In securing buried mortars, the separation from the wall of troughs or drums should be at least?

Explanation:
Maintaining a small air gap between buried mortars and the enclosing trough or drum wall is a safety spacing measure. The two-inch separation provides enough clearance to limit heat transfer and venting issues, reducing the risk that heat or flame could affect the wall or neighboring items. If the gap were smaller, heat and pressure could transfer more readily to the wall; if it’s larger, it’s not required by standard practice and just takes up space. So, the required separation is two inches.
