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
PASS DEVICE
(Personal Alert Safety System)
Electronic lack-of-motion sensor that sounds a loud alarm when a firefighter becomes motionless; can also be manually activated
PPE
General term for the equipment worn by fire and emergency service responders
Point of no return
Point at which air in the SCBA will last only long enough to exit a hazardous atmosphere
Powered air-purifying-respirator (PAPR)
Motorized respirator that uses a filter to clean surrounding air, then delivers it to the wearer to breathe; typically includes a headpiece, breathing tube, and a blower/battery box that is worn on the belt
Protective coat
Coat worn during fire fighting, rescue, and extraction operations
Protective gloves
Protective clothing designed to protect the hands
Protective hood
Hood to protect a firefighters ears,neck, and face from heat and debris
Protective trousers
Trousers to protect the lower torso and the legs during emergency operations
Proximity fire fighting
Activities required for rescue, fire suppression, and property conservation at fires that produce high radiant, conducive, or convective heat; includes aircraft, hazardous materials transport, and storage tank fires
Pulmonary edema
Accumulation of fluids in the lungs
-from breathing in hot gasses
Qualitative fit test (QLFT)
Respirator fit test to measure the wearer’s response to a test agent, such as smoke or odorous vapor, if the wearer smells or tastes it the respirator doesnt fit
Quantitative fit test (QNFT)
Fit test in which it measures the amount of a test agent that has leaked into the respirator from the ambient atmosphere, if it leaks above the pre set amount the mask does not fit
Remote pressure gauge
Pressure gauge that is not mounted on the regulator but can be seen by the SCBA wearer; commonly found on SCBA that have facepiece mounted regulators
Respiratory hazards
Conditions that create a hazard to the respiratory system, including products id combustion, toxic gasses and superheated or oxygen deficient atmospheres
Retroreflective trim
Surfaces such as those used on road signs, and emergency vehicle markings, protective clothing, or safety vests; designed to reflect light along multiple planes at once, giving the surface the appearance of illumination
Search line
Non-load-barring rope that is anchored to a safe, exterior location and attached to a firefighter during search operations to act as a safety line
Self contained breathing apparatus (SCBA)
Respirator worn by the user that supplies a breathable atmosphere that is either carried in or generated by the apparatus and is independent of the ambient atmosphere, all IDLH situations respirator protection is required
Structural firefighters protective clothing
General term for the equipment worn by fire and emergency services responders; includes, helmets, coats, pants, boots, eye protection, gloves, protection hoods, SCBA, and a PASS device
Thermal saturation
Point at which a liquid or solid can no longer absorb heat without undergoing a physical change, wither vaporization in liquids or pyrolization in solids
