What are the two basic types of respirators?
air purifying
atmosphere supplying
What type of respirator removes air contaminants by filtering, or absorbing them as the air passes through the cartridge?
Air-purifying
What is the acronym PAPRs?
powered air purifying respirator
What are the two types of air-purifying respirators?
Powered and non-powered
How many classifications of non-powered air purifying respirators are there?
nine (3 filter classes with 3 levels of filter efficicnecy)
what are the three filter classes for non-powered respirators?
N
R
P
What class series of non-powered air-purifying respirator can be used in oil aerosols?
P - Class
What color are P-class air purifying respirator filters?
magenta (purple)
What class series of non-powered air purifying respirator can be used only for a single shift in oil aerosols?
R - class ( N- class cannot be used at all)
What color are powered air purifying respirator HEPA filters?
Magenta
When are atmosphere-supplying respirators used?
contaminate has no warning property
concentration is to high for air-purifying filter
immediately dangerous to life or health (IDLH)
What are the two types of atmosphere supplying respirators?
Supplied air (air-line) Self-contained breathing apparatuses
What are supplied air respirators further subdivided into?
hose mask and air-line respirators
What is the maximum length of hose allowed from the compressor or air fitting device to the respirator in air-line respirators?
300 feet
What are the two categories of self contained breathing apparatuses?
Closed circuit
Open circuit
What is the special type of SCBA developed by the Navy specifically for emergency escape from shipboard fires?
Emergency Escape Breathing Device (EEBD)
What are some contaminates that do not have warning properties?
carbon monoxide
hydrogen cyanide
isocyanates
methyl alcohol
What is the abbreviation APF?
Assigned Protection Factor
What percentage defines sufficient oxygen?
19.5
How often are personnel that require respirators fit tested?
before being issued a respirator and annually thereafter
What type of fit testing is performed by using irritant smoke, isoamyl acetate, sacchairin mist, or Bitrex?
Qualitative fit testing
How often are emergency respirators inspected?
after each use and at least monthly
How long are emergency respirator inspection records maintained?
for the life of the respirator
When entering into an area immediately dangerous to life or health with a pressure demand air-line respirator, what is the minimum auxiliary self contained air supply that needs to be equipped?
15 minutes worth
Who appoints a respiratory protection manager (RPM) in writing?
CO
Within how many months of assuming the position, will the RPM attend the respiratory protection program management course?
3 months
What is another special type of SCBA developed for main propulsion space watchstanders only?
SEED, Supplemental Emergency Escape Device
Who is the sole certification agency for Respirators?
NIOSH - National Institute for Occupational Safety and Health
What is the abbreviation ESLI?
End of service life indicator
Where should ESLI indicator cartridges be worn?
on belt or chest mounted so they can be seen, newer respirators have them on upper edges of cartridges so they can be seen be wearer.
What type of fit-testing can only be done by shore activities?
Quantitative fit testing
