4.4 Breathing mask
Put on breathing mask
1. Adjust the forehead support of the breathing mask (if provided).
2. Connect the headgear/headband to the mask.
3. Put on the mask.
4. Adjust the headgear/headband so that the bulge of the mask creates only low pressure
so as to prevent pressure points on the face.
Note:
Consult the instructions for use for the breathing mask in question for information
on how to proceed.
Warning!
Full-face masks must be equipped with an emergency exhalation valve so that you
can breathe through nose or mouth in the event of any device failure. Full-face masks
without an emergency exhalation valve may not be used!
External exhalation system
No exhalation system is integrated in some masks. In order for the used, carbon dioxide
(CO
2
)-enriched air to be able to escape, an external exhalation system is required on these
masks. Follow the instructions for use for the mask.
Warning!
Without an exhalation system, the CO
2
concentration would rise to critical levels in
the mask and tube and thus inhibit your breathing. Risk of suffocation!
– Fit the external exhalation system between the
breathing mask and the breathing tube.
