TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION         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! STRICT HYGIENE!  
Inhalation Cough. Shortness of breath. Wheezing. Local exhaust or breathing protection. Fresh air, rest. Refer for medical attention.
Skin   Protective gloves. Protective clothing. Remove contaminated clothes. Rinse skin with plenty of water or shower.
Eyes Redness. Pain. 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 take to a doctor.
Ingestion Abdominal pain. Diarrhoea. Nausea. Vomiting. Do not eat, drink, or smoke during work. Rinse mouth. Give plenty of water to drink. Refer for medical attention.

PALE- BLUE, HYGROSCOPIC POWDER. TURNS PINK ON EXPOSURE TO AIR AND MOISTURE.

Chemical dangers
Reacts with oxidants causing fire and explosion hazard.

Occupational exposure limits
TLV: (as Co) 0.02 mg/m³ as TWA; A3; BEI issued; (ACGIH 2004).
MAK not established.

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

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed.

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

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

Boiling point: 1049°C
Melting point: 735°C
Density: 3.4 g/cm³
Solubility in water, g/100 ml at 20°C: 53
Octanol/water partition coefficient as log Pow: 0.85
The substance is toxic to aquatic organisms.

NOTES
Depending on the degree of exposure, periodic medical examination is suggested.
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 with this substance.
Do NOT take working clothes home.
The recommendations on this Card also apply to Cobalt (II) chloride hydrates: Cobalt (II) chloride hexahydrate (CAS 7791-13-1), Cobalt (II) chloride dihydrate (CAS 14216-74-1).
