Study Notes
Introduction to HAZMAT
- In the U.S., hazardous materials are referred to as HAZMAT.
- In Canada, they are classified as Dangerous Goods.
Hazard Classes and Definitions
- The U.S. Department of Transportation (DOT) categorizes hazardous materials into nine classes.
- A weapon of mass destruction (WMD) includes explosive devices that exceed specific weight or charge limits.
- The Environmental Protection Agency (EPA) mandates annual reporting of toxic chemical emissions from specified facilities.
UN and DOT Classifications
- In United Nations regulations, hazardous materials are also termed Dangerous Goods.
- The nine transportation hazard classes encompass:
- Class 1: Explosives
- Class 2: Gases
- Class 3: Flammable Liquids
- Class 4: Flammable Solids
- Class 5: Oxidizers
- Class 6: Poisons
- Class 7: Radioactive materials
- Class 8: Corrosives
- Class 9: Miscellaneous hazardous materials
Class 1 - Explosives Divisions
- Division 1.1: Mass Explosion Hazard
- Division 1.2: Projection Hazard without mass explosion risk
- Division 1.3: Fire Hazard
- Division 1.4: Minor Explosion Hazard
- Division 1.5: Low probability mass explosion hazard (blasting agent)
- Division 1.6: Insensitive articles with no explosion risk
Class 2 - Gases Divisions
- Division 2.1: Flammable Gas (boiling point ≤ 68°F or 20°C)
- Division 2.2: Nonflammable, non-poisonous gases (asphyxiants, oxidizers)
- Division 2.3: Poisonous gases by inhalation
Class 3 - Flammable Liquids
- Flammable liquids encompass materials like gasoline and combustible oils.
Class 4 - Flammable Solids Divisions
- Division 4.1: Flammable solids (includes wetted explosives, self-reactive materials)
- Division 4.2: Spontaneously combustible materials
- Division 4.3: Dangerous when wet, reactive with water
Class 5 - Oxidizers and Peroxides
- Division 5.1: Oxidizers that enhance combustion
- Division 5.2: Organic peroxides containing oxygen in bivalent form
Class 6 - Poisons Divisions
- Division 6.1: Poisonous materials
- Division 6.2: Infectious substances
Class 7 - Radioactive Materials
- Defined as materials with radionuclides exceeding specific activity concentrations.
Class 8 - Corrosives
- Corrosive materials cause full-thickness skin destruction upon contact.
Class 9 - Miscellaneous Hazardous Materials
- Includes materials that pose transport hazards but don’t fit into other classes.
Other Classification Concepts
- Other Regulated Materials are defined as materials presenting hazards based on form, quantity, or packaging.
- Class refers to the primary category, while division represents its subcategory.
Regulations and Awareness
- DOT Class 1 has six specified divisions.
- Mixed loads of hazardous materials cannot be marked for transport.
- Common locations for hazardous materials include gas stations, residential areas, and laboratories.
- HAZMAT incidents commonly occur at port facilities and during floods.
- Personnel at the awareness level must recognize hazards, initiate protective actions, and notify relevant personnel.
