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 requirementsAll 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:emergency procedureswork instructionsstandard operating procedures (SOPs)safe work method statements (SWMS)formulae/recipesbatch sheetstemporary instructionsany similar instructions provided for the smooth running of the plant. |
Tools and equipment | Tools and equipment include:extruder equipment which may be single or twin screwancillary equipment that is integral to the process, including one or more of:water pumpfeedershopper loaderpelletiserdehumidifiers.Additional tools and equipment will be selected as required from:tools for taking sampleshand tools used in the processhoists/lifting equipment not requiring any special permits or licences manual handling aids, such as hand carts and trolleysrelevant personal protective equipment (PPE). |
Hazards | Hazards must be identified and controlled. Identifying hazards requires consideration of:weight, shape, volume of materials to be handledhazardous products and materialssharp edges, protrusions or obstructionsslippery surfaces, spills or leaksrotational equipment or vibrationhigh temperaturessmoke, dust, vapours or other atmospheric hazardselectricitygasgases and liquids under pressure structural hazardsequipment failuresmachinery, equipment and product massother hazards that might arise. |
Routine problems | Routine problems must be resolved by applying known solutions. Routine problems are predictable and include one or more of:variations in temperature and speedvariations in materials or contamination of materialsdie/tooling problems such as damage to diejob specifications which are not in accordance with usual practiceproduct problems, such as:dimension problemssurface appearancecolourdeformations.Known solutions are drawn from one or more of:procedurestrainingremembered experience.Non-routine problems must be reported according to according to relevant procedures. |
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 procedures, job specifications, basic machine control panels, material labels and safety data sheets (SDS)select and use tools and equipment to meet job specificationsmonitor extrusion and ancillary equipment using measured/indicated data and smell, sight, sound and feel as appropriate monitor and interpret key variables, including:differences between actual and set temperatures speeds, including screw speed and haul-offcolour and uniformitysurface finish and appearanceproduct finished thicknessoutput rateproduct integrity and general conformance to specification/sampleoperate and adjust the equipment to meet product quality and production output specificationspause the equipment or shut down equipment in normal and abnormal circumstancesidentify hazards and apply relevant hazard controlsapply safety procedures· apply housekeeping procedures· apply waste management proceduresrecognise early warning signs of equipment/processes needing attention or with potential problemsrecognise routine and non-routine problemsidentify when the operator is able to rectify faults, when assistance is required and who is the appropriate source for assistancetake action to resolve faults or report faults to appropriate personneldistinguish between possible causes of routine faults, including:raw material variations/contaminationprocess abnormalitiesprocedural errors mechanical abnormalitiescommunicate effectively with team/work group and supervisorscomplete workplace recordsdo basic arithmetical manipulations, including additions, subtractions, divisions, fractions and percentages.
