    en.wikipedia.org/wiki/Trapped-key_interlocking

    The sliding bolt, when extended, mechanically prevents operation of a switch, valve, gate, or other device. Many variations exist, with different shapes of interlock bolt and multiple lock cylinders on an interlock. A significant feature of the interlock is that the key is held or trapped in one position of the lock.

    An SIS performs a safety instrumented function (SIF). The SIS is credited with a certain measure of reliability depending on its safety integrity level (SIL). The required SIL is determined from a quantitative process hazard analysis (PHA), such as a Layers of Protection Analysis (LOPA). The SIL requirements are verified during the design ...

    Protection through the use of safety layers. A process plant shutdown system is a functional safety countermeasure crucial in any hazardous process plant such as oil and gas production plants and oil refineries. The concept also applies to non-process facilities such as nuclear plants. These systems are used to protect people, assets, and the ...

    Railway interlocking is of British origin, where numerous patents were granted. In June 1856, John Saxby received the first patent for interlocking switches and signals. [2] [3]: 23–24 In 1868, Saxby (of Saxby & Farmer) [4] was awarded a patent for what is known today in North America as “preliminary latch locking”.

  7. Safety engineering - Wikipedia

    en.wikipedia.org/wiki/Safety_engineering

    Safety engineering is an engineering discipline which assures that engineered systems provide acceptable levels of safety. It is strongly related to industrial engineering/systems engineering, and the subset system safety engineering. Safety engineering assures that a life-critical system behaves as needed, even when components fail.
