Mildly toxic, carcinogenic. When heated to decomposition it emits highly toxic fumes of metallic nickel, oxides of sulfur, and oxides of nitrogen (Lewis, 3rd ed., 1993, p. 910). The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. It is used for electroplating nickel."}]
