THE RUDOLF REPORT

GERMAR RUDOLF · THE RUDOLF REPORTlaborious and expensive task, leading to massive, irreparable damageto the roofs’ layer of tar and upper cement layer; add (2×4=)eight brick or concrete chimneys of at least 1 m height to lead theholes through the layer of soil on top of the roofs, and attemptingto repair the damage done to the roof by the violent hole piercingprocess – another laborious, material consuming, and expensivetask; design and construct (2×4) eight wire mash columns 3 mhigh, consisting of three parts: a panic-proof, outer column madeof massive steel, a middle wire mesh column (with no purpose atall but to hinder the HCN from spreading out), and a removableinner wire mesh column, another laborious, material as well astime consuming, and expensive task; finding a way to anchorthese eight devices panic-proof in the concrete floor, ceiling andpillars, another laborious and expensive task; all these works hadto be planned, approved, tested, and material had to be allotted,leaving a thick and long ‘paper trail’ of documents (which, by theway, doesn’t exist); but finally, all one would possess at the endwould be a primitive device allowing for the simple introductionof Zyklon B by pouring it into the inner column; one had to sit andwait for a long time until a lethal amount of HCN had evaporatedfrom the Zyklon B carrier and had spread into the morgue, or alternatively,one had to apply an excessive amount of Zyklon B toensure high evaporation rates for quick execution success, and removeand destroy the Zyklon B after the gassing, though only afraction of the HCN had been released by then. 273But there was a second, much simpler option:b) Installing a simple basket – to hold Zyklon B – in the air intakeshaft of morgue 1 right after the easily accessible intake ventilator,which then would blow the HCN vapors right into the ‘gas chamber’,similar to the DEGESCH circulation procedure; thus reducingthe gassing time and the amount of Zyklon B required to afraction compared to any scenario where Zyklon B is simply keptclosely together on heaps without any moving air. 274273 For evaporation rates of Zyklon B, see chapter 7.2. and 7.3.1.3.274 The brick-built air intake duct was easily accessible from the attic, where the fans were installed,and the ground floor; see J.-C. Pressac, op. cit. (note 67), pp. 276, 291, 329, 369. Theuse of the air intake fan to introduce HCN would have lead to some HCN losses through theair exhaust chimney already during the gassing, thus endangering anybody close to those crematoria,but certainly not more than would have been the case when all the HCN had to beremoved after the end of a hypothetical gassing, so this would not be an argument against this132
