ABSTRACT:
A handle operated door latching mechanism for moving upper and lower latch members into and out of engagement with a latching surface of an enclosure which becomes distorted by internal gas pressure to pull the latch members away from the latching surface, has one latch member formed longer than the other to permit release of the latching surface by the shorter latch member and limited opening of the door for exhausting the internal gas while the longer latch member remains in engagement with the latching surface to maintain the door substantially closed.
