What is the minimum distance to park additional emergency vehicles for effective shielding?

The correct distance for parking additional emergency vehicles to provide effective shielding is critical for ensuring safety at the scene of an incident. Parking at least 150 to 200 feet away from the main working area allows emergency responders to create a barrier that protects both personnel and equipment from hazards, such as moving traffic or potential explosions.

This distance enhances visibility and minimizes the risk of accidents while still providing necessary access for emergency operations. It ensures that vehicles do not obstruct vital routes or create additional hazards for other responders or civilians who may be nearby. Parking beyond this distance helps maintain a safe perimeter around the scene, allowing for effective scene management and operation without compromising the safety of emergency personnel or the public.

Shorter distances, such as those suggested in the other options, might not provide adequate protection or may hinder quick access to the scene, thereby increasing the risks involved in emergency response situations.
