Unit of competency details

Unit descriptor 

This unit of competency covers the installation of mouldable refractory. It includes the use of tools and ancillary equipment and the mixing and application of appropriate mortars.

Application of the unit 

This unit of competency applies to operators who install and/or repair mouldable refractory materials. Moulded refractory may be the total requirements for the job, or it may need to join to brick/block or cast refractory.

This unit does NOT cover the installation of brick/block or cast refractory, refer to PMC552091B Prepare for , install and repair refractory brickwork /blockwork or PMC552093B Prepare for and cast refractory materials .

This competency also includes the mixing and application of refractory mortars as part of the installation.

This competency will typically be performed by a team of operators working under direction and to a specification and/or procedures.

EVIDENCE GUIDE 

The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment 

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.

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

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.

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.

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 unit of competency. Simulation should be based on the actual plant and will include 'walk-throughs' of the relevant competency components. A bank of scenarios/case studies/what ifs and questions will be required to probe the reasoning behind observable actions.

Method of assessment 

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

Guidance information for assessment 

Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed.

RANGE STATEMENT 

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. 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) may also be included.

Procedures 

All operations are performed in accordance with standard procedures and work instructions

Tools and equipment 

Tools and equipment include:

• moulding tools
• refractory mixing equipment
• lifting and placing equipment
• equipment allowing access

Installation 

Installation includes:

• moulding to shape
• correct thickness/cover
• conforming to required curves and angles while maintain cover
• tying mouldable to structure
• keying to existing refractory

Occupational health and safety  (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
