Elements and Performance Criteria
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 materialsAustralian/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 riskssustainability risksregulatory risksbusiness risks. |
Performance Evidence
Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria and demonstrate the ability to:
analyse and interpret technical reports, technical specifications and data confirm requirements for refractory end use conditions, including:surface temperature of refractoryrequired temperature gradient through refractory/outside surface temperaturechemical condition (e.g. pH)mechanical condition (e.g. impingement)temperature or other cyclingcommunicate technical information verbally and in writing/drawings communicate with internal and external stakeholders, including one or more of:customer representativestechnical expertsregulatorsmanagementrefractory material selector refractory installerdetermine optimum refractory installation by evaluating criteria, including:alignment to technical requirements of the end usepreliminary design calculationsinstallation, repair or removal issues cost (material, installation, repair, life cycle)health, safety and environmental (HSE) risks (installation, use, repair, removal and disposal)relative benefits/costs/risks of block/precast, monolithic/castable, gunite/shotcrete, refractory coating and multilayer (e.g. hard face over insulating refractory) refractory linings negotiate with relevant stakeholders and document agreed requirements and design and technical specifications apply complex and/or theoretical mathematical calculationssolve complex problems to determine design and specification which best deliver the technical requirement at the lowest cost and the least HSE risk develop technical drawings manually or with computer-aided drafting (CAD).
Knowledge Evidence
Must provide evidence that demonstrates knowledge relevant to their job sufficient to fulfil their job role, including knowledge of:
properties of all common refractory materialstypical limitations and applications of all common refractory systemsinstallation methods and their advantages, disadvantages, typical uses and limitationsheat transfer calculations (resistances in series and parallel)structural calculations (beam, column, arch, strength of refractory materials, and physical properties of refractory materials)thermal expansion (calculation of and allowance for)refractory anchors, types, uses and selection refractory installation methods and their impact on designcommon refractory repairs and their impacts on designmethods of reuse, recycling and disposal of refractories at the end of their life and the differences for different types of refractory systemscritical refractory specificationsregulatory frameworkhierarchy of controlhazards that may arise in the job/work environment and:their possible causes potential consequencesappropriate risk controls.
