Tounderstand how this would effect the ventilation, we have carried out asimulation calculation based on the following assumption:1. At 15°C, the moist Zyklon B releases hydrogen cyanide in the dryenvironment in the manner described by R. Irmscher (see chapter7.2.).2. Reaching an average concentration of hydrogen cyanide throughoutthe entire chamber of approximately 5-6 g/m³ after 5 minutesand/or approximately 10-12 g/m³ after 10 minutes (0.5 or 1 Vol.-%)—necessary for the rapid killing of all victims according to theeyewitnesses—requires the use of approximately 20 kg of ZyklonB (see chapter 7.3.1.3.).3. The ventilation is turned on after 10 minutes, reducing the concentrationof hydrogen cyanide according to the well-known formula(see chapter 7.3.2.2.2.)The results may be taken from the Graph 15 for four air exchanges224
