Abstract

A method for cleaning a breathing apparatus comprising a respiratory mask, by such precleaning activity as: providing the breathing apparatus in an externally contaminated state, providing a holder for the respiratory mask having at least one curved sealing face and stretching the respiratory mask onto the holder such that a sealing lip of the respiratory mask lies on the curved sealing face and closes off an interior of the respiratory mask, and the holder with the respiratory mask may be introduced into a precleaning chamber, exposing an outer side of the respiratory mask in the precleaning chamber to at least one precleaning fluid. And, after the precleaning, the respiratory mask may be released from the holder, introducing the respiratory mask into a primary cleaning chamber and exposing the respiratory mask, including an inner side of the respiratory mask that faces the interior, to a primary cleaning fluid.
