2.5. Clear and accurate records of grain movements in and out of storage are created, maintained and kept as prescribed in the grain storage program.
2.6. Recommendations are made to adopt new technology, systems or practices that will improve or maintain grain quality in storage.
2.7. All activities around the grain storage facilities are undertaken according to the Occupational Health and Safety (OHS) guidelines detailed in the grain storage program.
3. Monitor and maintain grain condition in storage
3.1. Regular checks of grain in storage are conducted to maintain continued freedom from contaminants and deterioration.
3.2. Periodical checks of grain in long-term storage are conducted for quality factors and viability according to enterprise requirements.
3.3. Where necessary, samples of the grain are taken for testing in a laboratory setting.
3.4. Where test samples are required, they are taken, prepared, and forwarded for analysis according to industry quality assurance and laboratory requirements.
3.5. Clear and accurate records of grain tests and inspections are created, maintained and kept as described in the grain storage program.
3.6. The condition of storage facilities is monitored using the schedule and methods outlined in the grain storage program.
3.7. Where it is required, appropriate corrective action is taken to maintain grain quality.
3.8. All activities around the grain storage facilities are undertaken according to the OHS guidelines detailed in the grain storage program.
4. Control weeds and pests in storage are
4.1. Grain is monitored according to the monitoring points, targets and methods outlined in the grain storage program.
4.2. Samples of the grain are appropriately taken to test for pest infestation.
4.3. Where it is required, the sample is prepared and forwarded for analysis according to the prescribed guidelines.
4.4. Pests in storage are controlled according to the guidelines in the grain storage program.
4.5. Enclosed grain storage area is fumigated, and the surrounding environment is kept clean according to the integrated pest management strategy in the grain storage program.
4.6. The sources of any infestations are identified and steps are taken to control them in line with the integrated pest management strategy in the grain storage program.
4.7. All pest control activities are undertaken in line with the OHS guidelines detailed in the grain storage program.
4.8. Clear and accurate records of treatments to the grain and storage facilities are created, maintained and kept as described in the grain storage program.
4.9. Clear and accurate records of all chemical use in the storage facility, and the applicable withholding periods are created, maintained and kept as described in the grain storage program.

Overview of assessment
Critical aspects for assessment and evidence required to demonstrate competency in this unit
The evidence required to demonstrate competency in this unit must be relevant to workplace operations and satisfy holistically all of the requirements of the performance criteria and required skills and knowledge and include achievement of the following:
implement pre-determined integrated pest management strategies
monitor and maintain hygiene
monitor and control pests and contaminants
investigate and recommend options for technology, systems or practices that will improve grain quality.
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.
The range statement relates to the unit of competency as a whole.
Factors affecting grain quality in storage may include:
the presence of water or water damage
presence and activity of pests (including insects, moulds, birds and rodents)
dead vertebrate pests in storage
breakdown of storage security and integrity (e.g. holes, cracks, poor sealing, etc.)
grain moisture migration
excessive dust levels
high pesticide and fumigant residues
legal withholding periods.
This unit contains employability skills.
