The Manville Products Corporation (SIC-3295) in Lompoc, California, was surveyed on August 6, 1982 to determine its suitability for an indepth study of engineering control technologies. Specifically, the packaging operation which bagged diatomaceous earth products was studied. A total of 375 hourly and 95 salaried employees worked at the facility. Observations included engineering controls, work practices, and personal protective equipment. Exhaust ventilation was provided at each manual bag filling station. There was a capture hood around each packer spout and a hood with exhaust ventilation around each packer unit. Inside and near the top of each press well, there were slots for exhaust ventilation designed to capture airborne dust generated during pallet loading. Air washers under exhaust ventilation hoods were used to remove surface dust from filled bags. An automatic packaging system had recently been installed to further reduce human exposure to dust. Personal protective equipment included safety shoes, glasses, hard hats, and respirators. The authors conclude that the ventilation system at the packer station, automatic packaging system, and continued efforts to improve engineering controls represent exemplary controls worthy of further study.
