Application

This unit of competency describes the skills and knowledge required to use application equipment to fumigate grain, seed, crops and plants housed in enclosures or confined spaces.

The unit applies to individuals who work under broad direction and take responsibility for their own work. They use discretion and judgement in the selection, allocation and use of available resources and for solving problems.

State or territory licensing, legislative or certification requirements apply in some jurisdictions for the purchase and use of fumigants.

Performance Evidence

An individual demonstrating competency must satisfy all of the elements and performance criteria in this unit. There must be evidence that the individual has on at least one occasion demonstrated the ability to safely apply a fumigant on materials housed in an enclosure, ensuring they have:

  • determined need, appropriateness and method for fumigating a storage facility
  • determined hazards and risks and established safety and security resources and control measures required
  • prepared facility for safe fumigation
  • determined fumigant requirements and prepared the fumigant and equipment for treatment according to chemical label instructions and safety data sheets (SDS)
  • ensured personal safety by using appropriate personal protective equipment (PPE)
  • applied fumigant and monitored the safety and integrity of the fumigation process, responding appropriately to emergencies
  • rendered the storage facility safe through ventilation, conducted tests to establish safe air quality notifying personnel of residual risks
  • removed fumigation materials, waste and temporary resources from storage facility and disposed of waste according to workplace and environmental procedures
  • complied with workplace and environmental procedures and chemical label instructions and SDS
  • checked, decontaminated, cleaned and stored equipment used in the fumigation process according to workplace procedures
  • maintained records of fumigation activities and incidents and reported according to workplace procedures.
