7. ZYKLON B FOR THE KILLING OF HUMAN BEINGSme whether I would rely upon these values and enter such a ‘gaschamber’ without a gas mask, I would reply that I preferred to insistupon the performance of a traditional chemical test beforehand. Thesimple reason for this is that all reliable calculation would be renderedimpossible by the Zyklon B trapped beneath the bodies, as well as bythe wet bodies moistened with hydrogen cyanide.The rooms in crematoria IV and V which purportedly served as‘gas chambers,’ like farmhouses I and II, allegedly had no ventilationinstallation and only slight ventilation possibilities by means of a fewdoors. The use of a room without efficient ventilation installations formass murder at a time and in a place, where even dissecting rooms,wash rooms, and laying-out rooms could be and were equipped withventilation installations, and where many ventilation fans were supplyinglots of fresh air in disinfestation rooms right next door, is so absurdthat any rational human being ought to refuse to take such stories seriously.7.3.2.3. Simulation CalculationsThe following are the results a series of simulation calculations forthe determination of the relative saturation of the masonry with hydrogencyanide based on the assumption that similar concentrations ofhydrogen cyanide are used in all cases. In so doing, a distinction ismade between two sets of circumstances:1. Disinfestation chamber. The constant concentration assumed forthe calculation amounts to 10 g/m³. A constant concentration cannot,however, be assumed, particularly for the existing epidemic disinfestationinstallations BW 5a und 5b existing in Birkenau, since great quantitiesof hydrogen cyanide would escape through the non-airtight roofon the one hand, and since both the masonry and the clothing wouldhave absorbed considerable quantities of hydrogen cyanide over time(see chapter 7.3.1.3.3.). We therefore assume two models, as follows:a) one gassing daily with a constant concentration over 6 hours, and b)one gassing daily with 12 hours of constant concentration. 481 This481 In order to keep the HCN concentration in those make-shift delousing chambers of BW 5a andBW 5b constant over 12 hours, this would have required the application of an initial concentrationat least twice or thrice as high as 10 g/m², but this would have been impossible due tolack of sufficient Zyklon B. The quantities of Zyklon B necessary for such use would havecorresponded to 24 to 30 kg per day, or approximately 9 to 11 tons per year, which is roughlythe total quantity delivered to the camp, leaving no HCN for homicidal gassings. Hence, this227
