A pressure relief door assembly includes a pressure relief door, a pressure-actuated latch, and a temperature-actuated lock. The latch is disposable in each of a latched configuration (to retain the pressure relief door in a closed position) and an unlatched configuration (to allow the pressure relief door to move into an open position). The lock is disposable in each of an unlocked configuration (to allow the pressure relief door to move into the open position when the latch is in its unlatched configuration) and a locked configuration (e.g., to lock the latch in its latched configuration, to lock the pressure relief door in its closed position, or both). The lock may include a bimetallic coil, that when exposed to a temperature that satisfies a temperature threshold, expands a sufficient amount to engage a locking pin with a corresponding portion of the latch to retain the latch in its latched configuration.
