Conduct fumigation in enclosed spaces

Assessment tool

Version 1.0
Issue Date: March 2024


This unit relates to the control of insects and other pests by means of fumigation of grain and seed in storage and crops and plants grown in protected environments. These storage areas and protected environments may be deemed to be confined spaces "in situ" or be deemed to be confined spaces because of the impact of the fumigation activities.

This unit covers the process of fumigation of grain, seed, crops and plants in enclosed spaces and defines the standard required to: assess the need for fumigation; select appropriate fumigant and application method; prepare and monitor storage facility and equipment; apply fumigant; restore facility and clean equipment; record work activities.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)
