Health hazard control methods, work processes, and existing control technologies used in the manual transfer of chemical powders were evaluated at North American Philips Lighting Corporation (SIC-3641), Danville, Kentucky in May, 1984. The company employed about 400 workers involved in the manufacture of light bulbs and tubes. The main ingredients used in batching of dry materials were silica (14808607) and lead (7439921). The raw materials were processed through an enclosed, automated mixing procedure to produce the requisite composition, then automatically transferred to the melting tank. The molten glass was transported through different forming processes to produce the finished product which was subsequently delivered to the warehouse for distribution. General exhaust ventilation was provided, and workers were furnished with safety glasses, respirators, hearing protectors, and protective clothing. All employees received preemployment physicals, and those in the batch mixing department received annual physicals that included hearing tests, chest X-rays, and blood and urine lead determinations. Workers received health and safety training. The author does not recommend an in depth study of control technologies at this company since no unique control methods are used.
