The Evidence Guide provides advice on assessment and must be read in conjunction with the Performance Criteria, Required Skills and Knowledge, the Range Statement and the Assessment Guidelines for the Training Package.

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 walk-throughs of the relevant competency components. Simulations may also include the use of case studies/scenarios and role plays.

This unit of competency requires a significant body of knowledge which will be assessed through questioning and the use of what-if 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 equipment/processes 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.

Also confirm that the person undertaking this competency has the ability to:

implement all OHS and environmental procedures relevant to this unit

apply the permit to work system within the context of this unit

interpret a range of process and control system drawings and schematics in order to undertake required or identified repairs/modifications to electrical systems.

These aspects may be best assessed using a range of scenarios/case studies/what-ifs as the stimulus with a walk-through 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 scenarios/case studies/what-ifs 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. Consider co-assessment with relevant OPS units.

In a major hazard facility, it may be appropriate to assess this unit concurrently with relevant OHS 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.

This describes the essential skills and knowledge and their level, required for this unit.

Required skills

A person undertaking this unit of competency would also be expected to demonstrate the knowledge and ability to:

test, repair, recommission and monitor the operational condition of instrument control systems utilised within the industry

communicate and report the operational condition and history of instrument control systems to other team members and company personnel

coordinate own work and the work of others including on site contractors/operators.

It is essential that a person be able to apply the underlying skills and knowledge contained within this competency across a range of instrument and control systems.

Required knowledge

A demonstrated working knowledge and application of the company-specific work organisations and workflow.

Demonstrated knowledge and application of:

process and plant schematic and instrumentation diagrams

operations and functions of instrumentation and control devices

control functions, control regimes, adjustments and tuning

test and calibration methods

test equipment typically used with control system repair/maintenance/calibration.

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. Add any 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.

Codes of practice/ standards

Where reference is made to industry codes of practice, and/or Australian/international standards, the latest version must be used.

Context

Control systems for one or more of the following may be included:

compressor systems and equipment (compressors, monitoring systems, power supply systems, pumps, pumping systems and equipment, pressure vessels/filtration equipment, coolers, scrubbers, expanders, anti surge systems, safety systems and compressor control systems)

prime movers which may include turbine engines, reciprocating engines, electric motors (fuel and carburettion systems, ignition systems, lubrication systems, induction and exhaust systems, governing systems, power supply systems, safety and shutdown systems)

flow systems (piping systems, metering equipment, flow control equipment, pressure and temperature transmitters and transducers, telemetry equipment, PLCs, flow computers, electro-pneumatic process control equipment and their associated on-line analytical instrumentation such as gas chromatographs, moisture analysers, gas sampling and gas analysis equipment, pig)

valve systems (non-control valves, control and shut off valves, non-return or check valves and pressure relief valves, manual hand operated actuator, gas/hydraulic actuator and pneumatic valves).

Emergency responses

Emergency responses include:

leaks/loss of containment

fire

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 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.

Persons are required to have skills in hazard identification, assessment and application of control measures.
