Closing the door on dust.
Pit Quarry 1986 May; 78(11):36-37
Although bag technology is continually improving, contamination from bags remains a significant source of dust exposure for workers. Most of the bag contamination is caused by the bag valve. Standard paper, polyethylene, extended polyethylene, double trap, and foam valves were tested for dust reduction capabilities during bag loading, conveying, and pallet loading at a mineral processing plant. When extended polyethylene valves were used, respirable dust at the bag operator location was reduced by 62%, while at the bag stacker location the reduction was 66%.
