ORS 480-200 defines “Explosive” as a chemical compound, mixture or device, the primary or common purpose of which is to function by explosion. The term includes, but is not limited to, dynamite, pellet power, initiating explosives, detonators, safety fuses, squibs, detonation cord, igniter cord and igniters, but excludes fireworks as defined in ORS 480-110, primers and fertilizer, as defined in ORS 633.310.
Explosives are divided into two distinct groups:
Low explosives deflagrate (burn) rather than detonate (explode). These are primarily used as propellants. The arbitrary cut-off speed between high and low explosive is 3,300 fps (feet per second). An example of a low explosive if black powder.
High explosives shatter. Detonation velocities for high explosives range from 3,300 fps to 29,900 fps. Examples of high explosives include blasting caps, dynamite, TNT, plastic explosives, binaries and blasting agents.
Explosives should not be handled and are dangerous.
