Worker exposure to ethylene-dibromide (106934) (EDB) was evaluated through industrial hygiene surveys at two manufacturing and two user facilities. Approximately 70 workers in 17 different job classifications were exposed to EDB at these facilities. Air monitoring included 75 personal samples and 22 area samples at different sites routinely entered or occupied by workers. In the manufacturing processes, the median personal EDB exposure for similar jobs was 10 to 500 parts per billion (ppb). In the antiknock blending operations, the exposures were 0.2 to 54ppb. Area samples collected at breathing zone height for various locations indicated median TWA concentrations of 0.2 parts per million (ppm) at processing sites, 0.5ppm at laboratory sites, room sites. Concentrations at quality control sampling sites were car loading and unloading sites. The authors conclude that existing engineering controls at the four facilities were adequate to maintain EDB vapor concentrations below the current federal standard of 20ppm as an 8 hour TWA, but improvements to these control measures would be necessary to meet the NIOSH recommendation of an EDB ceiling limit of 1 milligram per cubic meter or 0.13ppm for a 15 minute period.
