Elements and Performance Criteria

1. Assess the need for fumigation.
   • Ascertain the threshold level of infestation against quality requirements and industry practice.
   • Determine the need for fumigation as an option within an Integrated Pest Management (IPM) and IRM strategy.
   • Determine the appropriate fumigation method with regard to pest type, facility and storage/growing conditions.
   • Undertake a cost-benefit analysis of fumigation.
2. Determine type and method of fumigation
   • Select method of fumigant application to suit type of pests, facility and grain/plant type in accordance with manufacturer's specifications, environmental, legislative, Occupational Health and Safety (OHS) requirements and industry practice.
   • Determine type of fumigant and application rate in accordance with manufacturer's specifications, standards and environmental, legislative, OHS and industry practice.
   • Assess appropriateness of facility and conditions for selected fumigation method.
   • Identify and report any factors affecting the safe application of fumigants.
   • Determine facility capacity to ensure fumigation conditions are in accordance with manufacturer's specifications and environmental, legislative, OHS and industry practice.
3. Prepare storage facility for fumigation
   • Assess hazards and control risks in relation to the use of fumigants in accordance with legislative, environmental, OHS requirements and industry practice.
   • Establish security measures to control access during fumigation and prescribed re-entry periods in accordance with label directions.
   • Erect signage and barriers to control risk of inadvertent entry to facility.
   • Apply sealing methods as appropriate to contain fumigant in accordance with label and industry practice.
   • Check seal, calculate volume of storage facility, and take appropriate measurement to ensure the required concentration of fumigant is retained in accordance with label directions.
   • Set up emergency and confined spaces systems in accordance with legislative and OHS and requirements.
4. Prepare application equipment and fumigant(s)
   • Select and use appropriate personal protective equipment in accordance with label and Material Safety Data Sheets (MSDSs) requirements.
   • Select application equipment appropriate for the fumigation in accordance with label directions and industry practice.
   • Check operational effectiveness of equipment in accordance with manufacturer's specifications and industry practice.
   • Calibrate fumigation equipment to application rate in accordance with label directions.
   • Prepare fumigant in accordance with label legislative and OHS requirements and industry practice.
5. Conduct fumigation
   • Apply fumigation using appropriate equipment, fumigation methods and sealing methods in accordance with label and industry practice.
   • Respond to emergency situations using emergency response procedures in accordance with legislative and OHS requirements and industry practice.
6. Monitor fumigation
   • Monitor fumigation site during exposure time and ventilation to prevent unauthorised access in accordance with legislative and OHS requirements and industry practice.
   • Maintain integrity of seals throughout the active fumigation period in accordance with label, legislative and OHS requirements and industry practice.
7. Ventilate storage facility
   • Establish ventilation and re-entry times and control risks to public health and safety in accordance with label, legislative, OHS requirements and industry practice.
   • Ventilate facility to remove fumigant in a safe and controlled manner in accordance with label, legislative, OHS and industry practice.
   • Test for evidence of residual gas using appropriate equipment.
   • Notify appropriate person(s) of any further risk control measures required in accordance with label, legislative, OHS and industry practice.
8. Restore storage facility
   • Collect and remove all equipment, fumigants and waste in accordance with label, legislative, OHS and industry practice.
   • Remove signage and barriers when facility is available for re-use in accordance with legislative and industry practice.
   • Restore storage facility in accordance with legislative and industry practice.
9. Clean, safety-check and store equipment and fumigants
   • Clean, decontaminate, check and store equipment and Personal Protective Equipment (PPE) in accordance with manufacturer's specifications, OHS and industry practice.
   • Transport and store fumigants in accordance with label, OHS and industry practice.
   • Dispose of all waste in accordance with label, legislative, OHS environmental and industry practice.
10. Record fumigation details
    • Record details of fumigant applications in accordance with legislative and quality assurance requirements and industry practice.
    • Record and report gas escapes, safety incidents or poisoning to the appropriate person or authority in accordance with legislative requirements.
