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:
injection blow moulding production standards are met consistently upstream and downstream communication is timely and 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 blow moulding equipment in a work-like environment.
Competence in this unit may be assessed:
by using an appropriate, industrial injection blow moulding machine requiring demonstration of operation and emergency stop procedures
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.
Submission Requirements

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 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 the injection blow moulding process. Application of approved hazard control, safety procedures and the use of PPE in relation to handling materials, equipment operation and cleanup.
Knowledge of and skills in the operation of injection blow moulding equipment and main components sufficient for consistent production of quality products including:
production workflow sequences and materials demand
the reasons for checking process control panels and reporting readings which are outside of normal range of process variability
accurately monitoring equipment operation and product quality
the potential effects of variations in raw materials and equipment operation in relation to quality of product
processing behaviour of polymers and the role of additives
waste management and knowing the importance of reusing non-conforming products wherever possible
correct selection and use of equipment, materials, processes and procedures
explain the effect of unauthorised or emergency shutdown in relation to safety and production requirements
identify factors which may affect product quality or production output and appropriate remedies.
Competence also includes the ability to:
plan own work, including predicting consequences and identifying improvements
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 injection moulding process.
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 for 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.
Context
This competency applies to all injection blow moulding operations within the plastics and rubber sectors. It includes the operation of all relevant additional equipment where that equipment is integral to the injection blow moulding process.

hand tools used in the injection blow moulding process
material loading equipment used for loading of raw materials
relevant personal protective equipment.
Hazards
Typical hazards include:
spills
dusts/vapours

mould/tooling problems.
Variables
Key variables to be monitored include:
operating temperatures
speed
cycle time
output rate
concentration or dispersion of colour
product weight
product wall thickness
product integrity and general conformance to specification/sample.
Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
