Elements and Performance Criteria

1. Confirm required end use
   • Liaise with relevant stakeholders
   • Confirm the end use conditions for the refractory
   • Identify discrepancies or conflicts in requirements
   • Negotiate a consistent set of requirements for the refractory material
2. Short list appropriate refractory materials
   • Compare the properties of refractory materials with the set of requirements
   • Identify situations where the use of more than one material may be desirable
   • Rank possible materials solutions
   • Identify health, safety and environment (HSE) risks of top ranked possible material solutions
   • Estimate the cost of top ranked possible material solutions
3. Recommend a refractory material/combination of refractory materials
   • Liaise with relevant stakeholders
   • Determine installation, repair or removal issues of relevance to the material selection
   • Review shortlist ranking
   • Recommend optimum material/combination of materials for the end use
4. Develop technical specification for recommended materials
   • Determine suitable format for specification
   • Prepare specification
   • Review specification with refractory designers and installer
   • Modify specification if required
   • Publish specification in required format to required people/organisations

Range Statement

This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.
Regulatory framework	The latest version of all legislation, regulations, industry codes of practice and Australian/international standards, or the version specified by the local regulatory authority, must be used. Applicable legislation, regulations, standards and codes of practice include: HSE legislation, regulations and codes of practice relevant to the workplace, equipment and production processes and hazardous materials Australian/international standards relevant to the materials being used and products being made any relevant licence and certification requirements. All operations to which this unit applies are subject to stringent HSE requirements, which may be imposed through state/territory or federal legislation, and these must not be compromised at any time. Where there is an apparent conflict between performance criteria and such requirements the legislative requirements take precedence.
HSE and other risks	Identification of HSE and other risks includes consideration of: health and safety risks sustainability risks regulatory risks business risks.

temperature or other cycling

communicate technical information verbally and in writing

communicate with internal and external stakeholders, including one or more of:

customer representatives

technical experts

regulators

management

refractory designer

refractory installer

determine optimum refractory material/s by evaluating criteria, including:

alignment to technical requirements of the end use

installation, repair or removal issues

cost throughout the life cycle

health, safety and environmental (HSE) risks throughout the life cycle

relative benefits/costs/risks of single refractory material, mixing multiple refractory materials, use of refractory materials in series, and use of refractory materials in parallel

negotiate with relevant stakeholders and document agreed requirements and technical specifications

apply complex and/or theoretical mathematical calculations

solve complex problems to determine material/s technical specification which best delivers the technical requirement at the lowest cost and the least HSE risk.
