Metal working fluidis widely used as coolant, lubricant and rust remover in mechanical processing. Oil mist will be formed in the process of metal working fluid. The composition of oil mist is complex, which can produce many adverse effects on the environment and operators. This paper reviews the health hazards of metal working fluid oil mist on human skin, respiratory system, teratogenic and carcinogenic aspects, and discusses the establishment of occupational exposure limits in workplaces of oil mist in foreign countries, in order to provide reference for the prevention and control of occupational health risks of metal working fluid oil mist and the establishment of occupational exposure limits of oil mist in workplaces in China.
