The objectives of this study were both to discuss the sampling method for airborne metalworking fluids(MWF)´ mist and to suggest measures to minimize worker´s exposure to carcinogen contained in metalworking fluids. In order to measure airborne MWF mist, it seems to be appropriate to use NIOSH Method #0500(filter weight) rather than NIOSH Method # 5026(analysis by FTIR). Because MWF mist on PVC filter evaporated and migrated during sampling worker´s exposure to MWF could be underestimated. So, when evaluating worker´s exposure to MWF mist, other environmental conditions also must be considered. Enclosure and local exhaust ventilation system seems to be the most effective measure and must he constructed with process facility. In order to control worker exposure to carcinogens contained in MWF, distillation type and condition for crude oil, PAH concentration in MWF, and viscosity index of MWF must legally he described.
