A no-entry zone around a fire on a utility pole should be at least:

The appropriate safety measure when dealing with a fire on a utility pole involves establishing a no-entry zone that is effective in managing the potential hazards associated with the situation. The correct answer emphasizes the need for a no-entry zone that is at least equal to the distance between utility poles. This distance accounts for the risk of falling debris or potential electrical hazards, as maintaining a safe perimeter ensures that personnel are not exposed to these dangers.

Setting the no-entry zone based on the distance between the poles allows responders to remain at a safe working distance while also considering the vertical nature of the pole and any potential incidents that could occur, such as the fire spreading or components falling. This precautionary approach is essential in fire safety and incident management, as it promotes safety for both responders and the public.
