What term is used to describe items that have had their explosive material removed and not replaced?

The term used to describe items that have had their explosive material removed and not replaced is "Deactivated." When an explosive device is deactivated, it indicates that its capacity to function as an explosive has been neutralized through various means, such as removing the explosive components or rendering them safe. This term is formally recognized in safety and ordinance handling contexts, signifying that the item is no longer a threat.

In contrast, "Empty" refers to a state where something has been completely voided of its contents, but it does not specifically denote that an explosive device has been neutralized. "Dormant" implies that something is inactive but could potentially become active again, while "Vacant" usually describes a position or location that is unoccupied, not an explosive device. Thus, deactivation is the most appropriate and accurate term in this context.
