Some question Dussander's description of carbon monoxide gas being introduced to gas chambers through pipes, pointing out that Nazi extermination camps used Zyklon B pellets dropped through openings in the roofs of the chambers, which then released prussic acid (hydrogen cyanide) gas. While the extermination camps, Auschwitz I, Auschwitz II-Birkenau, Majdanek and KZ camp Sachsenhausen and Dacau did use the Zyklon B method, most of the other major extermination camps (Belzec, Sobibor, and Treblinka II) and KZ camps used large gas or diesel engines to produce carbon monoxide exhaust, which was then routed to the gas chambers through pipes. This was learned from the experiences of the T-4 project. (The Chelmno camp had no gas chambers, it instead used gas vans, in which the vans' own carbon monoxide exhaust was routed to the rebuild and airtight cargo bay of the vans, which held the victims.)
