Question

five engineers were installing a chain link fence in front of a house and directly below a 1200 volt overhead power line. they were installing 91 foot sections of metal top led on the fence. one engineer picked up a 91 foot section of top rail and held it up vertically. the top end contacted the 1200 volt line, and the engineer was electrocuted. what could have prevented this accident? select all that apply? image of a person holding a pole near a power line and a fence options: 1. employers must instruct employees to recognize and avoid unsafe conditions applicable to their work environment 2. using a shorter top rail would have prevented the accident 3. the employee should have de - energized the circuit and grounded it or by guarded it effectively by insulation or other means

Explanation:

To prevent electrical accidents with live circuits, de - energizing and grounding (or proper insulation) the circuit is a key safety measure. Instructing to avoid unsafe conditions is too general, and a shorter top rail isn't relevant to electrical safety here.

Answer:

The employer should have de - energized the circuit and grounded it or grounded it effectively by insulation or other means.
