a maintenance project along a major expressway intersects with the path of utility poles carrying very high voltages (3,000 volts or more). the simplest, most easily available scaffolding was prefabricated steel, and you are concerned about possible electrical safety implications. according to this module, which of the following actions would be your first priority as the \competent person\ at the jobsite?
select your answer by pressing the letter.
(a) ensure that each scaffold is grounded.
(b) instruct employees to wear non - conductive footwear while on the scaffold.
(c) make sure each scaffold maintains a minimum clearance of 10 feet from the power lines.
(d) place a rubber mat beneath each scaffold, keeping them insulated from the ground.

Explanation:

When dealing with high - voltage utility poles near scaffolding, maintaining a safe distance is crucial. Grounding the scaffold (A) may not prevent electrical arcing if too close. Non - conductive footwear (B) is not the first priority as it doesn't address the overall proximity risk. Insulating from the ground (D) is less important than maintaining a distance from the power lines. A minimum clearance of 10 feet from power lines (C) helps avoid electrical contact and arcing, which is the most immediate safety concern.

Answer:

C. Make sure each scaffold maintains a minimum clearance of 10 feet from the power lines.
