Please show evidence that Hydrogen Cyanide molecules have the intelligence required to recognize that humans have a large proportion of water in their bodies, and therefore will travel through the skin to reach that water.
Utter nonsense, Kiwichap.
And Hydrogen Cyanide is easily vaporized, as can be seen by Irmscher's study on Zyklon-B, clinging to items, but not necessary humans unless they are covered in sweat. This is why it is highly discouraged from producing sweat when dealing with the poison.http://www.holocaust-history.org/works/irmscher-1942/htm/p037.htm
So no amount of ventilation will remove cyanide once it has been absorbed in a human body.
Right, but by far the majority of the cyanide concentration will be absorbed through the lungs, NOT the skin.
And it takes time for cyanide concentrations to be absorbed through the skin. From the "Chemistry of Toxicology" by Harvey Elkins:
In high concentrations, hydrogen cyanide is absorbed through the skin; therefore complete reliance cannot be placed on a gas mask. After 1 hour exposure, 100 to 250 ppm of HCN are dangerous.
So over one hour to a direct exposure of 100-250 ppm is dangerous through skin absorbtion. By this time, unless heavy-duty gas masks are involved, the worker would be dead anyway, through entering the workers' lung cavity. You cited OSHA yourself, which states:
U.S Department of Labor
Occupational Safety and Health Administration
2. Effects on Humans: Hydrogen cyanide can cause rapid death due to metabolic asphyxiation. Death can occur within seconds or minutes of the inhalation of high concentrations of hydrogen cyanide gas. A recent study reports an estimated LC(50) in humans of 3,404 ppm for a 1-minute exposure; other sources report that 270 ppm is fatal after 6 to 8 minutes, 181 ppm after 10 minutes and 135 ppm after 30 minutes [Hathaway et al. 1991]. http://www.osha.gov/SLTC/healthguidelin ... uresources
A 100-250 ppm exposure to HCN would kill through the lungs say in 10-35 minutes, not enough time to be saturating the corpses.
Yet this is all pie-in-the-sky, for any type of ventilation would not let such a concentration be maintained in the delousing chambers for such poisoning to take place.
Can you imagine a pile of 2,000 dead cyanided Jews, fresh out of Auschwitz 1, stacked up waiting to be cremated? Nobody would go near them.
I cannot imagine it for other reasons than the Jews bodies' being cyanide laden. A 1993 American Family Physician article, quoting a US Dept. of Health and Human services on "Cyanide Toxicity" states:
Cyanide is absorbed through the lungs, gastrointestinal tract, and skin. Symptoms can occur within seconds of HCN [cyanide gas] inhalation; ....Cyanide is readily absorbed through the mucous membranes and the eyes. Clinical cases of cyanide poisoning after dermal exposure are rare and most often have involved burns with molten cyanide salts or immersion in cyanide solutions. http://www.nizkor.org/ftp.cgi/camps/aus ... ous-claims
Your cyanide-saturated bodies simply would not pose a threat to any workers' lives, Kiwichap.
Anyway, the trappers must have had a miniscule amount of cyanide on ther fingers. When rolling a cigarette, and licking the paper, they got enough cyanide on their tongues to kill them.
Ingested and breathed is completely different from entering through the skin, and are considerably more deadly via cyanide.
