  1. Awareness-Level Lesson 1 Presentation Hazardous Materials for First Responders, 3rd Ed.

  2. Haz Mat Incidents • Involve a substance that: • Poses an unreasonable risk to: • People • Environment • Property • Has been or may be released from a container • May be on fire • Will be more complex than a “routine” incident Awareness Level

  3. Other Emergencies • Do not involve the release of a hazardous substance Awareness Level

  4. Awareness-Level Training Requirements • Governmental agencies • OSHA and EPA • U.S. Department of Justice, Office for Domestic Preparedness (ODP) • Requirements of authority having jurisdiction (AHJ) (1 of 2) Awareness Level

  5. Awareness-Level Training Requirements • NFPA Standards • NFPA 472, Standard for Professional Competence of Responders to Hazardous Materials Incidents • NFPA 471, Recommended Practice for Responding to Hazardous Materials Incidents • NFPA 473, Standard for Competencies for EMS Personnel Responding to Hazardous Materials Incidents (2 of 2) Awareness Level

  6. Awareness-Level Responsibilities • Recognizing the presence or potential presence of a hazardous material • Recognizing container type and identifying material • Transmitting information to appropriate authority and calling for assistance • Identifying actions to protect self and others • Establishing scene control Awareness Level

  7. U.S. Agencies Regulating Hazardous Materials • Department of Transportation (DOT) • Hazardous materials in all modes of transport • Environmental Protection Agency (EPA) • States and tribes enforce compliance • Department of Labor • OSHA issues legislation regarding worker safety • Nuclear Regulatory Commission • Regulates nuclear and radioactive materials Awareness Level

  8. Canadian Agencies Regulating Hazardous Materials • Transport Canada (TC) • Environment Canada • Health Canada • Canadian Nuclear Safety Commission Awareness Level

  9. Products Most OftenInvolved in Haz Mat Incidents • Flammable/combustible liquids • Corrosives • Anhydrous ammonia • Chlorine Awareness Level

  10. Hazardous Materials States • Hazardous materials may be: • Elements • Compounds • Mixtures • May be found in gaseous, liquid, or solid states or a combination of these states (1 of 2) Awareness Level

  11. Hazardous Materials States (2 of 2) Awareness Level

  12. Hazardous Materials Hazards • May present a direct threat to health or pose physical hazards • Hazards range from insignificant to catastrophic • Exposure may be acute or chronic • Health effects can be acute or chronic Awareness Level

  13. Hazardous Materials Behavior • Behavior of hazardous material — A material’s physical state, flammability, boiling point, chemical reactivity, and other properties • Affect how it behaves • Determine harm • Influence effects of hazardous material Awareness Level

  14. Open flames Static electricity Existing pilot lights Electrical sources Internal combustion engines Heated surfaces Cutting and welding operations Potential Ignition Sources at Haz Mat Scenes (1 of 2) Awareness Level

  15. Radiant heat Heat caused by friction or chemical reactions Cigarettes Cameras Road flares Potential Ignition Sources at Haz Mat Scenes (2 of 2) Awareness Level

  16. Potential Ignition Sources in Explosive Atmospheres • Opening or closing a switch or electrical circuit • Turning on a flashlight • Operating a radio • Activating a cell phone Awareness Level

  17. Thermal Radiological Asphyxiation Chemical Etiological Mechanical Psychological NFA Categories of Hazardous Materials Hazards Awareness Level

  18. Thermal Mechanical Poisonous Corrosive Asphyxiation Radiation Etiologic Psychological NFPA Categories of Hazardous Materials Hazards Awareness Level

  19. Thermal Hazards — Cold Temperatures • Cryogenic and liquefied gases • Freeze burns and cold injuries • Anhydrous ammonia • Cold injuries • Vapors are toxic and may catch fire Awareness Level

  20. Thermal Hazards — Elevated Temperatures • A concern when dealing with materials such as molten sulphur and molten aluminum • High temperature materials can ignite flammable/combustible materials • Thermal burn types include first, second, and third degree burns Awareness Level

  21. Radiological Hazards • A concern at facilities such as medical centers, industrial operations, nuclear power plants, and research facilities, and terrorist attacks • Damage cells and can cause noticeable health effects Awareness Level

  22. Asphyxiation Hazards • Asphyxiants affect the oxygenation of the body and lead to suffocation • Simple asphyxiants — Gases that displace the oxygen necessary for breathing • Chemical asphyxiants — Substances that prohibit the body from using oxygen Awareness Level

  23. Chemical Hazards • Produce a wide range of adverse health effects depending on: • Toxicity of the chemical • Route of exposure • Nature and extent of exposure • Factors that affect the susceptibility of the exposed person (1 of 2) Awareness Level

  24. Chemical Hazards • Local toxic effect — A chemical injury at the site of contact • Systemic effects — Effects produced when a toxic chemical is absorbed into the bloodstream and distributed to other parts of the body (2 of 2) Awareness Level

  25. Etiological Hazards • Exposure to a living microorganism that causes, or may cause, human disease that may be severe and disabling Awareness Level

  26. Mechanical Hazards • Direct contact with an object • Can be mild, moderate, or severe • Striking injuries • Friction injures (1 of 2) Awareness Level

  27. Mechanical Hazards BLEVEs and other explosions can cause mechanical trauma. (2 of 2) Awareness Level

  28. Psychological Hazards • Acute stress disorder — Symptoms appear within the first 30 days and do not last more than 4 weeks • Posttraumatic stress disorder symptoms — Occur 30 days to years after the event Awareness Level

  29. Routes of Entry • Inhalation — Breathing through the nose or mouth • Ingestion — Through the mouth by means other than simple inhalation • Injection — Through a puncture or break in the skin (1 of 3) Awareness Level

  30. Routes of Entry • Absorption — Through the skin or eyes • Penetration — Radioactive particles and energy waves (2 of 3) Awareness Level

  31. Routes of Entry Chemicals often have multiple routes of entry. (3 of 3) Awareness Level

  32. Summary • Hazardous materials incidents pose significant hazards to first responders. Awareness-Level first responders must know their primary responsibilities and their limitations in dealing with hazardous materials incidents. • Hazardous materials are regulated in both the U.S. and Canada by a number of agencies. (1 of 2) Awareness Level

  33. Summary • Hazardous materials may be classified by their hazard. The NFA and NFPA have categories of hazardous materials classifications. • Hazardous materials pose significant health hazards that can range from minor to severe and even fatal. • Hazardous materials can enter the body through a number of routes.
