Unit of competency

Modification History

Release 1. Supersedes and is equivalent to PMC552002C Operate equipment to blend/mix materials.

Application

This unit of competency covers the skills and knowledge required to select and blend/mix materials using blending/mixing and ancillary equipment.

This unit of competency applies to operators who are required to select the correct type and quantity of materials, set up and operate equipment, monitor the process, rectify routine problems and conduct routine maintenance.

This unit of competency applies to an individual working alone or as part of a team or group and working in liaison with other shift team members, team leader and supervisor, as appropriate.

Where manual handling forms part of the work the operator will also require competency in PMBHAN103 Shift materials safely by hand .

No licensing, legislative or certification requirements apply to this unit at the time of publication.

Assessment requirements

Modification History

Release 1. Supersedes and is equivalent to PMC552002C Operate equipment to blend/mix materials.

Performance Evidence

Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria and demonstrate the ability to:

• read and interpret instruments/controls, job sheets, procedures, material labels and safety information
• set up and operate the equipment according to procedures
• select and prepare materials to meet job specifications
• monitor key variables, including:

• process conditions/parameters
• duration of blend/mix
• mixing sequence
• blend/mix tolerance
• product integrity and conformance to specification

• adjust the equipment to meet product quality and production output specifications
• pause or shut down equipment in normal and abnormal circumstances
• identify hazards and apply relevant hazard controls
• apply safety procedures
• recognise out-of-specification products, process problems and materials faults
• recognise routine and non-routine problems
• identify when the operator is able to rectify problems, when assistance is required and who is the appropriate source for assistance
• take action to resolve problems or report them to appropriate personnel
• distinguish between possible causes of routine problems, including:

• raw material variations
• process problems
• mechanical abnormalities
• electrical/instrument reading variations
• equipment faults/damage/failure

• communicate effectively with team/work group and supervisors
• complete workplace records
• do basic arithmetical manipulations, including addition, subtraction, division, multiplication, fractions and percentages.

Knowledge Evidence

Must provide evidence that demonstrates knowledge relevant to their job sufficient to operate under routine only supervision and to solve routine problems, including knowledge of:

• principles of blending/mixing products
• principles of operation of the blending/mixing equipment and ancillary equipment that is integral to the process
• basic physics and chemistry relevant to the equipment/process/materials
• impact of blending/mixing on final product
• the potential effects of variations in raw materials and equipment operation/processes in relation to quality of product
• impact of variations in product specification on the blending/mixing process
• factors which may affect product quality or production output and appropriate remedies
• equipment limitations and impact on blending/mixing efficiency and effectiveness
• basis of the process used to transform the feed materials into the product
• product specifications and tolerances
• routine problems, their probable causes and relevant corrective actions
• start-up and shutdown processes
• enterprise production schedules
• organisation procedures relevant to the work environment/job role
• hierarchy of control
• hazards that may arise in the job/work environment and:

• their possible causes
• potential consequences
• appropriate risk controls.

Assessment Conditions

• The unit should be assessed holistically and the judgement of competence shall be based on a holistic assessment of the evidence.
• It may be appropriate to assess this unit in conjunction with:

• MEM11011B Undertake manual handling.

• The collection of performance evidence:

• should occur over a range of situations which include typical disruptions to normal, smooth operation of an operating plant
• will typically include a supervisor/third-party report or other evidence, focusing on consistent performance and problem recognition and solving. A supervisor/third-party report must be prepared by someone who has a direct, relevant, current relationship with the person being assessed and who is in a position to form a judgement on workplace performance relevant to the unit of competency
• must include the use of an appropriate industrial item of equipment requiring demonstration of operation, start and stop procedures and responding to problems
• may use industry-based simulation for all or part of the unit particularly where safety, lack of opportunity or significant cost is an issue.

• Assessment should occur in operational workplace situations. Where this is not possible or where personal safety or environmental damage are limiting factors assessment must occur in a sufficiently rigorous simulated environment that reflects realistic operational workplace conditions. This must cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills.
• Assessment in a simulated environment should use evidence collected from demonstration of skills and one or more of:

• walk-throughs
• pilot plant operation
• industry-based case studies/scenarios
• ‘what ifs’.

• Knowledge evidence may be collected concurrently with performance evidence (provided a record is kept) or through an independent process such as workbooks, written assessments or interviews (provided a record is kept).
• Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.
• Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications associated with this unit.
• The regulatory framework will be reflected in workplace policies and procedures and is not required to be independently assessed.
• Foundation skills are integral to competent performance of the unit and should not be assessed separately.
• Assessors must satisfy the assessor competency requirements that are in place at the time of the assessment as set by the VET regulator.
• In addition the assessor or anyone acting in subject matter expert role in assessment shall demonstrate both technical competency and currency. If the assessor cannot demonstrate technical competency and currency they shall assess with a subject matter expert who does meet these requirements.
• Technical competence can be demonstrated through one or more of:

• relevant VET or other qualification/Statement of Attainment
• appropriate workplace experience undertaking the type of work being assessed under routine and non-routine conditions
• appropriate workplace experience supervising/evaluating the type of work being assessed under routine and non-routine conditions.

• Currency can be demonstrated through one or more of:

• being currently employed undertaking the type of work being assessed
• being employed by the organisation undertaking the type of work being assessed and having maintained currency in accordance with that organisation’s policies and procedures
• having consulted/had contact with an organisation undertaking the type of work being assessed within the last twelve months, the consultation/contact being related to assessment
• conducting on the job training/assessments of the type of work being assessed
• being an active member of a relevant professional body and participating in activities relevant to the assessment of this type of work.
