This booklet was intended to point out the hazards associated with the use of grain handling machinery and suggest practical ways to prevent injury from occurring. The guide itself was divided into five sections: harvesting, transportation, storage, conveying, and processing. The harvesting section discussed power unit safety, roll over protective structures, tractor wheel spacing, extra riders, matching power and load, power take offs and drivelines, shielding, clothing, hitching height and distance, harvesting unit safety, stability, falls, and fires. The transportation unit discussed power unit safety, road safety, hitching wagons, bulk container safety, dump trucks and wagons. The storage unit discussed suffocation, silage structures, bunker silos, falls, fires, explosions, and electrocutions. The unit on conveying discussed avoiding machine contact, guarding, power take offs and drivelines, moving augers and elevators, blower tubes, and loaders. Processing discussed moving components, shields and guarding, power take off safety, grinding and milling hazards, electrical safety, and fire prevention.
