| Warning Diamond | Class/Division | Description | Examples | |
 |
1.1 1.2 1.3 1.4 1.5 1.6 |
Mass explosion hazards Projection hazards Fire hazards No significant hazards Very insensitive Extremely insensitive |
Dynamite TNT Bombs and grenades Sodium pycramate Shotgun cartidges Blasting gel |
|
 |
2.1 | Flammable gases | Acetylene, Butane, Calor gas, Aerosols, Hydrogen, LPG, Methane, Propane | |
 |
2.2 | Non-flammable, non-toxic gases (dangerous because they are compressed or harmful for other reasons eg deprive the air of oxygen) | Argon, Carbon dioxide, Helium, Oxygen | |
 |
2.3 | Toxic gases (so poisonous or corrosive that they are known to be extremely dangerous to life) | Ammonia, Chlorine, Carbon monoxide, Hydrogen chloride, Phosgene, Sulphur dioxide | |
 |
3 | Flammable liquids (ignite easily with a flash point of 60,5 degrees or less) More than 80% of dangerous goods transported belong to Class 3. | Acetone, Benzene, Diesel, Ethanol (alcohol), Petrol, Tar, Toluene. Methylated spirits, Paraffin, Turpentine | |
 |
4.1 | Flammable solids (easily lit by spark or flame or which burn readily or which can catch fire through friction) | Camphor, Matches, Naphthalene, Red phosphorous, Scrap rubber, Sulphur, Wax polish | |
 |
4.2 | Spontaneously combustible (liquids or solids which generate their own heat and which will self-ignite when exposed to air) | Activated carbon, Cotton waste, Fishmeal, Maneb, Metal shavings, Oil/seed cake, Sodium sulphide, White phosphorous | |
 |
4.3 | Dangerous when wet substances (on contact with water may catch fire by themselves or emit flammable or toxic gases) | Aluminium phosphide, Calcium carbide, Lithium, Magnesium powder, Sodium, Zinc dust | |
 |
5.1 | Oxidizers (not necessarily flammable in themselves, they can produce large amounts of oxygen increasing the risk and intesity of fire in other materials) | Ammonium nitrate, Calcium hypochlorite (HTH), Hydrogen peroxide bleach, Lead nitrate | |
 |
5.2 | Organic peroxides (sensitive to heat are thermally unstable and generate large amounts of heat as they breakdown) | Benzoyl peroxide used in acne creams and hair dye, Di-tert-butyl peroxide used to initiate polymerization of ethylene, styrene and vinyl chloride | |
 |
6.1 | Toxic substances (cause illness or death if swallowed, inhaled or if absorbed by the skin) Nearly all emit poisonous gases in a fire | Arsenic, cadmium oxide, Cadmium chloride, Creosote, Cyanides, Phenol, Some pesticides | |
 |
6.2 | Infectious substances (contain bacteria, viruses, parasites and fungi which cause disease in humans and animals) | Medical waste, Pathological specimens, Ebola virus | |
 |
7 | Radio active materials (comprising highly penetrative gamma rays, beta particles which can penetrate skin and alpha particles not hazardous unless swallowed or absorbed through a wound) | Type A medical medication, Nuclear fuel, Cobalt, Radium, Uranium, Plutonium | |
 |
8 | Corrosives (acids and caustic substances in liquid or solid form which chemically eat away a substance and severely damage living tissue) Leakage can also damage other cargo and react with metals used in the construction of vehicles | Acid filled batteries, Hydrochloric acid (spirits of salts and pool acid), Sulphuric acid, Quicklime, Iodine, Lye, Potash, Sodium hydroxide (caustic soda drain cleaner), Soldering flux | |
 |
9 | Miscellaneous (goods which present a danger but cannot be classified in any of the other classes) They include environmentally hazardous substances. | Air bag inflators or modules, Asbestos, Lithium batteries, Expandable polystyrene beads |
