Chapter 5 Firefighter PPE Flashcards
Airborne pathogens
Disease causing microorganisms (viruses, bacteria, or fungi) that are suspended in the air
Air-purifying respirator (APR)
Respirator that removes contaminants by passing ambient air through a filter, cartridge, or canister; may have a full or partial face piece
Atmosphere-supplying respirator (ASR)
Respirator that supplies the user with an air supply from a source independent of the ambient atmosphere
Auto-cascade system
Completely automated stationary fill station that fills air cylinders to a programmed pressure
Cascade system
Three or more large, interconnected air cylinders, from which smaller SCBA cylinders are recharged; the larger cylinders typically have a capacity of 300 cubic feet (9 cubic meters)
Closed-circuit SCBA
SCBA that recycles exhaled air; removed carbon dioxide and restores compressed, chemical, or liquid oxygen. Not approved for fire fighting operations
Emergency escape breathing support system (EEBSS)
Feature installed on some SCBA which allows two firefighters to breathe from one cylinder without removing their facepieces
End of service time indicator (EOSTI)
Warning device that alerts the user that the respiratory protection equipment is about to reach its limit and that its time to exit the contaminated atmosphere; its alarm may be audible, tactile, visual, or any combination thereof
Firefighter breathing air replenishments systems (FBARS)
A standpipe for air permanently installed within a high-rise building or large horizontal structure. Air is pumped into the system by a fire departments mobile air truck on the ground, providing an immediate and continuous supply of breathing air to the responders. Air bottles can then be refilled in a matter of seconds at fill stations locates throughout a high-rise building
Fusee
Pyrotechnic flare sometimes used in wildland fire fighting to start controlled burns
High efficiency particulate air (HEPA) filter
Respiratory filter that is certified to remove at least 99.97% of mono-disperse particles of 0.3 micrometers in diameter
Hypoxia
Potentially fatal conditions caused by lack of oxygen
Oxygen-deficient atmosphere
Atmosphere containing less than the normal 19.5% oxygen. At least 16% oxygen is needed to produce flames or sustain human life
Particulate
Very small particle of solid material, such as dust, that us suspended in the atmosphere
Permissible exposure limit
How much time 95% of adults can be exposed to a chemical or work area without having long term effects
