Hydrogen cyanide is a colorless to a 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 requiring oxygen to survive. HCN combines with the enzymes in tissue associated with cellular oxidation. What this means is they render oxygen unavailable to the tissues 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.

Effects of Various HCN Levels

10-50                                            Headache, dizziness, unsteadiness

0-100                                            Feeling of suffocation, nausea

100-200                                       Death from exposure in 30 to 60 minutes
