View of the dirty, north side of the three disinfection autoclaves supplied by a München manufacturer and numbered from right to left 1, 2, 3. They are built into the wall separating the clean and dirty sides and have a door on each side.

Autoclave 2 seen from the dirty side. In this photo we see through the autoclave to the other side. Dirty clothes were put on hangers on a trolley which was pulled towards the north and put on two short rails. Once the action of the steam was completed, the operator on the clean side opened the door pulled out the trolley and removed the “sterilized” clothes.

Present view of the north side doors of autoclaves 2 and 1. The dirty side doors were rarely if ever photographed during the war because they are on the north side when there was rarely much light. Photo
