ACUTE HEALTH HAZARDS & ADVICE

Bituminous products present no acute health hazard at ambient temperature. However, as these materials are normally handled at elevated temperatures when their physical state changes to a liquid, the bitumens present in these products give off fumes which are undesirable to inhale as very small quantities of HYDROGEN SULPHIDE may be present in the bitumen.
