A survey of technology for controlling exposure to dusts during loading of bulk dry materials was conducted at Central Soya (SIC- 2075), Marion, Ohio in December, 1985. Filling open and closed trucks with soybean meal by a loading spout was observed. The control technology consisted of an automated loading spout system equipped with 10 feet of vertical travel, north/south travel, and exhaust ventilation. The system was controlled by a single operator from an enclosed control booth. The enclosed booth reported operator exposure to airborne dust generated during loading operations, especially when open trucks were loaded. The bulk loading building was enclosed on three sides. Gas sensors were used to monitor hexane (110543) in the soybean processing area. Required personal protective gear included safety glasses, hard hats, and safety shoes. Disposable respirators were available. The company had an extensive safety program that included regular safety inspectors, training programs, and annual noise level checks conducted throughout the facility. The author recommends an in depth study of the loading operation.
