Agricultural Dust Explosions
Grain dust explosion prevention: Grain dust explosions are a hazard faced by any industry handling grain-based materials. Our research has shown that grain dust explosions have been occurring at a constant rate in the US over the past decade. We conduct hazard awareness and safety training amongst workers in grain elevators, feed mills, and grain processors.

Grain dust explosion incidents in the U.S.: Our group has been involved in collecting data related to grain dust explosions in the US since 2012. This initiative is supported by the National Grain and Feed Association (NGFA).
