Important Data
|
Physical State; Appearance:
LAVENDER TO DARK BLUE CRYSTALS.
Physical Dangers:
Chemical Dangers:
The substance decomposes
on heating to 735°C,
producing
toxic fumes
of
sulfur oxides
.
Reacts as a dust with strong oxidants
causing fire and explosion hazard.
Occupational Exposure Limits:
TLV: (as Co) 0.02 mg/m3 as TWA; A3 (confirmed animal carcinogen with unknown relevance to humans); BEI issued; (ACGIH 2004).
MAK: sensitization of respiratory tract and skin (Sah);
Carcinogen category: 2; Germ cell mutagen group: 3A;
(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,
the skin
and
the respiratory tract.
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
, resulting 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.

N O T E S
|
|
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 0783 - Cobalt(II) chloride.
