Starters of damaged and/or opened and partly used breathing protective
devices must be activated before transit. After cooling down, the breathing
protective device has to be sealed in a plastic bag. The breathing protective
device has to be despatched in an approved packaging (e.g. Dräger
Transport packaging 63 04 511).

Potassium Hydroxide), Class 5.1, packing group I
Please note special regulations for shipping by airfreight.

Maintenance

The user may carry out the following repair procedures himself:
Replacing the indicator window (67 33 647)
Carefully remove the defective indicator window using a screw driver.
Insert the new indicator window into the indicator housing exerting
slight pressure.
Replacing the pictograph (63 04 598)
(for Oxy K 30 HW)
Remove the defective pictograph, e.g. with a razor blade.
Clean the surface using a degreasing agent.
Affix new pictograph.
Replacing the reflector stripes (63 04 503 and 63 01 996)
(for Oxy K 30 HW)
Remove the damaged reflector stripe, e.g. with a razor blade.
Clean the surface using a degreasing agent.
Affix new reflector stripe.

Inspection and Service

— Daily inspection (see "Daily Inspection" on page 11).
— Observe inspection intervals (see "Service Life Record" on page 15).

Oxygen Generation

The oxygen required for breathing is supplied by a solid chemical
substance, potassium dioxide (KO
(CO ) and water vapour (H O) in exhaled air. These two components of the
2 2
exhaled air are absorbed by the KO
oxygen (O ) in KO . The simplified reaction formulas are as follows:
2 2
O → 2 KOH + 3
2 KO + H / O
2 2 2
→ K
2 KOH + CO CO + H O + heat
2 2 3 2
→ K

KO is both O source and CO

between inhalation and exhalation, the breathing air flows from the
breathing bag through the KO cartridge to the heat exchanger and then
