Study Notes
Hazardous Materials Classes
- Class 1: Explosives, highly reactive substances that can cause explosions under certain conditions.
- Class 2: Gases, which can be compressed or liquefied, posing risks such as flammability or toxicity.
- Class 3: Flammable liquids, substances that can ignite and sustain combustion.
- Class 4: Flammable solids, materials that can catch fire easily and burn rapidly.
- Class 5: Oxidizers and organic peroxides, substances that can contribute to combustion and amplify fire hazards.
- Class 6: Poison, materials that can cause harm through exposure or ingestion.
- Class 7: Radioactive materials, substances emitting ionizing radiation, posing health risks.
- Class 8: Corrosives, chemicals that can damage skin, eyes, or materials upon contact.
- Class 9: Miscellaneous materials, substances that do not fit into other hazardous classes.
NFPA Standards
- NFPA 473: Establishes competencies for EMS personnel responding to hazardous materials and WMD incidents.
- NFPA 1072: Defines qualifications for emergency response personnel in hazardous materials situations.
- NFPA 704: Provides a standardized system for identifying material hazards for emergency response.
- NFPA 472: Sets competence standards for responders to hazardous materials and WMD incidents.
