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
Materials
Materials may include:
quarried materials
feedstock
waste materials
ground minerals industries
concrete waste
Equipment and unit operations
This unit of competency includes all such items of equipment and unit operations which form part of the crushing system. These may include:
jaw crushers
cone crushers
grizzlies
grids
other equipment integral to the operation of the crushing system
Typical problems
Typical problems may include:
difficult material to be crushed
variations in temperature and moisture
variations in feed
product discharge problems
blocked screens
oversized feed
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 and process be understood and that the importance of critical material properties is known. Competence must be demonstrated in the ability to recognise and analyse potential situations requiring action and then in reporting the condition to the appropriate individual.
Consistent performance at the required standard should be demonstrated. In particular look to see that:
types of materials to be crushed are identified
individual material feed and distribution systems are understood
OHS and safe work practices are followed
signage, tags and isolation procedures are followed
basic maintenance and inspection practices are carried out.
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
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.
