  1. Methods or devices for respiratory protection
    • SCBA
    • SAR's(supplied air respirators)
    • APR's(air purifying respirators)
    • PAPR's(powered air-purifying respirators)
  2. NFPA 1994 PPE classes (3); describe them
    • Class 2- intended for use at a terrorism incident involving vapor or liquid with concentrations above IDLH; requires SCBA
    • Class 3-Low levels of vapor or liquid concentrates below IDLH; Permits use of APR or PAPR
    • Class 4-intended for use at biological or radiological particulate hazard concentrations below IDLH; permits use of APR or PAPR; ensembles are not tested for protection against chemical vapor or liquid permeability, gas-tightness, or liquid integrity
  3. How many types of High temperature protective clothing suits are there?
    Describe them
    • 2
    • Proximity suits- Permit close approach to fires for rescue, fire-suppression, and property conservation activities such as in aircraft rescue and firefighting or other firefighting operations involving flammable liquids
    • Fire-entry suits-allow a person to work in total flame environments for short periods of time; provide short duration and close proximity protection at radiant heat protection as high as 2,000F. Each has a specific use and is not interchangeable; not designed for chemical protection
  4. 2 Types of liquid-splash clothing
    • encapsulating
    • nonencapsulating
  5. Describe the 4 US EPA levels of protection
    • Level A-Provides the highest level of protection against vapors, gases, mists, and particles for the respiratory tract, eyes and skin; requires SCBA and totally encapsulating chemical protective suits(TECP) inner and outer gloves and chemical resistant boots
    • Level B-This ensemble is worn when the highest level of respiratory protection is necessary but a lesser level of skin protection is needed; Consists of SCBA, liquid splash protective chemical suit, inner and outer gloves, chem resistant boots
    • Level C- Emergency response personnel would not use this unless the specific material is known; affords lesser level of respiratory and skin protection. Full face or half mask APR, hooded chemical suit, inner+outer gloves and chem resistant boots
    • Level D- commonly consist of work uniforms
  6. Symptoms of heat stroke
    • confusion
    • irrational behavior
    • loss of consciousness
    • convulsions
    • lack of sweating
    • hot, dry skin
    • abnormally high body temperature
