What is included in Group D of the storage compatibility groups?

Group D of the storage compatibility groups refers specifically to materials that pose similar risks and can be stored together without causing hazards due to their compatibility. Bulk secondary high explosives (HE) and ammunition without initiation are classified in this group primarily because they are stable and less likely to detonate when subjected to accidental conditions compared to materials that require a trigger or initiation device.

This classification allows for efficient storage practices that mitigate the risk of incidents, ensuring that items stored in Group D can coexist safely in close proximity. The compatibility with bulk secondary explosives is important because these materials are often used in military applications and need to be carefully managed to prevent accidental ignition or detonation.

Understanding the nuances of these compatibility groups is essential for maintaining safety standards in hazardous materials storage and handling, which is a key aspect of the Transportation of Hazardous Materials program.
