Gives off irritating or toxic fumes (or gases) in a fire. In case of fire in the surroundings: all extinguishing agents allowed. EXPLOSION EXPOSURE AVOID ALL CONTACT!  •INHALATION Cough. Closed system and ventilation. Fresh air, rest. Refer for medical attention.  •SKIN Redness. Pain. Protective gloves. Protective clothing. Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.  •EYES Redness. 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 Do not eat, drink, or smoke during work. Rinse mouth. 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. (Extra personal protection: P3 filter respirator for toxic particles). Do NOT let this chemical enter the environment. Separated from food and feedstuffs . See Chemical Dangers. Do not transport with food and feedstuffs.

International Chemical Safety Cards NICKEL CARBONATE ICSC: 0927 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: LIGHT GREEN CRYSTALS PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on heating and on contact with acids producing carbon dioxide (see ICSC 0021). Reacts violently with aniline, hydrogen sulfide, flammable solvents, hydrazine and metal powders, especially zinc, aluminium and magnesium, causing fire and explosion hazard. OCCUPATIONAL EXPOSURE LIMITS: TLV (as Ni): ppm; 0.2 A1 mg/m3 (ACGIH 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 irritates the skin . 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 lungs. This substance is carcinogenic to humans. PHYSICAL PROPERTIES Decomposes below melting point Density: 2.6g/cm3 Solubility in water: none ENVIRONMENTAL DATA The substance is harmful to aquatic organisms. N O T E S Temperature of decomposition unknown in literature. Do NOT take working clothes home. Anyone who has shown symptoms of asthma due to this substance should avoid all further contact with this substance. The symptoms of asthma 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.
