Explosibility
Explosibility is the property of a material to undergo a rapid, exothermic chemical reaction that generates hot gases and a shockwave. It applies to gases and vapors mixed with air as well as to finely divided solids that can form explosive dust clouds. The concept emphasizes rapid pressure rise and a mechanical blast effect rather than heat alone.
Gases and vapors: The flammable range is defined by the lower and upper explosive limits (LEL and
Dusts: Combustible dusts can become explosive when dispersed as a cloud in air. Explosibility is assessed by
Influencing factors: Confinement, particle size, moisture, temperature, oxygen content, and the presence of inhibitors or catalysts
Hazard management: Industrial safety seeks to minimize risk through process design, adequate ventilation or inerting, thorough
Standards and assessment: Explosibility is evaluated using standardized laboratory tests and risk assessments. Guidance comes from
