- Trapped_key_interlocking abstract "Trapped key interlocking utilizes locks and keys for sequential control of equipment and machinery to ensure safe operation. Trapped key interlocks are widely used to ensure safe access to potentially live or dangerous plant or equipment in an industrial setting.A safe sequence of operations is enabled through transfer of keys that are either trapped or released in a predetermined order. For example, a key is used to isolate a power source (circuit breaker or supply valve), this key is then released and can then be used to gain access through a gate or door to a high risk area by inserting it into an access lock. The key will then remain trapped until the gate or door is closed. A personnel or safety key can be released from the access lock, this ensures that the gate or door can not be closed and the initial key released until this personnel or safety key is returned. This provides increased operator safety.Trapped key interlocks were used in the 1890s, in the French railway system to control track switching operations. Both the Englishman James Harry Castell (1880-1953) and the American R. L. Kirk developed trapped key interlocking systems, and such systems are often referred to as "Castell" or "Kirk" key interlock systems. Both worked in the power generation and distribution industries in the early part of the 20th Century, and both pioneered the use of trapped key interlock for switchgear control. Trapped key interlocks can be found in many industrial settings including electrical utilities, railway, petroleum, and chemical plants as a response to occupational safety and health legislation.".
