When exposed to air, white phosphorus spontaneously oxidizes to phosphorus pentoxide and hydrolyzes in water to form potentially corrosive phos-phoric acid, capable of producing chemical injury in tissues. It continues to burn until deprived of oxygen and, if extinguished with water, can later reignite if the particles dry out and are exposed again to the air.
