Unit of competency
Modification History
Release 1. Supersedes and is equivalent to PMASUP346A Control corrosion
Application
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.

Foundation Skills
This section describes those language, literacy, numeracy and employment skills that are essential to performance.
Foundation skills essential to performance are explicit in the performance criteria of this unit of competency.
Range of Conditions
This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included. |
|
Regulatory framework |
The latest version of all legislation, regulations, industry codes of practice and Australian/international standards, or the version specified by the local regulatory authority, must be used, and include one or more of the following:
All operations to which this unit applies are subject to stringent health, safety and environment (HSE) requirements, which may be imposed through state/territory or federal legislation, and these must not be compromised at any time. Where there is an apparent conflict between performance criteria and HSE requirements, the HSE requirements take precedence. |
Procedures |
All operations must be performed in accordance with relevant procedures. Procedures are written, verbal, visual, computer-based or in some other form, include one or more of the following:
|
Hazards |
Hazards include one or more of the following:
|
Routine problems |
Routine problems are predictable and have known solutions and include one or more of the following:
|
Non-routine problems |
Non-routine problems are unexpected problems, or variations of previous problems and must be resolved by applying operational knowledge to develop new solutions, either individually or in collaboration with relevant experts, to:
Operational knowledge includes one or more of the following:
|
Corrosion control system |
This unit of competency includes all such items of equipment and unit operations which form part of the corrosion control system, including as appropriate to the facility:
|
Work area |
Work area refers to the systems or units the technician is responsible for. Depending on the organisation and context it might be a plant area, a well head or pipeline covering thousands of kilometres. |
Corrosion inhibitors |
Corrosion inhibitors include or more of the following:
|
Inhibitor dosing |
Inhibitor dosing includes one or both of the following:
