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
- Evaporator and related equipment
- Materials to be evaporated
- 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
- 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
- Evaporation equipment may include heat exchangers, vapour separators, vapour condensers, vacuum and condensate pumps. Evaporators may have single or multiple stages and effects
- 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
- Operation and monitoring of equipment and processes typically requires the use of control panels and systems
- Services may include power, steam, water, vacuum, compressed and instrumentation air
- Materials can include anti-scalants and enzymes
- Where tests are conducted as part of operation, typical requirements are for brix and thymol testing
- Monitoring the process may involve the use of production data such as performance control charts
- Control points refer to those key points in a work process which must be monitored and controlled
- Work may require the ability to work within a team environment
- Information systems may be print or screen based
