  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 and then wash skin with water and soap. 
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.

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
GREEN-TO-BLACK CRYSTALLINE POWDER. 

Physical dangers
 

Chemical dangers
Reacts violently with halogens and strong oxidants such as hydrogen peroxide. This generates fire and explosion hazard. 

Formula: NiO
Molecular mass: 74.7
Melting point: 1955°C
Density: 6.7 g/cm³
Solubility in water, mg/l at 20°C: 1.1 (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 may be irritating to the eyes, respiratory tract and 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 and nasal mucous membrane. 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 harmful to aquatic organisms. The substance may cause long-term effects in the aquatic environment. 

NOTES
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.
