Which of the following is a common example of fireground hazards?

Downed power lines are a prevalent example of fireground hazards because they pose significant risks during firefighting operations. When power lines are downed, they can lead to electrocution hazards for firefighters and emergency responders. The presence of live wires on the ground can create an unsafe environment, where individuals may inadvertently come into contact with the electrical current. This scenario calls for caution and specific safety protocols to ensure that responders can operate without the risk of severe injury or fatalities.

Other hazards such as excessive personnel on site, weather changes, or inadequate lighting can also present risks and complicate firefighting efforts, but downed power lines are particularly dangerous due to their immediate and life-threatening potential. The reality of encountering downed power lines makes this hazard a critical part of training and preparedness for anyone involved in fire operations.
