In that basic rule, there are 3 key ingredients (or sides). Thermobaric weapons exploit this principle by rapidly saturating an area with an easily combustible material and then igniting it to produce explosive force. By lighting TNT with fire, (lava, flint and steel), the TNT will start to blow up. Dusts have a very large surface area compared to their mass. Ignition temperature is the minimum temperature at which a material will burn or explode. Repairs took a year to complete. Many NPS sites interpret cultural resources and operate historic farming operations that use or generate materials that can spontaneously combust, such as manure piles or soiled straw. Below a certain value, the lower explosive limit (LEL), there is insufficient dust to support the combustion at the rate required for an explosion.

The rate or speed at which the reactants combine is high, in part because of the nature of the chemical reaction itself and in part because more energy is generated than can escape into the surrounding medium, with the result that the temperature of the reactants is raised to accelerate the reaction even more. In cases when fuel plays the role of a combustible material, the explosion is known as a fuel-air explosion. Dust explosions can occur where any dispersed powdered combustible material is present in high-enough concentrations in the atmosphere or other oxidizing gaseous medium, such as pure oxygen. Dust is defined as powders with particles less than about 500 micrometres in diameter, but finer dust will present a much greater hazard than coarse particles by virtue of the larger total surface area of all the particles.

Around the world, thousands of people get killed with the explosion of as cans every year. The researchers already knew that these explosions were caused by evaporating water vapor trapped inside the concrete. Due to chemical, biological, or physical processes, combustible materials self-heat to a temperature high enough for ignition to occur. The chain reaction produced from the ignited sugar dust particles produces energy.
