Abstract
A visit was made to the Micro Switch Division of Honeywell, Freeport, Illinois to investigate the effectiveness of control methods for mercury (7439976). There were 150 workers employed in the mercury switch department. Of the eight rooms involved in this department, the press seal room, the fill room, and the room where adjusting and leading were accomplished were the areas where mercury exposure was most likely. Engineering controls in the mercury fill room included the placement of an air supply and air exhaust system. Personal protective equipment in use at the site included disposable Tyvek smocks which were changed weekly, latex disposable gloves which were changed daily, disposable respirators and shoes used exclusively for work. Work practices were designed to avoid mercury contact. Preemployment and routine ongoing urinalyses were conducted; when mercury levels in the urine exceeded 0.05 milligrams/liter, the worker was taken out of the mercury exposure areas. Mercury was detected in all air samples taken with the highest sample concentration being 0.052mg/m3. The facility is recommended for an in depth survey when a new air supply system is installed and operating. It is recommended that mercury scrap drums be filled only to a point where a 5 or 6 inch level of water can be maintained above the scrap and that the sides of the flat circular hoods be enclosed by plastic curtains.
