fail-safe         
  • Railway semaphore signals. "Stop" or "caution" is a horizontal arm, "Clear to Proceed" is 45 degrees upwards, so failure of the actuating cable releases the signal arm to safety under gravity.
  • An aircraft lights its [[afterburner]]s to maintain full power during an [[arrested landing]] aboard an [[aircraft carrier]]. If the arrested landing fails, the aircraft can safely take off again.
  • Globe control valve with pneumatic diaphragm actuator. Such a valve can be designed to fail to safety using spring pressure if the actuating air is lost.
¦ adjective
1. causing a piece of machinery to revert to a safe condition in the event of a breakdown.

In engineering, a fail-safe is a design feature or practice that in the event of a specific type of failure, inherently responds in a way that will cause minimal or no harm to other equipment, to the environment or to people. Unlike inherent safety to a particular hazard, a system being "fail-safe" does not mean that failure is impossible or improbable, but rather that the system's design prevents or mitigates unsafe consequences of the system's failure.
