Study Notes
Hazards of Fighting Fires
- The human respiratory system is sensitive and delicate, making it vulnerable to injury from smoke, gases, and other hazards.
- Standard Operating Procedures require the use of Self-Contained Breathing Apparatus (SCBA) in hazardous atmospheres.
Hazardous Atmospheres
- An atmosphere is considered hazardous if it contains:
- High heat
- Smoke
- Toxic gases
- Oxygen deficiency
- Suspected hazardous material release
- Modern buildings may release toxic chemicals when they burn, increasing the risk of inhalation hazards.
SCBA Components
- Pressure reducer:
- Incorporates an intermediate pressure relief valve
- Has a cylinder connector with a sintered filter to capture particulates
- Connects to the cylinder via a Quick Connect fitting
- Power module:
- Serves as the power supply and provides information for the control module, regulator, and speaker module
- Connected to the backplate
- Emits audible PASS alarms and pre-alarms
- Has 4 buddy lights
- Contains non-replaceable lithium-ion cells
- Notifies the user when batteries need to be recharged
- G1 Control Module:
- The user's interface with the SCBA and PASS device
- Assembled to the high-pressure air source and power module
- Equipped with an analog gauge and graphical display
- Provides vital information: time remain, cylinder pressure, battery status, and alarms
SCBA Operation
- The PASS device performs a self-test during startup to ensure correct operation
- The primary screen displays critical information, including calculated remaining service time
- The secondary screen displays additional information, including temperature gauge, Bluetooth connectivity, and battery status
- The HUD provides pressure and alarm status through light pipes into the facepiece
SCBA Inspection and Maintenance
- The District requires daily inspection of SCBA as part of the daily check-off
- Inspectors should check for:
- Deterioration, dirt, cracks, debris, tears, holes, or other visible signs of damage
- Functionality of all components
- Facepiece inspection, including lens, rubber, and exhalation valve
- Regulator inspection, including o-ring and seal ring
- Pressure reducer inspection, including quick connect hose and fittings
- SCBA that fail any inspection condition should be removed from service
