Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

The assessment process must address all of the following items of evidence.

Ability to:

1. Access workplace information ash separation requirements

2. Select, fit and use personal protective clothing and/or equipment

3. Confirm status of equipment and that services are available

4. Conduct pre-start checks

5. Demonstrate start up procedures for preparing and operating each equipment component in the system

6. Demonstrate safe chemical preparation and handling

7. Monitor the ash separation system. This typically includes visual inspection and conducting tests to monitor characteristics such as:

moisture content of ash going out of the system

available storage capacity of ash holding area

filter performance and condition

8. Take corrective action in response to abnormal or unacceptable performance

9. Report and/or record corrective action as required

10. Demonstrate shift handover procedure and confirm that replacement operators are aware of equipment status and operating requirements prior to completing handover

11. Record operating information

12. Maintain work area to meet housekeeping standards

May include ability to:

13. Use process control systems

Knowledge of:

14. Relevant state OHS legislation, standards and codes of practice relating to work responsibilities

15. Safe work procedures including awareness of health and safety hazards related to operation of the ash removal system and associated control measures. Hazards typically include working with airborne particulates containing silica, chemical handling and use of hot water

16. Purpose and limitations of protective clothing and equipment

17. Methods used to render equipment safe to inspect, maintain and/or clean including lock-out, tag-out and isolation procedures

18. Properties of ash or soot and the impact on filter operation

19. Functions and operating principles of ash separation system and related equipment

20. Relationship between vacuum, filter speed and cake permeability

21. Operating requirements and parameters

22. Test methods

23. Common causes of variation and corrective action required

24. Procedures for responding to emergency situations. This includes safe shutdown procedure

25. Handover and long term shut down and storage procedures

26. Environmental issues and controls

27. Procedures for containing and managing ash spills

28. Housekeeping standards for the work area

29. Reporting and recording systems

May include knowledge of:

30. Basic operating principles of process control where relevant. This includes the relationship between control panels and systems and the physical equipment

Relationship with other standards

Pre-requisite units

There are no pre-requisite units for this competency standard.

Co-assessment of related units

Other units of competency relevant to the work role should be assessed in conjunction with this unit. This may include:

SUGZPCI2A Operate a process control interface

Resources required for assessment

Assessment must occur in a real or simulated workplace where the assessee has access to:

Ash separation system and related equipment

Relevant codes and standards

Operating procedures and related advice on equipment operation

Personal protective clothing and equipment

Communication systems and equipment

Housekeeping standards and procedures

Workplace information recording systems, requirements and procedures

Assessment requirements

For information on how to assess this competency standard and who can assess, refer to the Assessment Guidelines for this Training Package.


Submission Requirements

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Not applicable.

The range statement indicates the context for demonstrating competence. This statement is a guide and unless otherwise indicated, items may or may not apply as required by the work context.

Work is carried out in accordance with company policies and procedures, licensing requirements, manufacturer's recommendations, legislative requirements, codes of practice and industrial awards and agreements. Codes of practice include the Sugar Milling Operations Industry Code of Practice

Workplace information can include Standard Operating Procedures (SOPs) and manufacturer's specifications

Equipment may include grate cleaning system, ash and soot blowing equipment, ash removal system, pumps, weirs, tanks, belt and rotary filters, chemical addition systems and clarifier

Ash separation may involve use of clarifiers followed by a filter, use of screens or by filter only

Services may include general mill water supply, power and mill and instrumentation air

Chemicals may include caustic soda and flocculants

Typical test requirements include pH, settling tests, clarity or turbidity

Confirming equipment status involves conducting relevant pre-start checks, confirming that housekeeping standards are met, all safety guards are in place and equipment is operational

Operation and monitoring of equipment and processes may require the use of control panels and systems

Work may require the ability to work within a team environment

Information systems may be print or screen based

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
