Parts of SCBA System Air cylinder Regulator Backpack frame Facepiece PASS Alarm
Maintenance of the SCBA System The five components of the system combine to allow a firefighter to safely operate in a dangerous environment. Proper maintenance of all parts is required to ensure the system does not fail.
Air Cylinder Visual inspection of the cylinder, gauge, and valve to check for damage, dents, cracks or other anomalies. Check the cylinder to ensure it has at least 4000 psi. If below, have the cylinder filled. Prior to filling, check the hydrostatic test date to ensure within limits. All cylinders we have must be hydrostatically tested every three years.
Regulator Takes the high pressure air of the cylinder, and steps it down to a usable pressure. 1 st stage or pressure reducer connected to backpack frame, and is not serviceable by field level technician. 2 nd stage mounts to the face piece.
Regulator High pressure and low pressure hoses can be checked for nicks, cuts, or abrasions that could cause failure. Check “O” ring at cylinder connection. Hose connections can be checked for air leaks.
Regulator Leaking or damaged hoses or “O” rings can be serviced by field level technician Minor repairs can be done to regulator, ie: replace gaskets, springs, diaphragm
Backpack Frame Provides the mounting platform to hold the air cylinder in place, and attachment for pressure reducing and regulator assembly, and remote pressure gauge. Shoulder and waist straps allow the system to be carried comfortably on the body Two styles – wire frame model, and solid aluminum frame contoured to wearers back
Backpack Frame All straps should be checked for cuts or abrasions that could result in failure Heavily worn or damaged straps should be replaced Frame should be inspected for broken welds, and worn or broken mounting hardware
Facepiece Protects the wearer from exposure to heat, toxic gases, and unburned products of combustion Allows the wearer to see in a smoke filled environment In conjunction with the regulator, provides a source of fresh air
Facepiece Examine face piece for cracks or scratches that could cause failure, especially around the regulator mount Check temple and neck straps for excessive wear, or loss of elasticity. If worn, or no stretch in them, have them replaced
Facepiece Check skirt of mask to ensure no cuts or tears that could cause failure Check nose cup and inhalation check valves Check voice amplifier for operation After use, clean by spraying disinfectant on the interior and wait at least 10 minutes before wiping the mask dry
PASS Alarm Audible warning device that signals for assistance when a fire fighter goes down or becomes incapacitated. Should always be activated BEFORE entering an IDLH environment. Operation should be tested weekly and battery replaced at regular interval.
Field Function Test of Air Pack Ensure that the unit is clean – no loose debris, system wiped down to clean off any debris or unburned products of combustion Turn on air cylinder – ensure pressure at cylinder gauge and remote gauge is equal or fairly close – if big difference tag and take out of service Listen for activation of low air warning system
Field Function Test of Air Pack Attach mask to regulator Place mask on face and inhale to start air flow, ensuring smooth air flow in system Check purge valve to ensure proper operation Turn off air cylinder and bleed down system – listen for activation of low air warning system Activate donning switch
Field Function Test of Air Pack Extend all straps. Check PASS alarm for proper function. Extend straps on face piece. Check voice amplifier for operation. Bag face piece to keep it clean and dust free. Log inspection in the SCBA log book.
Fill Station Instructor will teach/demonstrate how to fill SCBA Bottles from: Station 1 Fill Station Rescue 81 Instructor will teach/demonstrate how to fill storage bottles on Rescue 81
Cleaning / Sanitizing Procedures for cleaning/sanitizing face masks after use: Mask will be washed under clean water to remove excess debris Mask sanitizer wipes will be used on all rubber portions of the mask Face shield will be wiped with alcohol wipe Mask will be dried and placed back on apparatus
Practical Exercise Firefighter shall: Demonstrate the following emergency techniques using the SCBA to: Assist other firefighters with turning on and off SCBA Conserve Air Skip breathing, etc… Show restrictions in use of by-pass valve Breathing from the breather tube or regulator in the event of a face piece failure
