What is the minimum distance a fire apparatus should be from downed electrical wires?

• A. At least one utility pole span.
• B. Directly under the wires for stability.
• C. At least three lengths of firefighter hose.
• D. One block away.

Answer: (A)

The key safety rule is to treat downed power lines as energized and keep a generous buffer between the apparatus and the wires. The minimum distance is at least the length of a utility pole span, which means staying far enough away to avoid any chance of arcing or the line shifting into contact with the vehicle or crew. This span-based distance gives a concrete, measurable safety margin that works across different street layouts and line sag. Staying directly under the wires is dangerous because electricity can arc through the air or energize the ground and anything touching it. The idea of using three lengths of hose or a vague “one block” distance doesn’t provide a reliable or protective standard. When encountered, establish and maintain that one-pole-span buffer and contact the utility to de-energize the line before approaching more closely.
