Like strong acids, weak acids react vigorously with alkali metals to produce H2 gas, which is likely to be ignited by the heat of reaction.
Hydrofluoric acid reacts with nearly all non-noble metals and alloys, dissolving the metal and producing flammable hydrogen gas (Aigueperse, J. 2000. Fluorine Compounds, Inorganic. Ullmann's Encyclopedia of Industrial Chemistry. Wiley-VCH Verlag GmbH & Co. KGaA. (Online)).
Sodium reacts vigorously with HF, producing flammable H2 gas (Dickinson, F. 1961. Mellor's Comprehensive Treatise on Inorganic and Theoretical Chemistry. Vol. 2, Supplement 2, p. 452. Longmans, Green and Co Ltd.; Mellor, J.W. 1941. Mellor's Comprehensive Treatise on Inorganic and Theoretical Chemistry. Vol. 2, p. 469-470. Longmans, Green and Co Ltd.).
Potassium reacts explosively with boric acid (Dickinson, F. 1963. Mellor's Comprehensive Treatise on Inorganic and Theoretical Chemistry. Vol. 2, Supplement 3, p. 1571. Longmans, Green and Co Ltd.).
