Abstract
The control technology available to minimize worker exposure to toxic chemical and harmful physical agents used or generated by the secondary nonferrous smelting industry was evaluated. Information provided by OSHA, NIOSH, state agencies, and other sources, as well as 22 preliminary and 12 indepth surveys of secondary smelters was reviewed. Engineering and administrative controls, and personal protective equipment were identified as the major methods for protecting workers from specific hazards. The control technologies that could be applied to other smelters included supplied air islands to control exposures during rotary furnace tapping in the presence of high background metal fume contamination, enclosure of point noise sources, slotted ladle hoods to distribute evenly the capture zone around the perimeter of the ladle, flue dust agglomeration to reduce exposure from loose dust, and isolated or enclosed change preparation to reduce exposure from raw materials during change preparation. The authors conclude that all of the secondary smelters visited during this evaluation had weaknesses in their industrial hygiene and safety programs. They recommend additional research and development programs to improve control technology in the secondary nonferrous smelting industry.
