	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!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Cough. Sore throat.	Use local exhaust or breathing protection.	Fresh air, rest.
Skin	Redness. Pain.	Protective gloves.	Rinse skin with plenty of water or shower. Refer for medical attention if skin irritation occurs.
Eyes	Redness. Pain. Blurred vision.	Wear face shield 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	Abdominal pain. Burning sensation. Nausea. Vomiting. Diarrhoea. Shock or collapse.	Do not eat, drink, or smoke during work. Wash hands before eating.	Do NOT induce vomiting. Give one or two glasses of water to drink. Refer for medical attention .

COPPER SULFATE (anhydrous)

ICSC: 0751

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance WHITE HYGROSCOPIC CRYSTALS. Physical dangers Chemical dangers The solution in water is a weak acid. Decomposes at 650°C. This produces toxic fumes of sulfur oxides (see ICSC 0074). Reacts violently with hydroxylamine. This generates fire hazard. Reacts with magnesium powder. This produces flammable/explosive gas (hydrogen - see ICSC 0001). Reacts with acetylene and potassium chlorate. This generates explosion hazard. Attacks some metals in the presence of water.	Formula: CuSO₄ Molecular mass: 159.6 Decomposes at 650°C Density: 3.6 g/cm³ Solubility in water, g/l at 20°C: 203 (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 substance is irritating to the eyes, skin and respiratory tract. The 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.
