Evidence Guide
Evidence guide
The assessment process must address all of the following items of evidence.
Ability to :
1. Access workplace information to identify production requirements
2. Select, fit and use personal protective clothing and/or equipment
3. Confirm supply of necessary materials and services
4. Draw mud from the clarifier and assess mud quality
5. Confirm equipment status and condition
6. Set up filters and start up the process
7. Assess requirement for mud conditioning and add materials as required
8. Monitor the process and equipment operation to maintain the process within the required parameters. This typically involves visual inspections and conducting tests to monitor characteristics such as:

- clarifier mud levels and quality
- filter speed and cake thickness
- filtrate clarity and pH
- mud pol and moisture
- equipment condition including filter vacuum and scraper and screen condition
- wash water flow and temperature
9. Take corrective action in response to out-of-specification results
10. Report and/or record corrective action as required
11. Record workplace information
12. Demonstrate shift handover procedure
13. Shut down equipment in response to an emergency situation
14. Demonstrate an operational shut down procedure
15. Prepare equipment for cleaning/maintenance
16. Maintain work area to meet housekeeping standards
May include the ability to :
17. Use process control systems

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:
- SUGPCPS2A Collect and prepare samples
- SUGPPST2A Conduct standard tests
- 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:
- Operating procedures and related advice on equipment operation including advice on safe work practices and environmental requirements
- Personal protective clothing and equipment
- Product and process specifications and operating parameters
- Mud filtration equipment
- Mud to be filtered
- Services as required
- Material Safety Data Sheets where appropriate
- Housekeeping standards and procedures
- Advice on environmental management issues relevant to work responsibilities
- Workplace information recording systems, requirements and procedures
They may also require
- Cleaning procedures, sampling schedule and procedures and maintenance procedures and tools depending on the work requirements.
Assessment requirements
For information on how to assess this competency standard and who can assess, refer to the Assessment Guidelines for this Training Package.
Range Statement
Range statement
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, 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), specifications, production schedules and manufacturer's specifications
- Mud filtration equipment may include clarifier mud removal, mud tank/mud mixer, bagacillo system, filtrate receivers and pump, vacuum pumps, mud filter, mud conveying system and storage, filter wash water supply, lime, flocculant and filtrate recycle to mud system
- Confirming equipment status involves conducting relevant pre-start checks, confirming that cleaning standards are met, all safety guards are in place and equipment is operational. It may also involve checking operation/calibration of measuring instrumentation
- Operation and monitoring of equipment and processes typically requires the use of control panels and systems
- Services may include power, water, compressed and instrumentation air
- Materials can include lime, flocculants, saccharate and preservatives
