1. At Compressor Stations: Review blow down, excavation procedures, and policy re: wearing of fire retardant coveralls.
|
|
|
|
2. When using scaffolding around valves, test heads or any other location, make sure there are adjustable screw jack type feet which are set on a solid footing.
|
|
|
|
3. Cutting and pulling fill line over roller - it may twist and turn. Be cautious, don't turn your back on it. Don't get caught between the pipe and welding rig. Park the welding rig away from the pipe.
|
|
|
|
4. Use check valves on test head end of compressor hose in case compressor hose blows - check valves prevents full pipe pressure backing into hose and subsequent violent flogging of hose which can kill or seriously injure workers.
|
|
|
|
5. Pre-test squeeze iron (iron from squeeze pump to test head) to 25%- 50% over test pressure. When using hose it should be certified. Look for tag identifying tested pressure.
|
|
|
|
6. When squeezing ensure only authorized personnel are allowed on site.
|
|
|
|
7. When starting work at a test point and moving pipe apart for pigging and testing procedures, pipe can be sprung - Caution where positioning men - avoid injuries.
|
|
|
|
8. Do not use a 90 degree nipple for blowing down - pressure can twist it off and turn it into a lethal projectile. 45's are better, but the safest blow-down is straight up.
|
|
|
|
9. Clear the area in front of the trap when running the construction pig.
|
|
|
|
10. Always use a bolted door. Don't use doors equipped with pins.
|
|
|
|
11. Do not use slotted pipe in a construction pig. Air comes out too fast and the pig becomes a projectile.
|
|
|
|
12. When laying fill line off R.O.W. check for hazards not identified on R.O.W. assessments, particularly overhead
powerlines.
|
|
|
|
13. When a test is completed, before cutting heads off pipe, check, then double check pressure is off the line - do not take it for granted.
|
|
|
|
14. When air testing, two inch iron is very hot - caution burns.
|
|
|
|
15. When grinding test heads in the ditch, set the head on solid support rather than having it suspended, in case of equipment failure.
|
|
|
|
16. Use Contractor provided LiftAll Tuflex Polyester Roundslings, when lifting test heads. Don’t use owner slings - often they are undersized.
|
|
|
|
17. Expect a pipe wrench to slip - avoid banged up knuckles.
|
|
|
|
18. Check out test heads – Do they have a grating/platform the workers can stand on when hammering wrenches on flange bolts? |
|
|
|
19. Hammer wrenches
 | Always use corresponding socket size for nut size or wrench will jump out of control |
| In confined space get good posture prior to swinging sledge hammer or you will miss the wrench and hit fingers |
| Slow down – don’t get in a hurry – severely crushed fingers are common
|
|
|
|
|
20. Skidding up end of pipe in ditch - watch for others when throwing skids down in ditch - watch toes and shins when building cradle.
|
|
|
|
21. When cutting a section or before booms snug up on belts or pick up any section - Straight wall or sidebend:
| Get workers out of ditch and away from the pipe |
| Get workers out from between pipe and vehicles or equipment. When making a cut, park the welding rig well away from the cut and roll out the hoses. When hooking onto a section, side boom operators are not to snug up belts until foreman gives the signal – even a slight release of pressure on the skid piles can initiate movement of the entire section – this also applies to sections on skid piles above ditch. The section, as it is lifted and pressure comes off the skid piles can be under tension and slam against the ditch wall crushing anyone in the ditch. When making a cut, it can spring violently to one side striking an employee or catapulting him toward any nearby object such as a welding rig. This is particularly common when cutting fill line on the test crew.
|
|
|
|
|
22. When uncoupling water hoses, get a secure grip on the coupling - on stiff hoses the coupling can spring back and hit you in the face.
|
|
|
|
23. Don't walk under a side boom under load - walk around the back of the side boom - equipment can fail.
|
|
|
|
24. Wear safety glasses when hitting clamps, hammer wrench or cable cutter with a sledge hammer.
|
|
|
|
25. Before using Methanol - crew must attend a site specific WHMIS training which includes a review of the Methanol MSDS sheet.
|
|
|
|
26. Welding on windy days - hot slag burns to eyes common - use wind brake.
