SAFE WORK PROCEDURES

Safe Work Procedures

General:

A safe work procedure is written step-by-step description of how to do a job from start to finish. It is a

reference particularly to jobs, which are either uncommon or not performed often, or jobs requiring

uniformity, or jobs which can be hazardous and require guidance.

GRD Construction Ltd, Promotes worker safety through the following:

- Putting safe work procedures in writing.

- Making them available to all employees.

- Provide safe equipment, tools and materials.

- Require that supervisors enforce the use of and compliance with these job procedures/

- Involve workers in the development of job procedures.

GRD Construction Ltd. Safe work procedures will comply with legislated requirements and manufacture’s

specifications.



COMBUSTION ENGINE INDOORS

Procedures:

When working with Petroleum (gasoline, diesel, and propane) Powered Equipment (bobcat, concrete

saw, quick cut saw, concrete finishers, etc.…) in indoor environments there is always a risk of elevated CO

levels. A Risk Assessment should be conducted to determine if there is a potential for the build-up of CO.

If there is a risk the following procedures must be followed.

- If possible use local exhaust ventilation systems to remove the exhaust to the outside.

- Ensure that there is adequate ventilation. Use dilution ventilation (force fresh air into the work

area), this will reduce the build-up of CO.

- Use continuous CO monitoring instrument to ensure that worker are not exposed to elevated

levels.

- When and if the Co monitor indicates elevated levels, the area should be evacuated until levels

return to normal.

Information on Carbon Monoxide:

Carbon Monoxide (CO) is a product of incomplete combustion; it is a toxic, odorises, invisible gas. When

the symptoms are mild the victim may not link them to Co poisoning.

The symptoms associated with CO poisoning include:

- Headache

- Nausea

More severe poisoning symptoms include:

- The previously mentioned symptoms becoming worse.

- A progression to mental confusion.

- Finally coma and death

CO produces its effects by interfering with the ability of the blood to carry oxygen to the tissues and more

importantly the brain. Normally, oxygen is transferred from the lungs to the blood where it combines

with the hemoglobin to form oxygenated red blood cells. CO is also transferred from the lungs to the

blood where it forms a carboxyl hemoglobin (COHb) or a CO enriched blood cells. The attraction and

combination of hemoglobin with CO is approximately 200 times greater than for oxygen so that CO

replaces oxygen form blood and then prevents further uptake of oxygen by the blood. As long as CO

continues to be breathed it progressively blocks more and more of the blood oxygen carrying capability.

Even a low concentration of CO in the air can produce a high level of COHb and asphyxiate the exposed

worker by cutting off the vital supply of oxygen to the tissues,



Fortunately the effects of CO poisoning are not generally considered chronic. CO levels in the blood tend

to drop as soon as the worker is removed to fresh air and removed from CO exposure. More extreme of

Co poisoning require a higher concentration of breathable oxygen to rid the body of Carbon Monoxide.

Frist Aid measures in the event of CO poisoning:

1. Remove the victim to fresh air.

2. Keep them warm and at rest. Activity can worsen the effects of CO by increasing the demand for

oxygen.

3. Take them to hospital. There, they can receive enriched oxygen to accelerate the removal of Co

from the blood.

4. If the victim is not breathing, start artificial respiration. If there is no pulse start CPR and have

someone call 911.

GAS CUT-OFF SAW

Key Safe Procedure:

The operator shall refer to and not operate the Gas Cut-Off Saw until they fully understand written safety

direction, precautions, safe operation methods and rules described in the user`s manual. The operator

shall ensure the gas cut-off saw is operated in accordance with instructions and or directions described in

the user`s manual.

PPE Required

Eye protection

Steel Toed boots

Hard hat

Hearing protection

Dust mask for particles

Work gloves

Starting procedures:

1. Place the engine ON-OFF switch to the ON position.

2. Conduct a hazard assessment before using the equipment.

3. Ensure area around saw is debris free and no underground utilities are near.

4. Ensure proper PPE is being worn.

5. Using your thumb, press down on the throttle lock lever, while squeezing the throttle trigger. This

will lock the throttle in the half-throttle position.

6. Pull the chock lever all the way out to the closed position.

7. Pull the decompression button outward.

8. Place the saw on level ground. Make sure the saw blade is free to rotate and will not come into

contact with any foreign objects.

9. Hold the front handle firmly with the left hand and put your right foot onto the base of the rear

handle.

10. Grasp the starter grip and slowly pull it out. The resistance becomes to hardest at a certain position,

corresponding to the compression point. Pull the starter grip briskly and smoothly for starting.

