In order to help the platform reconstruction teams to identify the Safe Working Limits of the Permanently Earth Sections (PES) on the Liverpool Lime Street Re-modelling and Re-Signalling Project, Buckingham Group Contracting Ltd as Principal Contractor have been using Magnetic Blue flashing LED lights (Night-searcher Pulsar Pro rechargeable 9 function LED warning lights) which attach to OLE structures as a visual reminder.
Where there is no OLE or Signal structure near the demarcation limits, they act as a visual aid/reminder to COSS’s/Machine controllers that they are nearing the limit of an isolation.
On the occasion the Blue LED lights cannot be attached to a structure the other option is to attach the lights to an Exclusion Zone board which can be placed at track level or on the platform.
