ABSTRACT:
A breathing apparatus removably mounted in a housing has a device for processing the breathing gas. This device includes a container and a charge for processing the breathing air which is disposed in the container. The container has air pass-through openings at least one of which is closable with a stopper. The breathing apparatus provides an indication of possible entry of water vapor and this indication is limited to only the water-vapor sensitive parts of the breathing apparatus. For this purpose, a charge is provided in the stopper having a moisture-sensitive indicator which is visible through a viewing window from outside the housing and this charge is in gas contact with the charge of the device for processing the breathing gas.