11. If the engine has started, slowly return the chock lever to the open position. If the engine has not

started-repeat the above steps.

12. Squeeze the throttle lever trigger to release it from half-throttle position.

13. Before the saw is placed into operation, run the engine for several minutes. Check for fuel leaks and

noises that would associate with loose guards and – or covers.



Note: The closed position of the chock lever enriches the fuel mixture for starting a cold engine. The open

position provides the correct fuel mixture for normal operation after starting and for restarting a warm

engine.

Operating Procedures:

1. Always cut with the saw full throttle

2. To begin sawing, lower rotating blade allowing it to cut the present depth.

3. When blade has reached full cutting depth, slowly walk behind the saw at a rate that will allow the

engine to operate without losing optimum RPM. Do not try to cut faster than the blade will allow.

4. When the end of the cut has been reached, raise the blade out of the cut.

5. If cutting is complete, turn the engine off and wait for the blade to stop rotating.

Shut Down Procedures:

1. Let the engine idle for 3-5 minutes

2. Place the engine On –OFF switch to the OFF position

3. Wait for the blade to stop spinning before handling the saw.

4. DO NOT touch the cutting blade it is VERY HOT! Allow it to cool.

Fueling Procedures:

1. Do not attempt to fuel equipment when engine is hot or running. Do not smoke while refueling.

2. Remove the fuel cap located on the side of the saw.

3. Visually inspect to see if fuel level is low.

4. If fuel is low replenish with proper fuel.

5. When refueling, be sure to use a strainer for filtration. Do not top-off fuel.

6. Wipe up any spilled fuel.



FALL PROTECTION PROCEDURE

General:

The term “Fall Protection” relates to both the use of safety harness attached to a lifeline or guardrails for

the purpose of the GRD Construction Safety Program. All workers are obligated to use fall protection.

When working at height of 3 meters (10 ft.) or more in height.

Where a fall from a lesser height involves an unusual risk of injury (I.e. risk of falling onto

operating machinery or into a trench)

When working on a desk/floor edge or near a floor opening which present a combines falling

hazard in excess of 3 meters (10 ft.)

The authority having jurisdiction over safety legislation may allow the use of specific safe work

procedures as a means of fall protection where an unusual risk of injury exists. (Note: in all cases where

fall protection is required, the safety regulations put in place by the authority having jurisdiction shall be

consulted and adhered to)

Guardrails

When guardrails are used, they are to be installed consisting of a top rail, intermediate rail, and toe board

where applicable.

The top rail shall be a maximum of 107 cm (42 inches) high.

The intermediate rail is to be positioned midway between the top of the toe board and the top

rail. The top of the toe board shall be minimum of 140 mm (5.5 inches) above the working

platform.

Vertical supports for handrails shall be spaced no more than 2.44 meters (8 ft.) apart unless

otherwise specified by the safety authority having jurisdiction.

Where a guardrail has to be removed to accommodate work, the workers involved in that work

shall wear and use alternate fall protection and when the work is completed, the guardrails shall

be replaced.

In Alberta:

No specific definition of guardrails provided, however, follow the procedures as defined above. Guardrails

must be installed if the platform, mezzanine, etc… is 1.2 meters (4ft) above the adjacent floor or ground

level.

Toe boards are too installed if there is a danger from falling tools from the platform, mezzanine.

In British Columbia

Toe boards need to be present if there is a risk of falling tools from the platform, mezzanine, etc. The top

of the toe board must be at least 10 cm (4 in) above the floor. If there is no toe board installed, then the

intermediate rail is to be positioned midway between the top of the platform and top rail. Guardrails

must be installed if the platform, mezzanine, etc… is 122 cm (4 ft.) above the adjacent floor or ground

level.



Harness The term “Safety harness” for the purpose of this procedure refers to a full body harness with the “D” ring

located on the back of the harness. A full body harness shall meet CSA Standard CAN/CSA Z259.10-M90 Full

Body Harness- in Alberta and British Columbia.

Inspection/Maintenance

Competent persons shall do all inspection and maintenance monthly.

Inspection and maintenance applies to safety harness, lanyards, lifelines and connecting hardware. When

workers use fall protection equipment, they are to be instructed in the proper storage and maintenance of

this equipment when not to use.

Lifelines and webbing material shall not be just rolled in a hall and set aside, but stored in such

manner to allow the air to freely circulate around them to prohibit mildew or rotting.

Lifelines are to be kept free from substances such as chemicals and grits, which will contribute to their

deteriorations.

