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, manual handling 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 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)formulas/recipesbatch sheetstemporary instructionsany similar instructions provided for the smooth running of the plant. |
Tools and equipment | Tools and equipment include:calenders ancillary equipment that is integral to the process.Additional tools and equipment will be selected as required from:basic hand toolsmill knivesthickness gaugesprofiling gauges/tools/jigsnip adjusting barsstrainers metal detectorhoists/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:restricted spacesweight, shape, volume of materials to be handledhazardous products and materialsknives, blades and cutting toolsrotational equipment or vibrationsharp edges, protrusions or obstructionsslippery surfaces, spills or leakssmoke, dust, vapours or other atmospheric hazardshigh temperatureselectricitygasgases and liquids under pressure structural hazardsequipment failuresmachinery, equipment and product massother hazards that might arise. |
Problems | Routine and non-routine problems must be resolved.Non-routine problems must be resolved by applying operational knowledge to develop new solutions, either individually or in collaboration with relevant experts, to:determine problems needing actiondetermine possible fault causesdevelop solutions to problems which do not have a known solutionfollow through items initiated until final resolution has occurredreport problems outside area of responsibility to designated person.Non-routine problems are unexpected problems or variations of previous problems and include one or more of:unstable process variables sub-optimal operation variations in feed ratesvariations in qualityemergency situations.Operational knowledge includes one or more of:procedurestrainingtechnical information, such as journals and engineering specificationsremembered experiencerelevant knowledge obtained from appropriate people.Routine problems are predictable and have known solutions and include one or more of:incorrect machine set-up, especially the nip setting tensionstemperature problems processing problems equipment malfunctions uniformity of productmaterials problems (e.g. raw material contamination, incorrect quantity of materials). |
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:

Knowledge Evidence
Must provide evidence that demonstrates knowledge relevant to their job sufficient to operate independently and to solve routine and non-routine problems, including knowledge of:
products, materials and material characteristics behaviour of materials in relation to key process variables quality requirements at each production stage function and operating principles of calendering equipment, machine components and ancillary equipmentmechanical , hydraulic, pneumatic, electrical and electronic principles which affect machine operationcalendering processesbehaviour of materials in relation to heat, pressure, flow rate, tension and timeimpact of machine operating parameters on product quality and production output factors which may affect product quality or production output and appropriate remediespolymer properties and their interactions with process conditionsimpact of variations in raw materials and equipment operation in relation to final product routine and non-routine problems that may arise, the range of possible causes and appropriate actionsorganisation procedures relevant to the work environment/job rolehierarchy of controlhazards that may arise in the job/work environment and:their possible causes potential consequencesappropriate risk controls.
