Acrolein is a severe pulmonary irritant and lacrimating agent, historically
it has been used as a chemical weapon during World War I. Acrolein is
described as having a piercing, disagreeable, acrid odor. Skin exposure
causes serious damage. Acrolein concentrations of 2 PPM are immediately
dangerous to life. Acrolein may be easily produced by the action of
approximately 1 part sodium bisulfate on 3 parts glycerine by weight.
