storage facilities for plundered goods; it derived its name from the inmates' view of Canada as a land of plenty. Inside the crematoria The crematoria consisted of a dressing room, gas chamber, and furnace room. In crematoria II and III, the dressing room and gas chamber were underground; in IV and V, they were on the ground floor. The dressing room had numbered hooks on the wall to hang clothes. In crematorium II, there was also a dissection room (Sezierraum). SS officers told the victims they had to take a shower and undergo delousing. The victims undressed in the dressing room and walked into the gas chamber; signs said "Bade" (bath) or "Desinfektionsraum" (disinfection room). A former prisoner testified that the language of the signs changed depending on who was being killed. Some inmates were given soap and a towel. A gas chamber could hold up to 2,000; one former prisoner said it was around 3,000. The Zyklon B was delivered to the crematoria by a special SS bureau known as the Hygiene Institute. After the doors were shut, SS men dumped in the Zyklon B pellets through vents in the roof or holes in the side of the chamber. The victims were usually dead within 10 minutes; Rudolf Höss testified that it took up to 20 minutes.

It was found in 1952, signed "A.Y.R.A": Use of corpses Sonderkommando wearing gas masks dragged the bodies from the chamber. They removed glasses and artificial limbs and shaved off the women's hair; women's hair was removed before they entered the gas chamber at Bełżec, Sobibór, and Treblinka, but at Auschwitz it was done after death. By 6 February 1943, the Reich Economic Ministry had received 3,000 kg of women's hair from Auschwitz and Majdanek. The hair was first cleaned in a solution of sal ammoniac, dried on the brick floor of the crematoria, combed, and placed in paper bags. The hair was shipped to various companies, including one manufacturing plant in Bremen-Bluementhal, where workers found tiny coins with Greek letters on some of the braids, possibly from some of the 50,000 Greek Jews deported to Auschwitz in 1943. When they liberated the camp in January 1945, the Red Army found 7,000 kg of human hair in bags ready to ship. Just before cremation,
