Abstract
Improved, non-fragmenting, high efficiency vent apparatus (10, 78) are provided for protecting a structure (12) from potentially damaging or destructive abnormal pressure conditions. The apparatus (10, 78) is positioned in covering relationship to a vent opening (14) formed in the structure (12), and generally includes a burst member (16) and a tab assembly (18) equipped with a series of tabs (56); the tabs (56) bend or buckle to a burst member-clearing position when the vent apparatus (10, 78) experiences an abnormal pressure condition, thereby permitting rapid opening of a central section of the burst member (16) to thus protect structure (12). The burst member (16) may be of domed or flat construction, and can be in the form of a quadrate panel or any other desired shape.
