Important Rules During Escape; End Of Use; Disposal; Transport Regulations - Dräger Oxy K 30 S Gebrauchsanweisung

Important rules during escape

— Stay calm when leaving the danger zone; do not rush.
— Plan your escape to be sure that you chose the shortest route on
your way to safe ambient air.
— Do not panic. Panic causes hasty, shallow breathing which uses
up more oxygen.
— Make sure to keep the mouthpiece firmly gripped between teeth
and lips and to keep your lips closed tight.
— Warm and dry air coming from the oxygen self-rescuer is a sign
that the unit is functioning properly. You might notice that the air
coming from the oxygen self-rescuer has a strange taste, but this
is normal and harmless.
— Take care not to waste lifesaving oxygen by damaging or
squashing the breathing bag.
— If you need to vomit, take the mouthpiece out of your mouth and
use your thumb to hold it shut. Do not vomit into the oxygen self-
rescuer.
Do not inhale again before putting the mouthpiece back into
your mouth to prevent an intake of toxic air from the
environment.

End of use

— Your will notice that the oxygen supply is depleted when the
breathing bag begins to deflate and it gets harder and harder to
breath.
— Any unit used underground must be brought to the surface.

Disposal

The oxygen self-rescuer is to be discarded after use.
Deactivating spent oxygen self-rescuer
— Keep the unit away from combustible substances (petrol, grease,
solvents etc.) at all times to prevent danger of fire!
— Wear protective goggles and gloves.
— Remove starter from the housing and discard it according to local
regulations.
— Remove KO cartridge from the housing.

— Keep dismounted KO cartridge completely immersed in water

until no more gas bubbles emerge. Use a 3 % acid, e.g. HCl, at a
1:1 ratio to neutralise the resulting solution.
— All plastic components are marked and can be sorted according
to their material characteristics for recycling.

Transport regulations

When being transported, breathing protection equipment is subject to
international transport regulations.
Breathing protection equipment is classified as:
UN 3356 "Oxygen generator, chemical" Class 5.1,
packing group II
Starters of damaged and/or opened and partially spent breathing
protection equipment must be activated before transport. After
cooling down, the breathing protection equipment has to be sealed in
a plastic bag. The unit has to be brought to the shipping department
in an approved packaging (e.g. Dräger Transport packaging
63 04 511).
The shipment is classified as:
UN 3085, Oxidizing solid, corrosive, n.o.s. (Potassium
Superoxide, Potassium Hydroxide), Class 5.1, packing group I
1)
Always activate the starter before sending opened oxygen self-rescuers!
Afterwards, please put the oxygen self-rescuer in a sealed PE bag

.
Please take special regulations into account which may apply for the
hired shipping company.

Maintenance

The user may carry out the following repair procedures by himself:
Replacing the indicator window
Use a screw driver to carefully remove the defective indicator
window.
Insert the new indicator window into the indicator housing by
applying a small amount of pressure.
Replacing the pictograph
Use a sharp-edged tool, e.g. a razor blade, to remove the
defective pictograph.
Use a degreasing agent to clean the surface.
Affix new pictograph.

Inspection and service

Inspect the unit on a daily basis (see "Daily inspection" on
page 8).
Observe inspection intervals (see "Service data" on page 11).

Oxygen generation

The oxygen required for breathing is supplied by a solid chemical
substance called potassium dioxide (KO
with the carbon dioxide (CO ) and the water vapour (H

exhaled air. These two components of the exhaled air are absorbed
by the KO and release the chemically-bound oxygen (O

KO is both O source and CO

and exhaling causes the breathing air to flow from the breathing bag
through the KO cartridge to the heat exchanger and then back

again.
A volume-controlled valve governs the volume in the breathing bag.
