hazardous materials hazards
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

hazardous materials behavior
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

thermal hazards cold temperatures
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

thermal hazards elevated temperatures
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

radiological hazards
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

asphyxiation hazards
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

chemical hazards
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

chemical hazards1
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

etiological hazards
Etiological Hazards
  • Exposure to a living microorganism that causes, or may cause, human disease that may be severe and disabling

Awareness Level

mechanical hazards
Mechanical Hazards
  • Direct contact with an object
    • Can be mild, moderate, or severe
    • Striking injuries
    • Friction injures

(1 of 2)

Awareness Level

mechanical hazards1

psychological hazards
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

routes of entry
Routes of Entry
  • Inhalation — Breathing through the nose or mouth
  • Ingestion — Through the mouth by means other than simple inhalation

summary
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

summary1
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.
