  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.    See Chemical Dangers.  See Chemical Dangers  In case of fire in the surroundings, use appropriate extinguishing media.  In case of fire: keep drums, etc., cool by spraying with water. 

 PREVENT DISPERSION OF DUST! AVOID ALL CONTACT!  
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation Cough. Sore throat.  Use closed system or ventilation (not if powder).  Fresh air, rest. Refer for medical attention. 
Skin Redness.  Protective gloves. Protective clothing.  Wear protective gloves when administering first aid. Remove contaminated clothes. Rinse skin with plenty of water or shower. 
Eyes Redness.  Wear safety spectacles, face shield or eye protection in combination with breathing protection if powder.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Abdominal pain. Dizziness. Headache. Nausea. Vomiting.  Do not eat, drink, or smoke during work.  Rinse mouth. Give one or two glasses of water to drink. 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 sealable containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.

NICKEL(II)SULPHATE ICSC: 0063
PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
YELLOW-TO-GREEN CRYSTALS. 

Physical dangers
 

Chemical dangers
Decomposes at 848°C. This produces toxic fumes of sulfur trioxide and nickel monoxide. See ICSC 0926 and 1202. Reacts with oxidants. This generates fire and explosion hazard. The solution in water is a weak acid. 

Formula: NiSO4
Molecular mass: 154.8
Melting point: No melting point; decomposes at 848°C
See Notes.
Density: 3.7 g/cm³
Solubility in water, g/100ml at 20°C: 29.3 (freely soluble) 


EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation, by ingestion and through the skin. 

Effects of short-term exposure
The substance is irritating to the skin, eyes and respiratory tract. 

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. Repeated or prolonged inhalation of the aerosol may cause effects on the lungs. The substance may have effects on the nasal sinuses. This may result in inflammation and ulceration. This substance is carcinogenic to humans if inhaled. May cause toxicity to human reproduction or development. 


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
At temperatures up to 330 °C nickel (II) sulphate containing water of crystallization will gradually release its total water content.
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 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.
Do NOT take working clothes home.
Isolate contaminated clothing by sealing in a bag or other container.
The recommendations on this Card also apply to Nickel sulfate hexahydrate (CAS 10101-97-0) and heptahydrate (CAS 10101-98-1).
