Mercury Control Technology Assessment Study: General Electric Company, Circleville Lamp Plant, Circleville, Ohio. Preliminary Survey Report for the Site Visit of October 6, 1981

摘要

A visit was made to the General Electric Company's Circleville Lamp Facility, Circleville, Ohio for the purpose of evaluating control methods designed to protect the workers from exposure to hazardous levels of mercury (7439976). The visit included a review of the fluorescent lamp manufacturing process, a tour of the production facility, and an investigation of engineering controls, work practices and monitoring programs. Existing control strategies appeared effective in maintaining mercury vapor levels below the OSHA standard of 0.10mg/m3. This was achieved through a combined effort in providing extensive dilution ventilation, modifying process equipment for mercury control, and developing the proper work practices for handling mercury. Areas suggested for further research as a result of this visit include the development of a small portable vacuum cleaner which would be effective in safely cleaning mercury spills, developing a procedure to reprocess mercury laden oil, and developing a comfortable and light weight powered air purifying helmet for respiratory protection against exposure to mercury vapor.
