Description
This unit of competency describes the skills and knowledge required to isolate and prepare a plant for maintenance work, maintain isolations, remove isolation and return a plant to service.This unit of competency applies to operators, maintainers and those in similar roles who are required to create and conduct isolations and de-isolations, and reinstate equipment in an industrial installation. The person will have detailed operational and process knowledge and may work alone or as part of a team. The person will usually report through to a permit co-ordinator, supervisor or central-control-room operator.Creation and implementation of the isolation requires appropriate consideration of known plant equipment and/or systems not functioning according to design. This typically includes but is not limited to passing valves, blocked lines, drains and system dead legs.No licensing, legislative or certification requirements exist at the time of publication. Relevant legislation, industry standards and codes of practice within Australia must be applied.
