Donning Procedure

If the oxygen self-rescuer is not donned correctly, there could be a delay in
starting in an emergency.
Perform the following donning steps according to the described
order.
Opening the container
Pull the lever up with forefinger or
thumb as far as it will go until the
fixing straps loosen.
Remove lid.
Pulling the oxygen self-rescurer out
Get hold of the red loop on the
exposed part and pull the oxygen
self-rescuer out of the housing
smoothly in one go; doing so will
automatically activate the starter
cartridge and the yellow breathing
bag will fill with oxygen after about
6 seconds. The loose packaging
will fall off or may be removed.
CAUTION!
The activated starter will
become hot!
Do not touch, danger of burning!
Support unfolding of the breathing bag with your hands.
Quickly perform the following donning steps within approx.
20 seconds.
Preparing and inserting the mouthpiece
Remove the mouthpiece plug from
the mouthpiece.
Hold the oxygen self-rescuer with
the breathing bag pointing away
from your body.
Put mouthpiece in your mouth
and exhale vigorously into the
gen self-rescuer .
The rubber gum plate must be
inserted between your teeth and
lips
.
WARNING
The mouthpiece is of limited use for
persons wearing dentures.
Tightly seal round the mouthpiece
with your lips.

Fitting the nose clip
Pull the nose clip apart and fit over
your nostrils so that your nose is
completely sealed.
If the breathing bag has not yet inflated
Exhale several times to fill the breathing bag. The humidity and CO
content in the exhaled air will start the oxygen production.
Breathe steadily.
Fitting and tightening head straps
Take off your helmet.
Untangle headstraps and pull over
head.
Pull the red ends of the band evenly
towards the headstraps until tight.
Put your helmet on again.
Note
Dräger suggests to practice this procedure with the training unit.

Important Rules for Escaping

— Begin your escape calmly; do not rush.
— Plan your escape so that you use the shortest route to safety.
— Behave calmly. Hurrying makes you breathe more quickly and uses up
more oxygen.
— Make sure that the mouthpiece is gripped firmly between the teeth and
lips and is completely sealed by the lips.
— If the air from the oxygen self-rescuer is warm and dry, this is a sign that
the oxygen self-rescuer is functioning correctly.
Any off-taste is quite normal and not dangerous.
— Take care not to damage or squash the breathing bag and so waste life-
saving oxygen.
— If you have to vomit, take the mouthpiece out of your mouth but keep it
sealed with the thumb. Do not vomit into the oxygen self-rescuer.
Do not start to inhale again until you have put the mouthpiece back
into your mouth so that you do not inhale toxic substances from the
ambient air.

End of Use

— When breathing becomes more difficult and the breathing bag begins
to deflate, the oxygen supply is coming to an end.
— Any oxygen self-rescuer used underground must be brought to the
surface.
