This unit of competency covers the skills and knowledge required to examine an object for corrosion, confirm the appropriateness of any corrosion treatment and monitor the treatment process. The object may be any type of plant, equipment or structure in any service environment, such as a plant/factory area, a well head, an item of major infrastructure or a pipeline covering thousands of kilometres. This unit applies to situations where the corrosion is treated using a surface coating. Corrosion typically refers to any electrochemical process leading to the decay of metal but also includes decay processes in non-metals.This unit of competency applies to technicians. The technician will be required to examine substrates and the design of the object to be treated to determine the preparation and protection which might need to be applied and confirm that the treatment specification is appropriate and to monitor that treatment process. This unit of competency applies to an individual working alone or as part of a team or group and working in liaison with other shift team members and the control room operator as appropriate.No licensing, legislative or certification requirements apply to this unit at the time of publication.
