International Chemical Safety Cards COBALT(II) NITRATE HEXAHYDRATE ICSC: 0784 Cobaltous nitrate hexahydrate Co(NO3)2 • 6H2O Molecular mass: 291.03 ICSC #    0784 CAS #     10026-22-9 RTECS # QU7355500 March 14, 2001 Peer reviewed TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Not combustible but enhances combustion of other substances. Gives off irritating or toxic fumes (or gases) in a fire. NO contact with combustibles andreducing agents. In case of fire in the surroundings: all extinguishing agents allowed. EXPLOSION Risk of fire and explosion on contact with combustible substances. EXPOSURE AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR!  •INHALATION Sore throat. Cough. Shortness of breath. Local exhaust or breathing protection. Fresh air, rest. Refer for medical attention.  •SKIN Redness. Protective gloves. Protective clothing. First rinse with plenty of water, then remove contaminated clothes and rinse again.  •EYES Redness. Pain. Safety goggles, or eye protection in combination with breathing protection if powder. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Abdominal pain. Nausea. Vomiting. Do not eat, drink, or smoke during work. Wash hands before eating. Rinse mouth. Give plenty of water to drink. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Do NOT absorb in saw-dust or other combustible absorbents. Do NOT let this chemical enter the environment. (Extra personal protection: P3 filter respirator for toxic particles.) Separated from combustible and reducing substances. Well closed. R: S: SEE IMPORTANT INFORMATION ON BACK ICSC: 0784 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities (C) IPCS CEC 1994.

International Chemical Safety Cards COBALT(II) NITRATE HEXAHYDRATE ICSC: 0784 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: RED CRYSTALS . PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on heating producing toxic gases , including nitrogen oxides . Reacts with combustible substances causing fire hazard. OCCUPATIONAL EXPOSURE LIMITS: TLV (as Co): 0.02 mg/m3 (as TWA) A3 (ACGIH 2000). MAK: class 2 (2000) ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its aerosol and by ingestion. INHALATION RISK: Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed . EFFECTS OF SHORT-TERM EXPOSURE: The substance is irritating to the eyes , the skin and the respiratory tract. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation exposure may cause asthma. The substance may have effects on the heart, thyroid and bone marrow , resulting in cardiomyopathy, goiter and polycythemia. This substance is possibly carcinogenic to humans. Animal tests show that this substance possibly causes toxic effects upon human reproduction. Animal tests show that this substance possibly causes malformations in human babies. PHYSICAL PROPERTIES Decomposes below boiling point at 74°C Melting point: 55°C Density: 1.88 g/cm3 Solubility in water, g/100 ml at 0°C: 133.8 ENVIRONMENTAL DATA See Notes. N O T E S Anyone who has shown symptoms of asthma due to this substance should avoid all further contact with this substance. Depending on the degree of exposure, periodic medical examination is indicated. Environmental effects from the substance have not been investigated but data on cobalt ion suggest that it may be hazardous to aquatic organisms. Also consult ICSC on cobalt salts such as 0783 - Cobalt(II) chloride. ADDITIONAL INFORMATION ICSC: 0784 COBALT(II) NITRATE HEXAHYDRATE (C) IPCS, CEC, 1994
