Is stacking off-loaded canisters on top of one another considered a caution in the Drill manual?

Stacking off-loaded canisters on top of one another is indeed considered a caution in the Drill manual because this practice can lead to significant safety risks and operational hazards. When canisters are not designed to be stacked, doing so can compromise their structural integrity and increase the chances of accidents, such as tipping over or damaging the canisters, which could result in dangerous spills or leaks of propellant. The Drill manual emphasizes the importance of adhering to specified safety protocols to prevent incidents that could harm personnel and equipment. Following these guidelines ensures a safe and effective working environment, particularly when handling potentially hazardous materials like missile canisters.
