SECTION 14
SITE SAFETY PROCEDURES
PRE-JOB SAFETY PLANNING
1. Purpose
To establish guidelines to determine what special safety precautions are required for a particular project.
Planning safety into a project is just as important as setting production schedules and planning for the delivery of equipment and material. Failure to do so may result in costly work slowdowns or stoppages due to serious accidents, injuries or citations from regulatory agencies.
In order to plan safety into a project, certain information must be obtained and analyzed in advance.
The following is a list of things to consider prior to mobilizing a project.
Does the scope of work involve any unusual or high-risk work?
Are there any special work permitting requirements?
Is there any work involving the handling of hazardous materials?
Will there be any cranes, hoists or lifting devices on site?
Are there heavy, unusual or critical lifts to be made? Who will plan these lifts?
What personal protective equipment is required?
Are there any special scaffolding requirements?
Are evacuation procedures required?
EMERGENCY ACTION PLAN
1. Purpose
To provide superintendents with an established set of guidelines for the monitoring of severe weather, securing the jobsite in advance of severe weather and the evacuation of the jobsite in the event of fire, bomb threat, chemical release and other types of emergency situations.
2. Responsibility
It is the responsibility of the superintendent to review these guidelines with his/her employees and to complete the “Emergency Action Plan” form. He shall document the review of this procedure on the training form, provided elsewhere in this manual, and post the “Emergency Action Plan” with the required mandatory posters.
3. Weather Monitoring
The jobsite shall be provided with a weather alert radio. This radio should be placed where it can be monitored throughout the day, i.e. with the secretary or in the tool room. When the weather service issues watches or warnings for your area, the individual monitoring the radio shall notify the superintendent or safety coordinator. The following action will be taken:
Watches

PERMITS
1. Purpose
To provide a procedure, which will establish the practices, required to minimize injury and provide for safe working conditions when there is an absence of owner provided permits.
In the event the owner does not have a formal procedure for Lock Out/Tag Out, Equipment Work-Hot Work-Line Entry Permit or Confined Space procedures, the above mentioned permits, found at the end of this section, shall be used.
2. Equipment
Entry
Prior to beginning any work, the superintendent or his designee shall review the conditions in and around the work to determine if and when permitting is required.
It shall also be determined if there are any particular products expected to be encountered and what cleaning is required. At which time the superintendent or his designee shall review the Material Safety Data Sheets and inform the employees responsible for the work of the hazards and precautions needed. The superintendent or his designee shall implement the "Lockout, Tagout" procedure at the time specified by the owner. He shall then complete the appropriate permits.
3. Line
Entry
Prior to beginning any work, the superintendent or his designee shall review the piping system with the owner to determine isolation points, outage requirements and cleaning of the system. This shall be done as early as possible to permit scheduling of the outage.
The Material Safety Data Sheets (MSDS) shall be reviewed for the particular product expected to be encountered to determine the related hazards. He shall inform those employees responsible for the work of the hazards and precautions needed.
Face shields, goggles and gloves are required as a minimum when opening any line. Additional protection may be required per the MSDS.
The superintendent or his designee shall implement the "Lockout, Tagout" procedure at the time specified by the owner. He shall then complete the appropriate permits.
Where hot work is required, or when hazardous materials may be encountered, after the
“Lockout, Tagout” procedure has been implemented, slip blinds shall be installed in the first flange joint on either side of the area to be entered or modified. In the absence of flanges, expandable rings shall be used.
At all entry points, including those for slip blind installations, the ground shall be protected to prevent soil contamination or control the spillage within the building.
Unbolting of flanges:
Always work above or behind the flange joint where possible.
Loosen the bolt the furthest away from you and the bottom studs before the top as follows: the furthest away; 3 full turns, the lower bolts; 2 full turns and break the seal away from you. This will minimize the chance of injury.
If the line is found to have pressure, retighten the bolts closest to you and proceed to tighten the joint. Then contact the Superintendent or Foreman.
When entering a welded system where the pressure or drainage cannot be verified, a pilot or inspection hole shall be drilled at the entry point. This hole shall be no larger than 1/4".
When drilling the inspection hole, the drill bit shall be cooled with water.
If the line is found to be under pressure, the area shall be cleared and the owner and superintendent notified.
Where practical, all initial cutting shall be done with port-a-bands.

