It uncouples oxidative phosphorylation, so you don’t make ATP. Aren’t you glad you asked? It isn’t suffocation, but apparently that’s what it feels like. Unpleasant, if not painful.

A: Zyklon B [hydrogen cyanide] is much more effective on warm-blooded animals, including humans, than it is on insects. The exposure period (to HCN) is much greater in delousing operations than in homicidal gassings. This means that a much lower concentration is necessary to kill people than to get rid of lice, etc. In delousing, concentrations of up to 16,000 ppm (parts per million) are sometimes used, and exposure time can be up to 72 hours; while 300 ppm will kill people in fifteen minutes or so.Therefore, the HCN in the extermination chambers hardly had time to form compounds on the walls. While some claim that the gas would need a lot of time to kill, because it would have to spread all over the chamber, it simply is not true; the gas chambers were not that large (those in Krematoria II and III were about 210 square meters), and the Zyklon-B was dropped from four openings (still visible in the ruins of the gas chambers). Since the concentration used was higher than the lethal one, death was very swift.During this operation gas-masks must be worn. The ventilation takes place in the reverse direction to the gassing. All windows near the entrance are opened first, then gradually those in the rest of the building. It is advisable to work only for 10 to 15 minutes at a time and then to make interruptions of half an hour, as a precaution against skin poisoning. Depending on concentration, outdoor tempature and weather conditions, ventilation will take at least 10 hours. Clearing of tins and residues may be commenced before the end of airing. Windows and doors must remain open, and gas-masks kept available. ZYKLON tins and absorbent material must always be collected and cleared away before the resumption of work.Zyklon B at Auschwitz-Birkenau was used mainly for two purposes, delousing and murder. The eyewitness testimony to murder by poison is overwhelming. 22 Pressac reconstructs a gassing that took place March 13, 1943: That same night, 1,492 women, children, and old people, selected from a convoy of 2,000 Jews from the Krakow ghetto, were killed in the new crematorium. Six kilos of Zyklon B were poured into the stacks that opened into the four grillework columns implanted between the pillars that supported the ceiling. Within five minutes, all the victims had succumbed. The aeration (8,000 cu m an hour) and deaeration system (same strength) were then started up and, after 15 to 20 minutes, the atmosphere, which had been practically renewed every three to four minutes, was sufficiently pure so that members of the Sonderkommando could enter the stiflingly hot gas chamber. During this first gassing [in the new Krema II gas chamber], the Sonderkommandos wore gas masks as a precaution.

What were the effects of Zyklon B on prisoners in Auschwitz?

Q: Did they suffer ? Or did they have a quick death ? Pain , no pain ?

A: Psychologically, it must have been terrifying, a torturous final few minutes and suffering enough in itself…Johann Kremer, an SS doctor who oversaw the gassings, testified that: “Shouting and screaming of the victims could be heard through the opening and it was clear that they fought for their lives.” Most accounts report that it took between 10 and 20 minutes…depending on dosage used. Some close to the vents died quickly, others were later found to have been foaming at the mouth or bleeding from the ears.
