Which behavior is considered unsafe at the scene of vehicle collisions?

Not wearing proper protective gear is considered unsafe at the scene of vehicle collisions because it exposes responders to various hazards that can cause injury or illness. First responders, including emergency medical personnel and firefighters, are often confronted with risks such as broken glass, sharp metal edges, exposure to hazardous materials, and potential fire or explosion hazards. Proper protective gear, such as helmets, gloves, high-visibility vests, and eye protection, is designed to mitigate these risks and protect individuals while they perform their duties in a potentially dangerous environment. Ensuring that all personnel wear the appropriate gear is crucial for maintaining safety and effectiveness in emergency response situations.
