Hazard Classification Code
The UN hazard classification system for classifying explosive materials and explosive components is recognized internationally and is used universally by the Department of Defense (DoD), other Department of Energy (DOE) contractors, and the Department of Transportation (DOT). The UN system consists of nine classes of dangerous materials, with explosives designated as Class 1. The explosives hazard class is further subdivided into six divisions, which are used for segregating ammunition and explosives on the basis of similarity of characteristics, properties, and accident effects potential.

1.3 Mass fire, minor blast or fragment
1.4 Moderate fire, no blast or fragment
