which has been exposed to excessive heat must be removed from service until the wheel manufacturer, or a professional engineer, has certified it as safe for continued use. Never leave a running say unattended. When you are finished using the saw, wait until the blade comes to a full stop before leaving the equipment. With a band saw, especially a large one, this may take some time.

4.7.3 MATERIALS REQUIRED � Strapping the load needs to be done with safety and prevention of product damage in

mind. � The driver is the last one responsible for checking the safety of the load and the truck. � Visualize a plan to strap down the material and equipment safely and with the proper

precautions. � All defective straps should be removed and sent for repair when possible � If you don’t know how to secure a load ask for help from a more experienced employee. � When all safety rules are followed we reduce the risk of accidents, stress, problems, and

unsafe situations

4.7.4 LOAD TIE DOWN AND STRAPPING PROCEDURES 1. Use as many straps as possible on all products 2. Ensure deck and blocks to be ice free.

4.7.4.1 DRYWALL AND STEEL � Belts go over the lift where the dunnage or blocks separate the lifts � Place the belt over the strongest point at each end � At a minimum use 3 straps per lift � Placing the belt in the middle of the lift could cause the dunnage/blocks to fall out over

bumps � If securing various lengths of board and steel belts must be placed at strongest point of

the load ex. (where all spacers line up at each end of the lift. � When the top lifts are longer than the bottom use an extra belt for a wind strap at the

front most part of the lift (towards cab of truck) � All extra material should be removed from deck before leaving yard � Steel has the tendency to shift so only use corners when necessary to eliminate the

chance of a fly off on the road 4.7.4.2 PAILS, BOXES, BAGS, PALLETS AND INSULATION � These products are usually stacked on pallets or loaded right on the deck. These

products have the greatest risk of tip over during travel � Belts usually only cover part of the load so use as many as possible to ensure security of

the load � Corner boards can be used to help secure the load tighter

KERR Interiors Safety Manual 7

� Corner boards will keep the top row of product tight on its pallet � Insulation should be loaded tight when possible to the headache rack and have a secure

bottom. � These products should be shrink-wrapped whenever possible � Use extra straps if worried of security 4.7.4.3 USING TIE DOWN BAR � Inspect bar before each use � Have a firm grip on bar using non slip dry gloves or bare hands � Insert tip completely into tightening hole � Stand firm on a non-slip surface � Use firm grip with body at a right angle to truck, tightening arm to side � With the possibility of your hand or bar slipping which would put you off balance causing

injury. Stand with knees bent for better balance. � If your hand slides off the bar get out of the way so the bar doesn’t come back and hit

you. � Using the proper tie down bar procedure will eliminate the risk falling and injury to body

parts from the bar slingshot. 4.7.4.4 FINAL CHECK � The driver is responsible for the truck, public, passenger and the company. � Do a final walk around checking straps, blocks, tool boxes and for any loose materials. � Ensure all rolled up straps are rolled tight and straight and ratchet lock is engaged (they

can unroll when driving) � Never place ratchets directly above tires when the suspension moves there would be

damage to the equipment 4.7.4.5 WHEN DRIVING � Drive professionally at all times � Adjust driving speed depending on load and road conditions � Keep a close watch on load

