RUEGOS Y PREGUNTAS:

This section provides specific guidelines for most areas of pipeline construction. All employees must carefully read it. However the directives here must work with information contained in all previous sections, particularly" VEHICLE MOVEMENT AND EQUIPMENT CONTROL AND GENERAL TRANSPORTATION GUIDELINES" and "HEAVY EQUIPMENT FOR CONSTRUCTION" and "TRENCHING AND SHORING". Common sense, a serious concern for safety and a thorough understanding of approved procedures will always make the jobs site safer for all.

Unloading and Stringing Pipe.

1. In transporting pipe, a red flag must always be used at rear .end or trucks, fence gaps must be kept closed and trucks are to stay on the right of way.

2. There must always be suitable signage or flags on roads where trucks will be turning off string pipe.

3. All workers are to be kept in the clear while cutting steel bands securing pipe to any vehicle.

4. Lifting equipment must be carefully spotted while unloading pipe to make sure of full clearance of overhead service wires. High voltage electric-power lines are a serious hazard.

5. Any necessary skid ramps must have a gradual incline, be firmly attached, constructed of sound hardwood and of sufficient size to support their load. Any long skids must be supported.

6. Pipes being moved along skid ramps must extend at least four feet on each side. Workers handling pipe must work at these ends to avoid danger of being caught between sections.

7. Tail ropes must be long enough for workers hooking pipe to stand clear while guiding it.

8. When spacers are used for racking, each tier of pipe must be scotched.

Ditching Operations

1. Before any ditching operations may be started, site must be thoroughly checked for all underground cables, oil and gas lines, conduits and other pipelines. Any necessary permits must be obtained and the supervisor must give the go ahead.

2. The ditching machines operator is responsible for the maintenance of his machine and equipment and is to keep it in good working order.

3. Guards must be properly maintained and in position while ditching machine is operating.

4. Whenever worker are digging or otherwise working in. ditch, the spoil-bank must be kept well back from the ditch's edges.

5. Signalmen directing clamshell or bucket operations must stand clear of the edge of the ditch.

Cutting and Bending Pipe

1. The bending machine operator must make a daily inspection of all clamps, cables, brakes and other systems affecting the safe operation of the machine. Any defects must be reported and repaired by authorized personnel.

2. All rules on tractor operations as well as those outlined for power machinery are to be applied to all bending operations.

3. Workers are always to be in clear during actual bending.

4. During cutting, pipes must always be fully supported. In any case where short sections may be allowed to drop, all workers are to remain clear of falling pipe.

5. No one is to rode pipe being transported to or from bending machines.

Laying the Pipe

1. Pipe should always be handled from the sides; hands are not to be placed over the ends of pipes.

2. All workers handling skids must wear leather-palmed gloves.

3. Any material used as skids must be carefully inspected before use, must be of adequate size for the job and free of any hazardous defects. Broken or defective skids must be destroyed.

4. A maximum of four skids may be placed together. If more are needed, a four square crib must be built for pipe support In this or any construction or activity, hammers must be handled carefully to avoid injury.

5. Pipe must be set securely on skids, and scotched at intervals and ends to avoid movement.

6. Before transporting skids, boom them firmly to the truck bed.

7. Once the calliper or cable has been attached, workers must immediately move from under the boom.

Hot Tar and Dope Kettles

Work in these areas can be particularly hazardous if extreme care is not taken with all phases of these operations. All workers must be thoroughly trained in proper procedures and must read

the information in this chapter as well as all other relevant material of this HAZCON manual, including specifically areas on personal protective gear, good housekeeping, fire prevention and flammable liquids.

General Precautions:

1. Only personnel expressly trained for experienced in and familiar with the job may operate dope kettles. Kettles fire-fighters must be warned of the possibility of flashbacks.

2. A first aid emergency kit containing eye flushing agents and any other treatment for eye irritants bust is readily available.

3. There must be a CO2 or dry powder fire extinguisher near the work at hand.

Protective Gear and Measures:

1. All workers handling or working near primer or hot dope must wear top shoes or boots with trousers out and full-length sleeves rolled down over the tops of gloves.

2. Approved goggles must be worn by all involved in dope cutting or charging kettles. Workers MUST use face shields while loading kettles.

3. Approved goggles and respirators are mandatory in all phases of these operations where dust, fumes, rust or oilier irritants are possible hazards.

4. Protective cream is to be provided and used at any time fumes could cause skin irritation. This must be applied before work begins.

5. The area around the heating kettle must be kept clear. There must be no random items or equipment about which could cause tripping or stumbling. All materials must be kept at least five feet away from the kettle or other heating element; ALL COMBUSTIBLE MATERIALS must be stored, with proper protection, at least 20 feet away.

Equipment Inspection and Maintenance:

1. All equipment must be carefully inspected, by qualified personnel, before each job. All pressure tanks, hoses, fittings, clamps and other components from pressure fuel chambers to burners must be examined daily.

2. Burners must be regularly cleaned.

3. All dope kettles must have downspouts and quick-closing cut-off valves. No defective buckets may be used,

General Operations:

1. Caps or plugs are always to be removed slowly and with care to allow for any built-up pressure.

2. Never fill buckets to greater than 2/3 capacity to prevent splashing.

3. The temperature of hot tar or dope in a kettle must be carefully maintained to avoid ignition.

4. In case of a fire in the kettle, quickly close the lid tightly and close the burner valve. This should kill the fire. If not, use a dry powder or CO-2 extinguisher. When the kettle lid is again to be raised, all workers should stand back in case oxygen revives the fire.

5. In moving a small kettle, always keep the lid close', the fire cut down and all employees clear.

6. While balancing the cleaning and wrapping machine, workers are NOT to place their bodies over outrigger poles. The poles must be held with hands.

1. All workers must follow requirements not only of this section, but also all other areas of this manual concerning trenching, excavations, cranes, construction equipment and material handling

2. Only the crew foreman may signal tractor operators during operations. All signals must be those commonly understood and in keeping with prevailing industry usage.

3. All necessary precautions must be taken to prevent tractor's falling into ditches while pipe is being lowered.

4. Belt slings and boom lines must be hooked to the boom while a tractor is in motion. Belt slings and wire rope connections must be checked before each lowering procedure.

5. While pipe is being lowered, no worker may be in the ditch, on the pipe or in any area between the ditch and the section of pipe being lowered.

6. All hellholes must be large enough and correctly sloped so that welders and other workers therein are protected from cave-ins.

Clean-Up

At the conclusion of construction operations, HAZCON’S goal is to have left the worksite in a condition as near as possible to the state in which it was found.

Workers involved in backfill are to proceed according to all the rules outlined in this and preceding chapters, with particular care to keep machines on the right-of-way. Crops and other property are to be treated with respect and care. Clean-up gangs must remove ALL debris, including but not limited to dynamite wrappers, chunks of tar or dope and all paper, metal or glass pieces to prevent injury to animals and preserve the order of the land.
