Elements and Performance Criteria

ELEMENT	PERFORMANCE CRITERIA
1. Set up and prepare gravity table for use	1.1. A gravity table is and set up and prepared to job requirements and confirmed against work plan. 1.2. Routine pre-operational checks of the gravity table are completed to manufacturer's specifications and enterprise requirements. 1.3. Occupational Health and Safety (OHS) hazards in the workplace are recognised, risk assessed and minimised according to enterprise requirements.
2. Operate a gravity table to process seed	2.1. The gravity table is operated in a safe and controlled manner and monitored for performance and efficiency. 2.2. Risks to self, others and the environment are anticipated and minimisation strategies implemented accordingly. 2.3. Suitable personal protective clothing and equipment is selected, used, maintained and stored according to OHS requirements. 2.4. Environmental implications associated with machinery operation are identified, assessed and reported to the supervisor.
3. Complete and report on seed cleaning operation	3.1. Shut-down procedures for the gravity table are completed to manufacturers' specifications and enterprise requirements. 3.2. Operational records are completed and maintained according to enterprise requirements. 3.3. Malfunctions, faults, observation of irregular performance and damage to the gravity table are detailed and reported according to enterprise requirements. 3.4. The gravity table is cleaned according to OHS and enterprise requirements.

Evidence Guide

EVIDENCE GUIDE
The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.
Overview of assessment
Critical aspects for assessment and evidence required to demonstrate competency in this unit	In order to confer competency, evidence must prove that the candidate is able to: set up and prepare gravity table for use operate a gravity table to process seed, and complete and report on seed cleaning operations.
Context of and specific resources for assessment	Competency requires the application of work practices under work conditions. Selection and use of resources for some worksites may differ due to the regional or enterprise circumstances.

Range Statement

RANGE STATEMENT
The range statement relates to the unit of competency as a whole.
Gravity table operations may include:	all gravity type separators using the principles of stratification which involves dividing seed into a series of graded statuses by the use of air shake and angle to achieve a separation of seed density or specific gravity any variation of these machines, with or without additions, to enhance performance.
