Application
The unit applies to technicians who are responsible for preparing and protecting an object to a provided specification. They will be able to inspect the object and confirm that the specification is appropriate for this application. This unit is not intended to provide sufficient knowledge and skills to develop a specification. Generally the technician would operate independently or as part of a team and should be capable of performing all parts of this unit. At all times they would be liaising and cooperating with other members of the team. |

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 studies/scenarios 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 'walk-throughs' of the relevant competency components. A bank of scenarios/case studies/what 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 |