All metal parts are to be given a visual inspection from distortion/damage that could affect the safety

of the equipment.

When a piece of this equipment has been subjected to stress from a worker falling or found to be

damage/cut in any way, then the equipment is to be removed from service until the manufacture or

professional engineer has re-certified it as being safe to be put back into service.

Floor, Roof and Shaft Openings:

When work is commenced in or around a floor, roof or shaft opening, wither a properly guard railed work

platform shall be supplied with safe access and egress, or personal fail protection equipment shall be worn

and correctly used by each worker and attached to wither a fixed anchor or safety line. Properly guarded

refers to being guarded by a perimeter guardrail as described in the guardrail section of this procedure or a

temporary covering, secure in place, capable of supporting a minim of 2.4 kilo newton’s per square meter

or the weight of any load intended to be imposed upon it. A temporary covering shall be clearly marked

indicating the hard and the covering is not to be removed.

Elevating Work Platforms:

While using any type of elevating work platform, and remaining inside the confines of that platform, all

GRD Construction employees will use their safety harness and be the securely attached by lanyard wither

to a field anchor point or to a properly anchored safety line.

PLEASE REFER AND READ GRD CONSTRUCTION, FALL PROTECTION PLAN SPECIFIC FOR EACH JOB SITE IN

THE JOB BINDER PRIOR TO WORKING AT THAT JOB SITE.



REINFORCING STEEL General:

During construction, it may happen that because of future concrete walls, etc., to be installed reinforcing

steel may be left protruding from the concrete.

When workers have to work in, around and above this projecting rebar material, it cannot be jus bent

over to eliminate the hazard

Procedure:

To recognize and control this hazard, some form of guarding shall be in place on the “rebar” to protect

the workers from accidentally falling on this rebar or otherwise receiving an injury.

Steel of this nature has no real pattern, but guarding of the projecting rebar can be done in at least two

ways.

1. Single pieces or small numbers of rebar can have plastic caps placed on the top of each

protruding bar.

2. Where there are rows of rebar (such as required for concrete block walls) protruding from the

concrete “V” channels constructed out of three pieces of 2” x 4” are to be places along the tops of

the rebar to protest the workers. The channels should be secured in place after setting them in

position.



WIRE ROPE MAINTENANCE General:

To maintain wire rope in serviceable condition, it will always be inspected before use. These inspections

should be made sooner should the general appearance of a particular rope give indications of the need

for more frequent or through inspection. All rope that has been idle for a period of a month or more due

to a shutdown or shortage of the machine on which it is installed shall be given a thorough inspection

before being put back into service. The inspection should cover all types of deterioration

Inspection:

Inspection should be made before the rope is used for the first time on any particular day.it should

cover the eye and the portion of the ropes used most in daily operation. The eye (dead end of the

rope where it is fixed to the broom) should be inspected thoroughly for abrasion, corrosion, broken

wire and loose or servings/seizing (serving/seizing the small wire which is wrapped around the wire

rope to present fraying at the end of the non-rotating wire rope) Inspect the remainder of the rope

length normally used showing kinks, sharp bends, or any evidence of damage or excess wear.

The inspection also requires a thorough inspection of the entire rope length. Watch for greater wear

at the eye en of the rope. To remain in service, the rope should be reversed on the drum so that the

wear will more nearly equalize along the entire length of the rope.

Rope Replacement:

It is very difficult to determine when to replace wire since many factors are involved. Proper

determination of a wire rope depends upon the good judgement of an experience person in evaluating

the remaining strength in a used rope after allowing deterioration disclosed by inspection.

Sufficient reasons for considering rope replacement.

Six randomly distributed broken wire in one rope lay or three broken wires in one strand in one rope

lay.

Wear of one-third the original diameter or outside individual wires.

Kinking crushing, bird caging, pining (flattening of strands) or any other damage resulting in

distortion of the rope structure.

Reductions from new condition nominal rope diameter of more than 1/32 of an inch.



Maintenance procedures:

Care is required in the handling of wire rope to prevent damage to the rope or the individual wire strands

which will affect the overall strength and performance of the rope. The formation of kinks should always

be prevented as this displaces the strands of wire from their original position and relation to each other,

causing ever bending and unequal tension in the strands. This distortion cannot be corrected, even under

the nigh tension. A permanent weak spot remains in the rope. Displaced or raised wires indicate a

previous kink, but will not show the extent of the damage to the inner rope wires.

