Required Skills

Required skills

Required skills include recognising conditions which will lead to out of specification product and taking appropriate action implementing enterprises procedures and relevant regulatory requirements within time constraints and in a manner relevant to the operation of the equipment reading and numeracy to interpret workplace documents and technical information

Required knowledge

Required knowledge includes source and properties of typical raw materials operation of the preparation equipment consistency of the prepared materials distinguish between causes of faults such as material variations specification or recipe tolerance equipment malfunction

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	Competence must be demonstrated in the ability to recognise situations requiring action and then in implementing appropriate corrective action Consistent performance should be demonstrated In particular look to see that raw materials are correctly selected preparation is as specified completed products meet specifications performance of materials is as required
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	This unit may be assessed in conjunction with PMCB Operate equipment to blendmix materials PMC552002B Operate equipment to blend/mix materials. 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
Materials	Materials may include: additives body materials glaze pigments and stains slip waste
Equipment	Equipment may include: ball mill blunger bobcat box feeder filter press and filters fine rolls fork lift truck front end loader hammer mill hygrometer magnet mortar and pestle power consumption gauge pug mill rotameter sieves and screens spray drying tower storage room tanks and silos tempering machine thermometer timing equipment weighing equipment PLCs scrapper penetrometers balances infrared microwave
Processes	Processes may include: batch continuous dry materials wet materials
Typical problems	Typical problems may include: adjustments to allow for materials variations equipment malfunction contamination
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
