Prerequisite units

There are no prerequisite units for this competency standard

Coassessment of related units

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

SUGPCPSA Collect and prepare samples

SUGPPSTA Conduct standard tests

SUGZPCIA Operate a process control interface

Resources required for assessment

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

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

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
