Tablets react with moisture to produce phosphine gas, PH3, which has an autoignition temperature of 38 Celsius However, the presence of impurities, particularly diphosphine, often causes PH3 gas to ignite spontaneously at room temperature and to form explosive mixtures at concentrations greater than 1.8% by volume in air. The spontaneous ignition behaviour of PH 3 gas is very unpredictable. Continue reading »
