A safe job begins with a thorough inspection of…
Tools Be certain all of your tools are in good shape.
Equipment Make sure your trucks are all in working order take time to preflight your equipment and insure there are no surprise.
Line/Structure Look over the line and structure. Are there any potential hazards? (Broken insulators, damaged wire, clearances over roads or from trees?)
Be aware of your work area, be sure to cover anything you can reach touch or fall into. And anything that can reach touch or fall into you!
Discuss all PPE needed for the job and wear your PPE. Be sure to inspect your equipment prior to use. Identify all voltages you are exposed to. Be sure to have all of your Arc-Flash protective gear on.
Identify a dedicated observer
Working in traffic exposes you to hazards that are difficult to control. Give the vehicles plenty of time to see and avoid you! Follow the manual of traffic control for your area.
Slips trips and falls are some of the most common injuries, look for hazards that could cause this. Be sure to inspect and wear your fall arrest harness.

5. Make sure to complete your job briefing
Make sure to complete your job briefing. Check the structure and adjacent spans for hazards.

6. Bond the truck to the system neutral.

7. Disconnect the pole ground.

8. Cover the neutral conductor.

9. Move under the neutral and install a cover on the guy wires
Move under the neutral and install a cover on the guy wires. A good trick to keep it up is to use a hot line tap clamped to the guy wire. If you are unable to reach up to completely cover the top guy wire you can join line hose and push it up from further down the guy wire.

10. Move back and up. Install cover-up on the bottom phase wire.

11. Move up and install cover on the center phase wire.

12. Move up and install cover on the top phase wire.

13. Since we will be extending beyond the cover-up to install grips and a hoist add a few more sections of cover-up to the other phases if needed.

14. Move under and install cover to the pole, the ground wire, and exposed hardware. Be sure to not be in contact with the phase cover-up while doing this.

15. Install your slings and insulated link sticks while you are here.

16. Install the conductor grip and hoist to one side and snug it up
Install the conductor grip and hoist to one side and snug it up. Don’t tighten it yet.

17. Install the hoist and grip to the other side and begin to tighten it up.

18. Take up the hoists evenly to remove the strain from the insulator.

19. If you have removed the strain from the insulator you will notice it begins to sag down.

20. Remove the conductor and shoe. Let it gently hang down and clear.

21. Remove the damaged insulator. Be careful of any sharp edges.

22. Install the new insulator.

23. Bring the conductor back up and reconnect it with the insulator and shoe.

24. Let the tension off of the hoists.

25. Remove one of the hoist and grip assemblies.

26. Remove the other hoist and grip assemblies.

27. Move under and remove the links and slings.

28. Remove the pole cover-up.

29. Remove the top phase cover-up.

30. Remove the center phase cover-up.

31. Remove the bottom phase cover-up.

32. Remove the cover-up from the guy wires.

33. Remove the neutral cover-up.

34. Reconnect the ground wire.

35. Remove the truck bond.

36. The job is completed.
