<p>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 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.</p> |
