Trapped key interlocks

Technology Sourcebook Default
September 14, 2015

Enhancing lockout/tagout procedures, KIRK trapped key interlocks ensure energy isolation procedures cannot be circumvented. Once the key is removed from the interlock, the equipment cannot be re-energized until the uniquely coded KIRK key is re-entered into the sequence. A time delay unit can be added to allow hazardous energy to dissipate prior to allowing access.