4.15 OFFICE PROCEDURES 1) Chair Adjust your chair height so that your elbows are about the same height as the top of the work surface and your thighs are horizontal. If your feet are not resting flat/comfortably on the floor, consider using a footrest Another way to check height is to stand in front of your chair and adjust the height so the highest point of the seat is just below your kneecap Sit so the clearance between the front edge of the seat and the back of your knees just fits a clenched fist Adjust the backrest height so that it supports the hollow of your lower back Tighten the backrest so that it does not give way with body weight Rest your back against the backrest at all times Adjust the height of the armrests so your shoulders are relaxed and your elbows are at 90 degrees 2) Monitor Position the screen away from windows or at a 90-degree angle to the windows Position the monitor directly in front of you Viewing distance should be about one arm’s length away from you (within 30 to 60 cm or 12 to 24 in) Adjust the monitor height so your neck is in a neutral position when looking at the top row of text on the screen Tilt the monitor down if glare is noted on the screen Adjust the screen brightness and contrast for optimal character definition. Ensure the text on the screen is sharp, easy to read and does not flicker If you wear bifocals, it may help to position the monitor lower or tilt it back slightly Every 30 minutes look away from the screen and focus on a distant object Regularly clean the screen; follow the manufacturer’s instructions 3) Keyboard and Mouse Position the keyboard directly in front of you Position the mouse directly beside the keyboard at the same height Position the keyboard and mouse within a comfortable reach so your arms are close to your body while using them Adjust the mouse speed setting. The mouse is harder to control if you use a fast setting Keep your wrist relaxed and straight. Your forearm, wrist and fingers should all be in a straight line. Elbows should be at 90 degrees Hold the mouse loosely with your palm and all fingers Move the mouse with your whole arm initiating movement from your shoulder. Apply a light touch while clicking Use the keyboard and mouse wrist supports for micro-breaks 4) Desk Desk height should be about the same height as your elbows when your arms are hanging straight down when seated Work surface should be large enough to hold work materials. Place frequently used items close to you to avoid over-reaching and twisting 5) Document holder Position the document holder at the same height and distance as the monitor Position the document holder on the same side as your dominant eye 6) Telephone Place the telephone close to you within easy reach on your non-dominant hand side. Avoid cross midline reaching for the telephone


Hold the telephone receiver with one hand. Do not cradle it between your ear and shoulder 7) Environment Lighting should be evenly distributed and should not create a glare or shadows Adjust window blinds or drapes to control light levels and glare Use adjustable task lighting to increase light levels when needed Replace flickering fluorescent tubes and maintain fixtures 8) Changing Water Bottle Remove empty bottle Remove seal on top of new full water bottle Bend at the knees and pickup new water bottle Carefully turn bottle over and place into position on top of water dispenser


4.16 RIGGING

4.16.1 GENERAL Rigging looks like an easy operation that requires no particular skill or experience. But if you have an idea that just anybody can do it, you’re on the wrong track. Too many men have lost fingers or hands or have suffered more serious injuries because they thought, “Anybody can do that.” Important do’s and don’ts to remember:

� Name one member of the crew to act as a signalman, and instruct the equipment operator to recognize signals from that person only.

� The signalman must be careful not to order a move until he has received the “All Ready” signal from each member of the crew.

� The signaller must be fully trained and competent � Each rigger must be sure he is in the clear before he gives an “All Ready” to the

signalman. � When you have positioned the sling or choker you are using, release it, if possible,

before you give the “All Ready” signal � If you must hold the sling or choker in position, be sure your hand is clear of pinch

points. In fact, your hand should be far enough away so there is no possibility of a frayed wire catching your glove and jerking your hand into a pinch point

� Frayed cables will never be used � Watch out for the roll or swing of the load. Since it is almost impossible to position

the hook exactly over the load centre, there will almost always be a swing or roll. Anticipate the direction of the swing or roll and work away from it

� Never place yourself between material, equipment or any stationary object and the load swing.

� Stay away from stacked material that may be knocked over by a swinging load � Never stand under the load, and keep from under the boom � Look over the place where the loading is to be set. � Remove unnecessary blocks to other objects that might fly up if struck by the load. � Load must be placed on a level, even surface � When lowering or setting the load, be sure your feet and all other parts of your body

are out from under the load. � Set the load down easily and slowly so that if it rolls on the blocking, it will be a slow

shift that you can get away from � Identify the designated signalman by the use of reflective vests and hardhats � Use tag lines to control the swing of the load

4.18 ROOF AND FLOOR DECK INSTALLATION Metal Decking is a common application for KERR Interior Systems, and these procedures are applicable when working on metal, wood, or concrete decks. KERR Interior Systems is committed to reducing the risk of falls from heights with several means of protecting workers that are available. Workers are trained to know the various options that are available to protect their health and safety when working on roof decks and near roof edges.

