CDC Facts About Cyanide

CDC Facts About Cyanide

Cyanide gas is most dangerous in enclosed places where the gas will be trapped. Cyanide gas evaporates and disperses quickly in open spaces making it less harmful outdoors. Cyanide gas is less dense than air so it will rise. Cyanide prevents the cells of the body from using oxygen. When this happens the cells die.
