International Chemical Safety Cards ZINC PHOSPHIDE ICSC: 0602 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: DARK GREY CRYSTALS OR POWDER , WITH CHARACTERISTIC ODOUR. PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on heating and on contact with acids or water producing toxic and flammable fumes of phosphorous and zinc oxides, and phosphine. Reacts violently with strong oxidants causing fire hazard. OCCUPATIONAL EXPOSURE LIMITS (OELs): TLV not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion. INHALATION RISK: Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly specially if powdered. EFFECTS OF SHORT-TERM EXPOSURE: The substance irritates the respiratory tract. Inhalation of phosphine liberated from zinc phosphide may cause lung oedema (see Notes). The substance may cause effects on the liver, kidneys, heart and nervous system. Exposure at high levels may result in death. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Boiling point: 1100°C Melting point: 420°C Relative density (water = 1): 4.6 Solubility in water: none, slowly decomposes

ENVIRONMENTAL DATA	This substance may be hazardous to the environment; special attention should be given to birds, fish and mammals.
NOTES
Reacts violently with fire extinguishing agents such as water and carbon dioxide. Depending on the degree of exposure, periodic medical examination is indicated. The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential. Immediate administration of an appropriate spray, by a doctor or a person authorized by him/her, should be considered. Blue-ox, Kilrat, Mouse-Con, Ratol, Rumetan and Zinc-Tox are trade names. Also consult ICSC # 0694 for Phosphine. Transport Emergency Card: TEC (R)-61G13A NFPA Code: H 3; F 3; R 1;