4.18.1 ALERTNESS Most deck installations are done on an elevated structure and the danger of falling is always present. Falls may occur at any time and at any location. Alertness is essential.

Ladders should be securely tied to the structural frame or the scaffolding. Stairs, if available, should be rigidly attached to the building frame.

Access areas should be specially patrolled to keep them free of equipment, material, and debris. Deck edges are sharp. Workers should take precautions to protect themselves from sharp edges or projecting corners. It is very important that the structure be ready to receive the deck. Before deck bundles are placed on the frame, the frame plumbness and connections should be checked. Verify that temporary bracing is in place to keep the frame in a plumb condition until the deck is placed and secured.

4.18.2 FALL PROTECTION TYPES KERR Interior Systems recognizes that there are several fall protection apparatuses available that include guardrails, travel restraints and personal fall arrest protective equipment. Fall protection equipment must be labelled with the Canadian Standards Association (CSA) approved labels.

4.18.3 GUARDRAILS • Guardrails are commonly used on construction sites, as they are a convenient means of

protecting workers. • Guardrails shall protect roof openings and the roof edge. • Guardrails shall be attached to the edge or as close to the open edge as possible. • The guardrail system must be designed to withstand loads that will be applied to them

during roofing operations. • A simple guardrail system can be constructed from dimensional lumber consisting of

standard, top and middle rails and a toe board. • Wooden standards should be placed no more than 2400mm (8ft.) apart and secured to

the building structure. • Well anchored standards are essential to the performance of this fall protection system. • When using wood construction, the top rail shall be laid flat to provide maximum

resistance when lateral forces are applied to it.


• If rails must be removed for material handling, rope off openings using flagging and wear fall restraint equipment.

• Large openings required for services such as skylights, stairwells, roof top units or other equipment will be protected by guardrails during deck installation.

• Smaller openings will be covered with metal deck or plywood during installation. Locations are determined, marked and cut out at a later time.

• Never cut out an opening or proceed with decking past any large or small opening without covering or protecting the opening with guardrails.

• The Prime Contractor is responsible to provide covers or guardrails well in advance of the necessity for covers or guardrails. The Prime Contractors representative must be present to perform the work at the time the safety hazard is created.

• Never proceed past any opening and continue working around this safety hazard. Stop all work activities until the work area is made safe.

• When a smaller opening is covered it must be screwed down or nailed as required. The cover must be marked as follows: HOLE: DO NOT REMOVE

• Serious consequences prevail if covers are not provided in accordance with the above. Contractor(s) and Superintendents have been charged under provincial law for not following this procedure.

• The Prime Contractor or Client must be advised in writing that you have taken the responsibility of covering an opening or providing guardrails and with the completion of work in the area, these safety measures are in place and that the ongoing inspections of them are now his/their responsibility.

• The Prime Contractor or Client must be advised that workers other than deck installers are not allowed on the deck area until all deck is installed and secured. They must be advised that it is safe by a competent deck installer.

• Safety requirements in areas accepted by the Prime Contractor or Client for further work by other trades shall be his responsibility.

4.18.4 TRAVEL RESTRAINT SYSTEMS • Where guardrails have not been provided, a restraint system must be used to restrict a

workers travel distance and prevents them from getting to near the roof edge. • Travel restraint safety equipment is comprised of an anchored lifeline and an adjustable

lanyard that attaches to the workers’ safety belt or harness. • This system allows the worker to travel along the lifeline and incorporates a stop that

holds the worker back from the roof edge. • Some restraint systems use a rope grab that locks at sudden pulls like the seat belt in a

vehicle. • The rope grab may be attached directly to the lifeline without using a lanyard.

