Which items are classified as Class 1, Division 4?

Class 1, Division 4 items are categorized by their characteristics concerning explosives and their potential hazards. This classification includes items like pistol and rifle ammunition, safety fuzes, and fuze lighters, which are relatively safer under certain conditions compared to more sensitive or dangerous explosives.

Pistol and rifle ammunition falls under Class 1, Division 4 because, although these items are potentially hazardous, they are designed for handling and use in a controlled and safe manner. Safety fuzes and fuze lighters are also classified the same way due to their low risk of accidental detonation as they require specific actions to function—like a firing mechanism or additional components being activated. This makes them significantly safer than explosives categorized in higher divisions.

In contrast, items like high explosive rounds or minefields, which have a greater capacity for unintentional detonation and present higher levels of danger, do not fit within Class 1, Division 4. Such materials are classified in the higher divisions due to their increased sensitivity and risk associated with handling and storage.
