Application of this unit
This competency applies to advanced operators who splice multiple ply textile reinforced conveyor belts (fabric ply belts). The key factors are the ability to safely access the belt, complete the splice and put safely back into service. This competency is typically performed by advanced operators working either independently or as part of a work team.
The operator will:
plan the splicing job
select and arrange all equipment and materials
prepare the belt for splicing
splice the belt and cure the join on site
inspect the splice and either approve the work or re-do the splice
identify any hazards and take appropriate action
clean up site, dispose of scrap and recycle materials where possible
complete logs and reports.
This competency unit does not cover splicing of steel cord belts (refer to PMAPROD374B ) or solid woven conveyor belts (refer to PMBPROD377A ).
Note that this competency unit covers splicing carried out in a workshop or other off-site facility. If the work involves on site work, then this competency should be considered in conjunction with MSAOPS363A Organise on site work.
Prerequisites
This unit of competency has the prerequisite of PMBPROD265B Operate portable vulcanising equipment.

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. For example, consumables for use in the splicing operation must be checked for compatibility with the belt and that materials are within recommended shelf life.
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 fabric ply belt splicing. 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 and/or explain:
impact of incorrect or faulty joining processes
production workflow sequences and inherent hazards with conveyors
stresses and tensions on working belts and the common failure causes
correct selection and use of equipment, materials, processes and procedures
size, shape and orientation of steps to form the overlap multi ply splice
resultant tensile strength of spliced fabric belt
products, materials and material characteristics for the splice and cover
effects of temperature and time on the curing process
changes in conveyor and joining materials during the joining process.
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 conveyor belt and system specifications, job sheets and material labels as provided to operators.
Writing is required to the level of completing workplace forms and job reports.
Numeracy is also required, eg to ensure accuracy of measurements and integrity of the splice.
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 PMBPROD265B Operate portable vulcanising equipment, it may be co-assessed with this unit.
This unit may also be co-assessed with 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 an industrial belt and will be undertaken in a work-like 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 workshop or conveyor manufacturing facility
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.
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.
