The AS2628 was developed to form a common definition of a gas-tight, sealable silo which is suitable for fumigation. For a silo to meet the AS2628 it must perform a five minute, half-life pressure test. If a silo meets this pressure test, it will hold phosphine gas and other fumigants at a concentration high enough and for long enough to kill insects at all life stages (eggs, larvae, pupae). For more information see ‘Pressure testing sealable silos’

The first thing to ask yourself is do I want the option to fumigate in the silo? If the answer is yes then you will need a gas-tight, sealable silo that meets the Australian Standard 2628. Ensure the manufacture or importer can guarantee this by performing a five minute, half-life pressure test once the silo is delivered or constructed. Getting it stated on the invoice is also a good idea as this forms part of your guarantee. For more tips on buying silos see ‘Silo buyer’s guide’

Where do insects live and can I clean up to keep them away from my storage? A Insects typically like warm dark area’s with a source of food. Common places to find insects are in leftover bags of grain, under hoppers, in machinery where grain gets caught and under rubbish around storages. Cleaning grain storages, surrounding areas and grain handling machinery is the first line of defence against insects.
