Which is an example of unsafe AE stacking?

Stacking ammunition and explosives (AE) tightly to minimize air circulation is indeed an example of unsafe AE stacking. This practice can lead to several hazards, primarily because proper air circulation is essential to prevent the accumulation of hazardous vapors and to manage temperature. When AE is tightly packed, it restricts airflow, which can cause an increase in temperature and could lead to a fire or explosion. Moreover, it can hinder the effective assessment of the condition of the stored materials and make it difficult to identify any potential issues.

In contrast, leaving gaps between stacks for ventilation is a safe practice that supports air circulation and temperature control. Stacking AE loosely to ease access promotes safety by ensuring that materials can be retrieved without excessive effort and reduces the likelihood of accidents. Utilizing pallets to elevate stacks off the floor is also a recommended safety measure, preventing moisture retention and improving access for inspection and inventory management. Each of these practices enhances safety and compliance with regulations governing the storage of ammunition and explosives.