LOCKOUT, TAGOUT PROCEDURE
1.
Purpose
The intent of this procedure is to establish minimum guidelines for isolation, securing and clearing of equipment and piping to allow personnel to safely perform the required maintenance or modification.
2. Responsibility
It is the responsibility of the site superintendent or his designee to ensure the implementation of the procedure and responsibility of the safety director for the training and documentation necessary to carry out this procedure.
3. Definitions
Authorized Person: A person who implements a lockout or tagout procedure on equipment and or piping to perform servicing or modifications.
Affected Person: An employee whose job it is to use, operate or be in the area of a machine or pipe on which service, or modification is being performed under lockout conditions.
Clear: Action taken to clear personnel from equipment or piping during the "trying" step to ensure that no injury or equipment damage will occur if this equipment or piping is energized.
Designated Employee: A knowledgeable employee designated by management to conduct lockouts.
Energy Isolation: The disconnection or isolating of piping or equipment and the bleeding of stored energy or pressure.
Energy Isolation Device: Include, but not limited to valves, fuses, circuit breakers, disconnect switches, plugs, or flanges.
Equipment: Any tool, machine, piping, vessel, or wire(s).
Lockout: A sturdy padlock having no duplicate keys on site. Duplicate keys shall be tagged with the project name and given to the safety coordinator.
Locking Devices: Any accessory, which involves the alignment of two holes, that when secured with a lock prevents the switching or changing position of an energy isolation device.
Point of Operation: The area of piping and or equipment where the actual work takes place.
Release: Authorization given to those individuals to work on deactivated equipment.
Secure: Performing this procedure on a lockout point.
Stored Energy: Residual or available energy including but not limited to electrical, hydraulic, pneumatic, chemical, thermal, or mechanical energy.
Try: Verification that the equipment has been properly deactivated or isolated.
4. Deactivation
and/or Isolation
Once it has been determined that a piece of equipment needs to be locked out for service, modification, line entry, or guard removal, the authorized person shall be notified for lockout.
The authorized person shall inform the owner’s representative of the need to shut down and lockout the required piece of equipment.
The authorized person shall review the equipment or system to determine the energy isolation point(s) and that the possibility of stored energy can be eliminated. If there is any doubt concerning this review, he shall review the situation with the owner’s representative.
He shall then begin the shutting down of the equipment or system in an orderly manner. As the system is being isolated, he shall lockout each point of energy isolation, using a tagged locking device and lock.
· If a lock or locking device cannot be installed, a tag may be used in lieu of a lock, providing at least one additional safety measure that provides the safety equivalent of a lock is in place. These may include but are not limited to removal of fuses, opening of additional switches, etc.
Once ALL points of energy isolation have been locked-out, the authorized person shall then begin bleeding the stored energy or pressure. This may be done through the use of flanges, vents, drains, equipment brakes, lowering loads or counter balances, release of springs, etc.
After all energy isolations have been done and locking devices installed, the authorized person shall then clear the equipment and then try to engage those items which have been locked out to ensure that the equipment cannot start or energize.
· Situations may exist when an effective try cannot be made to lock out a piece of equipment because of interlocks in the circuits. In these cases, the authorized person shall contact the Owner for assistance.
Once the equipment has been isolated and locked out the authorized person shall notify the affected personnel that they can now place their lock on the locking device.
Prior to the affected person(s) attaching their lock, to the locking device, he shall ensure to himself that the isolation points are in the deactivated or closed positions and verify that the equipment is secured. The affected employee shall keep his key for his lock as long as the lock is in use.
5. Lockouts
Continuing Through Shift Changes
All individuals leaving work for the day shall review all lockouts at energy isolation points, hazards which may exist, and the status of the job with both the on coming supervisor and affected craftsman prior to removal of his lock.
If no hazard exists, the affected employee shall remove his lock and tag before he leaves the plant.
If a hazard to personnel or equipment would exist by removal of the lock(s) the on-coming craft shall install his lock(s) at all energy isolation points, then clear the equipment and try to energize equipment before beginning work. If there is no shift change, the authorized person shall notify the Owner that the lockout will remain on the equipment.
6. Lockout
Removal and Re-Energization of Equipment
The following requirements shall be met in order, before equipment is energized, even temporarily.
The authorized person shall conduct inspections as necessary, to verify that all tools, jumpers, blocks and similar devices have been removed so that the equipment can be safely energized or pressurized.
