Abstract
A survey was conducted to assess techniques to control occupational exposure to mercury (7439976) (Hg) at the Duracell USA (SIC-3691) facility in Lexington, North Carolina in June 1982. Engineering controls and work practices were found to be effective in maintaining Hg vapor concentrations generally below the OSHA standard of 0.1 milligrams per cubic meter. The facility used a ventilation/recirculation system designed to remove both Hg vapor and particulates. The system was found to be functioning at an efficiency of 73 to 85 percent while also reducing energy consumption. The work practices included a very strict personal hygiene program. The author concludes that the ventilation/recirculation system is an effective way of controlling exposure to Hg vapor. It is recommended that a periodic monitoring program be set up to ensure optimal performance of the system, as malfunctioning of the system could cause high Hg concentrations. The program should include monitoring filter efficiency, determining air flow characteristics, and determining the quality of the recirculated air. Other large scale industrial operations that use Hg should consider such a system.
