First aid for cyanide poisoning training

Cyanide compounds are very toxic to humans, and inhalation exposure can be rapidly fatal. Cyanide compounds prevent the transfer of oxygen from the blood to body tissues as a result of selective inhibition of respiratory enzymes. The heart and central nervous system are particularly prone to rapid damage. Cyanides can enter the body by inhalation, by contact with the skin or eyes and if swallowed.

Although cyanide poisoning is uncommon, all staff and students working with or studying in areas using or storing cyanide must be familiar with the first aid required for cyanide poisoning. The most likely injury is to the person using the material but production of hydrogen cyanide gas in an open laboratory could have serious consequences for all occupants. The critical factor is the speed with which the first aid can be started after exposure.
