Corrosive and/or toxic; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Fire will produce irritating, corrosive and/or toxic gases. Reaction with water may generate much heat that will increase the concentration of fumes in the air. Contact with molten substance may cause severe burns to skin and eyes. Runoff from fire control or dilution water may cause pollution.

---|---|---|---|---|---|
rat | LD50 | oral | 160mg/kg (160mg/kg) | American Industrial Hygiene Association Journal. Vol. 30, Pg. 470, 1969. |
Reported in EPA TSCA Inventory.
Poison by ingestion. A corrosive irritant to skin, eyes, and mucous membranes. When heated to decomposition it emits toxic fumes of VOx and Cl−. See also VANADIUM COMPOUNDS and HYDROCHLORIC ACID.
Except for acetic anhydride (un1715), that is flammable, some of these materials may burn, but none ignite readily. May ignite combustibles (wood, paper, oil, clothing, etc.). Substance will react with water (some violently), releasing corrosive and/or toxic gases and runoff. Flammable/toxic gases may accumulate in confined areas (basement, tanks, hopper/tank cars, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water. Substance may be transported in a molten form.
