Which hazard should fire fighters remain aware of when carrying long tools, especially pike poles?

When firefighters are carrying long tools such as pike poles, the primary hazard they must be mindful of is overhead wires. This is crucial because long tools can extend a firefighter's reach significantly, increasing the risk of accidental contact with power lines. Such contact can result in serious electrical hazards, potentially leading to injury or even fatalities. Awareness of overhead wires ensures that firefighters maintain a safe distance and navigate their environment carefully, especially in areas where power lines are present.

While tight turns in corridors, auto-closing doors, and moderate or higher winds are all important considerations for firefighter safety, the immediate and critical concern when handling long tools is the risk posed by overhead wires, as the height and the length of the tools can create a significant danger if not managed properly.
