A visit was made to the Frit Bagging Operation at the Chi-Vit Corporation (SIC-3229) located at Urbana, Ohio for the purpose of examining methods used at this facility to control worker exposure to hazardous materials during the production of various frits. Frit was the basic material for porcelain enamel used in major appliance finishes. The three major raw materials used to product frit were soda-ash (497198), borax (12447404), and silica-flour (14808607). In the manufacturing area batching, mixing, smelting, and bagging take place. All new employees were given a preemployment physical. An annual hearing evaluation was performed for all workers. Ventilation was provided throughout the operation. Each weight bin in the batching area was equipped with exhaust ventilation. The frit was moved by a vibration conveyor between smelter and bagger and passed under three exhaust hoods to remove airborne dust during this last portion of this transfer. A small capture hood at the packer unit removed airborne dust generated as material falls from the slide gate to the packer spout. The disposal of the bags was carried out in a very satisfactory manner. The author concludes that that the controls used provided an exemplary work environment. The author recommend that an in depth survey be conducted at this site.
