Study Notes
Hazard Classes Overview
- There are 9 hazard classes defined for categorizing dangerous goods.
Hazard Class Summaries
- Hazard Class 1: Explosives.
- Hazard Class 2: Gases, including flammable, non-flammable compressed, and toxic gases.
- Hazard Class 3: Flammable liquids, defined as any with a closed cup flash point of 60°C or below.
- Hazard Class 4: Flammable solids, substances liable to spontaneous combustion, and substances emitting flammable gases when in contact with water.
- Hazard Class 5: Includes oxidizing substances and organic peroxides, with two divisions for oxidizers and peroxides, respectively.
- Hazard Class 6: Toxic and infectious substances, with divisions categorizing toxic and infectious materials.
- Hazard Class 7: Radioactive materials, which encompass all radioactive substances.
- Hazard Class 8: Corrosives, involving all substances that can corrode materials or tissue.
- Hazard Class 9: Miscellaneous dangerous goods presenting a danger during air transportation but not covered by other classes.
Divisions of Hazard Classes
-
Class 1 Divisions:
- 1.1-1.6 includes various types of explosives; 1.4 specifically refers to explosives that present minimal risk.
-
Class 2 Divisions:
- 2.1: Flammable gases.
- 2.2: Non-flammable, compressed gases.
- 2.3: Toxic gases.
-
Class 3 Division:
- Any liquid with a closed cup flash point of 60°C or below qualifies as flammable.
-
Class 4 Divisions:
- 4.1: Flammable solids (e.g., matches, sulfur).
- 4.2: Substances that can spontaneously combust (e.g., white phosphorus).
- 4.3: Substances emitting flammable gases in contact with water (e.g., sodium).
-
Class 5 Divisions:
- 5.1: Oxidizers (e.g., ammonium nitrate).
- 5.2: Organic peroxides (e.g., hardeners for fiberglass repair kits).
-

-
Class 8 Division:
- Includes all corrosive substances (e.g., strong acids).
-
Class 9 Division:
- Covers any additional substances that pose a transportation danger not classified elsewhere (e.g., lithium batteries, asbestos).
Examples of Hazard Classes