Wire rope should never be pulled over a non-operating support such as a spindle bar, a pin or an

inoperative sheave. This practice causes severe abrasion to the outer strand wires

A properly operating sheave or snatch block is essential to safety and to the long life of the rope. The use

of warn sheaves with flat grooves should be avoided since they do not provide sufficient support to

prevent the distortion and flattening of the ropes as it passes over the sheave.

Sheaves having nicked or broken flanges are likely to have cut otherwise damage the rope and should not

be used. An even distribution of wire rope coils over the hoist drum is essential to smooth operation and

to prevent rope from cutting down through or crushing other coils on the drum with resultant damage to

the rope in unreeling rope.



POWER LINE & UNDERGROUND HAZARDS General:

Power lines are closely regulated by legislation. Occupational Health and Safety Regulations require you

to stay clear of power lines. Do not go to close with people, equipment or material.

The limits are outlined in the regulations. Depending on the voltage of the power lines, you need to

establish a safe working distance and make sure everyone follows those guidelines.

Procedure:

1. Do a hazard assessment. What equipment will you be using? Will your work area be too close to

the power lines? Are the materials and building components being used awkwardly and at a risk

due to power line closeness?

2. Notify the power company for disconnection or relocation of the line if needed or have the line

isolated or de-energized.

3. UNDER NO CIRCUMSTANCES SHALL WORKERS (OTHER THAN QUALIFIED, PROPERLY

INSTRUCTED WORKERS WORKING IN AN EMERGENCY SITUATION) WORK, MATERIALS BE

STACKED, OR TOOLS AND EQUIPMENT BE OPERATED IN PROXIMITY TO POWER LINES WITHIN

THE LIMITS OF APPROACH SPECIFIED IN THE FOLLOWING TABLE- UNLESS WORKERS ARE

PROTECTED IN ACCORDANCE WITH WCB AND/OR OH&S REGULATIONS.

I. VOLTAGE: Minimum Distance

a. V to 75KV 10 feet

b. Over 75 KV to 250 KV 15 feet

c. Over 250 KV to 550 KV 20 feet

Ii *Regulations applicable in British Columbia and Alberta.

4. Sufficient distance shall be added to the specific distance to prevent unplanned or accidental

movements bringing the worker, tools, equipment, including booms, hoisting cables and any part

of the load being raised. Distances shall be increased to provide for any change in boom angle ,

swing of the hoisting cable and the load while it is being raised, lowered or moved laterally to

ensure that safe distance is maintained at all times. Operators shall give consideration to the

probability of hazard from switching surges, altitude, humidity, line configuration, etc.

5. When power lines are encountered within a work area, alert your supervisor. The supervisor will

ascertain the voltage and minimum distances required and take the necessary precautions and

documentation.



6. When job circumstances require that work be done closer than the limits of approach stated

above, the following procedure must be followed prior to commencing work.

7. An assurance in writing must be obtained from and signed by the person(s) controlling the

electrical system. The assurance must be state that during the work period, the electrical

conductors will be de-energized or effectively guarded against contact, or displaced / re-routed

from the work area. The assurances must be available for inspection on the project site.

8. Use a trained assistant for signaling

9. Keep an eye out overhead at all times.

10. Look out for uneven ground that may be cause your vehicle to bounce or weave.

11. Never ride or climb on equipment or a load when near a power line.

12. Do not ground your equipment or a load when near a power line

13. Remember, electricity is invisible- don’t take any chances.

14. If a power line comes in contact with your vehicle, stay in the vehicle until help arrives.

15. If you strike a power line, call the power company right away. Report the details of the incident.

The company will inspect and repair the area. You also need to report the incident to the head

office, WCB and/or OH&S.



PROPANE / ELECTRICAL HEATERS General:

Although heaters are very valuable in construction, they can be a dangerous tool if not used properly

and supervised at all times. Never leave a heater of any type unattended for an extended period of

time and always ensure that heaters are not placed too close to people, equipment or material that

could catch fire.

Procedure:

1. All temporary heaters must be located on a stable surface.

2. Propane cylinders less than 300 lbs., may be used indoors during temporary construction.

3. A first stage regulator is required at the propane tank end to reduce the high pounds down to the

low pounds for the heater. Regulators shall be provided with the propane tank.

4. Temporary heaters must be at least 6 feet away from the fuel cylinder.

5. Hose length shall be minimum of 10 feet (3 m) and maximum of 50 feet (15 m)

6. Fire extinguishers must be located within 30 feet (10 m) of a heating unit.

7. Connecting and reconnecting of moved propane tanks must be done by a worker trained and

certified to do so.

