What is one key tactic to avoid when maneuvering around high-voltage lines?

The correct approach when maneuvering around high-voltage lines is to avoid operating the aerial device close to the lines. This is crucial because high-voltage power lines can carry dangerous electrical currents, and proximity can result in serious hazards such as electrical shock or arcing. By keeping a safe distance, firefighters can ensure their safety and reduce the risk of electrical contact.

Maintaining awareness and distance from high-voltage lines is a vital safety consideration in fire ground operations. The other options focus on safety practices and situational awareness, which are important, but none are as critical as ensuring that aerial devices are not operated near these electrical hazards. Familiarity with clearances and the potential dangers associated with high-voltage lines is essential for anyone involved in aerial firefighting operations.
