Application
This unit involves the skills and knowledge required to find and rectify faults in process final control elements. It includes working safely, interpreting valve specifications, applying knowledge of final control elements operating parameters, conducting tests and repairs, and completing the necessary service documentation. Permits may be required for some work environments, such as confined spaces, working aloft, near live electrical apparatus and site rehabilitation. No licensing, legislative or certification requirements apply to this unit at the time of publication. |

Assessment Conditions
Assessors must hold credentials specified within the Standards for Registered Training Organisations current at the time of assessment. Assessment must satisfy the Principles of Assessment and Rules of Evidence and all regulatory requirements included within the Standards for Registered Training Organisations current at the time of assessment. Assessment must occur in suitable workplace operational situations where it is appropriate to do so; where this is not appropriate, assessment must occur in simulated suitable workplace operational situations that replicate workplace conditions. Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate. Resources for assessment must include access to: a range of relevant exercises, case studies and/or simulations relevant and appropriate materials, tools, facilities and equipment currently used in industry resources that current industry practices in relation to finding and rectifying faults in process final control elements and associated equipment applicable documentation, including workplace procedures, equipment specifications, regulations, codes of practice and operation manuals. |
