Safety Profile
Poison by inhalation and ingestion. Human pulmonary system effects by inhalation. See also PLATINUM COMPOUNDS. An explosively unstable compound. Incompatible with KOH (boiling with alkali yields a product which, after drying, will explode @ 205' or if mixed with combustibles). When heated to decomposition it emits very toxic fumes of Cl-, NOx, and NH3.
