impact of changes and adjustments to the winding gear on film properties

nature of mechanical hydraulic pneumatic electrical and electronic principles which effect machine operation and product development

safety procedures and the use of PPE in relation to handling materials equipment operation and cleanup

the hierarchy of control including engineering controls

impact of variations in raw materials and equipment operation in relation to final product

changes to materials at various stages of production

waste management and importance of nonconforming materials

plan own work including predicting consequences and identifying improvements

interpret from production requests the correct selection and use of equipment materials processes and procedures

maintain output and product quality using appropriate instruments controls test information and readings

make adjustments to equipment operation to rectify variations in equipment operation or product quality

check blown film line for correct setup to job specifications and implement adjustments or report deviations immediately

start up equipment and make appropriate adjustments to bring process on line

make measurements when required and identify product out of specification

safely shut down equipment in normal or abnormal circumstances

identify and describe own role and role of others involved directly in the film process

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

identify when the operator is able to rectify faults and when assistance is required

identify hazards of the materials and process

implement appropriate procedures for hazard control

use PPE safely handle products and materials read relevant safety information and apply safety precautions appropriate to the task

distinguish between causes of faults such as materials contaminants equipment adjustmentssetup equipment maintenance requirements

Language literacy and numeracy requirements

This unit requires the ability to read and interpret typical product specifications job sheets and material labels as provided to operators

Writing is required to the level of completing workplace forms and production reports

Basic numeracy is required eg to determine how many kg kg and kg bags are needed to make up a requirement for kg

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

Overviewof assessment

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

Where the assessee does not currently possess evidence of competency in PMBPRODA Operate blown film equipment it may be coassessed with this unit

Where the assessee does not currently possess evidence of competency in PMBPROD216A Operate blown film equipment, it may be co-assessed with this unit.

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 blown film process characteristics in relation to the process requirements and the end product

Consistent performance should be demonstrated For example look to see that

production quality and output standards are met consistently

the process runs consistently and smoothly

Assessment method and context

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

Competence in this unit may be assessed

by using an appropriate industrial blown film equipment

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