Affected employees that may be exposed to the energizing of the equipment shall be warned to stay clear of the equipment.
Each lock and tag shall be removed by the individual who applied it or by the authorized person under his direct supervision.
In the event an affected employee is absent or an unidentified lock is found on a lockout device, a qualified person may remove his lock, after a lock removal permit (Attachment 2) is filled out.
· The supervisor is sure that the individual is not on site.
· That reasonable efforts to contact the individual have been made.
· That when the individual returns to work, he be notified immediately that his lock was removed and the status of the equipment before be begins work in the area. A copy of the lock removal permit shall be given to the employee, a copy put in his personnel file, and one given to the Corporate Safety Director.
After all locks are removed, the

The Entry Supervisor shall then conduct a "Pre-Entry" meeting with all participants. He shall then review the work to be performed, all the hazards of the space including the TLV, TWA, PEL, Ceiling and Max peak, using the MSDS (when required), any tests that will be conducted, and all the equipment required. All training shall be documented on the training sheet. A copy shall be filed in the entrant's file, one attached to the permit, and the original sent to the Safety Coordinator at the Memphis office.
If it has been determined that piping or equipment needs isolated, it shall be performed at this time per SMC's Lockout, Tagout Procedure.
All necessary equipment shall be taken to the confined space. This includes all lighting PPE and rescue equipment.
A copy of the permit, training sheet and applicable MSDS shall be posted at the entrance to the space.
When all is ready, the guard rails and/or barricades shall be set up, to keep unauthorized persons from entering the area and to protect the entrants.
The entrance shall be opened and the space tested to determine if acceptable entry conditions exist. Testing shall be performed to OSHA standards and will be done as follows:
a. Oxygen Levels
b. Flammable/combustible gases present
c. Toxic Contaminants
d. Others (as noted)
Upon satisfactory test results, the Entry Supervisor shall sign the permit allowing entry to the space.
If unsatisfactory conditions are found, they shall be corrected before the permit is signed.
All entrants shall put on all necessary personal protective equipment, rescue harnesses, etc.
Entry can now begin.

SUSPENDED WORK BASKET
1. Purpose
To establish guidelines for the safe set up and use of suspended work baskets on construction sites.
2. Responsibility
The safety coordinator shall be responsible for the implementation of this procedure. The superintendent shall be responsible for the compliance to this procedure.
3. General
The use of a suspended work basket is prohibited unless when the erection, use or dismantling of conventional means such as ladders, scaffolds, aerial lifts, etc. would be more hazardous or is not possible due to structural design or site conditions. Cost(s) shall not be considered.
Crane(s)
1. The crane shall be set up and leveled within 1% (1 foot in 100 feet).
2. Cranes equipped with outriggers shall have them fully deployed in accordance with the operations manual when performing trial lifts and lifting personnel.
3. Cranes equipped with live booms shall not be used.
4. The crane shall be equipped with an operating anti-two block device.
5. Load drums and boom hoist drum brakes, swing brakes (where applicable) shall be engaged when the work basket is in a stationary position.
6. Prior to performing any trial lift or personnel lift, the crane shall be inspected by a qualified individual. Inspection shall include the sheaves, wire ropes, brakes, outriggers (where applicable), pins, and hoses. This shall be documented in the crane inspection log.
Rigging
1. Rigging used for the suspension of the work basket shall not be used for anything else.
2. The hook on the crane shall be equipped with a positive safety latch. Once the rigging has been attached, the latch shall be pinned to prevent the latch from accidentally opening.
3. Prior to each use of the rigging, it shall be inspected by a competent individual. Any damaged item found shall be replaced before continuing with the trial lift or personnel lift.
Work Basket
1. Only work baskets designed by a structural engineer and fabricated by certified welders shall be used.
2. The work basket shall not be loaded beyond its capacity. (Note: workmen shall be estimated at 250 pounds each.)
3. Only those employees required to perform the work shall be permitted in the basket.
4. Secure all material in the basket to prevent movement while being raised or lowered.
5. The work basket shall not be used as a material or tool hoist.
4. Operations
Once it has been determined that work must be performed from a work basket, the superintendent shall conduct a pre-lift meeting to discuss the work and to review this procedure. The crane operator, flagman (if required) and workers directly involved shall attend.
