airflow is interrupted or fails. It consists of two
lightweight escape cylinders, a full facepiece with a
mask-mounted pressure demand regulator, a first stage
regulator, an alarm, and other associated components. A
harness and carry pouch is provided to carry and protect
the cylinders. The SCBA provides an emergency air
supply of 15 minutes. Proper techniques to don and
remove the SCBA will vary slightly due to different
styles of SCBA, and you will learn and practice these
techniques either aboard ship or at a Fleet Training
Center, during fire-fighting team trainer evolutions.
WARNING
Properly performed scheduled
maintenance is essential to safe, dependable
operation of the supplied air respirator (SAR)
with the self-contained breathing apparatus
(SCBA). Omission or lax performance of
prescribed maintenance procedures could
result in equipment failure, injury, or death to
personnel.
Cleaning, inspections, and scheduled maintenance
of the SAR/SCBA is vital for personnel safety and
must be completed according to scheduled PMS and
the manufacturer's technical manual.