8. Carbon monoxide poisoning is a potential hazard of temporary heating. The most obvious

symptom of Co poisoning is headaches. If you suspect high levels of CO notify your foreman.

9. If using electrical heaters, make sure you are using a proper electrical cord.

10. Electrical cord must be free from damage, such as tears or fraying.

11. And cords that present a tripping hazard tape down or put up signs to alter workers to the danger

of tripping.



WORKING ALONE

General:

Prior to working alone on any specific job site, the work and condition of work must be discussed within a

supervisor.

It is highly recommended that you not leave a column with any sizeable web standing over night

without being tied in to a structure temporarily braced.



Procedure:

1. Complete hazard assessment form and discuss with workers prior to commencing work

2. Know the weight of the column, to be erected and be sure it is within the capacity of the lifting

equipment.

3. Use appropriate rigging. Inspect all rigging prior to use.

For light columns a beam clamp on the top works well, but be sure not to side load a beam

clamp as this could cause it to fail with loads far below its rated capacity.

For heavier columns, a wire rope sitting double wrapped with a choke is a good choice. If the

column is on the lighter side with girl clips than a wire rope with a single choke works, well if

choked under a girl clip.

Always rig a column with the choke on the side of the web not on the flanges. This will ensure

that the column stands fairly straight once in the air and this greatly help with positioning of

the column on the anchor bolts.

Never use a cloth sling to erect a column unless it’s a HSS column that has no sharp sides.

4. If using a crane set it up as a close to the column and its anchor bolts as possible. This is for

reduce the length of boom needed as lifting column can side load a boom very fast. This can be

extremely dangerous. Be sure to allow room for a man lifting or a smaller column a ladder to be

able to disconnect the rigging. If using a forklift try to limit the distance you will need to travel to

as short as possible.

5. If lifting with a work lift, drive the lift in a direction that reduces any side loading of the boom and

be sure to get the hook over the center of the column before lifting it off the ground the precent

the column base from swinging out.

6. If lifting with a crane, the same idea applies. Be sure to swing with the column as it comes off the

ground and try to keep the ball over the top of the column and level.

7. Once the column comes off the ground, keep it low and have a swamper hold the bottom as the

lifter positions the column over the anchor bolts.

8. When properly positioned, slowly let the column down until it rest on its shims or the concrete.

9. Install all the anchor bolt buts with washers and tighten down using a 4’ level as a guide to set the

column plumb.

10. An impact with deep sockets can speed up this process.

11. Once all the bolts are tight, slowly let off the load on the rigging and watch that the column is

secure and does not start to lean.

12. Send up a man in a lift or ladder to disconnect the rigging. It is good practice to give the column

hung up on the anchor bolts and not be on the a firm base with all the cuts fight.

13. If possible install girts and flange braces as soon as possible.



CONNECTING PRIMARY STEEL COMPONENTS

General:

Prior to starting bolting operations a job site hazard assessment must be done to ensure that any job site

specific hazards are addressed with special considerations given to the following.

Working around the lifting equipment

Access to the connections

Equipment to use for access

The height at which the connection is to be made.

The ground conditions and grades is man lifts are to be used.

The location of other workers on site

The plan to eliminate job site traffic from connection area.

Hazards present

Sharp edges

Pinch points

Crushing

Working at heights

Working with cranes

Working off ladders


Working with fall protection systems

Rigging removal

Personal Protective Equipment (PPE) required:

Leather gloves


Full body harness with 6` lanyard

Eye wear

Hardhat

Training required






Procedure:

1. Complete a hazard assessment form.

2. If using man lifting to connect out of, complete a lift inspection form on all equipment that will be

used. If using ladders inspect ladder and ensure you have a means to tie it off to the column

example; rope or clamps.

3. Dress for the weather conditions of the day.

4. Inspect and done fall protection harness with lanyard.

5. Gather up all tools needed to safely make connections and either put them in a tool belt or in the

man lift you have been assigned making sure that all tools are secure in the lift and cannot fall out

and cause an incident.

6. Get the proper bolts needed for the connection making sure to have the right size and length

required, ask the foreman if you are not sure.

7. Stay in your lifts or at the bottom of the ladders, keeping out of the way of the lift until you are

directed by your foreman to go to the connection site. He will get you to do so after the lift has

been deemed safe and its nearing the time for you to make the connection. It is good practice to

try and stay out from under a lift for as long as possible.

8. Position your lift at the connection in a way that least blocks the view of the lifting equipment

operator, not be under the lift and also does not require you to need to stand on the rails of the

man lift. If working off a ladder, be sure to tie off the base of the ladder before going up to the

connection. Once there, tie off the column before working on the connection.

9. Help guide the incoming piece of steel and position the bolt holes so the connection is in the use

erection wrenches or bars to help line up the bolt holes.

10. Install all the bolts in the connection. Wrench tightening at least 2 kiddy corner bolts.

11. If asked to do so by the foreman be prepared to impact (tighten) all the bolts in the connection.

12. If asked to by the foreman, help install any temporary bracing that is necessary.

13. When told to, help disconnect the rigging that was used to hoist the beam and safety remove it

(dropping it to the ground only as a last resort, with the foreman`s permission and after the area

has been checked for people and or equipment that could get hurt or damaged.)

14. Come back down to the ground and prepare for the next connection.



INSTALLING ROOF SECONDARY General:

Prior to starting roof secondary installation a job site hazard assessment must be done to ensure that any

job site specific hazards are addressed with special considerations given to the following:

Equipment to be used to hand bundles of secondary

Equipment to be used to disconnect the rigging

The height at which the rigging will end up

The ground conditions for the crane or forklift

Rigging to be used including softeners.

The fall protection system to be used on this steal.

Hazards present

Sharp edges

Pinch points

Crushing

Working at heights

Working with cranes


Rigging


Personal Protection Equipment (PPE) required:

Leather gloves


Fully body harness with 6` lanyard

Eye protection

Hardhat

Training required: Note: Varies with task being performed during lift but could include.




Crane signal training

Basic rigging training





Procedure:

1. Complete a hazard assessment form and discuss with workers prior to commencing work

2. Ensure that the rafter safety system is installed and that it is installed properly.

3. If using a cane set it up as close as possible to the bay being erected. Be sure that if is set up on

good stable ground.

4. If using a forklift be sure that the ground is level to allow for the turning that is necessary to land

the bundles of purlins.

5. Always break the bundles up into weights that are not doing to stress the lifting equipment.

6. Try to hand the bundles as close to the columns as possible.

7. The preferred system of rigging is to use 2 wire rope slings of an acceptable capacity spaced

about 6 feet apart centered on the loads with a rope tied to one of the slings. Through the other

and then laid out to one end of the bundle and tied off.

8. It is best that the purlins team both be up on the rafter`s one on each of the rafters that the

purlins are to be connected to.

9. After landing the purlins the erector that is on the rope side can pull o the rope to bring the slings

over to his side with the assistance of the lift equipment and then remove the rigging and

carefully drop it to the ground.

10. The purlin team can then break the bundle apart and start putting them in place by walking them

down the rafter`s one at a time.

11. It is preferred to install start at the bottom of the rafter and work their way to the top but in

some situations it might be preferred to install some stut purlins in various locations to add to the

strength of the building during erection.

12. At all times the key is to work as a team.

13. The erector on the lap side or side that already has purlins installed on the adjacent bay should

make his connection first and should install 2 bolts into the rafter.

14. Then the erector on the other side can make his bolt and should only install one and it can be

hand tight unless situations like high winds or it being the last bay of the day in which case it

should be tightened.

15. This is repeated until the bay is completed



HEAVY TRUSS LIFTING General:

Prior to starting lifting operations a job site hazard assess must be done to ensure that any job site

specific hazards are addressed with special considerations given to the following:

Equipment to be used to lift truss

Access to the truss connections

Equipment to be used for access

The height at which the connections are to be made

The ground conditions for the cranes

The location of other workers onsite

The plan to eliminate job site traffic from connection area

Rigging plan and condition of the slings

The communication system to be used for the lift

Operator training

Hazard present:

Sharp edges

Pinch points

Crushing

Working at heights

Working with cranes

Working off of man lifts


Rigging


Personal protective equipment (PPE) Required:

Leather gloves


Fully body harness within 6` lanyard

Eye-protection

Hardhat

Training required Note: varies with task being performed during lift but could include:










Procedure:

1. Complete hazard assessment and discuss with workers prior to commencing work

2. Complete a lifting pan that includes: the cranes to be used, the location of the cranes, the rigging

plan and the position and task of each man on the crew.

3. If using man lift to connect out of, complete an aerial lift inspection. If using ladders inspect ladder

and ensure you have a means to tie off the column i.e. rope or clamps

4. Complete critical lift checklist and have it signed off by the foreman in charge.

5. Have a pre-lift meeting with all people involves to review the lift plan

6. Set up the crane or cranes in the location(s) that have been laid out in the lift plan

7. Rig up the truss with the rigging that was specified in the lift plan and the check list.

8. Attach tag lines as needed but as least 2 as a minimum

9. Designate only one signalman BUT ANYONE ON THE CREW CAN SIGNAL STOP.

10. Use radios to communicate during a lift.

11. Keep all personnel that are not required in the lifting operations away from the area.

12. Flag off the whole danger area with danger tape and or barricades.

13. Get the connectors ready with the right bolts and tools and keep them out of the way.

14. When the area and personnel are ready to lift, the supervisor will commence the lift, lifting the truss

off the ground a few feet and stopped to recheck all the rigging and cranes.

15. The lift supervisor will continue with the lift only after they have ensured that everyone is clean of

the area again.

16. Once the lift is approached its final position the connectors can start to go up to their connections,

trying to stay out from under the load wherever possible.

17. With the help of the connectors, the lift supervisor will guide the crane operator(S) in positioning the

truss up against or onto the tops of the columns.

18. The lowest connection point on the truss is the one that is connected first followed by the next

lowest and so on, so the crane(s) are putting the truss down and not lifting up up to make the

connections.

19. Note: if the truss is level enough then two or more connections can be made at once.

20. After all the connections are made and all the bolts are installed (and impacted if required) than any

temporary bracing that is required can be installed by the connectors and the swamper. An engineer

should design this bracing.

21. After the foreman has double-checked the connections and the bracing, they will then give the lift

supervisor permission to lower the load slowly. It is good practice to have one to two connectors

watching the truss as the load is transferred off the crane and to the columns, watching for any signs

of things going wrong.

22. After the load has been completely transferred and the rigging is slack, the connectors can remove

the rigging and safely return it to the ground. Only as a last resort will the connectors let the rigging

fall to the ground and only after they have permission from the foreman and the area below has

been cleared of personnel and equipment.

23. Always recheck all rigging at end of each lift before using it again.



BAY LIFTING General:

Prior to starting lifting operations, a job site hazard assessment must be done to ensure that any job site-

specific hazards are addressed with special consideration given to the following:

Equipment to be used to lift the bay

Access to the connections

Equipment to be used for access

The height at which the connections are to be made

The ground conditions for the cranes

2. Complete a lifting plan that includes. The cranes to be used, the location of the cranes, the rigging

plan and the position and task of each man on the crew.

3. If using man lifts to connect out. Complete man lift inspection. If using ladders inspect ladder and

ensure you have a means to lie off to the column i.e. rope or clamps.

4. Complete critical lift checklist and have it signed off by the foreman in charge.

5. Have a pre-lift meeting with all people involved to review the lift plan, discuss all points on the

hazard assessment form and answer any questions that may arise.

6. Set up the crane or cranes in the location(s) that have been laid out in the lift plan.

7. Rig up the bay with the rigging that was specified in the lift plan and the checklist.

8. Attach tag lines as needed but at least 2 as minimum.

9. Designate only one signalman BUT ANYONE ON THE CREW CAN SIGNAL STOP.

10. Use radios to communicate during the lift.

11. Keep all personnel that are not required in the lifting operations away from the area.

12. Flag off the danger tape and or barricade the entire lift area

13. Get the connectors ready with the right bolts and tools and keep them out of the way.

14. When the area and personnel are ready, the lift supervisor will commence the lift. Lifting the bay off

the ground a few feet and stopped to recheck all the rigging and cranes.

15. The lift supervisor will continue with the lift only after he has ensured that everyone is clear of the

area again.

16. Once the lift is approached its final position the connectors can start to go up to their connection

sites, trying to stay out from under the load wherever possible.

17. With the help of the connectors the lift supervisor will guide the crane operator(s) in positioning the

bay up against or onto the tops of the columns

18. The lowest connection point in the bay is the one that is connected first followed by the next lowest

and so on, so the crane(s) are putting the bay down and not lifting it up to make the connections.

19. After all four connections are made and all the bolts are installed (and impacted if required) than any

temporary bracing that is required can be installed by the connectors and the swamper. On small

lifts, the foreman can make the call for bracing but on a larger more complex lift, an engineer should

be consulted.

20. After the foreman has double-checked the connections and the bracing, they will then give the lift

supervisor permission to lower the load slowly. It is good practice to have one or two connectors

looking at the bay as the load is transferred off the crane and onto the columns, watching for any

signs of things going wrong.