The pre-lift meeting shall be repeated when additional or new employees are assigned to the operation or when the crane is set up at a new location.
The crane shall be brought to the work area and set up per the manufacturer's instructions and this procedure.
Once in position, the work basket shall be attached to the crane, and lifted to position to ensure the lift can be safely made. Obtain the data required for the work basket permit.
After obtaining the necessary information for the permit, the work basket shall be returned to the ground and loaded to 1.25 times the rated capacity for the trial lift.
The suspension rigging shall be inspected and verified that it is properly attached to the crane. Any portion of the rigging found to be defective shall be replaced before the trial lift. The crane shall be inspected at the time as outlined above.
The crane shall lift the work basket to approximately 3'-0 off the ground and hold it in that position for a minimum of 5 minutes. All brakes shall be secured.
After holding in position for 5 minutes, the man basket shall be lifted and swung to the point where it will be when work is being performed.
The crane will then return the basket to the staging area where all the test weights shall be removed.
The work basket, rigging, crane and ground shall be inspected for any visible defects which may cause an unsafe condition.
All defects shall be corrected and the entire trial lift shall be repeated.
If the crane has to be moved in order to complete the work, a new pre-lift meeting, permit and trial lift must be done prior to employees working from the basket.
If the crane must travel to place employees at a work site, a trial run with test weights shall be made at the same time as the trial lift.
If the crane is equipped with pneumatic tires, the tire pressure shall be checked. The pressure shall be per the manufacturer's recommendations.
Travel shall be limited to a solid, level, restricted runway. Limit of travel is restricted to the radius of the boom. The boom shall be parallel to the direction of travel.
5. Work
Practice
While employees are in the work basket, the operator shall remain in the crane.
Upon entering the basket, the employees shall secure themselves to the man basket using body harnesses and lanyards.
Employees shall keep all body parts inside the basket, except for performing their required task(s). Employees shall not "rock" the basket.
If an employee must exit the basket while it is suspended, the basket shall be secured to the structure before they exit, unless securing to the structure creates an unsafe condition.
If employees perform work out of sight of the operator, a competent flagman shall be positioned where he can see both the employees and the crane operator. If placing a flagman is impractical, two way radios shall be used. They shall have a clear channel with no other communication on it.

EXCAVATION
1. Purpose
To establish guidelines for all phases of excavation work which includes, but not limited to, preliminary, access, spoils, personnel protection and inspection.
2. Responsibility
It is the superintendent’s
responsibility to comply with this procedure.
He shall ensure that the civil foremen have read this procedure and are
knowledgeable of these requirements.
The superintendent shall inspect the excavation prior to allowing
employees to perform any work in the excavation.
3. Definitions
a. Cave In Separation of a mass of earth/rock from the side of an excavation from under a shield or shoring in sufficient quantities that could trap/bury or injure a person.
b. Cross Brace A horizontal member perpendicular to the excavation on which its ends bear against uprights or walls.
c. Excavation Any manmade cut, trench, depression, etc., made in the earth's surface, formed by earth removal.
d. Face or Side The vertical or inclined earth surfaces formed due to or as a result of excavation work.
e. Failure Breakage, displacement or permanent deformation of a structural member or connection such that is structural/support/integrity has been compromised.
f. Kickout The accidental release or failure of a cross brace.
g. Walers Horizontal member of a shoring system placed parallel to the face, whose sides bear against vertical members of the shoring or earth.
4. General Requirements
a. Utilities
1. Prior to any digging, the excavation area shall be reviewed with the Owner, utility companies, etc., to determine if there are any underground installations (telephone, water lines, gas lines, high water tables, soil conditions, etc.)
2. Utilities shall be notified 48 hours prior to excavation.
3. When excavations approach the approximate area of an underground installation, the exact location of the installation shall be determined by safe means (hand digging, devining rods, probes, etc.).
4. When the excavation has exposed underground installations, they shall be protected, supported, or removed as necessary to protect employees.
b. Access
1. Structural ramps used solely by employees shall be designed by a competent person. Ramps used for equipment shall be designed by a competent person qualified in structural design.
2. Ramps constructed of two or more members shall be of uniform thickness and shall be secured to prevent movement.
3. Cross members used in ramp construction shall be attached to the bottom. Ramps used in lieu of stairs or ladders shall have cleats attached on the top to prevent slipping.
