Elements and Performance Criteria

This unit covers the installation of refractory brickwork. It includes the use of tools and ancillary equipment and the mixing and application of appropriate mortars.
Brickwork/blockwork may be the total requirements for the job, or it may need to join to moulded or cast refractory.

OHS
All operations are subject to stringent OHS requirements and these must not be compromised at any time. Where there is an apparent conflict between performance criteria and OHS requirements, the OHS requirements take precedence.

Assessment context and methods
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 or case studies/scenarios may be required to allow for timely assessment of parts of this competency 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.

Critical aspects

Competence must be demonstrated in the ability to recognise situations requiring action and then in implementing appropriate corrective action. Consistent performance should be demonstrated. In particular look to see that:

signs of problems or potential problems with the equipment/processes are recognised
appropriate action is taken in a timely manner
hazards are recognised and appropriate action is taken to control risks arising from such hazards.
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. The assessment activities should include responding to a range of problems.

Resource implications
Assessment will require access to appropriate equipment over a 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.

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

It may be appropriate to assess this unit concurrently with:

PMAOHS100B Follow OHS procedures.
