BRAND NAME ARMOURSCREED AS 50

COMPOSITION

A blend of polymer modified bitumen with Rubber Granules - Aggregate - Fibres - Extender & Adhesion Agent.

SAFE HANDLING PRECAUTIONS:

· Do not exceed the maximum safe heating temperature.

· Do not allow the hot material to come into contact with water as the product will

react violently.

· Always wear the recommended protective clothing - see below.

ACUTE HEALTH HAZARDS & ADVICE:

ARMOURSCREED-AS50 presents 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 of 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 product.

TRANSPORTATION Not classified as dangerous for transportation.
