Elements and Performance Criteria

This unit covers all common types of refractory failures. The failure needs to be recognised and distinguished from other possible causes. Possible causes for the failure also need to be identified, particularly if failure is unexpected/refractory life is shorter than expected.
Investigation involved the collection of evidence, and may require the specifying of appropriate tests and the analysis of plant records and logs.
The report should summarise the nature of the failure, the cause(s), the methods used to determine this cause and the conclusions drawn and recommendations made.

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 appropriate exercises. 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, materials and applications.
Simulation or case studies/scenarios may be required to allow for timely assessment of parts of this competency unit. Simulation should be based on situations as close to real as possible, and will include 'walk-throughs' of the relevant competency components. Simulations may also include the use of case studies/scenarios and role plays.

Resource implications
Assessment will require access to several examples of refractory failures for some 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
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.
Where the analysis of refractory failure is to occur on site, or in a vessel then competency in the appropriate OHS and/or permit units is also required.
