1. Explosives. Explosives meet the hazardous materials classification (Class 1) because they have the ability to produce hazardous amounts of heat, sound, smoke, gas or light.
2. Gases. Gases include compressed, liquefied, dissolved, refrigerated liquefied, aerosols, and other gases. They are defined by the hazardous materials classification (Class 2) as “substances that have a vapor pressure of 300 kPa or greater at 50°c or are completely gaseous at 20°c at standard atmospheric pressure.”
3. Flammable Liquids and Combustible Liquids. Flammable liquids or combustible liquids are volatile, and can often give off a flammable vapor. They are defined by the hazardous materials classification (Class 3) as “liquids, mixtures of liquids or liquids containing solids in solution or suspension which give off a flammable vapor, and have a flash point at temperatures not more than 60.5°C or 141°F.”
4. Flammable Solids and Spontaneously Combustible Materials. Flammable solids fit within the hazardous materials classification (Class 4) because they are highly combustible, are capable of posing serious hazards due to their volatility, combustibility, potential in causing or propagating severe conflagrations and can even cause fire through friction.
5. Oxidizers and Organic Peroxides. Oxidizers are substances that can produce oxygen. They are within the hazardous materials classification (Class 5) because the right circumstances they can contribute to the combustion of other hazardous substances, though they are not always combustible themselves.
6. Toxic Materials and Infectious Substances. Toxic materials fall under the hazardous materials classification (Class 6) because of the ability to cause serious injury or death if swallowed, inhaled or contact is made with skin.
7. Radioactive Materials. Radioactive materials are defined by hazardous materials classification as “any material containing radionuclides where both the activity concentration and the total activity exceeds certain pre-defined values.”
8. Corrosive Materials. Corrosive are substances that degrade or disintegrate other materials upon contact through a chemical reaction if leakage, or damage occurs to the surrounding materials.
9. Miscellaneous Dangerous Goods. As the name implies, miscellaneous hazardous materials classification (Class 9) are substances that present an imminent threat that is not covered within the definitions of the other 8 classes.
