What does Division 1.3 of Explosives indicate?

Division 1.3 of Explosives refers to materials that present a fire hazard and have a minor explosive hazard. The designation specifically categorizes explosives that are not likely to present a significant risk of detonation but can cause a fire when ignited. These substances can burn rapidly and may produce a weak static pressure wave, but the primary concern is their flammability in the event of an accident or an unintended ignition.

Understanding this classification is essential for handling, transporting, and storing these materials safely, as it informs responders and workers about the appropriate precautions and emergency measures that should be followed. This division conveys that while there is a risk of explosion, the primary risk is related to fire, underlining the need to mitigate flammable exposures in environments where Division 1.3 explosives are present.
