Elements and Performance Criteria

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 operators working either independently or as part of a work team.
Procedures:
All operations are performed in accordance with procedures.
Procedures means 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:
hand carts and trolleys
knives and other bag opening equipment
hoists/lifting equipment not requiring any special permits or licences
mixing spatulas or paddles
portable electrical paddle mixers
relevant personal protective equipment.
Hazards:
Typical hazards include:
spills and splashing
noxious fumes and vapours
hazardous materials
manual handling hazards.
Problems:
Respond to/rectify 'non-routine problems' means 'apply known solutions to a variety of predictable problems'. Typical process and product problems may include:
incorrect material composition
over or under mixing
broken mixing equipment
temperature variations.
variations in materials
contamination of materials
variations in setting times.
Variables:
Key variables to be monitored include:
atmospheric conditions
sequencing of material additions to the mix
volumes /mass of materials being mixed
mixing time
amount of moisture.

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
plan and set up work before beginning the hand mixing process.
Consistent performance should be demonstrated. For example, look to see that:
production standards are met consistently
mixing produces a consistent product
timing of mixing batches is consistent with production needs.
Assessment method and context
Assessment will occur using industrial materials and 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.
