Question

two employees were installing aluminum siding on a farmhouse when it became necessary to remove a 36 - foot high metal pole cb antenna. one employee stood on a nailed pick board between two ladders and unfastened the antenna at the top of the house. the other employee, who was standing on the ground, took the antenna to lay it down in the yard. the antenna made electrical contact with a 7200 - volt power transmission line 10 feet 10 inches from the house and 23 feet 9 inches above the ground. the employee handling the antenna received a fatal shock and the other employee a minor shock. what precautions might have prevented this accident? select all that apply

• do not work near any part of an electrical power circuit which might be contacted in the course of the work
• guard all electrical power circuits against accidental contact by insulating the circuit or de - energizing it
• the nailed pick board shouldnt have been used
• ensure you have training on the hazards of working close to power lines
• another worker should have helped with carrying the antenna

Explanation:

• "Do not work near any part of an electrical power circuit..." prevents proximity to live lines.
• "Guard all electrical power circuits..." insulates/de - energizes to avoid contact.
• "Ensure you have training..." equips with safety knowledge for power lines.
• The metal pick board use is a hazard, but the main issue is electrical contact, so the first three (and the training one) are about electrical safety. The antenna carrying help isn't a direct electrical prevention.

Answer:

• Do not work near any part of an electrical power circuit which might be contacted in the course of the work
• Guard all electrical power circuits against accidental contact by insulating the circuit or de - energizing it
• Ensure you have training on the hazards of working close to power lines
