A product of combustion accompanied by the creation of gasses and heat is an explosion.. What creates an explosion is the rapid buildup of gas pressure. Detonation occurs so rapidly that oxygen in the air cannot participate in the reaction. Leaving it that many explosions have their own source of oxygen.. 1. Dust Explosion Fundamentals.
