How far must ground motor vehicles stay away from a fuel spill?

Answer: B — 100 feet

Ground motor vehicles must maintain a distance of at least 100 feet from a fuel spill to ensure safety and minimize the risk of fire or explosion. This distance is crucial because fuel spills can create hazardous conditions, including the potential for ignition from sources such as vehicle engines or electrical systems. The 100-foot guideline helps to ensure that any flammable vapors do not reach the vehicle, reducing the risk of combustion and protecting both personnel and property in the vicinity. This precaution is in line with best practices in aviation safety and environmental protection, which emphasize the importance of managing risks associated with fuel leaks. By adhering to this distance, ground vehicle operators are contributing to a safer environment around fuel storage and handling areas, demonstrating an ongoing commitment to safety protocols that are essential in the aviation industry.
