ABSTRACT:
A combination manway cover and pressure relief apparatus (2) for a tank (4) having a manway opening (14) and containing a fluid. A body (12) covers the manway opening and is guided and biased along a substantially vertical, linear path (16). The body is guided along the path by bolts (18) which pass through a plurality body, gasket and flange bolt holes (22, 23, 24). The weight of the body biases the body along the path toward the manway opening. Pressure relief for the tank is provided when the fluid pressure within the tank moves the body away from the manway opening.
