8. OPERATING PRINCIPLE
When the CARBO self-rescuer lock lever is opened, starter activates
automatically, causing start of oxygen release, as well as heat and moisture.
Then the top and bottom lids should be removed and thrown aside.
Oxygen fills breathing bag and allows user to start breathing in the first
seconds after activation, before reaction of regenerative cartridge starts.
Moisture released from the starter, as well as the exhaled gas mixture,
containing CO
2
and moisture, initiate chemical reaction in the regenerative
cartridge during which CO
2
is absorbed and O
2
released.
CARBO self-rescuer uses pendulum breathing circuit. Exhaled gas passes
through the mouthpiece, heat and moisture exchanger and breathing tube
into the regenerative cartridge. In the regenerative cartridge the exhaled
gas is purified from carbon dioxide and enriched with oxygen. Then it
comes into the breathing bag. When the breathing bag is completely filled,
surplus gas is removed from breathing bag via relief valve.
When user makes an inhalation the breathing gas goes backwards: from
the breathing bag through the regenerative cartridge, breathing tube, heat
and moisture exchanger and mouthpiece to the user’s respiratory system.
At that the breathing gas passing through the regenerative cartridge is
additionally purified by removing carbon dioxide and enriched with oxygen.
Oxygen enrichment and removal of carbon dioxide from the breathing gas
in the regenerative cartridge is accompanied by heat emission.
CAUTION!
Warming of the case and inhaled gas indicates normal operation of the SCSR.
