Q

What is vapor?

A

Gaseous state of substance that is normally liquid at room temp.

20
Q

What are engineering controls?

A

Vent systems
- can be used in NBC/CBR environments
Exhaust
- Forced air supply, damage control gear

21
Q

What is the CO’s responsibility for gas free medical surveillance and Physical exam?

A
  • Adequately staffed with trained personnel

- Ensure all personnel comply with program req’s

22
Q

Safety officer role with Gas free med surveillance

A

Evaluate program annually

23
Q

Medical dept Rep for gas free medical surveillance/physical exam?

A
  • Advise GFE if there is a victim, proper aid once victim is removed
  • monitor victim use of EBA/equipment and advise of replacement
24
Q

What are the three basic types of respirators?

A
  • air purifying
  • atmosphere supplied air
  • SCBA
25
Q

Air purifying respirators do what?

A
  • Remove contaminants through filter/absorption
  • adequate O2 @ 19.5%
  • Full face respirator = higher degree of protection
26
Q

DO surgical masks provide protection against air contaminants?

A

NO, only for medical/dental use

- never use them for an air purifying respirator

27
Q

Should military gas masks be used in place of air purifying filters?

A

No, dumbass they are for CBR

28
Q

Should military gas masks be used in place of air purifying filters?

A

No, dumbass they are for CBR

29
Q

What are the two types of categories for air purifying respirators?

A
  • Particulate air-purifying respirator - uses cartridges, filters, pre-filters against aerosols
  • Gas and vapor air-purifying respirator - uses cartridges/canisters for adsorption/absorption
30
Q

WHat are combination cartridges and canisters?

A

Combine the removal capabilities of two or more types in one

31
Q

Pre-filters do what?

A

Protect against aerosols with volatile solvent

- another level of protection

32
Q

What does an atmosphere-supplying respirator do?

A
  • Protects users by supplying O2 for maintenance of life
  • used when contaminant has no warning property
  • high concentrations of contaminant
  • * Environment is immediately dangerous to life or health (IDLH)*
33
Q

WHat are the two types of supplied-air respirators?

A

Hose mask respirator

Air-line respirator

34
Q

Hose mask respirator does what?

A

air supplied by blower, being removed by fleet because is offers no advantage over counterpart

35
Q

Air-line respirator and SCBA’s have three categories, what are they?

A

Demand, pressure demand, and continuous flow

36
Q

Demand respirator benefits?

A
  • Air on demand

- Negative pressure within face piece

37
Q

Pressure demand benefits?

A
  • Maintains continuous positive pressure

- prevents contaminant leakage into mask

38
Q

Continuous flow benefits?

A
  • Face piece, helmet, hood, or suit
  • provides continuous flow of air
  • Prevents inward contamination
39
Q

CLosed circuit SCBA types?

A
  1. O2 provided by HP O2 or liquid O2
  2. Water vapor exhaled to demand O2 from canister
    * ** do not use where flammableareas, canister generates heat***

Open circuit SCBA
- air expelled into atmosphere

40
Q

Open circuit SCBA uses?

A
  • Demand
  • Pressure demand
  • Emergency escape devices
  • Emergency escape breathing device (EEBD)
41
Q

** EEBD uses? **

A
  • developed for confined spaces in the Navy

- short duration of use for escape NOT ENTRY INTO SPACES

42
Q

Cleaning/Sanitizing respirators???

A
  • Temps above 110 F avoid
  • 2 minutes in 50ppm solution of Iodine
  • rinse with warm water about 100 F
  • air dry in uncontaminated clean room
43
Q

Storage or respirators?

A
  • Place in clean bag with seal
  • Ensure completely dry prior
  • Store flat, without crowding so face-piece is not deformed
44
Q

Fitting of respirators?

A
  • Quantitative fit test prior to issue, then annually.

- Wear full ppe during fit to determine obstructions

45
Q

Authorized Fit Testers?

A

Persons trained as per Chapter B0612

46
Q

Qualitative Fit Testing?

A
  • * Isoamyl acetate*
  • Saccharin mist
  • irritant smoke
  • ** can only be performed on shore testing. ***
47
Q
