M-20 SELF-CONTAINED SELF-RESCUER
Oxygen flow begins when the M-20 is pulled from its
case. Oxygen is inhaled through the mouthpiece from
the breathing bag. Breath is exhaled through the
mouthpiece into the CO2 scrubber. Scrubbed breath
enters the breathing bag and is mixed with oxygen from
the oxygen cylinder.
