Methods or devices for respiratory protection
- SCBA
- SAR's(supplied air respirators)
- APR's(air purifying respirators)
- PAPR's(powered air-purifying respirators)
-
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

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
-
2 Types of liquid-splash clothing
- encapsulating
- nonencapsulating
-
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
-
Symptoms of heat stroke
- confusion
- irrational behavior
- loss of consciousness
- convulsions
- lack of sweating
- hot, dry skin
- abnormally high body temperature
