The mandated clearance between buried mortars and the wall of troughs or drums is

Explanation:
Maintaining a small but definite gap between buried mortars and the wall of troughs or drums is a safety buffer. The two-inch clearance provides space to keep heat, flame, and any debris from directly contacting the trough wall, which reduces the risk of damage to the wall, ignition of nearby materials, or a compromised containment during firing or misfires. It also accommodates slight misalignment, thermal expansion, and ease of handling and inspection around the setup. If the gap were smaller, hot debris or heat could jeopardize the trough wall; a larger gap isn’t specified as required by the standard, so two inches is the designated minimum.
