  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Not combustible. Gives off irritating or toxic fumes (or gases) in a fire. Many reactions may cause fire or explosion. See Chemical dangers    NO contact with incompatible substances. See Chemical Dangers.    In case of fire in the surroundings, use appropriate extinguishing media.   

 PREVENT DISPERSION OF DUST! STRICT HYGIENE!  
  SYMPTOMS PREVENTION FIRST AID
Inhalation Cough. Sore throat.  Use local exhaust or breathing protection.  Fresh air, rest. 
Skin   Protective gloves.   
Eyes Redness. Pain. Blurred vision. Burns.  Wear safety goggles in combination with breathing protection.  Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer immediately for medical attention.

COPPER(II) SULFATE, PENTAHYDRATE ICSC: 1416
PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
BLUE SOLID IN VARIOUS FORMS. 

Physical dangers
 

Chemical dangers
The solution in water is a weak acid. Decomposes on heating. This produces toxic fumes of sulfur oxides (see ICSC 0074). Reacts violently with hydroxylamine. This generates fire hazard. Reacts with acetylene and potassium chlorate. This generates explosion hazard. Reacts with magnesium powder. This produces flammable/explosive gas (hydrogen - see ICSC 0001). Attacks some metals in the presence of water. 

Formula: CuSO4.5H2O
Molecular mass: 249.7
Decomposes at 110°C
Density: 2.3 g/cm³
Solubility in water, g/l at 20°C: 317 (freely soluble) 


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 is corrosive to the eyes. The substance is irritating to the respiratory tract. The substance is severely irritating to the gastrointestinal tract. Exposure could cause haemolysis, kidneys and liver impairment. 

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed, especially if powdered. 

Effects of long-term or repeated exposure
Repeated or prolonged inhalation of the aerosol may cause effects on the lungs. The substance may have effects on the liver and kidneys, resulting in impaired functions. 


OCCUPATIONAL EXPOSURE LIMITS
TLV: 0.2 mg/m3, as TWA; (fume): (as Cu):.
TLV: 1 mg/m3, as TWA; (dust and mists): (as Cu):.
MAK: (respirable fraction): 0.01 mg/m3; peak limitation category: II(2); pregnancy risk group: C 

ENVIRONMENT
The substance is very toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment. Bioaccumulation of this chemical may occur along the food chain, for example in fish. It is strongly advised not to let the chemical enter into the environment.
