Hazard Predictions

• Flammable: Reaction products may be flammable
• Generates heat: Exothermic reaction at ambient temperatures (releases heat)

Lithium metal reacts slowly with dry nitrogen at room temperature to form flammable lithium nitride. This reaction mixture may ignite in the presence of water or oxygen (Wietelmann, U. and Bauer, R. J. 2000. Lithium and Lithium Compounds. Ullmann's Encyclopedia of Industrial Chemistry. (Online); Pascal, P. 1966. Nouveau Trait茅 de Chimie Min茅rale. Vol. 2, Part 1, p. 37. Masson et Cie.; Fritsch, Proc. 1st Int. Symp. Prev. Occup. Risks Chem. Ind., 208-211, Heidelberg, ISSA, 1970).

Sodium and potassium metal react with dry nitrogen in the presence of an electric discharge to form explosive metal nitrides and metal azides. Otherwise, there is no reaction between these metals and nitrogen gas (even when heated) (Eggeman, T. 2007. Sodium and Sodium Alloys. Kirk-Othmer Encyclopedia of Chemical Technology. John Wiley & Sons, Inc. (Online); Dickinson, F. 1961. Mellor's Comprehensive Treatise on Inorganic and Theoretical Chemistry. Vol. 2, Supplement 3, p. 1565. Longmans, Green and Co Ltd.).

Potassium and cesium react violently with Teflon equipment even under inert atmosphere; therefore, Teflon-coated stirbars or gaskets in equipment or valves should not be allowed to contact these metals (Burkhardt, E. R. 2006. Potassium and Potassium Alloys. Ullmann's Encyclopedia of Industrial Chemistry. (Online)).

Molten alkali metals react vigorously with carbon dioxide. CO2 should never be used to extinguish a metal fire (Dickinson, F. 1961. Mellor's Comprehensive Treatise on Inorganic and Theoretical Chemistry. Vol. 2, Supplement 2, p. 74, 84, 88; Vol. 2, Supplement 3, p. 440. Longmans, Green and Co Ltd.; Pascal, P. 1966. Nouveau Trait茅 de Chimie Min茅rale. Vol. 2, Part 1, p. 15. Masson et Cie.).
