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.
