Elements and Performance Criteria

1. Plan fumigation
   • Determine the need for fumigation as an option within an Integrated Pest Management (IPM) and Integrated Resource Management (IRM) strategy
   • Determine type of fumigant and application rate
   • Select method of fumigant application to suit type of pest, facility and grain or plant type
   • Assess appropriateness of facility and conditions for selected fumigation method
   • Select and use appropriate personal protective equipment as per label instructions.
2. Prepare storage facility for fumigation, application equipment and fumigants
   • Identify hazards, assess risks and implement control measures in relation to the use of fumigants in enclosed spaces
   • Establish security measures to control access during fumigation and prescribed re-entry periods
   • Erect signage and barriers to control risk of inadvertent entry to facility
   • Check seal, calculate volume of storage facility, and take appropriate measurement to ensure the required concentration of fumigant is retained
   • Check operational effectiveness of equipment
   • Calibrate fumigation equipment to deliver the correct application rate
   • Transport and store fumigants
   • Prepare fumigant in accordance with label instructions
3. Conduct and monitor fumigation
   • Apply fumigation using appropriate equipment, fumigation methods and sealing methods
   • Respond to emergency situations using emergency response procedures
   • Monitor fumigation site during exposure time and ventilation to prevent unauthorised access
   • Maintain integrity of seals throughout the active fumigation period
4. Ventilate storage facility
   • Establish ventilation and re-entry times and control risks
   • Ventilate facility to remove fumigant in a safe and controlled manner
   • Test for evidence of residual gas using appropriate equipment
   • Notify appropriate personnel of any further risk control measures required
5. Restore storage facility
   • Collect and remove all equipment, fumigants and waste
   • Remove signage and barriers when facility is available for re-use
   • Restore storage facility
6. Clean, safety-check and store equipment and fumigants
   • Clean, check, decontaminate and store equipment and personal protective equipment in appropriate location
   • Dispose of all waste as per label instructions
7. Record fumigation details
   • Record details of fumigant applications
   • Record and report gas escapes, safety incidents or poisoning to the appropriate person or authority
