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	Pain. Redness. 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. Diarrhoea. Nausea. Vomiting. 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.

PHYSICAL STATE; APPEARANCE:
BLUE SOLID IN VARIOUS FORMS

PHYSICAL DANGERS:

CHEMICAL DANGERS:
The substance decomposes on heating producing toxic and corrosive fumes including sulfur oxides . The solution in water is a weak acid. Attacks many metals in the presence of water.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: (as copper) 1 mg/m³ as TWA; (ACGIH 2004).
MAK: (as copper) (Inhalable fraction) 0.1 mg/m³;
Peak limitation category: II(2); Pregnancy risk group: D;
(DFG 2004).

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.
