International Chemical Safety Cards COPPER SULFATE (anhydrous) ICSC: 0751 Cupric sulphate Sulfuric acid, copper(2+) salt(11) CuSO4 Molecular mass: 159.6 ICSC #    0751 CAS #     7758-98-7 RTECS # GL8800000 EC #         029-004-00-0 October 18, 2001 Peer reviewed 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!  •INHALATION Cough. Sore throat. Local exhaust or breathing protection. Fresh air, rest.  •SKIN Redness. Pain. Protective gloves. Rinse skin with plenty of water or shower.  •EYES Redness. Pain. Blurred vision. 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 take to a doctor.  •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 plenty of water to drink. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting then remove to safe place. (Extra personal protection: P2 filter respirator for harmful particles.) Do NOT let this chemical enter the environment. Well closed. Dry.

International Chemical Safety Cards COPPER SULFATE (anhydrous) ICSC: 0751 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: WHITE HYGROSCOPIC CRYSTALS PHYSICAL DANGERS: CHEMICAL DANGERS: Reacts violently with hydroxylamine causing fire hazard. Reacts with magnesium forming flammable/explosive gas (hydrogen - see ICSC0001) . Attacks iron and zinc in the presence of water. OCCUPATIONAL EXPOSURE LIMITS: TLV (as copper): 1 mg/m3 (as TWA) (ACGIH 2001). MAK: (as copper) 1 mg/m³; Peak limitation category: II, 1 (DFG 2000). ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its aerosol and by ingestion. 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 SHORT-TERM EXPOSURE: The substance is severely irritating to the eyes and the skin . The aerosol is irritating to the respiratory tract . Corrosive on ingestion. If ingested, the substance may cause effects on the blood , kidneys and liver , resulting in hemolytic anemia, kidney impairment and liver impairment . EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Lungs may be affected by repeated or prolonged exposure to the aerosol. The substance may have effects on the liver when ingested . PHYSICAL PROPERTIES Decomposes below boiling point at 650°C Density: 3.6 g/cm3 Solubility in water, g/100 ml at 20°C: 20.3 ENVIRONMENTAL DATA The substance is very toxic to aquatic organisms. Bioaccumulation of this chemical may occur along the food chain, for examplein fish. It is strongly advised that this substance does not enter the environment.