4. Ramps, ladders or stairways are required in any excavation of 4 feet or deeper for employee access. They shall be spaced at intervals no more than 25 feet for the entire length of the excavation.
c. Water Control
1. No employee shall work in excavations where there is accumulated water or accumulating water unless precautions have been taken to protect employees. The precautions may vary, but could include engineered shoring, life lines, safety harnesses, etc.
2. Should excavations interrupt natural drainage (i.e. streams, creeks, etc.), diversionary ditches shall be constructed to divert waters from entering the excavation.
d. Adjacent Structures
1. When excavations affect the stability of buildings, walls, etc., or if the excavation(s) undermines any foundation, a support system shall be designed by a professional engineer and installed in accordance with the drawing(s), or the engineer determines that such excavation work will not pose a hazard to employees.
2. Sidewalks, driveways, roadways, foundations, etc., shall not be undermined unless the employees are protected against the collapse of the structure.
e. Traffic
1. Employees exposed to public traffic shall wear a warning vest of a highly visible material.
2. When mobile equipment is required to operate near an excavation and the operator's view is obstructed, a barricade system shall be used.
3. All earth moving equipment shall be equipped with a back-up alarm.
f. Spoils/Materials
1. Spoils and/or materials shall be stored no closer than 2 feet from the edge of the excavation. Additional barricades may be required to prevent materials from falling or rolling into the excavation.
g. Fall Protection
1. Where employees or equipment are required to cross over excavations, walkways or bridges shall be constructed. They shall be capable of withstanding twice the intended load and shall be equipped with standard guardians and toe boards.
2. All excavations shall be guarded by standard guard rail systems. Upon completion of all exploration, wells, pits, caissons shall be back filled.
5. Soils Classification
Soils classification applies when sloping/benching or shoring is required to protect employees in excavations from cave ins.
Definitions:
a. Cemented Soil A soil held in place with chemicals such as calcium chloride, grout, etc.
b. Cohesive Soil Clay or soil with a high clay content. Cohesive soil can be excavated with vertical side slopes. It is hard to break when dry.
c. Dry Soil Soil that shows no visible signs of moisture.
d. Fissured Soil Soils with open cracks and cracks with little resistance. It also has a tendency to break along the cracks easily.
e. Granular Soils Soils such as gravel, sand or silt, which have little or no clay content. Granular soil cannot be molded when moist and crumbles easily when dry.
Note: Classification of soils may change due to site or weather conditions, therefore protection systems may also change.
f. Layered Soil Two or more distinctly different soils arranged in layers.
g. Moist Soil Soil that looks and feels damp. This soil can be molded into a ball and rolled into fine threads before crumbling.
h. Saturated Soil Soil with voids filled with water. It does not require flow.
i. Type A Soil Cemented or cohesive soils, but not if the soil is fissured. If the soil has been disturbed or is subject to heavy vibrations such as road traffic, pile driving etc., or layered soils greater than 4H:1V.
j. Type B Soil Soils such as silt, loam, sandy loam, silty clay loam or sandy clay loam, and previously disturbed soils or fissured or disturbed Class A Soil. This also includes dry, unstable rock or layered soils less than 4H:1V.
k. Type C Soil Soils which include gravel, sand, loamy sand, submerged soil, or soil from which water is freely seeping.
6. Testing Soils for Classification
a. Visual Examination
1. Area
Inspect the area around the excavation for utilities or other underground structures. These indicate the soil has been disturbed. Check the area for surface water, sources of vibrations that may affect the excavation face.
2. Spoils
Examine the soil as it is excavated. Soils comprised mainly of fine grain material are cohesive. Soils comprised mainly of sand or gravel are granular. Soils remaining in clumps are cohesive. Soil that breaks up and does not stay in clumps is granular.
