ELECTRICAL ABILITY PERMIT 7.1 GENERAL When a Contractor's employee works in TI plant as an electrician, the contractor must prove his/her electrical competence and electrical safety knowledge to the satisfaction of the Site Maintenance Superintendent and the Electrical Supervisor. All permanent employee and permanent contracted personnel working on electrical installation must obtain an Electrical Ability Permit from Sr. Electrical Authorized Person. Each employee (permanent or contracted) who works in electrical installation in Total Indonesie Sites has to know the content of this SOP 03-006. The person shall follow the electrical training before getting his / her ability permit and shall pass/ succeed the training test. The validity period of the ability permit is 3 (three) years and could be extended every other 3 (three) years. Extension of permit could only be issued if the person has followed the refreshment training and pass/ succeed the training test. The ability permit is only valid for specific site, type of work, etc., as indicated on the ability permit. Consequently, each person who moves to other site shall obtain the new ability permit upon request to the Electrical Supervisor. The ability permit is strictly personal and non-transferable to other persons. The holder must carry his/ her ability permit all the times during working hours or have it easily available. In the event of loss of his/ her ability permit document, the Electrical Supervisor should be informed immediately. The ability permit does not follow the order of hierarchy. It concerns only the safety consideration of electrical operations. The ability permit does not authorize the holder to perform an operation or works covered by it on his/ her own initiative. Each Supervisor could ask ability permit for his/ her subordinates to Sr. Electrical Authorized Person by mentioning the capability and competence of the proposed holders. Site Sr. Electrical Supervisor will keep the record of all the Electrical Authorized Persons at his/her site and inform Sr. Electrical Authorized Person for any change.
