It reacts with moisture to give phosphine, a flammable and poisonous <br />gas. Normally, phosphine will spontaneously ignite upon contact with air. If there is an excess of water, the phosphine fire will not normally <br />ignite any surrounding combustible material. (REACTIVITY, 2003) <br />Fire Hazard <br />Releases toxic fumes on exposure to moist air, water, or acids. Decomposes to produce phosphine gas. Avoid water, dilute mineral acids, <br />dilute or concentrated hydrochloric acid. Stable when dry. Avoid moist air. (EPA, 1998) <br />Fire Fighting <br />Wear self-contained breathing apparatus when fighting fires involving this material. If contact with the material is anticipated, wear full <br />protective clothing. <br />Do not use water or foam. Small fires can be extinguished with dry chemical, soda ash, or lime. Large fires -- withdraw from area and let <br />fire burn. Move container from fire only if you can do it without risk. (EPA, 1998) <br />Protective Clothing <br />For emergency situations, wear a positive pressure, pressure -demand, full facepiece self-contained breathing apparatus (SCBA) or <br />pressure- demand supplied air respirator with escape SCBA and a fully -encapsulating, chemical resistant suit.

Because material recommendations for chemicals in the same classification will generally, but not always, be appropriate, use <br />caution when following these recommendations. (NOAA, 1991) <br />Non -Fire Response <br />Do not use water. Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Keep <br />material dry. (© AAR, 2003) <br />Health Hazard <br />Acute toxicity occurs primarily by the inhalation route when aluminum phosphide decomposes into the toxic gas, phosphine. The human <br />median lethal dose for aluminum phosphide has been reported to be 20 mg/kg. Rated as super toxic: probable oral lethal dose is less than <br />5 mg/kg or less than 7 drops for a 70 kg (150 Ib.) person. (EPA, 1998) <br />Properties <br />Melting Point: Does not melt or decompose at temperatures up to 1832° F. (EPA, 1998) <br />6/12/2007 Printed from CAMEO Page 1 <br />