4.18.5 TRAVEL RESTRAINT PROCEDURES • All KERR Interior Systems workers are trained and competent in all aspects of sheet

metal application and the safe use of the fall protection system being employed. • Where permanent anchorage points are provided they shall be used to connect the

personal fall protection system. • Where no permanent anchor points are provided, the worker is responsible for the

inspection and installation of a temporary travel restraint anchor. • A temporary travel restraint anchor shall be installed immediately opposite the work area,

in accordance with manufacturer’s written installation requirements. • One (1) temporary travel restraint anchor shall be used for each worker working at the

roof edge. • Travel restraint equipment shall be inspected prior to connecting to the anchorage point.


• Lanyard and snap hook connectors shall be approved and certified. • The travel restraint lanyard shall be connected to an approved rear dorsal D-ring type full

body harness. Safety belts are not accepted. • All work undertaken at an unguarded roof edge must be completed from the kneeling

position, while wearing a personal travel restraint system. • While working or travelling to or from an un-guarded roof edge, workers must keep the

roof edge in sight at all times. Never turn your back or walk parallel to the unguarded roof edge.

• Good housekeeping must be maintained at all times keeping the work area clear of debris.

• No material shall be stacked near the unguarded roof edge. • KERR Interior Systems supervisor(s) are trained to assist workers in safe procedures at

their work stations.

4.18.6 FALL ARREST SYSTEM • KERR Interior Systems roofers must wear fall arrest systems when they are in the danger

of falling more than 3.5 metres (10ft.) or when working above operating machinery, fluids or hazardous substances and objects.

• A fall arrest system consists of a full body harness and a lanyard with a shock absorber. • The fall arrest equipment may be attached directly to an adequate support or connected

to an anchored lifeline. • Fall arrest loads may be high and the lifeline must be sized and anchored to support the

weight of a small vehicle. • KERR Interior Systems workers are provided training by competent and qualified trainers

on the proper use and maintenance of fall arrest systems. • Any equipment that has been involved in an actual fall is replaced with new fall arrest

equipment as the old equipment has done its job and is no longer safe to use. • Prior to use, fall arrest equipment is carefully checked so that straps, buckles and other

hardware are in place and undamaged. • The lifeline and lanyard are inspected for frays, burns, kinds, abrasions and other signs

of general wear or abuse. • The lanyards shock absorber is inspected for torn or missing stitching. The lanyard must

be securely fastened to its D-rings. • The rope grip is checked for proper operation by jerking it suddenly observing that it has

stopped immediately and remains tightly gripped to the lifeline. • Defective fall arrest equipment is taken out of service immediately and is tagged for

repair. • Supervisors, foremen and workers are responsible to inspect fall arrest equipment

regularly. • Equipment that is not in use is stored in clean covered equipment and kept out of direct

sunlight.

4.18.7 OFF LOADING DECK MATERIALS - CONDITIONS AND PROCEDURES • The structural frame must be checked by a competent deck installer for pluming and

alignment tolerances. This will insure that the loads applied by the placing of deck bundles can be adequately withstood.

• Each truckload of deck shall be inspected prior to unloading. Inspect that all bundles are banded, and that the release of the load securing devices will not result in dangerous movement of the bundles.


• Installation personnel shall be competently trained in rigging procedures as related to off-loading metal deck and be familiar with the required hand signals for hydraulic and conventional craning equipment.

• No bundles shall be hoisted on to the steel frame unless they are securely banded. • The Worker(s) on the structural frames receiving bundles should straddle the member

whenever possible. • Bundles are to be landed as close to the structural columns as possible, but not closer than

six feet from any opening or edge so as not to interfere with the laying sequence. • The starting locations and laying sequence must be checked to insure bundles are located in

a manner that will avoid having to turn sheets by hand to accommodate swaging or other special features.

• All bundles are tag lined during the ascent of the hoisting operation. Recommended tag line length is ten feet.

