Unit Descriptor

Unit descriptor 

This competency applies to plant technicians who operate equipment to spray aluminium on carbon anodes used in the aluminium smelting process.

Application of the Unit

Application of the unit 

This competency unit typically covers items of equipment, such as:

  • carbon anode aluminium spray station
  • molten aluminium delivery
  • conveyors, power and free
  • aluminium melting furnace (may require MEM04001B Operate melting furnaces )
  • cranes (may require PMASUP237B Undertake crane , dogging and load transfer operations )

The plant technician would:

  • operate the aluminium spray station
  • operate molten aluminium delivery system
  • recognise and respond to 'out-of-parameter' issues
  • respond to emergency situations
  • identify and control hazards in the workplace.

Generally the operator would be part of a team during start up and shut down procedures and would be expected to be capable of demonstrating competence in all parts of this unit. At all times they would be liaising and cooperating with other members of the team.

This unit does not require the operation of a central control panel

Evidence Guide

EVIDENCE GUIDE 

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 for this unit of competency will be on an operating plant. 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 timely assessment of parts of this competency unit (eg Elements 2, 5). 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.

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:

  • emergency responses are known.
  • hazards are recognised and all site requirements to reduce or remove hazards are known and completed as part of the job.
  • early warning signs of equipment/processes needing attention or with potential problems are recognised, that is, monitoring systems in the carbon anode spraying process including equipment, material handling systems and mobile equipment.

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 that 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 other relevant units.

This competency may be assessed in conjunction with:

  • MSAPMOHS200A Work safely 
  • MSAPMOHS110A Follow emergency response procedures 
  • PMASUP237A Undertake crane , dogging and load transfer operations 
  • TDTD1097B Operate a forklift 
  • MSAPMSUP205A Transfer loads 

Other units which are relevant to the job.

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.
