Explosion vent of the distribution box
Explosion venting is a passive method that uses an engineered weak point (a vent panel) to open at a low set pressure (Pstat). Often the most cost-effective explosion protection methods, explosion vent panels relieve a deflagration's pressure and flames from the vessel in order to keep its total pressure below its design pressure. This allows the pressure wave to be safely released without damaging the equipment. In the event of a deflagration the vents provide a rapid and unrestricted opening at a predetermined burst pressure (Pstat) allowing combustion gases to expand and flow. An explosion vent or rupture panel is a safety device to protect equipment or buildings against excessive internal, explosion-incurred pressures, by means of pressure relief.
