WHS Management for Grain Handling

Grain dust receives a WEL for the first time. Silo engulfment and dust explosions are preventable fatality risks.

Grain handling facilities receive, store, dry, transfer, and dispatch grain through silos, elevators, conveyors, and truck loading systems. The incoming WEL of 1.5 mg/m³ for grain dust establishes a formal exposure limit for the first time, requiring facilities to implement monitoring and controls that many have not previously considered necessary. Grain dust is combustible and has caused catastrophic explosions at grain storage and handling facilities worldwide. Silo entry for inspection, cleaning, and unblocking creates engulfment and confined space hazards that have caused multiple fatalities in Australia. The combination of heavy mobile plant, conveyor entrapment, elevated work, and remote locations creates a risk profile that demands comprehensive WHS management.
