International Chemical Safety Cards ZINC NITRATE ICSC: 1206 Zinc dinitrate Nitric acid, zinc salt N2O6Zn / Zn(NO3)2 Molecular mass: 189.4 ICSC #    1206 CAS #     7779-88-6 RTECS # ZH4772000 UN #        1514 October 25, 1994 Peer reviewed TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Not combustible but enhances combustion of other substances. Many reactions may cause fire or explosion. Gives off irritating or toxic fumes (or gases) in a fire. NO contact with combustible and incompatible substances. Water in large amounts. EXPLOSION In case of fire: keep drums, etc., cool by spraying with water. EXPOSURE PREVENT DISPERSION OF DUST!  •INHALATION Cough. Sore throat. Local exhaust or breathing protection. Fresh air, rest. Refer for medical attention.  •SKIN Redness. Pain. Protective gloves. Rinse and then wash skin with water and soap.  •EYES Redness. Pain. Blurred vision. Safety goggles, or eye protection in combination with breathing protection. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Abdominal cramps. Abdominal pain. Blue lips or fingernails. Nausea. Do not eat, drink, or smoke during work. Wash hands before eating. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Wash away remainder with plenty of water. Do NOT absorb in saw-dust or other combustible absorbents. (extra personal protection: P2 filter respirator for harmful particles). Separated from combustible and reducing substances. Cool. Dry. R: S: UN Hazard Class: 5.1 UN Packing Group: II SEE IMPORTANT INFORMATION ON BACK ICSC: 1206 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities (C) IPCS CEC 1994. No modifications to the International version have been made except to add the OSHA PELs, NIOSH RELs and NIOSH IDLH values.

International Chemical Safety Cards ZINC NITRATE ICSC: 1206 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS CRYSTALS. PHYSICAL DANGERS: CHEMICAL DANGERS: May explode on heating. The substance decomposes on heating or on burning producing toxic fumes including nitrogen oxides and zinc oxides. The substance is a strong oxidant and reacts violently with combustible and reducing materials. Reacts violently with carbon, copper, metal sulfides, phosphorus and sulfur. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation and by ingestion. INHALATION RISK: No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20°C. EFFECTS OF SHORT-TERM EXPOSURE: The substance irritates the eyes, the skin and the respiratory tract. See Notes. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Melting point: ca. 110°C Relative density (water = 1): 2.07 (hexahydrate) Solubility in water: good ENVIRONMENTAL DATA This substance may be hazardous to the environment; special attention should be given to crustacea. N O T E S Hydration may increase the degree of hazard. Other melting points: 45.5°C (trihydrate); 36.4°C (hexahydrate). Rinse contaminated clothes (fire hazard) with plenty of water.
