The pressure relief door of claim 1, wherein the tube includes a pair of thumbs, a pair of diametrically opposed first slots located at the first end of the tube, and a pair of diametrically opposed second slots located at the second end of the tube, one of the thumbs being attached to one of the pins and extending through the first slots, and the other of the thumbs being attached to the other of the pins and extending through the second slots. 3. The pressure relief door of claim 2, wherein the pressure relief door is moveable from a closed position to an open position, and from the open position to the closed position. 4. The pressure relief door of claim 3, wherein the pressure relief door is adapted to be installed within a structure, wherein when the pressure relief door is in its closed position, the exterior side of the panel is substantially flush with an exterior surface of the structure, the lock mechanisms are engaged with an interior surface of the structure, and the pressure relief latches are engaged with the interior surface of the structure. 5. The pressure relief door of claim 4, wherein when the pressure relief door is moved from its closed position to its open position, the pressure relief latches are disengaged with the interior surface of the structure, while the lock mechanisms remain engaged with the interior surface of the structure. 6. The pressure relief door of claim 4, wherein each of the hinges includes a tubular portion having a hole formed axially therein. 7. The pressure relief door of claim 6, wherein when the pressure relief door is moved to its open position, the hinges pivot in a first direction and are stopped by the stops of the second mounting brackets, and the holes of the tubular portions of the hinges align with the tubing, the compression springs expand and push the corresponding pins through the corresponding holes of the hinges, and each of the corresponding thumbs stop at first ends of each of the corresponding pairs of the first and second slots of the tube to retain the pins engaged and locked with the corresponding one of the hinges. 8. The pressure relief door of claim 7, wherein the thumbs are adapted to be moved axially with respect to the tube and toward one another until the thumbs stop at second ends of the corresponding pair of first and second slots, thereby enabling the pins to disengage and clear the corresponding holes of the tubular portions of the hinges, and further enabling the hinges to pivot in a second direction opposite the first direction and away from the pins so as to enable to move the pressure relief door from its open position to its closed position. 9.
