Contact dermatitis from cyanide plating solutions

Two cases of contact dermatitis from electroplating solutions were attributed to irritation from cyanide salts. Both demonstrated similar clinical features. In neither could concomitant contact allergy to other constituents of the plating solutions be demonstrated. In one case, irritation could not be attributed to the alkalinity of the plating solution. Contact dermatitis from cyanide plating solutions may be associated with systemic symptoms, since cyanide is rapidly absorbed through the skin. Poor handling and hygiene techniques in the workplace should be corrected immediately.
