Foreword and Acknowledgements If your company has a policy of not allowing employees into bins with the sweep auger running we are not suggesting you change that policy. The information shared today will not prevent you from getting a citation from OSHA for having an employee in the bin with the sweep auger running. We are not back to business as usual!
Foreword and Acknowledgements The information being presented is not National OSHA policy but rather a look at the settlement of a case from the Area Office in Peoria, Illinois. We are deeply grateful for the commitment of financial resources and the work done by Western Grain Marketing and GROWMARK. We also wish to commend Tom Bielema and John Lee for their part in this settlement.
