Before working in a grain bin, always turn off the power. Never use objects to unplug running augers. Never enter a bin when unloading equipment is running, whether or not grain is flowing. Do not enter a bin with automatic unloading equipment without locking out the control circuit. Always be cautious when working with grain that has begun to spoil.
Dangers result from molds, blocked flow, cavities, crusting and grain avalanches.
Always be cautious before walking on any surface crust. A breakthrough can plunge a person into flowing or hot grain with little chance of survival. Beware of steep piles of grain. Dislodge the pile with a long pole, rather than with a short shovel. Never allow anyone to ride on trucks equipped with grain beds or gravity dump wagons.