ERECTING INSULATED WALL PANELS

GENERAL

Prior to starting lifting operations a job site hazard assessment must be done to ensure that any job site

specific hazards are addressed with special considerations given to the following

Equipment to be used to lift the panels

Equipment to be used to disconnect the rigging

The height at which the rigging will end up

The ground condition for the crane or forklift

Rigging to be used including proper size of panels clamp

The pick-up radios and swing potential of the wall sheet.

Hazards Present

Sharp edges

Pinch points

Crushing

Working at heights

Working with crane/forklift


Rigging


PPE Required

Leather gloves

Coveralls



Sunglasses on bright days

Hard hat

Training Required- Note varies with task being performed during lift but could include


Man lift training


Crane operating training




Procedures

1. Complete hazard assessment

2. Know the weight of the wall sheet to be erected and be sure it is within the capacity of lifting

equipment.

3. Use appropriate rigging. Make sure the sling used to attach the lifting clamp to the lifting equipment

is of an appropriate size and in good condition. Also, make sure the lifting clamp is the right size to

snugly fit on the top of the wall panel. Make sure that the panel clamp fasteners (3 screws) are

installed in the clamp securing the wall panel clamp.

***Clamp screw installation must be verified by 2 people prior to the lift signal being given or

verified by the machine operator***

4. If using a crane set it up as close to the wall panel and its final location as possible. This is to reduce

the length of boom needed as lifting wall panels can side load a boom very fast. This can be

extremely dangerous. Be sure to allow room for a man lift to be able to disconnect the rigging. Is

using a forklift try to limit the distance you will travel to as short as possible.

5. If lifting with a forklift drive the lift in a direction that reduces any side loading of the boom and be

sure to get the hook over the center of the wall panel before lifting it off the ground to prevent the

panel’s base from swing out.

6. If limiting with a crane the same ideas applies, be sure to swing with the wall panel as it comes off

the ground and try to keep the ball over the top of the wall panel and level. Never allow workers to

be under the load.

7. Once the wall panels comes off the ground keep it low and have a swamper hold the bottom as the

lifter positions the panel. Never allow the swamper to stand under the load only beside it.

8. When properly positioned slowly let the wall panel down until it rests on its base angle or the

concrete

9. Use a lever against a clamp that is attached to the girt to slide the wall sheets together

10. Once you have a nice lap check the panel for plumb and make any small adjustments.

11. Fasten the panel to the girts with the appropriate fasteners and clips.

12. Disconnect the clamp and hold the panel tight to the girts.

13. Note: it helps to speed up the process if you have two panel clamps so that one can be prepared

while one is being lifted.

HOT WORK PERMIT

General

Hot work operations include tasks such as welding, brazing, torch cutting, grinding and torch soldering.

These operations create heat. Sparks and hot slag that have the potential to ignite flammable and

combustible material in the area surrounding hot work activities

Procedure

1. Before conducting any HOT WORK, the operator shall determine if there is a safer way to doing the

work without the use of any heat or flame-producing device.

2. Prior to conducting HOT WORK, the operator must contact their direct supervisor indicating the

scope of work and the location where the work is to be performed.

3. The operator must check to see that all aspects of the proposed work meets all safety measures as

indicated on the HOT WORK PERMIT.

4. The worker must complete, sign and post the HOT WORK PERMIT in plain view. These permits should

be posted in designated hot work permit pockets.

5. The worker or designated must conduct a fire watch during the work (lunch and breaks) and for 30

minutes after the work is completed. The worker who is conducting the fire watch shall have a fire

extinguisher readily available and trained in its use.

Fire watch is required when:

a) Combustible material in construction or contents is closer than 35 feet to the point of operation.

b) Combustibles are more than 35 feet away but are easily ignited by spark

c) Wall or floor openings with 35 feet expose combustible materials in adjacent areas including

concealed spaces in walls or floors

d) Combustible materials are adjacent to the opposite side of metal partitions, walls, ceilings, or

roofs and are likely to be ignited by head conduction radiation.

6. The worker must provide the HOT WORK PERMITS to the supervisor or safety when finished.



What is the process for obtaining a HOT WORK PERMIT?

A HOT WORK Operator determines a need for hot work.

The HOT WORK Operator ensures the area around hot work activities complies with the safety requirements of the HOT WORK PERMIT.

The hot work Operation inspects the hot work site and completes the

HOT WORK PERMIT Form

The HOT WORK Operator posts a FIRE WATCH if the situation requires one.

Once all permit safety guidelines are satisfied, the Hot Work Operation signs and posts the permit

The Hot Work Operation can then begin hot work.
