DARK BROWN OR BLACK SOLID.

Occupational exposure limits
TLV: asphalt (bitumen) fume as benzene-soluble aerosol, 0.5 mg/m³ as TWA; A4; (ACGIH 2003).
MAK not established.

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

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