Overview of assessment

Assessment of this unit should include demonstrated competence on actual plant and equipment 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

Simulation may be required to allow for assessment of parts of this unit Simulation should be based on the actual plant and will include walkthroughs of the relevant competency components Simulations may also include the use of case studiesscenarios role plays and D virtual reality interactive systems In the case of evacuation training or training for competencies practised in life threatening situations simulation may be used for the bulk of the training

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 This can be assessed through questioning and the use of whatif scenarios both on the plant during demonstration of normal operations and walk throughs of abnormal operations and off the plant

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 equipmentprocesses needing attention or with 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 return to full performance

obvious problems in related plant areas are recognised and an appropriate contribution made to their solution

These aspects may be best assessed using a range of scenarioscase studieswhatifs as the stimulus with a walkthrough forming part of the response These assessment activities should include a range of problems including new unusual and improbable situations which may have been generated from the past incident history of the plant incidents on similar plants around the world hazard analysis activities and similar sources

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 A bank of scenarioscase studieswhatifs will be required as will a bank of questions which will be used to probe the reasoning behind the observable actions

Method of assessment

In all plants it may be appropriate to assess this unit concurrently with relevant teamwork and communication units

Guidance information for assessment

Assessment processes and techniques must be culturally appropriate and appropriate to the oracy language and literacy capacity of the assessee and the work being performed
