  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.        In case of fire in the surroundings, use appropriate extinguishing media.   

 AVOID ALL CONTACT!  
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation Cough.  Use closed system or ventilation (not if powder).  Fresh air, rest. Refer for medical attention. 
Skin Redness. Pain.  Protective gloves. Protective clothing.  Wear protective gloves when administering first aid. Remove contaminated clothes. See Notes. Rinse skin with plenty of water or shower. Refer for medical attention . 
Eyes Redness.  Wear 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 refer for medical attention. 
Ingestion   Do not eat, drink, or smoke during work.  Rinse mouth. Refer for medical attention . 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations. 

According to UN GHS Criteria

May cause cancer if inhaled
Causes damage to the lungs through prolonged or repeated exposure if inhaled
Very toxic to aquatic life with long lasting effects 

Transportation
UN Classification
UN Hazard Class: 6.1; UN Pack Group: III

NICKEL CARBONATE ICSC: 0927
PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
LIGHT GREEN CRYSTALS. 

Physical dangers
 

Chemical dangers
Decomposes on heating and on contact with acids. This produces carbon dioxide (see ICSC 0021). This produces toxic fumes of nickel monoxide. See ICSC 0926. 

Formula: NiCO3
Molecular mass: 118.7
Melting point: No melting point; decomposes on heating
Density: 2.6 g/cm³
Solubility in water, mg/l at 25°C: 93 (practically insoluble) 


EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion. 

Effects of short-term exposure
The substance is irritating to the skin. 

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed. 

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation may cause asthma. The substance may have effects on the lungs. This substance is carcinogenic to humans if inhaled. 


Occupational exposure limits
TLV: (inhalable fraction): 0.1 mg/m3, as TWA; A4 (not classifiable as a human carcinogen).
MAK: sensitization of respiratory tract and skin (SAH); carcinogen category: 1 

ENVIRONMENT
The substance is very toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment. It is strongly advised not to let the chemical enter into the environment. 

NOTES
Temperature of decomposition unknown in literature.
Anyone who has shown symptoms of sensitization due to this substance should avoid all further contact with nickel, nickel compounds and other metal compounds of e.g. copper, chromium and cobalt.
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.
Isolate contaminated clothing by sealing in a bag or other container.
Do NOT take working clothes home.
