A control technology survey of solid material bagging, conveying, and sampling operations at the W. R. Grace (SIC-2819) silica gel facility, Cincinnati, Ohio was conducted on October 20, 1981. The facility employed 190 people in the manufacture of silica gel. Visual inspection of the facility identified five problems in the bagging operation involving excess dust from the bag seal on the fill spout, nonoperational exhaust ventilation on the packer machine, open bag valves on the filled bags, dust on the bag surfaces, and spilled product on the floor. The authors recommend that a method is needed to monitor the bag seal to determine if the seal is tight during filling. A method is also needed to remove dust from the bag surface following the removal of the bag from the valve to reduce dust source. The duct work on the ventilation system needs to be revised. The packing operator requires training to spot equipment malfunctions and to learn improved bag handling practices.
