Chapter 3 - PPE Flashcards
The pressure vessel or vessels that are an integral part of the SCBA and that contain the breathing gas supply; can be configured as a single cylinder or other pressure vessel or as multiple cylincers or pressure vessels. (NFPA 1981)
Air Cylinder
The hose through which air flows, either within an SCBA or from an outside source to a supplied air respirator.
Air line
A respirator that removes specific air contaminants by passing ambient air through one or more air purification components (NFPA 1984)
Air-purifying respirator
A respirator that supplies the respirator user with breathing from a source independent of the ambient atmosphere and includes self-contained breathing apparatus (SCBA) and supplied air respirators (SAR). (NFPA 1981)
Atmosphere supplying respirator
The federal agency responsible for respirator fit testing, training and breathing air systems.
Canadian Standards Association (CSA)
A CA causing substance that is identified in one of the several published lists, including, but not limited to: NIOSH Pocket Guide to Chemical Hazards, Hazardous Chemicals Desk Reference, and the ACGIH 2007 TLV’s and BEI’s (NFPA 1851)
Carcinogen
A method of piping air tanks together to allow air to be supplied to the SCBA fill station using a progressive selection of tanks, each with a higher pressure level. (NFPA 1901)
Cascade System
Self-contained breathing apparatus designed to recycle the user’s exhaled air. This system removes CO2 and generates fresh O2.
Closed-circuit breathing apparatus
A device used for increasing the pressure and density of a gas (NFPA 853)
Compressor
To take off an item of clothing or equipment
Doff
To put on an item of clothing or equipment
Don
A feature that automatically provides a backup method for air to be supplied to the regulator of an SCBA if the primary passage malfunctions
Dual-path pressure reducer
A device on an SCBA that allows users to share their available air supply in an emergency situation (NFPA 1981)
EBSS Emergency Breathing Safety System
A warning device on an SCBA that alerts the user that the reserved air supply is being utilized (NFPA 1981).
End-of-service-time indicator (EOSTI)
Describes both the full face pieces that cover the nose, mouth and eyes and half face pieces that cover the nose and mouth. (NFPA 1404)
Face Piece
A protective device commonly intended to shield the wearer’s face, or portions thereof, in addition to the eyes from certain hazards, depending on the face shield type. (NFPA 1500)
Face shield
Protective head covering worn by firefighters to protect the head from falling objects, blunt trauma and heat
Fire helmet
A small, portable light carried by firefighters to improve visibility at emergency scenes; it is often powered by rechargeable batteries
Hand light
Visual display of information and system condition status that is visible to the wearer (NFPA 1981).
HUD - Heads up display
A test performed by filling pressure-containing components completely with water or other incompressible fluid while expelling all contained air, closing or capping all open ports of the pressure-containing components to a prescribed value through an externally supplied pressure-generating device to verify its strength against unwanted rupture (NFPA 1901 and 10)
Hydrostatic testing
Any condition that would pose an immediate or delayed threat to life, cause irreversible adverse health effects, or interfere with and individual’s ability to escape unaided from a hazardous environment (NFPA 1670)
Immediately dangerous to life and health
Electronic semiconductors that emit a single-colour light when activated. They are used for operational displays in SCBA
LED’s/Light emitting diodes
The US federal agency responsible for research and development on occupational safety and health issues.
NIOSH
An insert inside the facepiece of an SCBA that fits over the user’s mouth and nose
Nose cups
