Elements and Performance Criteria

1. Determine type and method of fumigation
   • Identify the nature and level of pest presence
   • Determine need for fumigant use within an Integrated Pest Management (IPM) strategy
   • Determine type of fumigant and application rate
   • Select method of fumigant application to suit type of pests and site
   • Determine volume to be fumigated to ensure fumigation conditions are met as per label instructions
   • Conduct and record work health and safety risk assessment for both fumigation and post fumigation re-entry
2. Prepare to use fumigant according to label and SDS
   • Select appropriate personal protective equipment (PPE) as per label requirements and check for effectiveness
   • Define and calculate application/dosage rates
   • Erect prominent signage notifying passers-by of fumigation operation in progress
   • Identify hazards, assess risks and implement control measures
   • Prepare fumigation site to control inadvertent entry or exposure
   • Implement emergency procedures as required
3. Conduct fumigation
   • Confirm first aid equipment is available onsite
   • Assess weather conditions and forecasts prior to and during application
   • Create airtight seal in fumigation area to ensure maximum effectiveness of fumigation
   • Signpost and barricade fumigation site where required to prevent access
   • Apply fumigant safely and effectively in accordance with label requirements
   • Control site until area is suitable for re-use
   • Transport and store fumigants as required
4. Monitor fumigation
   • Monitor fumigation site to control access and maintain safe conditions during active period for the time specified on the label
   • Monitor fumigation site for pest activity
   • Assess fumigant escape safety implications and take immediate action if required
5. Ventilate fumigated area
   • Follow label direction to determine when conditions are suitable for ventilation to minimise risk to health and safety
   • Calculate time required for ventilation
   • Ventilate site in accordance with registered label, SDS, Code of Practice and enterprise standards
6. Clean up following fumigation
   • Remove barriers, signs and locks and store for future use in appropriate location
   • Clean, decontaminate, check and store equipment and personal protective equipment in appropriate location
   • Transport and store fumigants in accordance with label, legislative and industry practice
   • Dispose of all waste as per label instructions
7. Record application details
   • Record details of fumigant applications
   • Record details of fumigant used in the chemical inventory or register
   • Maintain inventory of personal protective equipment
   • Follow procedures and requirements for reporting fumigation details to management/employer
   • Record and report safety incidents or poisoning to the appropriate person or authority
