• Description:
  The basic principles of control, substitution, isolation, and ventilation were reviewed as they apply to cutting fluid mists from machining operations. The results of case histories of control techniques used with 17 types of machine tools were provided. These tools included the automatic screw machine, chucker, multi station drill press, multi spindle drill press, gun drill, broaching machine, circular saw, boring, cylindrical center type grinder, surface grinder, plain internal grinder, centerless grinder, gear cutting, hobbing machines, transfer machine, and machine shop general ventilation equipment. The study indicated that the current environmental limit of 5 milligrams mineral oil mist/cubic meter of air can easily be met through the proper use of fluid selection, enclosure, and ventilation. Of primary importance was the selection of the metalworking fluid with the lowest misting characteristics. In instances where straight oils must be used, an anti misting additive can be placed into the cutting oil. A combination of enclosure and local exhaust can be very helpful in controlling mist emissions. A constant supply of clean tempered air will dilute stray mist and provide relief from the heat. Both perylene (198550) and chrysene (218019) were tentatively identified in a bulk sample of a reprocessed straight oil collected during this study. Future research needs in the area of epidemiological and toxicological studies to identify safe levels of these and other polynuclear aromatic hydrocarbons in synthetic metalworking fluids were noted.
