When can explosive items be categorized as 'safe to transport'?

The categorization of explosive items as 'safe to transport' hinges on the criteria of being deemed inert by the Designated Dangerous Agent (DDA). When an explosive item is classified as inert, it indicates that it no longer poses a threat or risk during transport due to its changed chemical properties or that it has been rendered incapable of detonation. This assessment by the DDA is critical because it relies on expertise to ensure that safety protocols are strictly followed, thus mitigating any potential hazards.

While proper labeling, testing, and packaging in standard containers contribute to the overall safety of transporting explosives, they do not guarantee that an explosive item is safe unless it has first been declared inert. Inert status denotes a more definitive safety assurance, which is essential when handling potentially dangerous materials.