• Decking is normally delivered to the job site as required for installation. However, when site storage becomes necessary, the bundles are to be stacked on wood blocking and be piled or stacked in a manner which will prevent tipping, collapsing or rolling, and prevent any water accumulation in the metal deck flutes or on the plywood bundles.

4.18.8 PERSONNEL PROTECTION • Employees are required to wear or use personal protective clothing, equipment as is

necessary for the employee’s protection from the particular hazard to which the employee may be exposed.

• Safety hats must be worn by employees at all times. • Fall arrest equipment is required to be worn by every employee working on a structure

where there is danger of the employee falling more than 3.5 metres (10 feet). • Safety footwear must be worn at all times. • Eye protection shall be worn by employees in all work areas where eye injury due to

flying particles, hazardous substances or harmful rays such as welding and cutting operations may exist.

• Welder’s helmet or a full face shield shall be worn as applicable. • Proper work gloves are worn by employees handling sheet steel elements.

4.18.9 HOUSEKEEPING • All steel roof deck cuttings, strapping, packaging material, and other debris pertaining to

steel roof deck shall be removed from the roof area each working day and disposed of in a suitable manner.

• All cuttings, strapping, packing materials and other debris pertaining to the metal deck, are cleaned-up and disposed of in a suitable manner each working day or removed to a disposal or storage area as often as necessary to prevent hazardous situations.

• All loose bundles of structural sheet steel deck, wood, and crates are secured at the completion of each working day.

4.18.10 SEQUENCE OF LAYING DECK (The following procedures relate to flat roofs.)

1. Spot your first set of bundles along the edge of the roof or floor you intend to start with. Spot additional bundles out far enough to use up sheets in first set of bundles. (e.g., first bundle contains 20 sheets, second bundle should be spotted approximately 60' in from the edge, and so on).


2. Before opening any bundles of deck the Foreman should evaluate weather conditions and decide if weather is suitable for safe deck installation.

3. After deck is spotted, start laying deck by having two men with harnesses and lanyards position themselves on either end of the first bundle of deck. Tie off to steel.

i. Both men will measure in from the perimeter angle far enough that a full line of sheets can be installed (usually 6' to 9' depending on conditions). Mark steel with a felt marker.

ii. Open bundle of sheets and position first one on your mark; clamp in place with two “C” damps.

iii. Install two to three sheets, enough to create a good work platform. 4. It is important that two men must place the deck when working on open steel. The only

time one man can handle a sheet of deck by himself is when you are dragging the deck over a finished area. While tied to an anchor point that can withstand 5000 lbs., one man lowers a rope to pull up welding cable and accessories. The other man can assist by coiling cable on your established work area. When there is a sufficient amount of cable on the roof, clamp the cable to the perimeter angle to secure it.

5. Before the ground man comes up to the roof, test the stinger for spark. 6. Repeat step 3 above, until you have a complete walkway the width of the building. 7. When you are sure the deck is straight, the welder can tack down the walk way. The

weld should not be too close to the lap so you can back lap the sheets in where the bundles are sitting.

8. You can start laying deck with 2 men. Start on the bundle at the edge of the roof; lay out enough deck so you can measure to the first rafter.

9. The second and middle bundles can be laid out with one man per sheet checking that the lap is done with male lip of sheet to male lip, and female to female.

10. After you complete each full section of deck, measure to the rafter and adjust accordingly. When it is straight, the welder can tack that line and weld at least 1 row through the centre of each course of sheets in the event that wind picks up.

11. Place chalk lines (preferably using red chalk) on either side of the joists to minimize burning holes in the sheets. This also assists in the welding process.

12. Continue across the roof one bay at a time. DO NOT get too far ahead of the welder. 13. In winter, stop laying deck after the afternoon coffee break. Start crimping and painting

deck to completion by the end of the day. In case of snow, this avoids sweeping the deck.