3. Excavation
Inspect the surface area and sides of the excavation crack like openings, chunks falling off a vertical side, spaces are evidence of fissured material and moving ground. These are potentially hazardous. Check for evidence of seeping water from the sides and check the side to estimate the slope of layered material (if present).
b. Manual Testing
1. Use a pocket penetrometer or a hand held shearvane.
2. Attempt to roll soil into a ball and into threads of 1/8" diameter. Cohesive soils can be rolled without crumbling.
7. Personnel Protection
a. Air - The atmosphere of excavations greater than 4 feet deep, those in the vicinity of landfills, where hazardous materials are stored, or where there is the potential for hazardous atmospheres, shall be measured. The oxygen level must be 19.5% or greater.
b. Protection Systems - Are not required if the excavation is :
1. In solid rock
2. Is less than 5'-0" and a competent person determines there is no chance of a cave in.
Protection systems are required for excavation depths of 5'-0" to 20'-0". Depths greater than 20' require a system designed by a professional engineer. Protection systems include reposing or sloping of the sides, benching or steeping the sides, shoring using lumber or manufactured systems, and trench shields.
See attached sheets for acceptable means of protection for depths to 20'.
Note: There are 2 tables for each soil Type A, B and C. Using material shown on either sheet will produce the same strength. Mixing of material from each table per soil type is not allowed.
c. Rescue equipment (i.e., harness, stretcher) is required where it is evident that hazardous situations are probable.
8. Shoring/Support Installation and Removal
a. Members of support systems shall be connected together to prevent sliding, falling, kickouts, or other predicted failures.
b. They shall be installed and removed in such a manner as to prevent cave in, structure collapse, or from being struck by members.
c. Before temporary removal of individual members begins, precautions shall be taken to ensure the safety of the employees.
d. Removal shall begin at the bottom of the excavation. Members shall be released slowly to note any indication of a possible failure of the remaining members or cave ins.
9. Sloping/Benching
No personnel shall be permitted to work on the sloping surface or bench level above personnel.
10. Shield Systems
a. Shields shall be installed in a manner to prevent lateral loading.
b. Employees shall be protected from cave ins when entering shields.
c. Employees shall not be permitted in shields when they are being moved.
11. Inspections
a. Inspections shall be done every day by a competent person for evidence of situation(s) that may produce cave ins, failure of a protection system or other hazards. The inspection shall be done prior to beginning of work and as required throughout the shift.
b. If conditions indicate the possibility of a cave in, system failure or hazardous atmosphere, all employees shall be removed until the hazard(s) have been corrected.

100 % FALL PROTECTION
Purpose
The purpose of this procedure is to
provide 100% fall protection program to
our employees.
Responsibility
It is the responsibility of the
site superintendent or his designee to ensure the implementation of the
procedure and responsibility of the safety director for the training and
documentation necessary to carry out this procedure.
General Requirements
·
Primary fall protection systems are the preferred
methods of fall protection and exhaustive efforts shall be taken to use them
before resorting to secondary fall protection systems.
·
In order that fall protection is available to employees
at all times, they shall wear an approved full body harness with two
shock-absorbing lanyards (secondary fall protection) when six feet or more
above their work surface or when it can be reasonably anticipated that movement
beyond that work surface will be required.
Primary Fall
Protection Systems
·
Primary fall protection systems provide walking and
working surfaces in elevated areas which are free from floor openings, are
equipped with standard guard rail systems on all open sides and with closure
apparatus for ladder openings, or other points of access, when required. These
systems include but are not limited to scaffolds, aerial lifts and other
approved personnel lifting devices.
·
Standard guard rail systems consist of a top rail
approximately 42 inches above the walking/working surface, a mid-rail at
approximately 21 inches above that surface and a four inch tall toe-board at
the working surface. Upright support post spacing shall not exceed eight feet,
and the entire system must be capable of supporting 200 pounds force in any
direction with minimum deflection.
·
Floor opening/hole covers are used to close openings
and holes in floors, platforms and walkways. These covers shall be capable of
supporting the maximum potential load they may be subjected to, shall
completely cover the opening/hole and be secured against accidental
displacement. Covers shall be marked “HOLE COVER - DO NOT REMOVE”.
·
Aerial lifts and other vehicle mounted elevated work
platforms shall be used in accordance with 29CFR 1926.556, “Aerial lifts” , and
ANSI A92.2. Forklifts with appropriately designed personnel platforms shall
comply with 29 CFR 1926.550 (g) (4). Employees riding in or working from these
lifts shall secure their safety lanyards to the lift basket.
·
Fixed industrial ladders with cages and/or third rail
fall arresting devices are acceptable for travel to work surfaces only.
