Oil mist and oil smoke arise from a variety of high speed manufacturing operations such as grinding, milling, turning, boring, etc. As these operations are carried out, fluids are emitted in the form of aerosols and smoke in the range of 1µ to 10µ. The amount of oil mist in air is measured in mg/m3, and The Occupational Health and Safety Administration has set a threshold limit for what is allowed in a manufacturing facility.
