Metalworking Fluids (MWF)

Abstract

The present chapter summarizes metalworking fluid (MWF). MWF is the term also used for fluids used in various processes and operation for the manufacture of engines, transmissions, and chassis parts. There are two general categories and four major types of MWF. The characteristics and composition of fluids, as well as technological details of application have been reviewed. The experimental evidence suggests that several agents known to be present in MWF have been classified as carcinogenic. Studies also identified the associations of both straight oil and water-reduced MWF with several respiratory diseases. NIOSH and the OSHA Metalworking Fluids Standards Advisory Committee have reviewed the health hazards and protective measures. Keywords: aerosols; endotoxin; cancer; hypersensitivity pneumonitis; asthma; skin disorders
