Elements and Performance Criteria

1. Determine blend/mix requirements
   • Check work schedule/job specification/job card
   • Identify customer requirements and set parameters in accordance with standard procedures
   • Select correct type and quantity of materials
   • Meet all special requirements and specifications
   • Identify any material handling problems and take action in accordance with standard procedures
   • Update material records as appropriate
2. Control hazards
   • Identify hazards from the materials
   • Identify other hazards in blending/mixing work area
   • Assess the risks arising from those hazards
   • Implement measures to control those risks in line with procedures
3. Blend/mix materials
   • Set up, start and operate blending/mixing equipment as required by specifications and standard procedures
   • Prepare and add materials to blender/mixer as required by specification and standard procedures
   • Check that materials prepared match requirements
   • Use ancillary equipment as required according to standard procedures
   • Ensure equipment is operated in accordance with established enterprise procedures
   • Blend/mix materials to obtain required results
4. Monitor and record operation
   • Monitor equipment performance in accordance with work instructions and manufacturer's specifications
   • Monitor non-conforming product against customer specifications
   • Adjust and control equipment to ensure correct product quality
   • Complete final inspection checks
   • Complete appropriate records and logs
5. Rectify routine problems
   • Identify the range of faults that can occur during the operation
   • Determine and rectify fault causes in accordance with procedures/work instructions
   • Identify and rectify equipment failure causes in accordance with procedures/work instructions
   • Ensure appropriate records and log books of equipment operations are maintained to meet procedures/work instructions
   • Identify non-routine problems and report to designated person
6. Maintain blending/mixing plant and area
   • Keep area and equipment clean and in good order
   • Unload and shut down equipment as required
   • Respond to routine faults according to enterprise procedures
   • Report non-routine faults according to enterprise procedures

Required Skills

Required skills

Required skills include recognising conditions which will lead to out of specification product implementing the enterprises procedures within time constraints and in a manner relevant to the correct use of the equipment conveying information relevant to the operation clearly and effectively maintaining appropriate levels of quality assurance reading and numeracy to interpret workplace documents and technical information

Required knowledge

Required knowledge includes hazards associated with the process application of the hierarchy of control in controlling the hazards selection use and maintenance of relevant personal protective equipment PPE material handling requirements principles of blendingmixing these products impact of variations in materials on final product impact of blendingmixing on final product impact of variations in product specification of the blendingmixing process properties of the mix equipment limitations and impact on blendingmixing efficiency and effectiveness enterprise production schedules underlying causes of faults such as precipitated by material equipment blendingmixing timetechnique

Evidence Required

The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria required skills and knowledge range statement and the Assessment Guidelines for the Training Package
Overview of assessment	The unit will be assessed in as holistic a manner as is practical and may be integrated with the assessment of other relevant units of competency
Critical aspects for assessment and evidence required to demonstrate competency in this unit	It is essential that the equipment be understood and that the importance of critical material properties settings and readings is known Competence must be demonstrated in the operation of all ancillary equipment to the level required for this unit of competency Competence must be demonstrated in the ability to recognise and analyse potential situations requiring action and then in implementing appropriate corrective action Consistent performance should be demonstrated In particular look to see that hazards are identified and controlled blendmix properties are kept within limits quality is monitored to minimise wastage process measurementsobservations are continually made all OHS requirements are followed problems are anticipated and appropriate action is taken ie problem fixed or reported
Context of and specific resources for assessment	Assessment will require access to an operating plant over an extended period of time or a suitable method of gathering evidence of operating ability over a range of situations Assessment will occur over a range of situations which will include disruptions to normal smooth operation Simulation or case studiesscenarios may be required to allow for timely assessment of parts of this unit of competency Simulation should be based on the actual plant and will include walkthroughs of the relevant competency components A bank of scenarioscase studieswhat ifs and questions will be required to probe the reasoning behind observable actions
Method of assessment	In all plants it may be appropriate to assess this unit concurrently with relevant teamwork and communication units It may also be appropriate to assess this unit in conjunction with MSACA Undertake manual handling MSAC112003A Undertake manual handling. Individual enterprises may choose to add prerequisites and corequisites relevant to their processes
Guidance information for assessment	Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed

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. Bold italicised wording, if used in the performance criteria, is detailed below. 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) may also be included.
Procedures	All operations are performed in accordance with standard procedures and work instructions.
Equipment and unit operations	All such items of equipment and unit operations must form part of a discrete blending/mixing system. These may include: pumps (lubrication and cooling pumps) utilities and services heat exchangers (intercoolers) vibration monitoring other equipment integral to the operation of the compressor system
Typical problems	Typical problems may include: equipment malfunction material handling such as equipment failure and blockages material property variation blend/mix tolerance uniform dispersion of minor ingredients/additives blending/mixing to special requirements/colour mixing sequence matching mixes produced with production requirements monitoring and adjusting process conditions recognising and acting on potential and actual problems quality problems including customer requirements
Occupational health and safety (OHS)	All operations are subject to stringent OHS requirements and these must not be compromised at any time. Where there is an apparent conflict between performance criteria and OHS requirements, the OHS requirements take precedence
