Asphalt oil composition is more complex, elements ranging from dozens of species, as many as hundreds. In addition to hydrocarbons (carbon and hydrogen) compounds, but also contains oxygen, sulfur, nitrogen, copper, nickel, vanadium and other elements, including sulfur, nitrogen, oxygen content higher. Petroleum bitumen generally does not explode under normal circumstances, but can explode under special conditions. On November 8, 1991, at 11 am, an emergency accident occurred in a melody road in Qujing, Yunnan Province. One person was killed and one was slightly injured on the spot.
