Elements and Performance Criteria

This competency unit includes of equipment such as:
protective clothing, hearing protection, safety glasses, adequate ventilation
hand and power tools
mobile plant
refractory support mechanisms.

This competency unit may vary according to:
length and type of kiln
the type of process, ie, dry, wet, semi-wet, semi-dry
type of kiln maintenance being performed
method of waste disposal.

Typical problems include:
furnace/ kiln problems
major refractory problems.
All work is performed in accordance with standard procedures and work instructions.

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.

Essential knowledge and enterprise requirements
Knowledge and understanding of the process sufficient to recognise variance from specification and then analyse the problem to determine the level of appropriate action required, which is consistent with operating guidelines.
Knowledge of the enterprise's standard procedures and work instructions and relevant regulatory requirements, along with the ability to implement them within appropriate time constraints and in a manner relevant to the operation of the process.

Competence includes the ability to:


apply and/or explain:

safe work practices
function of tools/equipment used
procedures used to prepare the kiln
procedures used to install refractory
first-line maintenance procedures required

distinguish between causes of faults such as:

refractory materials
refractory problems
as is relevant to the practical operation of the process.

Critical aspects
It is essential that the process be understood and that the importance of critical material properties is known. Competence must be demonstrated in the ability to recognise and analyse potential situations requiring action and then in implementing appropriate corrective action.

Consistent performance should be demonstrated. In particular look to see that:

replacement follows standard procedures
correct materials are used
permit and other health and safety procedures are followed.
Competence must be demonstrated in the operation of all ancillary equipment to the level required for this competency unit.

Assessment method and context
Competence in this unit may be assessed by observation over time on an operating plant. Where this is done, the timeframe must allow for adequate assessment of operation under all normal and a range of abnormal conditions. Where this is not practical, additional assessment techniques must be used.
Competence may also be assessed by use of a suitable simulation and/or a range of case studies/scenarios. A combination of these techniques should be used to ensure the competency is adequately assessed.
In all cases it is expected that the practical assessment will be supported by targeted questioning to assess the underpinning knowledge. Questioning will be undertaken in such a manner as is appropriate to the language and literacy levels of the operator and reflecting the requirements of the competency.

Resource implications
Resources required include suitable access to an operating plant or equipment which allows for appropriate and realistic simulation. A bank of case studies/scenarios will also be required where these form part of the assessment method. Questioning may take place either in the workplace, or in an adjacent, quiet facility such as an office or lunch room. No other special resources are required.