14. Crimping: a) Check the blueprint to determine the amount of distance between each

crimp. b) Be sure weight is on the overlapping sheet. c) The tooth on crimper should be facing the direction of installation. d) Crimp the sheet by using outward force on handles of crimper. e) Test the first couple of crimps by putting force on the under-lapping sheet to

see if there is any movement. Check crimps periodically hereafter. 15. Painting of welds is done with a brush taped or wired to a stick to enable a person to

paint without bending over. Apply only enough paint to fully cover weld. When welding and painting the perimeter, install a safety line. Tie ends securely to structural steel. Workers are to tie off to this safety line when working on the perimeter edge.

4.18.11 SAFETY NOTES � Be sure that rigging is adjusted to keep hoisted loads well balanced. � Do not stand under loads being hoisted. � Keep loads in view. � Use proper hand signals to crane operators.


� Check erection drawings to land deck in proper position and orientation to avoid turning deck.

� Make sure bundles are secure and stable before cutting bands. Pay particular attention to the following:

a. DO NOT USE single span bundles as working platform, especially to cut bands. b. Sheets could shift due to handling. Insure bottom sheet extends past the support at

both ends, otherwise place where full support can be obtained. c. When cutting bands on bundles use both hands and stand well back - bands are under

tension eye protection is recommended. PAY SPECIAL ATTENTION TO SHORT UNITS OR SINGLE SPAN UNITS

• Make sure deck is firmly secured before using it as a working platform. • Make sure cut outs and openings are adequately supported and guarded. • Use chalk lines to locate supporting steel - measure accurately. • Be alert for sharp edges. • Wet deck is inherently slippery - watch your footing! • Keep a litter/clutter free work place. • Wear eye protection when near welding. • When installing galvanized deck on sunny days, sunglasses and sunburn protection are

advisable. • Stay alert!

4.18.12 USE OF STAIRS AND LANDINGS • Whenever stairs and landings are part of the structure being erected, they should be

installed along with the structure to make access for bolting, welding and deck installation activities safer and less strenuous.

• Design consideration for this should be done during the initial stages of project design.

4.18.13 LADDERS • Ladders must be in good condition and extend at least one meter (3ft.) above the

landing area. A wooden plank platform may be necessary where materials such as bolts are pulled up by hand.

• Ladders must be correctly placed so that they can access a point of connection to a fall arrest system or an access platform.

• Ladders can be used to access vertical columns or other areas in which the top of the ladder cannot be tied off. Another worker will hold the base of the ladder steady while the worker is on a ladder which is not tied off.

• Where possible, the worker will connect a fall arrest system or attach to an existing fall arrest system.

• Access ladders are to be erected as per the OH & S Code requirements.

4.18.14 LIFTING/LIFTING METHODS • Steel joists must be securely attached at their bearing ends and have their bridging

completely attached. Verify the structure's capacity to carry the deck bundles. • The bundles must be rigged for lifting so that shifting and excessive tipping will not occur

and so the lifting device will not damage the deck. • All lifting equipment must be adequate for the job. • The hoisting operation must be properly directed and manned.


• Tag lines attached to the bundles (not to the bands) will help workers control and position the load.

• Never move bundles by pulling on the strapping. If possible, spread deck bundles out along the building column lines to create several small stacks rather than stacking all the bundles in one area.

• Workers should be instructed to keep the load in sight until it is safely placed on the structure.

• Bundles should be landed so that the ends of the bundles rest on a bearing surface rather than having both ends cantilevered.

• Bundles should be positioned for convenient spreading of sheets and oriented so individual deck sheets will not need to be turned.

• Bundles of deck which have been un-banded must be secured to prevent individual sheets from being blown off the structure.

• Steel roof deck is designed primarily to support uniformly distributed load. Care shall be taken to avoid excessive concentration of loads during the temporary storage of materials for sub-trades.

• All steel roof deck being hoisted to the working level shall be adequately banded and carefully slung employing steel wire rope and a choker type sling or multi-lift beams.

