How frequently should emergency fuel shutoff systems be tested?

• A. Monthly
• B. Every 3 months
• C. Every 6 months
• D. Annually

Answer: (D)

Emergency fuel shutoff systems are critical for maintaining safety in airport operations, especially in the event of a fuel spill or fire. The recommended testing frequency for these systems is annually. This annual testing ensures that the systems function correctly and can be activated quickly in emergencies. Regular testing is crucial to confirming that all components, including switches and valves, are operational and that the system's response time meets safety standards.

Testing annually allows for comprehensive checks that are necessary to identify any potential issues or wear in the system, which might not be evident with more infrequent testing. While more frequent testing may seem beneficial, it is generally understood that an annual schedule balances safety needs with practical maintenance resources. Consequently, following this yearly protocol ensures compliance with safety regulations while enabling optimal performance in emergencies.
