• Description:
  Due to the use of several exemplary controls at the Company-X (SIC- 1499) operation for packaging chrysotile (12001295) asbestos fibers, a study was conducted at the facility to determine the effectiveness of the operation. Controls evaluated were: the enclosures for the bag filling and bag flattening operations; the exhaust ventilation from these enclosures; the use of both shrink wrapping and stretch wrapping; automated palletizing; and the isolation of the bagger rooms. There were approximately 60 employees at the milling and packaging site. The two packaging stations are isolated from each other and from other operations within the building. Packaging operations include bag filling, conveying, shrink wrapping of paper bags and palletizing. Effectiveness of the control methods for airborne fibers was evaluated quantitatively by taking airborne samples and ventilation measurements. Even in the main bagging rooms, airborne concentrations of asbestos fibers were below 0.9 fibers/cubic centimeter (fibers/cc). Under normal operating conditions, without equipment malfunctions, the average fiber concentrations were nearer 0.3 fibers/cc in this area. By improving the less effective controls in the grinding area in the RG-244 bagging room and at the burst bag hopper recyclers in both bagging rooms, lower airborne concentration levels should be attainable.
