Some items included in explosive class/division 1.2 are?

Items categorized in explosive class/division 1.2 are recognized for producing a low probability of incident, but they can still create a significant hazard under specific conditions. In this context, both 20mm and 30mm ammunition fall into this classification due to their design and intended use in military applications. This ammunition is designed to be used in automatic weapons systems, where it is essential to control and handle it carefully to ensure safety.

On the other hand, hand grenades are classified as explosive class/division 1.1, which indicates a higher level of risk due to their immediate detonation upon activation. Semi-automatic rifles, while they may utilize ammunition in this class, do not themselves fall under the category of explosives and do not produce an explosive reaction without ammunition. Demolition explosives would also generally align with a higher risk classification compared to class/division 1.2 due to their function and potential for a more catastrophic explosive event.
