GERT8000-HB12 Iss 9
Duties of the engineering supervisor (ES) or safe work leader (SWL) in a possession
Synopsis
You will need this handbook if you carry out the duties of the ES or SWL in a possession.
Summary Of Changes
It is no longer permitted for work in connection with isolations of the AC or DC electrification systems to begin before the work-site marker boards are in position, and the wording in section 3.3 has been changed to remove reference to this being allowed. It has also been reworded to make it clear that no other work can commence within the work site until the person in charge of the possession (PICOP) has told the ES that the work site has been granted.
Section 6.9 is a new section describing the actions necessary when a controller of site safety (COSS), designated person (DP) or machine controller (MC) requests line protection for work to be carried out on a rail vehicle.
Section 7.8 has been renamed ‘manually controlled level crossing’ to remove gender-specific language.
