How often must ARFF personnel conduct live fire drills?

The correct interval for conducting live fire drills for Aircraft Rescue and Fire Fighting (ARFF) personnel is once a year. This annual requirement ensures that ARFF personnel maintain their skills and readiness to respond effectively to aircraft emergencies. Regular practice through live fire drills reinforces the critical operational skills needed during an emergency, helps personnel stay familiar with equipment and protocols, and enhances teamwork and communication in high-stress situations.

While the other options suggest more frequent or less frequent intervals, those do not meet the established guidelines. Monthly drills may lead to unnecessary resource strain and operational fatigue, and every three months could potentially result in skills decay between drills, which is not optimal. Conducting drills once every two years does not provide sufficient practice to ensure that personnel remain proficient in their duties, especially in a rapidly changing environment where technology and procedures may evolve. Thus, the annual frequency strikes an appropriate balance to keep fire service personnel adequately trained and ready for emergency responses.
