ACUTE HEALTH HAZARDS & ADVICE:

ARMOURSEAL 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.

RECOMMENDED PROTECTIVE CLOTHING:

Overalls, Goggles/Visor, Gloves and Closed Safety Boots when handling hot products.

TRANSPORTATION Not classified as hazardous for transportation
