Health Effects from Occupational Exposure to Metalworking Fluid Mist

Abstract

Metalworking fluids (MWFs) are an essential part of a technological process. They are used in machining operations for enhancing cutting process performance. The performance of MWFs depends on properties such as specific heat, viscosity, density and thermal conductivity. MWFs are used to cool and lubricate the cutting zone, flush away chips and inhibit corrosion during machining operations. On the other hand, MWFs are associated with formation of liquid aerosols (mists) that represents two types of occupational risk factors for machine operators - chemical and biological. Epidemiological assessments with machine operators in the metalworking industry have identified dermatologic and respiratory effects. The aim of this article is to review what is known about health effects from inhalation exposure to mist from various types of MWFs.
