A movie of impure phosphine igniting spontaneously in air. The gas was generated by adding sodium phosphide on aluminium foil to water. The main impurity, diphosphane, was responsible for spontaneous combustion. Phosphine and diphosphane are both very toxic.
Phosphine is used as a fumigant. Its most common use is for killing rodents and other pests in grain elevators.
