Oil mist and oil smoke arise from a variety of high speed manufacturing operations such as milling, turning, boring, grinding, etc. As these operations are carried out, fluids are emitted in the form of aerosols and smoke.
 

Oil mist is hazardous to your health. The National Board of Occupational Safety and Health has specific limit values for the emission of aerosols to industrial premises. Other associated hazards are slippery floors and oily equipment.
