5.3 Replace the exhalation filter (green)
1. There is no alarm for a blocked exhalation filter, however should it be difficult to
exhale, check;
› The exhalation filter (green) is blocked and a major leak occurred due to
overpressure in the mask
2. In that case, the user has to leave the environment with the hazardous mixture
and move either self or with aid to an environment that is considered as safe.
3. In a safe environment, evaluate what caused the alarm.
If a leak is not determined as cause for the exhalation resistance perform the
procedure to replace the exhalation filter (green):
If a leak is determined as cause for the alarm, two (2) possibilities occur:
a. The leak is caused by a mechanical reason to the mask (breech, facial hair,
other) to the mask
b. The leak is caused because the exhalation filter is clogged
4. If the leak can not be determined to a mechanical breech and hence the
exhalation filter (green) is clogged, perform the below procedure to replace the
