Interior Grain Bin Ladders
Do not rely on a rope, chain, or pipe ladder hanging from the roof. These are not reliable and may obstruct grain flow during filling or increase drag during unloading. Add an internal ladder on the wall inside the bin. When adding a ladder, consider painting it (the ladder itself) or the wall behind it a bright color. This will help make it easier to locate in dusty conditions.
When using ladders, always maintain 3 points of contact. Either two hands and one foot, or two feet and one hand. This increases your overall safety while on the ladder and greatly reduces the chances of a fall.
Safety Harnesses and Lifeline System

Safety harnesses are preferred to rope or a safety belt, since a belt or a loop of rope around the waist or under the arms can inflict severe injuries if a fall occurs.
Producers should also consider adding a safety harness to their “toolbox” of safety items to use when working in their bins. A body harness is better than a waist belt or a loop of rope around the waist or under the arms, since the harness spreads the force of a fall over a larger part of the body. A waist belt or a loop of rope can inflict severe injuries when used to stop a fall. Consider purchasing fall prevention and protection equipment from a safety gear manufacturer or retailer who has experience with these devices.
When entering a bin, always use a harness with a lifeline system. Never work alone. Have a partner on the outside of the bin that is in contact with the person entering the bin.

While these items all have some level of cost associated with them, using them may help to prevent you from becoming a farm safety statistic. For additional information, see the following references as and resources.
