East and north sides (center and right respectively) of the former building 164 of Kanada I, the south-east end having no roof. Photo taken during the 1950’s when the house was once more inhabited.

East side of the former building 164 where during the war there was a gas chamber using Zyklon-B for delousing clothing On the extreme right, rather faint, but stilil legible, the number 164. Behind the tree there is a window, once more in its initial position, having been blocked up during the war, where one of the extractor fans was installed. To the left the gas-tight door with another ventilation hole. The electrical control box for the fan has been removed (cf. Photo 13).

Exterior of the gas-tight door, still as it looked in January 1945 (cf. Photo 14).

View of the interior of the gas-tight door, still with the remains of the strips of felt that were nailed to the edges of the door and the frame to make it gas-tight. The inside of the peephole IS NOT protected by a hemispherical grid (as on Photo 30 [32] page 50). Furthermore, the nuts of the bolts holding the metal bars ARE ON THE INSIDE, UNLIKE those of the shutters through which the Zyklon-B was introduced in the homicidal gas chambers of Krematorium IV and V at Birkenau (see Part II, Chapter7).

Interior of the gas-tight door, closed, photographed from inside the former gas chamber on a south-north line. It is likely that the dark patches on the wall to the right of the door are bluish, a characteristic sign of the prolonged use of the room for gaseous delousing using hydrocyanic acid, the main component in Zyklon-B.
Photo 27: [PMO neg. no. 10093]

View of the emplacement of a third extractor fan, position unknown, probably in the southeast wall behind the building, taken from inside the gas chamber. The dark marks around the ventilator are probably the bluish traces of hydrocyanic acid.

Photos 28 to 31 demonstrate the practical impossibility, without further information, of distinguishing between gas-tight doors coming from homicidal gas chambers and those from disinfestation gas chambers. of the same model, they were all made in. the metal working and carpentry shops of the Auschwitz DAW ["Deutsche Ausrüstungswerke / German equipment works.]”

Warsaw Central Commission Archives, sygn.10]

Gas chamber door produced as evidence of the existence of homicidal gas chambers by the LICRA lawyers during the “Faurisson” trial. Exhibit furnished by the archives of the Warsaw Central Commission for the investigation of Hitlerite crimes in Poland. Instruction “Giftige Gase! Bei Betretendes Raumes LEBENSGFFAHRT / Toxic gases! DANGER on entering this room.” This is not convincing proof of homicidal use. Classified as KL Auschwitz-Birkenau “DISINFESTATION gas chamber door,” Oswiecim, 1945, an incorrect designation as it should be DELOUSING. It has not been possible to find where this door was located and we do not know to which delousing installation it belonged. The strips of paper adhering to it are a sure sign that it was a delousing gas chamber door. One of the likely locations would be as an internal door of the Kanada I gas chamber or chambers, if we compare Photos 28 and Photo 14 of the Kanada I gas chamber.
