How many feet is the firebreak around the ventilators of earth-covered magazines?

The firebreak around the ventilators of earth-covered magazines is specified to be 5 feet. This distance is mandated to ensure safety and reduce the risk of fire spreading in the event of an incident. Firebreaks serve as a critical safety measure, as they create a buffer zone that helps protect the magazine from external fires that might reach the storage area through the ventilators. The 5-foot clearance is a standard guideline, specifically designed to maintain a safe environment around explosives and munitions storage facilities. Adhering to this measurement is essential for compliance with safety regulations and best practices in munitions handling.
