answerHC 1
1.1 Mass explosion hazard (bombs, 155 projectile)
1.2 Fragmentation hazard (some grenades and 105mm cartridges)
1.3 Fire hazard (propellant, artillery charges)
1.4 Minor explosion hazard (small arms ammunition, smoke grenades)
1.5 Very intensive explosives (blasting agents)
1.6 Extremely intensive explosives (no mass explosive hazard)
HC2
β2.1 Flammable gases (acetylene, butane, hydrogen)
β2.2 Non-flammable, non-poisonous compressed gases (helium, nitrogen, and neon)
β2.3 Gases poisonous by inhalation (chlorine, ammonia anhydrous, carbon monoxide)
HC 3
Materials that ignite easily. This is due to flash point. A flash point is the temperature at which a material gives off enough vapor to ignite. (fuel aviation turbine engine (JP-8), gasoline, and some alcohol beverages)
HC 4
β4.1 Flammable solids that catch fire easily (safety or strike anywhere matches)
4.2 Spontaneously combustible materials that can catch fire without a separate heat source (charcoal briquettes, linseed oil)
β4.3 Dangerous when wet materials (materials that can explode or emit flammable gas when in contact with water)
i.e. potassium, sodium, MRE heaters
HC 5
5.1 Oxidizer: materials that does not burn on its own, but gives off oxygen, which could cause other materials to burn
i.e. ammonium nitrate fertilizer, hydrogen peroxide
5.2 Organic peroxide (liquid or solid) that contain oxygen
i.e. polyester resin kits used to patch vehicle tires or repair boats
HC 6
β6.1 Poisonous materials (liquid or solid) so toxic to humans that it is a hazard to health
i.e. potassium cyanide, arsenic
6.2 Infectious substances: an organism that causes virus or infection in humans or animals
i.e. medical waste, virus cultures
HC 7
A radioactive material is any material containing unstable isotopes
I.e. uranium, plutonium, thorium
Note: any time you receive or ship radioactive materials, you must work with your Radiation Safety Officer
HC 8
Materials (liquid or solid) that causes destruction to the human body upon contact (also includes liquids that corrode metals, like steel or aluminum)
i.e. sulfuric acid, hydrochloric acid, sodium hydroxide
HC 9
Material that presents a hazard during transportation and does not fail under any of the other eight hazard classes
I.e. asbestos,, airbag inflators, dry ice when transported by air or vessel, cotton, when transported by land or vessel
