General exam question G0B08
Subelement G0, ELECTRICAL AND RF SAFETY· Group G0B
What should be done before climbing a tower that supports electrically powered devices?
- A.Notify the electric company that a person will be working on the tower
- B.Make sure all circuits that supply power to the tower are locked out and tagged (correct answer)
- C.Unground the base of the tower
- D.All these choices are correct
WhyBefore climbing a tower that supports electrically powered devices, make sure all circuits that supply power to the tower are locked out and tagged. Before climbing a tower that supports powered equipment, every circuit feeding power to anything on that tower must be locked out and tagged so it can't be energized while someone is working on it, answer B. Merely notifying the electric company doesn't physically prevent the tower's own circuits from being switched on, and ungrounding the tower base actually removes a safety protection rather than adding one, so A and C are wrong, and since they're wrong, D's "all of these" is wrong too.
