What is the minimum distance a fuel vehicle must park from airport buildings?

The correct answer is based on safety regulations regarding the parking of fuel vehicles near airport buildings. Parking a fuel vehicle at least 50 feet away from airport buildings is established to minimize the risk of fire hazards and explosions, which can have serious consequences in the vicinity of passenger terminals and other structures. This distance allows for better safety protocols to be followed, ensuring that in the event of a fuel leak or incident, there is sufficient space to avoid danger to personnel and building infrastructure. Distances less than this could pose significant risks not only to airport operations but also to public safety. The requirement reflects a balance between operational practicality and necessary safety measures in the context of handling flammable materials near sensitive environments like airports. Other specified distances would not provide the same level of safety and risk mitigation.
