RIDADR: 1714
RTECS: ZH4900000
HazardClass: 4.3
PackingGroup: I
Human poison by ingestion causing nausea, vomiting, death. Flammable when exposed to heat or flame. This material is stable while kept dry. In moist air, it decomposes slowly. Reacts violently with acids or acid fumes to emit the highly toxic and flammable phosphine. Violent reaction with concentrated sulfuric acid, nitric acid, and oxidizing materials. Incompatible with HCl, H₂SO₄. When heated to decomposition it emits toxic fumes of PO_x and ZnO. Used as an acute rodenticide. See also PHOSPHIDES and ZINC COMPOUNDS.
