|
what are the most effective methods of protecting personnel against such contaminants. |
Engineering Controls, i.e, exaust ventillation |
|
|
Who appoint a respiratory protection manager (RPM) in writing |
CO |
|
|
The Resp Prot Mngr: is req to complete training w/in __months of assumingthe position |
3 months |
|
|
Name the two types of respirators |
1. air-purifying 2. atmosphere-supplying |
|
|
which respirator works by remove air contaminants by filtering, or by absorbing them as the air passes through the cartridge |
Air purifying respirator |
|
|
when using an air pur respr, how much oxygen must be present by volume |
19.5% |
|
|
The non-powered _____resp depends on the user's lungs to draw air through the purifying element during inhalation; therefore, the non-powered type has the greatest breathing resistance. |
air purifier |
|
|
air-purifying respirators may be subdivided by the type of contaminant they protect against. Name the three types. |
1. Particulate air purifying resp (protects against inhaling aerosols) 2. Gas and Vapor Air purifying resp 3. Combination cartridge and canisters 9combo of the other two) |
|
|
How many classes of non-powered particulate air-purifying resp., and name the three filter classes |
-9 - N-; R-; P- classes( ea class has 3 levels of efficiency: 95%, 99% and 99.97%) |
|
|
Taking the 3 classes of Particulate air respr, these 3 filters are equivalent to high efficiency particulate air (HEPA) filters. |
N100; P100; R100 |
|
|
P-class filter use__ aerosols and are the only MAGENTA (purple) colored high efficiency filters |
oil |
|
|
This class filter can only be used for a single shft in oilaerosols |
R100 |
|
|
T/F: Surgical masks (blue or green) do not provide protection against air contaminants. They are for MEDICAL/DENTAL USE ONLY and must NEVER be used as an airpurifying respirator. |
True |
|
|
This type of respirator uses cartridges and canisters that remove contaminants through absorption and adsorption. Typically, a cartridge removes a specific type or class of gas or vapor |
Gas and Air purifying respirator |
|
|
What is each canister/cartridge labeled with |
*Each cartridge/canister is labeled with the contaminant(s) it protects against
*the NIOSH approval number. |
|
|
The MCU-2A/P; Mark V and the M40 are 3 types of ___gas masks used specifically for CBR attack |
Military |
|
|
Atmosphere-supplying respirators are used when.. |
1. no warning properties like eye, skin irritation 2. % is too high for use of an air purifying resp 3. environment is immediately dangerous to life or health |
|
|
Name the two types of atmospheric suppl resp? |
1. SCBA 2. Supplied air (airline) resp |
|
|
There are 3 types of air-line respirators: |
1. demand 2. pressue demand 3. continuous flow |
|
|
T/F: The SCBA is considered a open- circuit rebreathing device? |
F: it is closed circuit |
|
|
What is the difference between the two types of SCBA's? |
Its use of oxygen: Type 1: oxygen prov by either high-pressure gaseous oxygen or gaseous oxygen converted from liquid oxygen. Type 2: water vapor in the exhaled breath reacts w/ a chemical in the canister to release oxygen (ex: OBA but its not appr by NIOSH) |
|
|
For an air-line resp., the maximum length of hose allowed from a compressor or air fitting to the respirator shall be___feet unless a shorter maximum length is specified on the NIOSH approval. |
300 ft |
|
|
When and where is an OBA (oxygen breathing apparatus) authorized for use? |
authorized uses aboard ship are for damage control, fire-fighting operations, and fixed flooding systems PMS |
|
|
What type of SCBA is only used for ESCAPE AND NEVER FOR ENTRY TO A HAZARD OUS AREA? |
EEBS (emer escape breathing device) |
|
|
When is a SEED (supplimental emer escape device) used |
it is used for escape only for MAIN PROPULSION SPACE WATCHSTANDERS ONLY |
|
|
Who is responsible for approving all respirators and their certification? |
NIOSH |
|
|
All respirators will be inspected atfter each use and at least every |
month |
|
|
When cleaning the respirators, which parts are thrown away? |
all used cartridges and filters |
|
|
What will you use to wash the face piece and parts?
|
WARM water and a mild dishwashing detergent solution. DO NOT EXCEED TEMPS OF 43C (110F) |
|
|
After washing the facepiece, how is the face piece sanitized? |
1. immerse for 2 MINUTES in warm H2O soln of bleach @ 1ml blch:1L h2o OR immerse 2 MINUTES in warm H2O and soln of iodine (0.8 ml of tincture: 1L H2O) OR immerse in warm H2O for 2 MIN of approved commercially avail cleansers of equiv disinfectant quality when used as directed 2. Rinse clean w/ warm H2O 3. Dry in are under 43 deg C 4. Place in ziplock bag DRY
|
|
|
Breathing air or the air output of pumps or compressors which are sources of breathing air for airline respirators or SCBAs shall meet at least the minimum of grade __air usage |
Grade D |
|
|
The air output of compressors used by breathing air shall be tested____. |
Quarterly |
|
|
What exam is performed on a service mbr when IMR status is unknown for resp certification purposes? |
