Abstract
Health hazard control methods, work processes, and existing control technologies used in the manual transfer of chemical powders were evaluated at Corning Glassworks (SIC-3851), Harrodsburg, Kentucky in May, 1984. The company employed 300 workers involved in the manufacture of ophthalmic glass lenses and glass sheets. The main dry ingredients were silica (14808607), lead (7439921), zinc (7440666), nickel (7440020), copper (7440508), arsenic (7440382), and fluorides. These raw materials were dumped into a hopper and mixed with sand, and the filled hopper was mechanically transported by crane to a batch mixer. The materials were released into the mixer, and the mixed batch was dispensed into containers for processing or storage. Local and general exhaust ventilation was used. Workers received job training on good work practices and were given health and safety education materials. All employees received preemployment physicals, and selected employees underwent annual physicals, blood lead sampling, and chest X-rays. Periodic dust sampling was performed. Safety glasses, ear plugs, and respirators were provided. The author does not recommend an in depth study of the control technologies at this company since no unique state of the art methods are used.
