18
Q

advance cleaning

A

those personnel should use a washing machine dedicated to cleaning protective clothing that is designed to handle heavy loads

19
Q

specialized cleaning

A

is required when clothing is contaminated with hazardous materials or body fluid that cannot be removed by routine or advance cleaning

20
Q

contract cleaning

A

typically removes accumulated grime or contaminants

21
Q

two types of respiratory protection equipment

A

atmospheric-supplying respirators (ASRs)
Air-Purifying respirators (APRs)

22
Q

respiratory hazards

A

oxygen deficiency
elevated temperatures
particulate contaminates
gases and vapors
airborne pathogens

23
Q

oxygen deficiency

A

atmosphere containing less than 19.5% oxygen

combustion is the most common cause of oxygen-deficiency atmospheres
- it consumes oxygen and produces toxic gases, which typically displaces oxygen or dilute its concentration

24
Q

elevated temperatures

A

excessive heat inhaled quickly into the lungs can cause serious decrease in BP and failure of the circulatory system

inhaling heated gases can cause pulmonary edema which can cause asphyxiation

25
Q

Particulate Contaminants

A

small particles that may be suspended in the air and are harmful to the respiratory system

sources of these particulates include
- vehicle exhaust
- chemical reactions
- heated metals or metal compounds
- combustion

26
Q

gases and vapors

A

gases exist at standard temperatures and pressure

vapors result from temperature or pressure changes that affect a solid or liquid

27
Q

Airborne pathogens

A

are disease-causing micro-organisms suspended in the air, cause infection through inhalation or direct contact

28
Q

open-circuit SCBA

A

uses compressed air

Exhaled air is vented to the outside atmosphere

29
Q

qualitative fit test (QLFT) + Quantitative fit test (QNFT)

A

provide an adequate assessment of a facepiece ability to maintain a complete seal to the face

30
Q

closed-circuit SCBA

A

uses compressed oxygen

exhaled air stays within the system for reuse

31
Q

End-of-service-time-indicator (EOSTI)

A

require two alarms must be installed on all SCBAs

alarm warns the user that the system is reaching the end of its air supply, typically when it reaches 33 percent of the cylinders capacity

32
Q

SCBA Wearer limitations

A

lack of physical condition
lack of agility
impaired balance
inadequate pulmonary capacity
weakened cardiovascular ability
psychological limitations
unique facial features

33
Q

SCBA equipment limitations

A

limited visibility
decreased ability to communicate
decreased endurance
decreased mobility
poor condition of apparatus
low air cylinder pressure

34
Q

SCBA donning methods

A

over-the-head
coat method
donning from a seat
donning from side/rear external mount

35
Q

your SCBA requires ongoing inspections and maintenance to protect you properly, you mist clean and inspect it:

A

after each use
at the start of every duty shift
every week

36
Q

three breathing air sources to refill depleted SCBA cylinders

A

stationary fill stations

mobile fill stations

firefighting breathing air replenishment system (FBARS) - system installed in high-rise buildings

37
Q

stationary fill stations

A

cascade system

auto-cascade system

38
Q

storing respiratory protection equipment

A

stored for quick and easy donning

protect from contamination, temperature changes and ultraviolet light

39
Q

Exit indicators

A

situations or events that signal the need to exit

40
Q

Permissible Exposure Limit (PEL)

A

the IC issues orders to change the required level of respiratory protection or withdraw from the area completely

41
Q

buddy system

A

each team member is responsible for the safety of the other member

the only time a member may work alone is in a confined space where two members cannot fit
(second team member remains outside monitoring the search line, ready to enter the space if need be)

42
Q

Controlled breathing

A

inhale naturally through the nose then forcefully exhale through the mouth, reducing air consumption

43
Q

Reilly emergency breathing method

A

involves inhaling deeply through the nostrils, fill lungs fully then hum while exhaling

44
Q

egress paths

A

when you exit an IDLH area, it is important to use the same path that you used to enter

you should also be aware of other means of egress in case your entry route is blocked
