Appendix 4: Requirements for AWPCS sulfuryl fluoride fumigation providers
- 4.9 Sheet fumigation
- for tarpaulin fumigation, use a tarp of highly resistant material such as vinyl coated nylon, or polyethylene sheeting of at least 0.15 millimetres (150 microns) thickness. All seams are to be sealed to create a gas-tight enclosure. Low edges of the tarp are to be weighted down, for example with sand
- for sulfuryl fluoride, a fumigant of low water solubility, ground surrounding the structure is moistened with water to act as a barrier to the gas
