  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.        In case of fire in the surroundings, use appropriate extinguishing media.   

 PREVENT DISPERSION OF DUST! AVOID ALL CONTACT!  
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation Cough. Sore throat. Shortness of breath.  Use local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin   Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. Seek medical attention if you feel unwell. 
Eyes Redness. Pain.  Wear safety goggles 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 Nausea. Vomiting. Abdominal pain.  Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Give one or two glasses of water to drink. Refer for medical attention .

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
LAVENDER-TO-DARK-BLUE CRYSTALS. 

Physical dangers
No data. 

Chemical dangers
Decomposes at 735°C. This produces toxic fumes of sulfur oxides. The dust reacts with strong oxidants. This generates fire and explosion hazard. 

Formula: CoSO4
Molecular mass: 155.0
Decomposes at 735°C
Density: 3.71 g/cm³
Solubility in water, g/100ml at 20°C: 36.2 (good) 


EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation and by ingestion. 

Effects of short-term exposure
The is severely irritating to the respiratory tract. The substance is irritating to the eyes. 

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered. 

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation may cause asthma. Ingestion may cause effects on the heart, bone marrow and thyroid. This substance is possibly carcinogenic to humans. Animal tests show that this substance possibly causes toxic effects upon human reproduction. 


Occupational exposure limits
TLV: 0.02 mg/m3, ppm, as TWA; A3 (confirmed animal carcinogen with unknown relevance to humans); BEI issued.
MAK: (as Co, inhalable fraction): skin absorption (H); sensitization of respiratory tract and skin (SAH); carcinogen category: 2; germ cell mutagen group: 3A 

ENVIRONMENT
The substance is toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment. It is strongly advised not to let the chemical enter into the environment. 

NOTES
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.
Depending on the degree of exposure, periodic medical examination is suggested.
Do NOT take working clothes home.
