IMPORTANT DATA
Physical State; Appearance Routes of exposure
GREY POWDER OR REDDISH-SILVERY CRYSTALS. The substance can be absorbed into the body by inhalation.
Chemical dangers Inhalation risk
The substance decomposes on heating producing toxic gases A harmful concentration of airborne particles can be reached
and irritating fumes including hydrogen sulfide and sulfur oxides. quickly when dispersed, especially if powdered.
Reacts with strong oxidants.
Effects of short-term exposure
Occupational exposure limits May cause mechanical irritation.
TLV: (as cobalt) 0.02 mg/m3 as TWA; A3; BEI issued; (ACGIH
2004). Effects of long-term or repeated exposure
MAK: (inhalable fraction) Sah; Carcinogen category: 2; Germ Repeated or prolonged contact may cause skin sensitization.
cell mutagen group: 3A; (DFG 2003). Repeated or prolonged inhalation exposure may cause asthma.
PHYSICAL PROPERTIES
Melting point: >1116/C Solubility in water: none
Density: 5.5 g/cm3
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.
