Characteristics of Hydrogen Cyanide
Hydrogen cyanide is a colorless to pale blue liquid or gas. It has a distinct odor resembling bitter almonds. Hydrogen cyanide is particularly dangerous because of its toxic/asphyxiating effects on all life that requires oxygen to survive. HCN combines with the enzymes in tissue associated with cellular oxidation, rendering oxygen unavailable to the tissues and causing death by asphyxia. This suspension only lasts while the cyanide is present. Upon its removal, normal function is restored provided death has not occurred.
