2. Why are we doing this energized?
Take some time to decide if it is necessary to do this job energized.
Could the job be done de-energized and grounded?
What would be the impact?
Would it be safer?

The five topics required by OSHA to discuss in the tailgate.
First letter from each topic = How Well Should Everyone Plan

4. Work Procedures Involved Hazards associated with the job
Special Precautions
Energy Source Controls
Personal Protective Equipment
Be sure to record your emergency location and post in a location everyone on the crew knows.
Have your PPE and First Aid kit available
Be sure your AED is accessible.
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.
Here are the five topics again with signs and bubbles to jump start tailgate discussion!!

Gets the crew involved. Gives the feeling of knowing it is ok to ask questions, give suggestions, see something, say something!
The next slides will get directly into the task at hand. Visual, written and audio will all be used here!
There are suggestions in the notes as to what to discuss. This will get the Team involved, creating communication channels to open!

5. Inspect the structure for additional hazards.
Be sure to inspect the adjacent spans and structures for problems. Look for clearance hazards. Look for trees and traffic that may create a problem.

6. Bond your truck with the use of a hot stick
Bond your truck with the use of a hot stick. Be sure the ground wire is completely unrolled for the reel if used. If it is a spring rewind be sure the reel is locked. Remember truck grounding is done to provide a fast operation of the line protective device if the truck were to become energized. It may not prevent you from being injured if you are touching the earth and the truck at the same time. Don’t allow anyone to come into contact with your truck while you are doing this job!

7. Open the pole ground connection to the neutral.

8. Install cover-up to the neutral.

9. Cover-up the neutral jumper and dead ends.

10. Install cover-up to the guy wire
Install cover-up to the guy wire. The use of a hot tap will help keep these in position.

12. Install cover-up to the suspension insulators.

13. Install cover-up on the exposed structure
Install cover-up on the exposed structure. Start low and work your way up to the top of the pole. Make sure you are not in contact with the phase cover-up when doing this.
This is also a good time to install the sling around the top of the pole near the insulator you will be changing out. You can connect the insulating link to the sling as well.
