Evaluation of Paul Bergsoe and Son Secondary Lead Smelter.

NIOSH 1979 Jan; :1-113
New technology in secondary lead (7439921) smelting, particularly in the special battery smelting and flue dust flash agglomeration processes was evaluated at the Paul Bergsoe and Son secondary lead smelter in Glostrup, Denmark in September, 1978. The smelter's feed materials consisted of approximately 12.6 percent polypropylene (9003070) case and 12.6 percent hard rubber case whole batteries. The remaining feed materials were crushed battery plates, and lead scrap. The average production rate during the test period was 70.5 metric tons of lead per day. Air sampling of controlled stack emissions indicated the following concentrations: 0.046 to 0.056 kilogram per hour (kg/hr) of lead, 0.52 to 0.54kg/hr of antimony (7440360), 0.0005 to 0.0013kg/hr of arsenic (7440382), 1.6 to 7.1kg/hr of chlorine (7782505), and 6.9 to 9.1kg/hr of sulfur (7704349). The authors conclude that employee exposures to lead are maintained below 100 micrograms per cubic meter at this smelter by high quality engineering and work practice controls, yard sprinkling, washdown procedures, and good general housekeeping efforts.
