TIN PHOSPHIDE

Chemical properties

white powder(s); -100 mesh of 99.5% purity [CER91] [AES93]

General Description

A silver-white mass or lump solid.

Reactivity Profile

TIN PHOSPHIDE is a reducing agent. TIN PHOSPHIDE slowly generates flammable or noxious gases in contact with water. Reacts quickly upon contact with acids to give the very toxic gas phosphine. Can react vigorously with oxidizing materials.

Health Hazard

Highly toxic: contact with water produces toxic gas, may be fatal if inhaled. Inhalation or contact with vapors, substance or decomposition products may cause severe injury or death. May produce corrosive solutions on contact with water. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control may cause pollution.

Fire Hazard

Produce flammable and toxic gases on contact with water. May ignite on contact with water or moist air. Some react vigorously or explosively on contact with water. May be ignited by heat, sparks or flames. May re-ignite after fire is extinguished. Some are transported in highly flammable liquids. Containers may explode when heated. Runoff may create fire or explosion hazard.

Safety Profile

A flammable solid. Reacts with moisture or acid fumes to liberate highly toxic phosphine gas. When heated to decomposition it emits toxic fumes of POx. See also PHOSPHINE, PHOSPHIDES, and TIN COMPOUNDS.
