GU-624 – Licensing Guidelines – PDO

The Permit to Work (PTW) system is in use throughout the Company. One of the fundamental principles of the system is that all persons involved in using it should be licensed in their role; this licensing being in addition to the successful completion of the relevant training course(s).

The PTW System Procedure (PR-1172) provides the outline description and minimum requirements of the licensing system. The Procedure gives scope to apply a wide variety of methods to conduct the licensing assessment, detailing only the main reasons for the licensing system, the areas to be addressed, and who should authorize the licenses.

This guideline is supplementary to the PTW System Procedure, providing more detail for those involved in conducting assessments and authorizing licenses.
