In which storage compatibility group are secondary explosives without their own means of initiation classified?

Secondary explosives that do not possess their own means of initiation are classified as Group E within the storage compatibility groups. This classification is significant because it helps to identify the handling and storage requirements specific to these materials. Group E covers substances that are typically more stable and less likely to initiate on their own compared to primary explosives, which are known for their sensitivity to heat, shock, or friction.

Grouping materials according to their compatibility helps ensure safety by minimizing the risk of unintended reactions during storage or transportation. Secondary explosives, like those in Group E, may still react under certain conditions but are generally handled and stored with less stringent controls compared to those in other groups. This understanding is essential when developing emergency response plans, conducting risk assessments, and establishing transportation protocols for hazardous materials.
