COBALT SULFIDE ICSC: 1529
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
GREY POWDER OR REDDISH-SILVERY CRYSTALS.

CHEMICAL DANGERS:
The substance decomposes on heating producing toxic gases and irritating fumes including hydrogen sulfide and sulfur oxides. Reacts with strong oxidants.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: (as cobalt) 0.02 mg/m as TWA; A3; BEI issued; (ACGIH 2004).
MAK: (inhalable fraction) Sah; Carcinogen category: 2; Germ cell mutagen group: 3A; (DFG 2003).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation.

INHALATION RISK:
A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered.

EFFECTS OF SHORT-TERM EXPOSURE:
May cause mechanical irritation.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation exposure may cause asthma.
PHYSICAL PROPERTIES
Melting point: >1116C
Density: 5.5g/cm
Solubility in water: none
ENVIRONMENTAL DATA

NOTES
Depending on the degree of exposure, periodic medical examination is indicated. Do NOT take working clothes home. Anyone who has shown symptoms of asthma due to this substance should avoid all further contact. 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.
