Abstract: The subject invention is silo explosion door serving as a safety protection apparatus to prevent damage resulting from an explosion within a silo from internally generated gaseous pressures. The invention is structured as an automatically actuated door mechanism that opens solely by the internal pressure generated against the inside areas of the door, and in this inventive application the door is equipped with an elastomeric frame that encompasses the perimeter of the door. This elastomeric frame is engineered and designed to have a specified internal resistance, as governed by its shape and modules of elasticity, which when exceeded by the internal pressure within the silo permits the door to be forced and ejected outwardly away from the silo, thereby permitting the escape of internal pressure.
