Description
This unit describes the skills and knowledge required to control corrosion in a plant, its equipment and/or plant pipelines using chemical or biological controls. This unit includes all equipment and operations that form part of the corrosion control system. Corrosion typically refers to any electrochemical process leading to the decay of metal. This unit may also be contextualised and applied to decay processes in non-metals.This unit applies to autonomous operators who are required to demonstrate a significant understanding of the process and the equipment operation in a plant with local control, or in liaison with the control-room operator in a plant with a centralised control panel.This unit 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. No licensing or certification requirements exist at the time of publication. Relevant legislation, industry standards and codes of practice within Australia must be applied.
