Inhalation of ample concentrations of hydrogen cyanide gas can fast induce death, which has triggered the use of hydrogen cyanide in gasoline chamber executions (Wexler et al. 1947). A mean lethal concentration for humans was estimated as 546 ppm hydrogen cyanide after a ten-moment exposure (DOA 1976, as cited in Ballantyne 1988). In one scenario, a worker exposed to 200 ppm hydrogen cyanide in the silver plating tank grew to become unconscious and eventually died Although he had received antidotal therapy inside a clinic (Singh et al.
