Version 1.0
Issue Date: March 2024
Application of this unit
This competency applies to operators who are required to undertake the routine operation of rotational moulding equipment. The key factors are the making of products to meet quality standards and workplace requirements. This competency is typically performed by operators working either independently or as part of a work team.
It includes:
checking job sheets for work requirements
following approved hazard minimisation procedures for any hazards connected with materials and process, using work instructions, labels and materials safety data sheets, and in accordance with OHS legislative responsibilities
monitoring rotational moulding equipment operation and reporting process variations
checking product for quality and conformity to specifications discarding non-conforming products ensuring discarded materials are reused where possible and waste and scrap is disposed of in accordance with workplace instructions
identifying and taking action on routine process problems
completing logs and reports.
This competency covers the operation of equipment, including both rotating and 'rock and roll' modes, and the resolving of routine problems to procedure. It does not cover open flame equipment. (see PMBPROD284B - Operate open flame moulding equipment)
You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Evidence Required
List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
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:
recognise the importance of material properties and qualities
apply approved procedures
take appropriate action to resolve faults or report faults to appropriate personnel
explain and implement emergency shutdown procedures.
Consistent performance should be demonstrated. For example, look to see that:
rotational moulding production standards are met consistently
upstream and downstream communication is timely
effective operating procedures and work instructions are read and interpreted correctly
problems are identified and appropriate action is taken (ie the problem is fixed or reported)
all safety procedures are followed.
Assessment method and context
Assessment will occur on industrial rotational moulding equipment 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 situation allowing for the generation of evidence of the ability to 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.

Assessment Tasks
Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.
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 out of specification products, process problems and materials faults.
Knowledge of organisation procedures and relevant regulatory requirements along with the ability to implement them within appropriate time constraints and work standards.
Knowledge of and skills in the operation of rotational moulding equipment and main components sufficient for consistent production of quality products including:
operation of rotational moulding equipment and components
effects of shrinkage on material colour
production workflow sequences and materials demand
reasons for checking process control panels and reporting readings which do not conform to the work instructions
approved hazard control and safety procedures and the use of PPE in relation to handling materials
equipment operation and cleanup
potential effects of variations in raw materials and equipment operation in relation to quality of product
waste management and importance of reusing non-conforming products wherever possible
correct selection and use of equipment, materials, processes and procedures
plan own work, including predicting consequences and identifying improvements
monitor equipment operation and product quality
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 rotational moulding process
identify factors which may affect product quality or production output and appropriate remedies
use PPE, safely handle products and materials, read relevant safety information and apply safety precautions appropriate to the task
pause equipment, or shut down equipment in abnormal circumstances
explain the effect of unauthorised or emergency shutdown in relation to safety and production requirements
distinguish between possible causes of routine rotational moulding faults such as: incorrect quantity of materials; contaminated materials/additives; equipment faults; mould damage; temperature/time faults; rotation speed/motion problems; wrong raw materials/additives; incorrect quantity of materials/additives; machine failure.
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 25 kg bags are needed to make up a requirement for 50 kg.
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.
