Application
Application of this unit
This competency is typically performed by advanced operators who are involved in the assembly of basic tyre components from intermediate production stages into a completed green tyre ready for curing. It also requires using a range of well developed skills requiring some discretion and judgement to recognised and resolve a range of problems.
The operator will:
check job sheets for work to be done
check setting and adjustments of equipment
start up and shut down equipment
monitor equipment operation
make appropriate adjustments to correct materials, equipment or process variations
solve routine production problems, seeking guidance where necessary or appropriate.

Required Skills
This describes the essential skills and knowledge and their level required for this unit.
Application of knowledge of the materials, equipment and process sufficient to recognise out of specification products, process problems and materials faults.
Knowledge of organization procedures, quality requirements at each stage of production and relevant regulatory requirements along with the ability to implement them within appropriate time constraints and work standards.
Application of the knowledge of managing risks using the hierarchy of controls applied to compound materials using and open mill blender. Application of approved hazard control and safety procedures and the use of PPE in relation to handling materials, equipment operation and cleanup.
Knowledge as a basis for solving processing and material problems including:
the function of the tyre building equipment and machine components
the terms radial force, inflation pressure, lateral force, internal force harmonics and concentricity
different components used in the building process, eg steel belts, treads
the function of different components, especially different tread compounds
range of products made using this method
reasons for differences in types and number of components used in different products
monitor equipment operation and product quality
material properties and their interactions with process conditions
relationships between material properties and process conditions
changes to material properties to better suit process requirements
product problems related to material properties
product problems related to process conditions
adjustments to process conditions to meet material and product requirements.
Competence also includes the ability to:
plan own work, including predicting consequences and identifying improvements
identify when the operator is able to rectify faults, when assistance is required and who is the appropriate source for assistance
identify and describe own role and role of others involved directly in the tyre building process
identify factors which may affect product quality or production output and appropriate remedies
pause or shut down equipment in abnormal circumstances
explain the effect of unauthorised or emergency shutdown in relation to safety and production requirements.
Language, literacy and numeracy requirements
This unit requires the ability to read and interpret typical product specifications, job sheets, procedures, material labels and safety information as provided to operators.
Writing is required to the level of completing workplace forms.
Basic numeracy is required, eg to determine that two 25 kg bags are needed to make up a requirement for 50 kg.
Evidence Required
The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, the range statement and the assessment guidelines for this training package.
Overview of assessment
A holistic approach should be taken to the assessment.
Assessors must be satisfied that the person can consistently perform the unit as a whole, as defined by the Elements, Performance Criteria and skills and knowledge.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
It is essential that competence is demonstrated in the knowledge and skills defined in this unit. These may include the ability to:
identify critical materials properties and process characteristics in relation to the process requirements and the end product
make adjustments to the process as required
identify and take appropriate action on problems and potential problems.
Consistent performance should be demonstrated. For example, look to see that:
the process runs consistently and smoothly, with the minimum need for human intervention
all safety procedures are followed.
Assessment method and context
Assessment will occur on an industrial machine(s) equipment and will be undertaken in a work-like environment.
Competence in this unit may be assessed:
by using an appropriate operating plant requiring demonstration of start-up, operation and shutdown procedures
in a situation allowing for the generation of evidence of the ability to recognise, anticipate and respond to problems
by using a suitable simulation and/or a range of case studies/scenarios
through a combination of these techniques.
In all cases it is expected that practical assessment will be combined with targeted questioning to assess the underpinning knowledge and theoretical assessment will be combined with appropriate practical/simulation or similar assessment. Assessors need to be aware of any cultural issues that may affect responses to questions.
Assessment processes and techniques must be culturally appropriate and appropriate to the oracy, language and literacy capacity of the assessee and the work being performed.
Specific resources for assessment
This section should be read in conjunction with the Range Statement for this unit of competency. Resources required include suitable access to an operating plant or equipment that allows for appropriate and realistic simulation. A bank of case studies/scenarios and questions will also be required to the extent that they form part of the assessment method. Questioning may take place either in the workplace, or in an adjacent, quiet facility such as an office or lunchroom. No other special resources are required.
Access must be provided to appropriate learning and/or assessment support when required. Where applicable, physical resources should include equipment modified for people with disabilities.
Range Statement
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Add any essential operating conditions that may be present with training and assessment depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts.
Where reference is made to industry codes of practice, and/or Australian/international standards, the latest version must be used.
