  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Flammable as dust. Gives off irritating or toxic fumes (or gases) in a fire.  Finely dispersed particles form explosive mixtures in air.    Closed system, dust explosion-proof electrical equipment and lighting. Prevent deposition of dust.  Use dry sand, dry powder. NO carbon dioxide. NO water.   

 PREVENT DISPERSION OF DUST! AVOID ALL CONTACT!  
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation Cough. Shortness of breath.  Use local exhaust or breathing protection.  Fresh air, rest. 
Skin Redness.  Protective gloves. Protective clothing.  Wear protective gloves when administering first aid. Remove contaminated clothes. See Notes. Rinse and then wash skin with water and soap. 
Eyes Redness.  Wear safety spectacles 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. 

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 sealable 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

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
SILVERY METALLIC LUSTROUS SOLID IN VARIOUS FORMS. 

Physical dangers
If dry, it can be charged electrostatically by swirling, pneumatic transport, pouring, etc. Dust explosion possible if in powder or granular form, mixed with air. 

Chemical dangers
Reacts violently with acids. This produces flammable hydrogen. This generates fire and explosion hazard. Reacts violently with strong oxidants. This generates fire and explosion hazard. This produces toxic fumes of nickel monoxide. See ICSC 0926. On combustion, forms toxic gases and vapours including nickel (II) oxide (see ICSC 0926) and nickel carbonyl (see ICSC 0064). 

Formula: Ni
Atomic mass: 58.7
Boiling point: 2730°C
Melting point: 1455°C
Density: 8.9 g/cm³
Solubility in water, mg/l at 37°C: 1.1 (practically insoluble) 


EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation of dust. 

Effects of short-term exposure
May cause mechanical irritation. Inhalation of fume may cause pneumonitis. 

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 respiratory tract. This may result in chronic inflammation of the respiratory tract and fibrosis. This substance is possibly carcinogenic to humans if inhaled. 


Occupational exposure limits
TLV: (inhalable fraction): 1.5 mg/m3, as TWA; A5 (not suspected as a human carcinogen).
MAK: sensitization of respiratory tract and skin (SAH); carcinogen category: 1 

ENVIRONMENT
The substance is harmful to aquatic organisms. The substance may cause long-term effects in the aquatic environment. 

NOTES
At high temperatures, toxic fumes of nickel(II)oxide may be formed (see ICSC 0926).
Depending on the degree of exposure, periodic medical examination is suggested.
The symptoms of asthma often do not become manifest until a few hours have passed and they are aggravated by physical effort.
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.
Isolate contaminated clothing by sealing in a bag or other container.
Do NOT take working clothes home.
