Hazard Predictions

Sodium hydride reacts with alkynes to form corrosive and strongly basic sodium alkyne salts (Klemm, A., Hartmann, G. and Lange, L. 2000. Sodium and Sodium Alloys. Ullmann's Encyclopedia of Industrial Chemistry. (Online)).

Acetylene and cesium hydride react violently at low temperatures if moisture is present, or at slightly elevated temperatures if dry. This reaction may produce flammable H2 gas (J. W. Mellor, 1946. Mellor's Comprehensive Treatise on Inorganic and Theoretical Chemistry. Vol. 2, pp. 483. Longmans, Green and Co Ltd.).

Several complex reducing agents consisting of combinations of NaH with transition metal salts are active hydrogenation catalysts and react with unsaturated hydrocarbons to produce saturated hydrocarbons (Sullivan, E. and Wade, R. 1980. Hydrides. Kirk-Othmer Encyclopedia of Chemical Technology, 3rd ed. John Wiley & Sons, Inc.).
