Why is maintaining a safe distance from power lines crucial during aerial operations?

Maintaining a safe distance from power lines during aerial operations is crucial primarily because it significantly reduces the risk of electric shock. Aerial ladders and other equipment can easily come into contact with power lines, which can carry high-voltage electricity. If a firefighter or a piece of equipment made contact with these lines, it could lead to severe injuries or fatalities due to electric shock. Adhering to recommended safety distances helps to ensure that personnel are adequately protected from these hazards.

While preventing damage to equipment, ensuring visibility, and allowing for better maneuverability are important considerations in aerial operations, the primary focus when it comes to power lines should be on safety from electrical hazards. Thus, the emphasis on maintaining a safe distance must center on minimizing the risk of electric shock, which is the most critical concern in such scenarios.
