OLE Films The four films on this page have been developed by the standardised task team at the request of the OLE Competence Development Group. The Overhead Line Equipment CDG is responsible for all OLE technical and safety training and assessment material. It has representatives from PD&T, STE, IP, Maintenance (Delivery Units and Works Delivery), Overhead Condition Renewals team, EPDG, and the RAM teams. The films targeted at the role of the Authorised Person cover switching, testing and the application and removal of short portable earths. (We hope to develop an additional film on the use of long blue earths). The key reason for their development was to stem the number of isolation irregularities that occur each year despite the life-saving rules. +22 ← Back
