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 material and equipment conditions which may lead to outofspecification production

Knowledge and ability to implement organization procedures quality requirements at each production stage and relevant regulatory requirements within appropriate time constraints and work standards

Skills to identify and take appropriate action on the range of possible causes of product faults

Application of the knowledge of managing risks using the hierarchy of controls applied to the composite sheeting process 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 process and material problems including

characteristics of materials and behaviour in relation to heat pressure flow rate and time

function and operating principles of composite sheeting equipment machine components and ancillary equipment including the mechanical hydraulic pneumatic electrical and electronic principles which effect machine operation

impact of machine speed temperature pressure time during cycles on product quality and production output

phases of the composite sheet production cycle and the effect of the key variables on product quality in order to make appropriate adjustments to machine settings

processing behaviour of those polymers used for composite sheets

changes to materials at various stages of production

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

waste management and importance of nonconforming materials

polymer properties and their interactions with process conditions

relationships between polymer properties and process conditions

changes to polymer properties to better suit process requirements

product problems related to polymer properties

product problems related to process conditions

adjustments to process conditions to meet polymer and product requirements

Competence also includes the ability to

plan own work including predicting consequences and identifying improvements

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

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

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

identify when assistance is required to solve problems

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

Numeracy is required to the level of reading tables of figures and graphs and applying the resultant information using formula percentagesratios to determine the required mass of an additive eg catalyst pigment for a given amount of resin and similar manipulations and interpretation

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

Where the assessee does not currently possess evidence of competence in PMBPRODA Operate composite sheeting equipment it may be coassessed with this unit

Where the assessee does not currently possess evidence of competence in PMBPROD295A Operate composite sheeting 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 composite sheet process variables 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 intervention

all safety procedures are always followed

Assessment method and context

Assessment will occur on industrial composite sheeting equipment and will be undertaken in a worklike environment

Competence in this unit may be assessed

using an appropriate industrial composite sheeting machine requiring demonstration of startup 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 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 applies to the production of composite sheets (typically wall and roof sheeting) within the plastics and rubber industries. It includes the operation of all relevant additional equipment where that equipment is integral to the composites sheeting process.

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:

composite sheeting machine

components of composite sheeting machine such as profiling and compaction rollers, formers

additional equipment (eg curing equipment)

controller, such as PLC, if fitted

material loading equipment

hand tools, eg knives, cutters

relevant personal protective equipment.

Hazards

Typical hazards include:

spills

dusts/vapours

slip and fall

moving equipment

hazardous materials

manual handling hazards

variations in materials, colour, consistency or mix

equipment malfunction

variations in curing conditions

variations in materials and/or contamination of materials

variations in process conditions.

Variables

Key variables to be monitored include:

operating temperatures
