Description

White, granular or crystalline solid with a faint, almond-like odor; [NIOSH] Deliquescent; [CHEMINFO]

Sources/Uses

Used to clean metals, chelate compounds, and extract gold and silver; Used to manufacture dyes, agricultural chemicals, and pharmaceuticals; Also used in electroplating, heat treating, and metal stripping; Used as a rodenticide (killing coyote, fox, and wild dogs) and insecticide (fumigating trucks and post-harvest application to fruit trees); [HSDB]

Comments

There are two common scenarios for cyanide poisoning in the industrial setting: 1) mixing acid and cyanide solutions, and 2) pouring cyanide wastes into non-alkaline solutions. Mixing cyanide salts with water, e.g., showering in clothes contaminated with cyanides, will generate hydrogen cyanide gas. Dermal absorption of cyanide salts deposited on large areas of skin can result in fatal poisoning.
