Below is taken from his report.
Construction of these facilities further shows that they were never used as gas chambers. None of these facilities were sealed or gasketed. No provision was ever made to prevent condensation of gas on the walls, floor or ceiling. No provision ever existed to exhaust the air-gas mixture from these buildings. No provision ever existed to introduce or distribute the gas throughout the chamber. No explosion-proof lighting existed and no attempt was ever made to prevent gas from entering the crematories, even though the gas is highly explosive. No attempt was made to protect operating personnel from exposure to the gas or to protect other nonparticipating persons from exposure. Specifically, at Auschwitz, a floor drain in the alleged gas chamber was connected directly to the camp's storm drain system. At Majdanek a depressed walkway around the alleged gas chambers would have collected gas seepage and resulted in a death trap for camp personnel. No exhaust stacks ever existed. Hydrogen cyanide gas is an extremely dangerous and lethal gas, and nowhere were there any provisions to effect any amount of safe handling. The chambers were too small to accommodate more than a simple fraction of the alleged numbers. Plain and simple, these facilities could not have operated as execution gas chambers Leuchter, Fred A., "The Leuchter Report: The How and the Why," The Journal of Historical Review, Vol. 9, No. 2, Summer 1989, p.139
