Key Cabinet Engraving
Each interlocked system has a dedicated engraved tag location within the key cabinet. During periods of normal operations, all interlock system ‘permit’ (initiating) keys are visually displayed within the cabinet in dedicated locations. Each key cabinet tag is engraved with the relevant piping package data – this same data is also replicated on each system key. When the key is removed, a ‘Visual Alert’ tag is revealed providing details of the key which has been issued, its designated location, and the words ‘WORK IN PROGRESS’. Control Room staff have clear and easy indication of work status at any time. Key cabinets can also accommodate mimic diagrams as specified by the customer.
