TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Flammable as dust. Gives off irritating or toxic fumes (or gases) in a fire.    Use dry sand. NO carbon dioxide. NO water. 
EXPLOSION Finely dispersed particles form explosive mixtures in air.  Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent deposition of dust.   
 
EXPOSURE   PREVENT DISPERSION OF DUST! AVOID ALL CONTACT!   
Inhalation Cough. Shortness of breath.  Use local exhaust or breathing protection.  Fresh air, rest. 
Skin   Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes   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
PACKAGING & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Vacuum spilled material with specialist equipment. Carefully collect remainder. Then store and dispose of according to local regulations.   
EC Classification

EMERGENCY RESPONSE SAFE STORAGE
  Separated from strong acids. 

IMPORTANT DATA
Physical State; Appearance
SILVERY METALLIC SOLID IN VARIOUS FORMS. 

Physical dangers
Dust explosion possible if in powder or granular form, mixed with air. 

Chemical dangers
Reacts with titanium powder, potassium perchlorate and oxidants such as ammonium nitrate. This generates fire and explosion hazard. Reacts slowly with non-oxidizing acids more rapidly with oxidizing acids. Toxic gases and vapours (such as nickel carbonyl) may be released in a fire involving nickel. 

Occupational exposure limits
TLV (inhalable fraction): 1.5mg/m³ as TWA; A5 (not suspected as a human carcinogen); (ACGIH 2004).
MAK (inhalable fraction): Carcinogen category: 1; Sensitization of respiratory tract and skin (SAH); (DFG 2004). 

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

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
May cause mechanical irritation. Inhalation of fume may cause pneumonitis. 

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


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Boiling point: 2730°C
Melting point: 1455°C
Density: 8.9 g/cm³
Solubility in water: none 
 

NOTES
At high temperatures, nickel oxide fumes will be formed.
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.
Rest and medical observation are therefore essential.
Anyone who has shown symptoms of asthma due to this substance should avoid all further contact with this substance.