Secondary Fall
Protection Systems
·
A secondary fall protection system consist of an
approved full body harness and two shock absorbing lanyards. This shall be worn
and used as a backup to primary fall protection systems and in the absence of
primary systems when employees are working six feet or more above the work
surface. “Worn and Used” means that the body harness shall have the lanyards
properly tied off to a tie off point or lifeline systems with positive attachment
100 percent of the time.
·
Only a full body harness and shock absorbing lanyards
capable of supporting 5,400 pounds shall be used.
·
Fall protection lanyards shall be attached to the
D-ring located in the middle of the back of the safety harness.
·
The tie off point must be at waist level or higher and
capable of supporting 5,400 pounds.
·
Lifeline systems are points of attachment for fall
protection lanyards.
·
Lifeline systems must be capable of supporting at least
5,400 pounds.
·
Lifelines may be mounted either vertically or
horizontally and are generally intended to provide mobility to personnel
working in elevated areas.
·
Horizontal lifelines must be made of at least
three-eighths inch wire rope properly supported withstand at least 5,400 pounds
impact and pulled tight to prevent deflection. They must also be marked every
six feet with a high visibility material.
·
Horizontal lifelines shall be positioned so as to
provide points of attachment at waist level or higher.
·
Vertical lifelines are used for fall protection when
vertical mobility is required and may be comprised of static lifelines made of
three-eighths inch wire rope which is equipped with approved sliding rope
grabs, or they may consist of self retracting reel type lanyards/lifelines
which are attached directly to a safety harness.
·
All equipment used in elevated work shall be inspected
prior to each use by the user. Defective equipment shall be tagged “DO NOT USE”
and immediately removed from service.
Steel Erection
·
As each upright steel member is erected the vertical
lifeline shall be attached prior to the member being placed on anchor points
for 100% tie-off points.
·
Each crossmember joist or truss shall be bolted up with
two bolts wrench tight on each end for up to twelve inch beams. Four bolts,
wrench tight on both ends for beams larger than twelve inches. The hoist line
shall remain hooked to the beam or crossmember until connecting bolts are in
place.
·
Full body harnesses with double shock absorbing
lanyards will be worn. Rope grabs shall be utilized on vertical lifelines.
Beamers or beam attachments shall be attached to the crossmembers as erected
for tie-off points.
·
Cooning is mandatory for walking of crossmembers. Where
the crossmember trusses are too deep, then walking the bottom flange is
permitted and a beamer shall be utilized for a tie-off point on the upper
flange.
·
An extension ladder of sufficient and safe height shall
be used on each upright column for access to bolt-up positioning, properly
angled. The top of the ladder and the bottom of the ladder shall be tied off to
the column. The vertical lifeline shall be attached, as indicated in #1, at the
top and tied off to the bottom rung of the extension ladder for the rope grab
tie-off point while ascending and descending the extension ladder.
·
Four upright columns shall be set with the necessary
adjoining trusses bolted up before the steel will be considered safe to leave
for overnight or weekend. If this cannot be accomplished then the steel shall
not be erected and left for the next work day.
·
After the upright columns and trusses are bolted up on
all four sides then, the steel will be judged to be safe for the assembly of
flooring, handrails, and stairs.
·
All steel upright columns are pre-drilled or will be
pre-drilled at six feet above trusses for ½” wire rope lifeline tie-off points.
·
If the handrails are not available at the time of
grating assembly, then ½” wire rope, flagged at six foot intervals, will be
utilized at 21” and 42” height for handrails, perimeter guarding, and tie-off
points.
·
Permanent floors will be erected as the structural
members are installed and there shall be no more than two stories between
floors.
·
Proper barricading and means of safety notification
shall be utilized during steel erection. All personnel shall be notified.
·
One piece of steel shall be lifted at a time, proper
sized rigging and proper tag lines utilized. Material, tools, and equipment needed
for the erection and assembly of the steel shall be raised and lowered by
hoisting.
Aerial Lifts,
Manbaskets and Scissors Lifts.
·
Any type of personnel lift is not to be used for
transporting or lifting members of the structure at any time.
·
Access and egress from any lift will be by the gate
provided in the unit by the maker.
Site Specific
Steel Erection and Fall Protection
·
It is the
responsibility of the site superintendent or his designee to submit a written
site specific steel erection and fall protection plan prior to the start of the
work. He will also be responsible to see all affected employees are trained to
this plan.
·
The superintendent will use the guidelines as set forth
in this program to write the site specific fall protection plan.
