Explosion Venting is the most tried and tested form of explosion relief. The explosion vent panel is designed to rupture safely as a result of an over-pressure. The deflagration pressure is able to escape first through the vent opening and then into the atmosphere. This prevents the explosion from gaining momentum and having violent consequences.
Dec 15, 2014· For example, the April 2013 ammonium nitrate explosion that occurred in West, Texas exposed a problem with regulation and storage of hazardous materials and related separation distances around the facilities.
