Description
This unit of competency covers the skills and knowledge required to control corrosion in plant, equipment and/or pipelines (plant) by the use of chemical or biological controls.This unit of competency applies to operators who are required to monitor plant for signs of corrosion, monitor the concentration of inhibiting chemicals or similar, and maintain an appropriate dosing regime in order to control the rate of corrosion.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.Corrosion typically refers to any electrochemical process leading to the decay of metal. However, this competency may also be contextualised and applied to decay processes in non-metals.No licensing, legislative or certification requirements apply to this unit at the time of publication.
