Classes of Hazardous Materials
-
Class 1: Explosives
- Materials designed to release energy rapidly.
- Considered extreme hazards near fire.
- Examples: dynamite, black powder, small arms ammunition.
-
Class 2: Gases
- Materials in gas form at normal temperatures, contained under pressure.
- Can be flammable, non-flammable, poisonous, or corrosive.
- Examples: acetylene, hydrogen, anhydrous ammonia.
-
Class 3: Flammable Liquids
- Liquids that ignite easily in the presence of an ignition source.
- Examples: gasoline, diesel fuel, acetone.
-
Class 4: Flammable Solids
- Solids that catch fire easily and may ignite spontaneously or when wet.
- Examples: magnesium, sulfur, calcium carbide.
-
Class 5: Oxidizers and Organic Peroxides
- Substances that can cause spontaneous combustion or intensify fires.
- Examples: bromine, calcium hypochlorite (bleach).
-
Class 6: Toxic Materials and Infectious Substances
- Includes harmful materials such as medical waste and biological hazards.
-
Class 7: Radioactive Substances
- Consists of nuclear waste and materials like radioactive medical supplies and X-ray equipment.
-
Class 8: Corrosive Substances
- Substances that can irreversibly damage living tissue or materials.
- Includes various acids and solvents.
-
Class 9: Miscellaneous Dangerous Goods
- Goods that do not fit into Classes 1-8 but still pose risks.
- Examples: molten sulfur, PCBs (polychlorinated biphenyls), hazardous waste.
Important Notes on Classes
- Each class is defined based on the potential hazards they present.
- Emergency responders must be cautious and aware of the risks associated with each class during incidents.
