Overview of assessment

Assessment must be carried out in a manner that recognises the cultural and literacy requirements of the assessee and is appropriate to the work performed

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Evidence of ability to

prepare lime flocculant and saccharate for addition

set up and start up the process in both automatic and manual modes

monitor the process and equipment operation

take corrective action in response to outofspecification results

record workplace information

demonstrate shift handover procedure

shut down equipment in response to an emergency situation

Context of and specific resources 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

Juice clarification equipment

Materials including raw juice to be clarified

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

Method of assessment
