What is a common example of Material potentially presenting an explosive hazard?

Munitions debris and targets serve as a common example of material that may present an explosive hazard. This type of material typically comes from military operations, including spent ammunition and other related debris that can retain explosive properties. The potential for these materials to cause explosions or detonate if inadvertently disturbed is a significant safety concern in transportation and handling.

Understanding the context surrounding munitions debris is critical, as it requires specialized training and adherence to stringent safety protocols to manage the risks associated with them effectively. In contrast, the other materials listed, while potentially posing hazards in different contexts, do not inherently carry the same risks associated with explosives, making munitions debris a distinct and recognized category of explosive hazards.