OTHER FALL PROTECTION
1. Purpose
The
intent of this procedure is to supplement our standard safety policy with a
standard specifically designed to cover fall protection and to ensure employees
are trained and made aware of the safety provisions that will be used on the
jobsite prior to start of erection.
This procedure should only be used when conventional fall protection is
not feasible or it creates a greater hazard to those employees performing the
work.
2. Responsibility
It
is the responsibility of the superintendent and the project safety coordinator
to devise and write the Fall Protection Plan that will be used at his jobsite
where elevated work will be taking place.
He is also responsible for continual checks of the operation and the
enforcement of this procedure. The
foreman is responsible for correcting any unsafe acts or conditions
immediately. It is the responsibility
of the employees to understand and adhere to the procedure and to follow the
foreman’s instructions. It is the
responsibility of all employees to bring to the attention of the site manager
any unsafe acts or conditions that may cause injury to themselves or others. The safety coordinator must approve the site
Fall Protection Plan.
3. Definitions
a. Controlled Access Zone (CAZ)
Area in which work may take place without
the use of guardrail systems, personal fall protection and safety nets and the
access to the zone is controlled.
b. Not feasible
Impossible to perform construction work
using conventional fall protection or that it is technologically impossible to
use any one of these systems to provide fall protection.
c. Leading Edge
The edge of a floor, roof or formwork for
a working surface which changes location as additional sections are placed or
formed, or an unprotected edge during periods when it in not actively under
construction.
d. Safety Monitoring System
A system in which a competent person is
responsible for recognizing and warning employees of fall hazards.
e. Unprotected Side or Edge
Any side or edge (except points of access)
of a floor, walkway, ramp, roof , or runway where there is no wall or guardrail
system at least 35” high.
f. Warning Line System
A barrier erected on a roof or working
surface that warns employees that they are approaching an unprotected edge,
which designates an area in which work may take place without the use of
guardrails, nets or harness to protect the employees in the area.
4. Plan
Each
site where precast erection and/or leading edge work is to take place shall
have a specific Fall Protection Plan written by the superintendent and approved
by the safety coordinator. This plan
shall include the following seven sections:
I. Fall
protection used on this project.
This section shall list
the optional fall protection listed for the specific areas.
(Warning Line System,
Controlled Access Zone(s), Safety Monitoring System)
Each system used shall
include the following:
a. Name of employee working in the restricted
area and his function.
b. List identifying characteristics of those
employees (different color hard-hat(s), vests, armbands, jackets, etc.)
c. List in detail how the system will be
established (Ref. 1926.502)
II. Implementation
of the Fall Protection Plan.
This section shall give
a brief description of the job and its components and list the products
(decking, grating, slabs, forms, panels) and the detailed erection sequence for
each unit where conventional fall protection is not feasible.
III. Conventional
Fall Protection Considered for the Point(s) of Erection.
Describe in detail why
each conventional means of fall protection could not be used on the job
(guardrails, safety nets, personal fall arrest systems and other measures such
as scaffolds, manlifts, suspended man baskets, etc.).
IV. Training.
Training shall be
conducted by a competent person familiar with the job and the Fall Protection
Plan. The Plan shall be reviewed in its
entirety, including all hazards with those individuals performing the
work. Training shall be documented on a
SMC training log and be kept with the Fall Protection Plan.
Retraining shall take
place if:
1. Changes are made to the plan
2. Conditions to the job are made
3. If employees knowledge or use of equipment
indicate retraining is required.
Retraining
records shall be maintained with the Fall Protection Plan.
V. Enforcement.
Compliance with this
procedure as well as other SMC safety policies are considered conditions of
employment. The superintendent, safety
coordinator and foreman have the right to issue written warnings to employees
including termination for failure to follow the guidelines of this procedure.
VI. Accident
Investigation.
All accidents and
injuries shall be investigated and reported per section 13 of SMC’s Safety and
Lost Prevention Manual.
VII. Changes
to Plan.
The plan will be
reviewed by a competent individual as the job progresses. If a change is required, work will stop on
that portion until the changes to the plan have been made and approved. The superintendent shall make the revision
to the plan and forward it to the project safety coordinator for approval. Once approved, employees shall be retrained
as necessary to the new procedure. A
copy of this plan and its revisions shall be maintained on the jobsite.
