For munitions items that have had their explosive filler removed, how many holes are required to be drilled?

The requirement to drill four holes, no smaller than 1/4 inch, in munitions items that have had their explosive filler removed is established to ensure proper drainage and to prevent any potential accumulation of moisture or other substances that could lead to unsafe conditions. Drilling multiple holes allows for adequate ventilation and reduces the risk of pressure buildup within the item.

The specified size of no smaller than 1/4 inch ensures that the holes are sufficiently large to permit effective drainage while also being manageable regarding structural integrity. It is a safety measure that is critical for maintaining the safety and handling of these munitions items post-deactivation.

Understanding and adhering to these guidelines is essential in munitions management to ensure that every step of disposal or deactivation is performed safely and in compliance with regulations.
