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:health, safety and environmental (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. |
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 cardsdrawingsemergency procedureswork instructionsstandard operating procedures (SOPs)safe work method statements (SWMS)formulas/recipesbatch sheetstemporary instructionsany similar instructions provided for the smooth running of the plant. |
Problems | Routine problems must be resolved by applying known solutions. Routine problems are predictable and include one or more of:damaged/worn tools/equipmentincorrect tools/equipment for jobincorrect/incomplete information for jobvariations in materialspreparation problems.Known solutions are drawn from one or more of:procedurestrainingremembered experience.Non-routine problems must be reported according to according to relevant procedures. |
Tools and equipment | Tools and equipment include:mixing equipmentair compressorswater addition equipmentgunning equipment/nozzlesequipment allowing access. |
Hazards | Hazards must be identified and controlled. Identifying hazards requires consideration of:heat, smoke, dust, vapours or other atmospheric hazardsweight, shape, volume of materials to be handledhazardous products and materialssharp edges, protrusions or obstructionsslippery surfaces, spills or leakselectricitygasgases and liquids under pressure noiserotational equipment or vibrationplant services (steam, condensate, cooling water, etc)structural hazardsequipment failuresmachinery, equipment and product masslimited head spaces or overhangs working at heightsworking in restricted or confined spacesother hazards that might arise. |
Records and reports | Records include one or more of:log books/sheetselectronic recordsjob/work sheetsother records used for the smooth running of the plant.Reports include one or more of:paper or electronic-based logs and reportsverbal/radio reportsreporting items found which require action. |
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:
read and interpret manufacturer's technical information, job sheets, procedures, material labels and safety information confirm information/procedures are available and conform with resources identify and select materials, components, tools and equipmentuse and maintain tools and equipmentmix and apply shotcrete to achieve required specifications monitor key variables, including:uniformity and thickness of courseconsistency of mixcorrect compactionconforming to required curves and anglesadhesion to surfacetying to structurekeying to existing refractory cutting requirementssupport requirementsmonitor installation integrity and conformance to specification and make adjustments to meet specificationsrecognise routine and non-routine problemsidentify when the operator is able to rectify problems, when assistance is required and who is the appropriate source for assistancetake action to resolve problems or report them to appropriate personneldistinguish between possible causes of routine problems, including:raw material variationsequipment faults/abnormalitiesprocess/procedure errorsidentify hazards and apply relevant hazard controlsapply safety procedurescommunicate effectively with team/work group and supervisorscomplete workplace recordsdo basic arithmetical manipulations, including additions, subtractions, divisions, fractions and percentages.
Knowledge Evidence
Must provide evidence that demonstrates knowledge relevant to their job sufficient to operate under routine only supervision and to solve routine problems, including knowledge of:
