Elements and Performance Criteria

1. Identify nature of corrosion
   • Inspect object
   • Observe service environment and note likely causes of, and vulnerability to, corrosion
   • Identify the type of corrosion present or likely to occur
2. Interpret surface preparation and coating specification
   • Identify surface preparation method specified
   • Identify prepared surface specification
   • Identify protection method specified
   • Identify finished specification of protected surface
3. Confirm appropriateness of specification
   • Compare specification with existing or likely corrosion
   • Confirm that the specification is appropriate for the situation
   • Clarify any discrepancies between specification and expected treatment and take appropriate action
4. Monitor treatment process
   • Identify hazards arising from the preparation and protection treatments
   • Implement appropriate hazard controls
   • Monitor the progress of the treatment
   • Recognise situations which might require a change to hazard controls or specifications
   • Take the required actions to resolve the identified situations

Evidence Required

The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria required skills and knowledge range statement and the Assessment Guidelines for the Training Package
Overview of assessment	Assessment of this unit should include demonstrated competence on actual plant equipment structures or similar in a work environment The unit will be assessed in as holistic a manner as is practical and may be integrated with the assessment of other relevant units of competency Assessment will occur over a range of situations which will include disruptions to normal smooth operation This unit of competency requires an application of the knowledge contained in the use of the corrosion control systems and their integral equipment to the level needed to maintain control and recognise and resolve problems
Critical aspects for assessment and evidence required to demonstrate competency in this unit	Competence must be demonstrated in the ability to recognise and analyse potential situations requiring action and then in implementing appropriate corrective action The emphasis should be on the ability to stay out of trouble rather than on recovery from a disaster Consistent performance should be demonstrated In particular look to see that early warning signs of potential problems are recognised the range of possible causes can be identified and analysed and the most likely cause determined appropriate action is taken to ensure a timely resolution to meet requirements
Context of and specific resources for assessment	Assessment will require access to an operating plant over an extended period of time or a suitable method of gathering evidence of operating ability over a range of situations Assessment will occur over a range of situations which will include disruptions to normal smooth operation Simulation or case studiesscenarios may be required to allow for timely assessment of parts of this unit of competency Simulation should be based on the actual plant and will include walkthroughs of the relevant competency components A bank of scenarioscase studieswhat ifs and questions will be required to probe the reasoning behind observable actions
Method of assessment	Assessment must satisfy the endorsed assessment guidelines of the Manufacturing Training Package Assessment methods must confirm consistency and accuracy of performance over time and in a range of workplace relevant contexts together with application of underpinning knowledge Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure its correct interpretation and application Assessment may be applied under project related conditions real or simulated and require evidence of process Assessment must confirm a reasonable inference that competency is able not only to be satisfied under the particular circumstance but is able to be transferred to other circumstances Assessment may be in conjunction with assessment of other units of competency where required
Guidance information for assessment	Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed

Range Statement

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Codes of practice/standards	Where reference is made to industry codes of practice, and/or Australian/international standards, the latest version must be used
Service environment	Service environment refers to: the environment in which the systems or units (object) the technician is responsible for operate and may be a plant/factory area, a well head, major infrastructure or pipeline covering thousands of kilometers
Corrosion	Corrosion typically refers to: any electrochemical process leading to the decay of metal. It may also be applied to decay processes in non-metals if appropriate
Appropriate action	Appropriate action may include: determining problems needing action determining possible fault causes rectifying problem using appropriate solution within area of responsibility following through items initiated until final resolution has occurred reporting problems outside area of responsibility to designated person
Procedures	Procedures may be written, verbal, computer-based or in some other form. They include: all work instructions standard operating procedures formulas/recipes batch sheets temporary instructions any similar instructions provided for the smooth running of the plant For the purposes of this Training Package, 'procedures' also includes good operating practice as may be defined by industry codes of practice (e.g. Responsible Care) and government regulations
Health, safety and environment (HSE)	All operations to which this unit applies are subject to stringent health, safety and environment 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
Hazards	Hazards may include: dust, mists, fumes and waste disposal issues
