PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
GREY-TO-BLACK POWDER.

Physical dangers

Chemical dangers
Reacts violently with strong oxidants. This generates fire and explosion hazard.

Formula: WC
Molecular mass: 195.9
Boiling point: 6000°C
Melting point: 2780°C
Density: 15.6 g/cm³
Solubility in water: none

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation. Effects of short-term exposure May cause mechanical irritation.	Inhalation risk Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed. Effects of long-term or repeated exposure Repeated or prolonged inhalation of dust particles may cause effects on the lungs. This may result in fibrosis.

EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation.

Effects of short-term exposure
May cause mechanical irritation.

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.

Effects of long-term or repeated exposure
Repeated or prolonged inhalation of dust particles may cause effects on the lungs. This may result in fibrosis.

OCCUPATIONAL EXPOSURE LIMITS
TLV: (respirable fraction): 3 mg/m³, as TWA

ENVIRONMENT
Environmental effects of the substance have been adequately investigated, but no significant effects have been found.

NOTES
Health effects of exposure to the substance have not been investigated adequately. This material is often used in conjunction with other substances such as cobalt compounds. Pneumoconiosis has occurred in exposed persons. The responsible agent is not yet clear.
