Abstract
A barrier for containing an explosion in a room or the like. The barrier is a structural panel comprising a base sheet, a plurality of truncated polyhedral elements secured to and projecting from the base sheet, and a face sheet covering and secured to the truncated apexes of the polyhedral elements. The face sheet is constructed to separate from the polyhedral elements to expose them in the event of an explosion. Each polyhedral element is constructed to collapse in the event of an explosion, is filled with a liquid, and has an opening therein that is closed by a closure device that is openable or removable in response to the collapse of the polyhedral element caused by an explosion. The openings in the polyhedral elements are of a size to effect a misting action of the liquid therein when it is ejected from the openings by the collapse of the polyhedral elements caused by the explosion. The liquid mist serves to absorb and dissipate the heat and energy of the explosion.
