CHAPTER 6 - PPE Flashcards
Activities required for rescue, fire suppression, and property conservation in structures, vehicles, vessels, and similar types of properties.
Structural firefighting.
Activities required for rescue, fire suppression, and property conservation at fires that produce high radiant, conductive, or convective heat; includes aircraft, hazmat transport, and storage tank fires.
Proximity firefighting.
Headgear worn by firefighters that provides protection from falling objects, side blows, elevated temperatures, and heated water.
Helmet.
Hood designed to protect firefighters ears, neck, and face from heat and debris; typically made of NOMEX, KEVLAR, or PBI and available in long and short styles.
Protective hood.
Coat worn during firefighting, rescue, and extraction operations.
Protective coat.
Trousers worn to protect the lower torso and legs during emergency operations. A.k.a. bunker/turnout pants.
Protective trousers.
Protective clothing designed to protect the hands.
Protective gloves.
Protective footwear meeting design requirements of NFPA, OSHA, and CAN/SCA. Protect foot, ankle, and lower leg.
Firefighting boots.
Device that limits noise induced hearing loss when firefighters are exposed to extremely loud environments, such as apparatus engine noise, audible warning devices, and the use of power tools.
Hearing protection.
Electronic lack of motion sensor that sounds a loud alarm when a firefighter becomes motionless. It can also be manually activated.
Personal alert safety system.
Exposure to conditions that create a hazard to the respiratory system, including products of combustion, toxic gases, and superheated or oxygen deficient atmospheres.
Respiratory hazards
Atmosphere containing less than the normal 19.5% oxygen. At least 16% oxygen is needed to produce flames or sustain human life.
Oxygen deficient atmosphere.
Potentially fatal condition caused by lack of oxygen.
Hypoxia.
Accumulation of fluid in the lungs.
Pulmonary edema.
Fatal condition caused by severe oxygen deficiency and an excess of carbon monoxide and/or other gases in the blood.
Asphyxiation.
Very small particle of solid material, such as dust, that is suspended in the atmosphere.
Particulate.
Respirator that removes contaminants by passing ambient air through a filter, cartridge, or canister; may have full or partial face piece.
Air purifying respirator.
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.
Powered air purifying respirator.
Compressible substance, with no specific volume, that tends to assume the shape of the container. Molecules move about most rapidly in this state.
Gas.
Gaseous form of a substance that is normally in a solid or liquid state at room temperature or pressure; formed by evaporation from a liquidor sublimation from a solid.
Vapor
Disease causing microorganisms (viruses, bacteria, or fungi) that are suspended in the air.
Airborne pathogens.
Respiratory filter that is certified to remove at least 99.97% of monodisperse particles of .3 micrometers in diameter.
High efficiency particulate air filter (HEPA)
SCBA that allows exhaled air to be discharged or vented into the atmosphere.
Open circuit self contained breathing apparatus.
SCBA that recycles exhaled air; removes carbon dioxide and restores compressed, Chemical or liquid oxygen. Not approved for firefighting operations.
Closed circuit self-contained breathing apparatus.
Respirator fit test that measures the wearers response to a test agent, such as irritant smoke or odorous vapor. If wearer detects the test agent, such as through smell or taste, the respirator fit is inadequate.
Qualitative fit test (QLFT)
Fit test in which instruments measure the amount of a test agent that is leaked into the respirator from the ambient atmosphere. If the leakage measures above a preset amount, the respirator fit is inadequate.
Quantitive fit test (QNFT)
Rules and regulations published by executive agencies of the US federal government. These administrative laws are just as enforceable as statutory laws which may be passed by Congress.
Code of federal regulations
Testing method that uses water under pressure to check the integrity of pressure vessels.
Hydrostatic test.
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.
Cascade system.
Legal term for the maximum amount of chemical substance or other hazard that an employee can be exposed to; typically expressed in parts per million or milligrams per cubic meter. If exposed to this concentration for an entire 40 hour work week, 95% of healthy adults would not suffer health consequences.
Permissible exposure limits (PEL)
Non-loadbearing rope that is anchored to a safe, exterior location and attached to a firefighter during search operations to act as a safety line.
Search line.
PPE is designed to protect from hazards and minimize the risk of injury and fatality. True or false?
True.
Inspecting, cleaning, and maintaining the condition of PPE is the responsibility of the shift supervisor. True or false?
False – it is our responsibility.
All cleaning of PPE is performed at the local station. True or false?
False – advanced cleaning, specialized cleaning, and contract cleaning done by trained personnel and manufacture companies.
