A pressure relief door assembly (300) includes a pressure relief door (310), a pressure-actuated latch (320), and a temperature-actuated lock (370). The latch (320) is disposable in each of a latched configuration (to retain the pressure relief door (310) in a closed position (312)) and an unlatched configuration (to allow the pressure relief door (310) to move into an open position). The lock (370) is disposable in each of an unlocked configuration (to allow the pressure relief door (310) to move into the open position when the latch (320) is in its unlatched configuration) and a locked configuration (e.g., to lock the latch (320) in its latched configuration, to lock the pressure relief door (310) in its closed position (312), or both). The lock (370) may include a bimetallic coil (378), 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 (320) to retain the latch (320) in its latched configuration.
