Elements and Performance Criteria

1. Establish the suitability of resources
   • Check all information conforms with resources
   • Record discrepancies in information
   • Report any inaccuracies in information to the person in charge
   • Identify and select materials, components, tools and equipment
2. Undertake mechanical design
   • Determine strength requirements
   • Determine operating temperature range
   • Select materials/mix with appropriate mechanical strength
   • Identify hazards of materials and processes to be used and apply hierarchy of control to control hazards
   • Determine expansion which will occur for this material
   • Adjust material/mix to be suitable for temperatures
3. Undertake thermal design
   • Determine heat flow through the refractory
   • Determine interface temperatures for multi-component linings
   • Use simple software
   • Determine interface bonding/anchor issues
4. Specify refractory design
   • Specify materials to be used
   • Specify installation method to be used
   • Confirm specification meets customer needs and installer requirements

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: health, safety and environmental (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.
Procedures	All operations must be performed in accordance with relevant procedures. Procedures are written, verbal, visual, computer-based or in some other form, and include one or any combination of: manufacturer's technical information job cards drawings emergency procedures work instructions standard operating procedures (SOPs) safe work method statements (SWMS) formulas/recipes batch sheets temporary instructions any similar instructions provided for the smooth running of the plant.
Hazards	Hazards must be identified and controlled. Identifying hazards requires consideration of: health and safety risks sustainability risks regulatory risks.
