explosive mixtures explosion is substance from one state , after a physical change or chemical change , suddenly turned into another state and release tremendous amounts of energy , and light and heat or mechanical work . Only talked about the explosion of an explosive mixture , that is all the flammable gas , vapor and dust with air to form an explosive mixture explosion . Such explosion needs may occur only have three conditions : first , the presence of explosive substances or flammable substances ; Second, there must be combustion substances , the oxygen in the air ; Third , is also there to ignite source ( such as spark , arc , and dangerous temperature, etc. ), which provides the energy necessary to ignite the mixture .
