During use

3.5.1 Important escape rules
 Start the escape calmly, do not rush.
 Plan your escape route, choose the shortest way to safe ambient air!
 Behave calmly. Short, quick breaths use more oxygen!
 Always make sure that the mouthpiece is tight between your teeth and lips
and cover the mouthpiece tightly with your lips.
 The air from the oxygen self-rescuer is warm and dry. This shows that the
oxygen self-rescuer is functioning correctly. A possible strange taste is
normal and harmless.
 Do not damage or compress the breathing bag, otherwise vital oxygen is
lost.
 In case of vomiting, remove the mouthpiece from your mouth and close it
with your thumb. Do not vomit in the oxygen self-rescuer!
In order to ensure that no harmful air is inhaled from the environment, inhale
from the oxygen self-rescuer first once the mouthpiece has been reinserted.
