Explovent explosion and pressure relief panels are engineered to be lightweight and fully calibrated for quick release at very low pressures. Explovent panels are testable at any time, and unlike blowout siding, Explovent is resettable after an event. In addition to meeting NFPA 68, Explovent conforms to IFC section 911 and all building codes.

Dust Explosions • Explosion hazards exist when all four conditions needed for a deflagration can occur within an enclosure – whether it is a room, building, container, or piece of equipment. • Most dust explosions originate inside pieces of equipment or containers. Fires and Explosions often occur in the following types of:

The review of gas explosion venting data and modeling focuses on the effect of equipment and structural obstacles in the vented enclosure. These obstacles can cause the vented explosion pressures to be many times as large as the pressure developed without obstacles for the same gas mixture, vent area, and ignition conditions.
