Munitions are grouped into the same hazard division when they have?

Munitions are grouped into the same hazard division based on their like explosive characteristics. This categorization is essential for safety and regulatory compliance, as it helps ensure that munitions with similar properties—such as sensitivity to heat, shock, or friction—are stored and handled together. By assessing the explosive characteristics, transportation and storage practices can be designed to mitigate the risks associated with handling different types of explosives. Such an approach is vital for maintaining safety during operations and ensuring that personnel are adequately informed about the munitions they are working with. The other options relate to aspects of appearance, storage, or packaging, but do not directly influence the hazard categorization that focuses on the intrinsic explosive qualities of the munitions.
