  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 PREVENTION FIRST AID
Inhalation Cough. Shortness of breath. Sore throat.  Use local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin Redness.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Seek medical attention if you feel unwell. 
Eyes Redness. Pain.  Wear safety goggles 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. Nausea. Vomiting.  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 .

COBALT(II) ACETATE TETRAHYDRATE ICSC: 1128
PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
RED CRYSTALS. 

Physical dangers
 

Chemical dangers
Decomposes on heating. This produces irritating fumes. Reacts with strong oxidants. This generates fire and explosion hazard. 

Formula: C4H6CoO4.4H2O
Molecular mass: 249.1
Melting point: 140°C
Density: 1.7 g/cm³
Solubility in water, g/100ml at 25°C: (very 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 substance is irritating to the eyes, skin and respiratory tract. 

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. Repeated or prolonged inhalation may cause effects on the lungs. Ingestion may cause effects on the heart, thyroid and bone marrow. This substance is possibly carcinogenic to humans. Animal tests show that this substance possibly causes toxicity to human reproduction or development. 


OCCUPATIONAL EXPOSURE LIMITS
 

ENVIRONMENT
Bioaccumulation of this chemical may occur in seafood. 

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.
The apparent melting point caused by loss of crystal water is given.
The recommendations on this Card also apply to Cobalt (II) acetate anhydrous (CAS 71-48-7).
