   • Maintain supply of material(s) as required.
   • Complete logs and records when as required.
   • Collect and segregate scrap, trim and other materials as required in accordance with procedures.
   • Keep equipment and work area clean area in accordance with procedures.
   • Pause machine cycle and perform emergency stop, as required by procedures.
4. Respond to routine problems in accordance with procedures.
   • Recognise known faults that occur during the operation.
   • Identify and take action on causes of routine faults.
   • Log problems as required.
   • Identify non-routine process and quality problems and take appropriate action.

Required Skills

This describes the essential skills and knowledge and their level required for this unit

Application of an operational knowledge of the materials equipment and process sufficient to recognise out of specification products process problems and materials faults For example temperature measurements are essential for curing of tyres where the temperature must be kept constant during the process Monitoring the temperature inside the mould is too difficult therefore the temperature of the condensate is monitored using specialised equipment

Knowledge of organization procedures 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 the tyre curing process Application of approved hazard control and safety procedures and the use of PPE in relation to handling materials equipment operation and cleanup

Knowledge of and skills in the operation of tyre curing equipment and main components sufficient for consistent production of quality products including

production workflow sequences and materials demand

the reasons for checking process control panels and reporting readings which are outside of normal range of process variability

accurately monitoring equipment operation and product quality

the potential effects of variations in raw materials and equipment operation in relation to quality of product

processing behaviour of polymers and the role of additives

waste management and knowing the importance of reusing nonconforming products wherever possible

correct selection and use of equipment materials processes and procedures

explain the effect of unauthorised or emergency shutdown in relation to safety and production requirements

identify factors which may affect product quality or production output and appropriate remedies

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 curing process

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 kg bags are needed to make up a requirement for 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

apply the required skills and knowledge to operate a tyre curing machine

apply approved procedures

Consistent performance should be demonstrated For example look to see that

tyre curing production standards are met consistently

all safety procedures are followed

Assessment method and context

Assessment will occur on an industrial curing machines equipment and will be undertaken in a worklike environment

Competence in this unit may be assessed

by using an appropriate industrial tyre curing machine requiring demonstration of operation and emergency stop procedures

in a situation allowing for the generation of evidence of the ability to respond to problems

by using a suitable simulation andor a range of case studiesscenarios

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 practicalsimulation 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 studiesscenarios 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 andor 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.

Context

This competency unit includes curing operations.

This competency applies to all work environments within the tyre manufacture sector. It also includes the operation of all relevant ancillary equipment.

Procedures

All operations are performed in accordance with procedures.

Procedures include all relevant workplace procedures, work instructions, temporary instructions and relevant industry and government codes and standards.

Tools and equipment

This competency includes use of equipment and tools such as:

curing press (eg bagomatic, collapsible bladder or shear strip, solid bladder

ancillary equipment (eg screens/strainers, computer data systems, ball float steam traps, condensate temperature and steam trap monitoring system)

curing agents (eg sulphur sources, peroxides, metal oxides, amines, and phenolic resins)

relevant personal protective equipment.

Hazards

Typical hazards include:

manual handling

noise

humidity

temperatures (eg from air and steam)

fumes/vapours (eg from curing agents)

cleaning equipment (eg screens/strainers)

stationary and moving machinery.

Problems

'Respond to routine problems' means 'apply known solutions to a limited range of predictable problems'. Typical process problems may include:

poorly aligned guides

mould incorrectly placed on machine

poor mould closure/alignment

poorly prepared mould (dirty/mould release)

incorrect temperature settings

mould temperature/steam pressure/air blinded/waterlogged

mould/air pressure.

Typical product problems may include:

contaminated green tyres

squashed or distorted green tyres

scorched rubber

curing time/cycle

product

excessive trim/spue

out of round/eccentric.
