ACGIH: Not classifiable as a human carcinogen: Inadequate data on which to classify

           the agent in terms of carcinogencity in humans/animals.



SYMPTOMS OF OVEREXPOSURE:

            Inhalation: Repeated prolonged exposure to trivalent compounds may cause delayed

            effects involving the respiratory system.

            Eye Contact: Mechanical irritation to the eye may occur such as watering, reddening

            do to exposure to fines.

            Skin Contact: Expected to be non irritating.

            Ingestion: Considered to be non-irritating, non-toxic if swallowed.
