Storage bins, bunkers, hoppers, and silos where unconsolidated bulk materials are stored, handled or transported shall be equipped and maintained as follows:
1. Equipped with mechanical devices or other effective means of handling materials so that during normal operations persons are not required to enter or work where they are exposed to entrapment by caving or sliding of materials.
2. Equipped with supply and discharge operating controls. The controls shall be located so that spills or overruns will not endanger persons.
3. Where persons are required to move around or over any storage bin, bunker, hopper, or silo where unconsolidated bulk material is stored, handled or transported, suitable walkways or passageways shall be provided.
4. Ladders, platforms, or landings shall be provided for maintenance or inspection purposes where persons are required to enter any storage bin, bunker, hopper, or silo where unconsolidated bulk material is stored, handled or transported. No person shall enter the facility until the supply and discharge of materials has ceased and the supply and discharge equipment is de-energized, locked out and suitably tagged. Persons entering the facility shall wear a safety belt or harness equipped with a safety line. A second person, similarly equipped, shall be stationed near where the safety line is fastened and shall constantly adjust it or keep it tight as needed, with minimum slack.
