| Fail safe | Aerospace | Term for philosophy in the design of propulsion system hardware that seeks to avoid the compounding of failures; fail-safe design provisions ensure that the component (e.g., a valve element) will move to a predetermined "SAFE" position if electrical, pneumatic, or hydraulic power is lost.

| Fail safe | Business | 1: A condition whereby an electromechanical door lock reverts to the unlocked position in the event of a power failure, as opposed to fail secure, which defaults to a locked position. This feature is necessary for safety in life threatening situations, such as a fire. It is also required by most fire codes for commercial and public buildings. Any device or system that initiates an alarm or trouble indication in the event of an equipment failure or power loss. Also called fail soft. (references) | |
| 2: 1) Of a device, the capability to fail without detriment to other devices or danger to personnel. 2) Pertaining to the automatic protection of programs and/or processing systems to maintain safety when a hardware or software failure is detected in a system. 3) Pertaining to the structuring of a system such that either it cannot fail to accomplish its assigned mission regardless of environmental factors or that the probability of such failure is extremely low.

| Fail safe | Nuclear Energy & Physics | Refers to a principle of design by which, in the event of any failure in a system, the system takes up a safe condition. Source: European Union. (references) | |
| Fail safe | Physics | A property of a system in which failure is impossible. See safe fail. (references) | |
| Fail safe | Transportation | Normally structural design, rather than system, technique in which no crack can cause catastrophic failure of whole structure but is allowed to occur and be detected. Source: European Union. (references) | |
| Fail safe system | Aerospace | A system used to minimize risk in case of a malfunction. (references) | |
