How far must one stay away from spilled substances on the runway?

Staying a safe distance away from spilled substances on the runway is critical for ensuring safety and preventing accidents. The correct answer of 50 meters is established as the minimum safe distance to minimize the risk of exposure to hazardous materials or potential explosions, as well as to provide sufficient space for emergency response vehicles to operate effectively. This distance helps protect personnel working in the area, as well as passengers and aircraft, from the dangers that spills can pose. In operational guidelines, this recommended distance reinforces the importance of maintaining awareness of hazardous materials and the appropriate response procedures, ensuring that safety protocols are followed rigorously in an airport environment.
