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
Product to be made
The product to be made may be determined by consulting the production schedule or similar means
Required setup
Required setup includes:
alignment of all equipment
checks and adjustments according to product specifications and procedures
production schedule requirements
Monitoring
Monitoring includes analysing and interpreting data for:
variations
fluctuations
trends
with a view to establishing stable, efficient operation producing goods as required
Process data
Process data include that from:
equipment
instruments
control panels
test results
Appropriate action
Appropriate action includes adjusting:
temperature controls
equipments settings
process conditions
to ensure process parameters are maintained to job specifications

Process
The process includes:
setting up, monitoring and tuning equipment for optimum performance especially during startup, job change and equipment changes
Typical problems
Typical problems may include:
raw materials supply
equipment alignment
analysis of all plant data
control of temperature within specification
product quality
equipment speed
taking corrective action
Plant data
Plant data may include:
test results
instrument/control panel information
data from physical senses (sight, sound and hearing)
temperatures, pressures, material flow and discharge rates and effects
variations to chemical reactions/material modifications
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

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 equipment 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. The emphasis should be on the ability to stay out of trouble rather than on recovery from a disaster.
Consistent performance should be demonstrated. In particular look to see that:
setup/tuning is completed to specifications
temperature and pressures are maintained within limits
adjustments made are completed in a timely manner in accordance with procedures/work instructions
quality is monitored to minimise wastage
startup and shutdown occur first time
early warning signs of equipment/processes needing attention or potential problems are recognised and dealt with in a timely manner
process measurements are continually made or observed
the range of possible causes can be identified and the most likely cause determined
appropriate action is taken to ensure a timely return to full performance
obvious problems to related plant areas are recognised and an appropriate contribution made to their solution.
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.
