Explosive substances or articles

Division 1.1 Mass Explosion Hazard
Explosives that have a mass explosion hazard. Examples include dynamite, TNT, nitroglycerin, encased explosives, military ammunition, and mercury(II) culminate.

Division 1.2 Projection Hazard
Explosives that have a projection hazard but not a mass explosion hazard. Examples include some types of fireworks, detonating fuses, and ammunition.

Division 1.3 Fire Hazard
Explosives that have a fire hazard and either a minor blast hazard, a minor projection hazard, or both, but not a mass explosion hazard. Examples include smokeless powder, display fireworks, sodium picramate, some liquid and solid propellants, and some rocket motors.

Division 1.4 Package Confined
Explosives that present no significant blast hazard. Examples include signal flares, tracers for ammunition, distress signals, toy caps, empty primed grenades, and some small arms ammunition.

Division 1.5 Insensitive Substances
Explosives with the potential to cause mass explosions, but are so insensitive that the probability of detonation is very low. Examples include an ammonium nitrate-fuel oil mixture that contains only ammonium nitrate in pellet form and fuel oil, and some type B blasting agents.

Division 1.6 Extremely Insensitive Substances
Explosives with extreme insensitivity to ignition, no mass explosion hazard, and a negligible probability of accidental initiation or propagation. Examples include ammonium nitrate, military bombs and missiles, and certain explosive substances in a wet state.
