TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible but enhances combustion of other substances. Gives off irritating or toxic fumes (or gases) in a fire.  NO contact with combustible substances or reducing agents.  In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION Risk of fire and explosion on contact with combustible substances.     
 
EXPOSURE   AVOID ALL CONTACT!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation Sore throat. Cough. Shortness of breath.  Use local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin Redness.  Protective gloves. Protective clothing.  First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. 
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. Abdominal pain. Nausea. Vomiting.  Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Rinse mouth. Give one or two glasses of water to drink. Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: P3 filter respirator for toxic particles. 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. Do NOT absorb in saw-dust or other combustible absorbents.

EMERGENCY RESPONSE SAFE STORAGE
  Separated from combustible substances and reducing agents. Well closed. 

IMPORTANT DATA
Physical State; Appearance
RED CRYSTALS. 

Physical dangers
No data. 

Chemical dangers
Decomposes on heating. This produces toxic gases including nitrogen oxides. Reacts with combustible substances. This generates fire hazard. 

Occupational exposure limits
TLV (as Co): 0.02mg/m³ as TWA; A3 (confirmed animal carcinogen with unknown relevance to humans); BEI issued; (ACGIH 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. 

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
Decomposes at 74°C
Melting point: 55°C
Density: 1.88 g/cm³
Solubility in water, g/100ml at 0°C: 133.8  
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 indicated.
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 0783 - Cobalt(II) chloride.
Card has been partially updated in August 2007: see Ingestion First Aid, Occupational Exposure Limits.