• All steel roof deck sheets, after being laid and aligned, shall be properly secured in place prior to leaving the jobsite at the end of each working day.

• All loose bundles of steel roof deck sheets shall be secured at the completion of each working day.

4.18.15 SAFE WORK PLATFORM • To make the working platform safe and prevent deck damage, the deck units should be

attached to the frame and side laps connected as soon as possible. • If deck sheets are temporarily used to access bundles, they must be end bearing (not

canti-levered) and must be securely attached to the frame to prevent slip off. • A working area should be at least 12 feet wide. It is recommended that a working area

be established around or along each bundle so that the bundle can be safely accessed. • The platform can then be extended in any convenient direction. • Specific jobs requirements need to be considered to determine deck erection starting

points and erection progression. • As the platform is extended it will necessary for at least one worker to work from the

structural frame. • OH & S standards require that employers provide fall protection during deck erection

operations and all OH & S guidelines for safety while erecting deck must be followed. • Caution is required by anyone on the deck when it is wet as the deck surface is

inherently slippery in this condition.

4.18.16 PLACING DECK • As the deck sheets are placed, one edge of the deck will always be "open" or leading.

This leading edge should only be approached in order to place the next sheet. • Workers should also maintain a safe distance (6 feet if possible) from the end of the deck

unit. When aligning the edge (side) lap, the worker should kneel. Kneeling lowers his center of gravity and decreases the chance of falling.

• As soon as possible after erecting the deck, the edges of the building and of all openings must be protected with cables, fencing or other OH & S required warning and protection devices.

• A floor hole must be protected with a cover, secured against accidental displacement, of OH &S standard strength and construction.


• When the cover is not in place, the hole should be protected by an OH & S standard railing.

4.18.17 OTHER TRADES • Other trades should be kept off the working platform and the area immediately below the

working platform during the deck erection process. • Care must be taken when cutting bundle straps to prevent straps or dunnage from

dropping onto personnel or equipment. • Workers will be instructed on all aspects of deck safety before any deck is installed from

supervisors and foremen at the job site.

4.18.18 FASTENING AND INSTALLING DECK • Deck is installed in accordance with the Approved for Construction drawings. The deck

must be installed by qualified and experienced workers. • The beginning point should be carefully selected for proper deck orientation and edge of

roof or floor slab location. • Maintaining rib or flute alignment across the structure is very important. A snap chalk

line should be used at reasonable intervals to assure proper alignment of deck panels. • Panel cover widths must be maintained to achieve long straight runs of deck. • Roof deck is often left exposed on the bottom that requires alignment to be parallel to

the girders at all girder lines to prevent unsightly conditions. • Floor deck flutes should, if possible, maintain alignment to achieve continuous concrete

ribs across abutting sheet ends, minimizing concrete leakage. • Flutes that do not align can create closure problems that may interrupt the slab design. • Proper alignment can only be achieved by proper adjustment of each deck panel as it is

placed. Cover width errors accumulated across the deck cannot be corrected with the last sheets in the run.

• On-site experience has demonstrated that the frequency of snapping a chalk line determines the accuracy of rib and flute alignment. This minor effort at the time of deck placement eliminates the need for field corrections.

• For deck to perform its design functions and serve as a working platform, it must be adequately and properly attached. The deck can be used as part of the horizontal bracing system and the fastening method, and pattern have been selected to provide a certain strength and stiffness in the plane of the deck.

• Fastener type or pattern requires the approval of the designer. No substitution should be made without that approval.

• Deck fastening to the structural frame can be accomplished with welds, self-drilling screws, air drive, or powder driven fasteners.

• A minimum of 1 1/2" of end bearing should be provided for deck. If there is less than 1 1/2" of bearing, additional fastening should be provided and the deck end load capacity should be checked.

• For deck that is intended to end lap (roof deck), the end lap location should be adjusted so the center of the lapped portion occurs over the support or, when supported by bar joists, over a top chord member.

