5.2. Assess the risks arising from those hazards

5.3. Implement measures to control those risks in line with procedures

5.4. Shut down in an emergency as required

Required Skills and Knowledge

REQUIRED SKILLS AND KNOWLEDGE 

This section describes the skills and knowledge required for this unit.

Required skills 

Required skills include:

  • recognising process conditions which will lead to out of specification production and taking appropriate action
  • implementing the enterprise's standard procedures and work instructions and relevant regulatory requirements within appropriate time constraints and in a manner relevant to the operation of grinding equipment
  • reading and numeracy is required to the level of interpreting workplace documents and technical information

Required knowledge 

Required knowledge includes:

  • startup and shutdown processes
  • construction and limitations of the grinding equipment and conditions
  • grinding fundamentals
  • out of specification situations
  • physics and chemistry (where appropriate) of process
  • principles of operation of process
  • control philosophy of process
  • distinguish between causes of faults such as:
  • raw material variations
  • mechanical abnormalities
  • electrical/instrument reading variations

Evidence Guide

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 ground and their additives 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.

Range Statement

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.

Ground materials 

Ground materials may include:

  • quarried materials
  • cement clinker
  • lime
  • ceramics and clay
  • ground minerals
  • glass
  • concrete waste
  • fibre cement

Equipment and unit operations 

All such items of equipment and unit operations which form part of the grinding system. These may include:

  • ball mills
  • hammer mills
  • roller mills
