A walk through survey was conducted at GNB Batteries (SIC-3069) in Saint Paul, Minnesota, on August 23, 1983. The survey was conducted as part of a study of dust control during bag opening, dumping, and disposal. The facility employed six persons and was built in 1971. The operation of the automatic bag opener in use at the facility was observed. The device was installed to open bags of carbon-black (1333864) and barium-sulfate (7727437). Potential hazards included: exposure to numerous dust emission sources from dust on the outside of bags; bag handling, opening, emptying, and disposal; and equipment malfunction. The author concludes that the automatic bag opener generally controlled the dust generated by bag opening, emptying, and disposal. Worker exposures to dust are increased when bags do not come off the conveyor and have to be removed by hand. A study of a modified automatic bag opener is recommended.
