Grain bags – Fumigation

Stored Grain bag fumigation

Two methods for fumigating and venting grain bags with phosphine have been trialed. While passively venting a grain bag is possible, it takes significantly longer than using a fan to draw the gas out. 

Below is a video of Philip Burrill demonstrating the quicker method of venting using a fan. In the video below that, Chris Warrick demonstrates a passive method and outlines what to expect. 

Always follow label directions and use the specified Personal Protective Equipment.
