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. 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 operations
Equipment and operations may include:
instrument panels (local)
measuring and recording equipment
communication equipment
hand tools
emergency stop buttons and lanyards
personal protective equipment
grinding mills
pneumatic conveying systems
slurry pumps
dust collectors
mixing and blending silos
vibrating screens
kilns
bulk storage silos
heat recovery systems
Typical problems
Typical problems may include:
equipment malfunctions
temperature fluctuations
quality of product
material/feed variations
spillages and leakages
inaccuracies in blending and proportioning of raw materials
out of specification moisture content of raw materials/slurry
variations in temperature, time and cooling rates
variations in feed rates or quantities
vibration
Occupational health and safety (OHS)
The identification and control of hazards and the application of OHS are to be in accordance with current, applicable legislation and regulations, and company procedures. All work is carried out at all times in accordance with these requirements

EVIDENCE GUIDE
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 process be understood and that the importance of critical material properties, settings and readings is known. 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:
temperatures are maintained within limits
quality is monitored to minimise wastage
process measurements are continually made or observed.
Competence must be demonstrated in the operation of all ancillary equipment to the level required for this unit of competency.

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 studies/scenarios 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 'walk-throughs' of the relevant competency components. A bank of scenarios/case studies/what 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.
Individual enterprises may choose to add prerequisites and co-requisites 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.
