What is the visibility requirement for fuel shutoff signage during emergencies?

• A. 50 feet
• B. 75 feet
• C. 100 feet
• D. 125 feet

Answer: (C)

The visibility requirement for fuel shutoff signage during emergencies is set at 100 feet to ensure that responders can quickly locate the shutoff in high-stress situations. This distance is crucial for the safety of both emergency personnel and potentially affected individuals, as it allows for a prompt response to mitigate fire hazards or hazardous spills effectively.

Having the signage visible from this distance helps prevent confusion and delays in accessing vital safety equipment during emergencies. The choice of 100 feet strikes a balance between visibility and practicality, considering the operational dynamics of an airport environment, where rapid response is essential. Signage that is too far or too close may impair the effectiveness of emergency measures, making the 100-foot requirement the most effective standard to abide by.
