Automation to control silica dust during the pallett loading process.
Min Eng 1991 Dec; 43(12):1440-1443
Two recent U.S. Bureau of Mines studies evaluated workers' dust exposures in automated pallet loading processes. The first study involved a Bureau-designed dust control system using a push-pull ventilation technique. The unit was shown to reduce workers' dust exposures by 76 pct during pallet loading at a ground silica operation. A hydraulic lift table was used to automate the bag stacking process. This kept the loading height constant throughout the entire pallet loading cycle. The second study evaluated different commercial, automated-pallet loading systems. These systems automatically stack the bags onto pallets, shrink wrap the pallets, and deliver the pallets to a fork lift pickup location. Results from a ground silica evaluation site indicated respirable dust samples taken were below the threshold limit value as established by the Mine Safety and Health Administration.
