When is it acceptable to drive a fire apparatus over a downed power line?

Driving a fire apparatus over a downed power line is never an acceptable practice due to the significant safety hazards it poses. Downed power lines can be energized, and there is a risk of electrocution to both firefighters and civilians. Electricity can travel through the ground, creating a wider danger zone, and if a vehicle drives over a power line, it can also create a situation where tires become energized.

Furthermore, power lines can sometimes appear motionless and silent but still be live, posing unpredictable dangers. The safest course of action in any incident involving downed power lines is to maintain a safe distance, alert the utility company, and wait for trained professionals to make the area safe. Safety for the crew and the public is paramount, and engaging with downed lines in any manner that risks exposure to electrical hazards is strictly against safety protocols and best practices in firefighting.