• All operators of powder actuated tools must be qualified operators. Air actuated tools require trained operators that are familiar with all safety procedures.


4.18.19 STORAGE OF MATERIAL ON SITE Areas for storage shall be provided by the Prime Contractor as close to the building as is practicable.

• Protection against damage shall be provided by the Prime Contractor. • Steel roof deck shall normally be delivered to the jobsite as required for erection, but

if site storage becomes necessary, the following requirements shall be observed: 1. tilt bundles for drainage 2. block bundles off ground for effective drainage and ventilation 3. block long bundles to prevent sagging

4. store away from chemically corrosive substances (e.g. salt, cement, fertilizer) away from materials that could contaminate the surface (e.g. diesel oil, paint, grease) away from site traffic

• If bundles are to be covered, avoid impermeable material such as plastic and ensure that adequate ventilation is provided to prevent condensation. Moisture can cause wet storage staining of deck material.

6. The site Supervisor will ensure that: a) The spoil pile is kept a minimum of one meter from the edge of excavations that

are deeper than 1.5m (5 feet) b) Heavy vehicles or objects are kept away from the excavation a distance equal to

the depth of the excavation unless the shoring has been certified as being able to withstand such weights

7. Employees will not place or stack tools/materials near the edge of the excavation where their falling could cause injury to the employees in the excavation

a) Employees installing shoring, stringers or bracing will use a ladder and work downward from the top of the excavation, installing each brace in descending order

b) When timber shoring is used, it must be installed progressively as the trench is being excavated

c) Employees removing shoring, stringers or bracing will use a ladder and work upward from the bottom of the excavation, removing each brace in ascending order

8. The company will provide for each trench more than 1.5m (5 feet) in depth in which employees are working, not less than one ladder for each 15m (50 feet) of working length of the trench or fraction thereof and the ladder shall extend at least .9m (3 feet) above the top of the trench

9. No more trenching than absolutely necessary will be left open overnight. When trenches are left open, they must be barricaded or guarded to protect the public and employees (see attached)


4.22 VAPOR BARRIER INSTALLATION

4.22.1 EQUIPMENT NEEDED Insulation, vapor barrier, acoustical caulking, knife

4.22.2 PPE Gloves, CSA Green triangle boots/shoes, hard hat and any other depending on site hazards, rules or MSDS sheets for products (i.e. dust mask, eye protection)

all joints 7. Wash well after completing job.


4.23 WELDING, CUTTING, AND BURNING Work involving welding, cutting and burning can increase the fire and breathing hazard on any job and the following must be considered prior to the start of work:

1. Only adequately trained/competent workers are to do any job that pertains to welding, cutting or burning

2. Always ensure that adequate ventilation is supplied since hazardous fumes can be created during welding, cutting or burning. If natural ventilation cannot be achieved, artificial ventilation must be provided, i.e. electric fans

3. Where other workers may be exposed to the hazards created by welding, they must be alerted to these hazards, i.e. welders flash. Appropriate precautions must be taken, i.e. welders screens, or workers must wear CSA approved dark safety glasses

4. Welders must wear CSA approved welders shield. The shield must be attached to a fiber metal hardhat

5. Always have a 20 lb ABC fire extinguisher near when welding, cutting or burning 6. Never work in an area that flammable materials are present 7. Flashback arresters must be installed on all hoses at the regular end 8. When there is a risk of welder’s spark falling from one floor to the ground, the area

below must be adequately taped off, i.e. deliniar tape. If this is not possible, a welder’s blanket must be used

9. Check all hoses for damage before beginning work. Cracked or broken hoses can cause a fire hazard. Do not use damaged hoses

10. Do not use tape to fix cracked or broken hoses 11. Never weld or cut lines, drums, tanks, etc. that have been in service without making sure

that the containers have been adequately cleaned. Without checking, this could cause a fire or explosion hazard

12. Never weld, cut or burn in a confined space without proper tests by a trained/competent worker has been carried out
