Freebase

  1. Fail-safe

    A fail-safe or fail-secure device is one that, in the event of failure, responds in a way that will cause no harm, or at least a minimum of harm, to other devices or danger to personnel. "Fail-safe[ty]" should not be confused with "fail-secur[ity]." A fail-secure component of a system secures that system in the event of a failure either of that component or elsewhere in the system. For example, during a failure of an ingress-egress control system, e.g., a user propping a door open somewhere in a building, a fail-secure lock will close, lock, and remain locked even when a user attempts to unlock it with the key that the user usually employs. In such a case, an independent release, such as a reboot or disarming of the securing mechanism, is required. In contrast, a component may be considered fail-safe even if its failure does not secure the system. For example, if a door locked from the inside is left unlocked or is unlocked at the wrong time, it has failed, the door may be fail-safe if its being unlocked does not open it or attract additional attention to its unlocked state.
