COBALT (II) CHLORIDE ICSC: 0783
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
PALE-BLUE, HYGROSCOPIC POWDER, TURNS PINK ON EXPOSURE TO MOIST AIR.

CHEMICAL DANGERS:
Reacts violently with alkali metals such as potassium or sodium causing fire and explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV (as Co): 0.02 mg/m^3 (as TWA) A3 (ACGIH 1997).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion.

INHALATION RISK:
Evaporation at 20C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes, the skin and the respiratory tract. Inhalation of aerosol may cause asthmatic reactions (see Notes).

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 , resulting in cardiomyopathy. This substance is possibly carcinogenic to humans.
PHYSICAL PROPERTIES
Boiling point: 1049C
Melting point: 735C
Relative density (water = 1): 3.3
Solubility in water, g/100 ml at 7C: 450
ENVIRONMENTAL DATA
The substance is toxic to aquatic organisms.
NOTES
Depending on the degree of exposure, periodic medical examination is indicated. 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 hydrate.
