The National Institute for Occupational Safety and Health (NIOSH) is conducting an industrial hygiene survey of 60 small-business machining shops using metalworking fluids (MWFs) to assess the range of worker exposures associated with a variety of existing engineering controls. Shops are being selected for study that represent a range of sizes, machining operations, machine age, fluid types, and engineering controls. Field visits are being conducted between January and October 1997 and last up to 2 days per facility. Full-shift personal and area samples for inhalable and thoracic particulates are being collected and analyzed for the "total mass" and the "MWF mass" concentrations. This paper includes preliminary results only for the personal samples collected during the initial 28 field visits. These results indicated that 92% of all total mass concentrations are below 1.0 mg/cubic m. Differences were observed in the total and MWF mass concentrations by operation type and by fluid type. In general, the highest inhalable particulate mass concentrations (for both the total and MWF mass fractions) were associated with straight fluids. Grinding operations were associated with the highest average total mass concentrations, while turning operations had the highest MWF mass concentrations. For most samples collects, the "MWF mass" contribution was about 50% of the total mass.
