   • Inform customer when belt is ready for use, or prepare belt for storage or delivery.
4. Clean work area.
   • Clean, inspect and store tools and equipment used.
   • Tag unserviceable tools and equipment, identify faults and inform relevant personnel.
   • Clean work area and return to approved condition.
   • Dispose of waste or recycle according to procedures.
   • Complete appropriate workplace documentation.
5. Anticipate and solve problems
   • Recognise a problem or a potential problem.
   • Determine problems needing priority action.
   • Refer problems outside area of responsibility to appropriate person, with possible causes.
   • Seek information and assistance as required to solve problems.
   • Solve problems within area of responsibility.
   • Follow through items initiated until final resolution has occurred.

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 out of specification production

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 belt repairs Application of approved hazard control safety procedures and the use of PPE in relation to handling materials equipment operation and cleanup

Competence includes the ability for the practical completion of the job to apply andor explain

impact of incorrect or faulty repair processes or materials

production workflow sequences and inherent hazards with conveyors

distinguish between causes of conveyor belt faults eg abrasion impact tearing or other damage mechanical problems materials failure

stresses and tensions on working belts and the common failure causes

correct selection and use of equipment materials processes and procedures

products materials and material characteristics

effects of temperature pressure and time on the curing process

changes in conveyor and repair materials during the repair process

requirements for cable lay up and ply replacement in forming a satisfactory repair as applicable

Competence also includes the ability to

plan own work including predicting consequences and identifying improvements

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

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

Numeracy is also required eg to determine the angle and dimensions of the repair

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 competency in the following units of competency they may be coassessed with this unit

PMBPRODB Operate portable vulcanising equipment

PMBPROD265B Operate portable vulcanising equipment

PMBPRODB Repair conveyor belt covers

PMBPROD369B Repair conveyor belt covers

MSAOPSA Organise on site work

MSAOPS363A Organise on site work

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 conveyor operating characteristics in relation to the condition of the belt

plan own work process within organisational procedures and explain the reasons for the steps in the process

take appropriate action to observe equipment materials and products for out of specification results make repairs and identify problems to be reported

Consistent performance should be demonstrated For example look to see that

production quality and output standards are met consistently

problems are anticipated from process observations

problems are efficiently resolved

the repair runs consistently and smoothly

Assessment method and context

Assessment will occur on a industrial belts and will be undertaken in a worklike environment

Competence in this unit may be assessed

on a processing plant allowing for operation under all normal and a range of abnormal conditions

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 belt carcass repair activities in either on-site or repair facility circumstances. It includes the operation of all relevant additional equipment where that equipment is integral to the conveyor belt carcass repair 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:

knives and cutting tools

hoists/lifting equipment not requiring any special permits or licences

hand tools (eg pliers, brushes)

vulcanising equipment

relevant personal protective equipment

belt restraining devices

portable power generating equipment.

Hazards

Typical hazards include:

damaged rubber and cords

dusts/vapours

manual handling hazards

cutting hazards

working on belts in-situ (where appropriate)

heat and pressure.

Problems

'Anticipate and solve problems' means resolve a wide range of routine and non-routine problems, using product and process knowledge to develop solutions to problems which do not have a known solution/a solution recorded in the procedures.

Typical process and product problems may include:

difficulties arising from the location

contamination of materials

communication problems (on-site)

tool problems

variations in materials and/or contamination of materials

vulcanising problems.

Variables

Key variables to be monitored include:

belt condition

belt location

degree of damage

forces acting on the conveyor

belt environmental conditions

lock-out of equipment.
