Acetylenic compounds with replaceable acetylenically bound hydrogen atoms must be kept out of contact with copper, silver, magnesium, mercury, or alloys containing them, to avoid formation of explosive metal acetylides ("Chemical Intermediates", 1972 Catalogue, 158, Tamaqua (Pa.), Air Products and 365betÓéÀÖ Inc., 1972; Dangerous Substances: Guidance on Fires and Spillages, London, HMSO, 1972, Sect. 1, p. 27).
Powdered cobalt incandescently decomposes acetylene on contact, posing a fire hazard (J. W. Mellor, 1942. Mellor's Comprehensive Treatise on Inorganic and Theoretical Chemistry. Vol. 14, pp. 513. Longmans, Green and Co Ltd.).
