TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.    In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION      
 
EXPOSURE   PREVENT DISPERSION OF DUST! AVOID ALL CONTACT!   
Inhalation Cough. Sore throat.  Use ventilation (not if powder), local exhaust or breathing protection.  Fresh air, rest. Fresh air, rest. Refer for medical attention. 
Skin Redness.  Protective gloves. Protective clothing.  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
PACKAGING & LABELLING

IMPORTANT DATA
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. The solution in water is a weak acid. 

Occupational exposure limits
TLV (as Ni inhalable fraction): 0.1mg/m³ as TWA; A4 (not classifiable 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, through the skin and by ingestion. 

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
The substance is irritating to the eyes, skin and respiratory tract. 

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 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. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Decomposes at 840°C
See Notes.
Density: 3.7 g/cm³
Solubility in water, g/100ml at 0°C: 29.3  
The substance is toxic to aquatic organisms. 

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 asthma due to this substance should avoid all further contact with this substance.
Do NOT take working clothes home.
The recommendations on this Card also apply to Nickel sulfate hexahydrate (CAS 10101-97-0) and heptahydrate (CAS 10101-98-1).
Card has been partially updated in April 2005: see Occupational Exposure Limits.
