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   AVOID ALL CONTACT!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation Cough. Laboured breathing. Shortness of breath. Sore throat.  Use local exhaust or breathing protection.  Fresh air, rest. Artificial respiration may be needed. Refer for medical attention. 
Skin Redness. Pain.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
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 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 . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.

EMERGENCY RESPONSE SAFE STORAGE
  Separated from strong oxidants. 

IMPORTANT DATA
Physical State; Appearance
PINK-TO-RED CRYSTALS. 

Physical dangers
 

Chemical dangers
Decomposes above 100°C . This produces toxic fumes of of sulfur oxides. The dust reacts with strong oxidants. This generates fire and explosion hazard. 

Occupational exposure limits
TLV (as Co): 0.02mg/m³ as TWA; A3 (confirmed animal carcinogen with unknown relevance to humans); BEI issued; (ACGIH 2004).
MAK: Carcinogen category: 2; Germ cell mutagen group: 3A; Sensitization of respiratory tract and skin (SAH); (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. 

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

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


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Boiling point: 420°C
Melting point: 96.8°C
Density: 1.95 g/cm³
Solubility in water, g/100ml at 3°C: 60.4  
See Notes. 

NOTES
Anyone who has shown symptoms of asthma due to this substance should avoid all further contact with this substance.
Depending on the degree of exposure, periodic medical examination is suggested.
Environmental effects from the substance have not been investigated but data on cobalt ion suggest that it may be hazardous to aquatic organisms.
Also consult ICSC on cobalt salts such as ICSC 0783 - Cobalt(II) chloride.
Card has been partly updated in April 2005.
