White21 University of New Haven, New Haven, Connecticut2 Milacron Marketing Company, Cincinnati, OhioNIOSH published a recommended Exposure limit (REL)for Metalworking fluids (MWF) in 1998 that was designed toprevent respiratory disorders associated with these industriallubricants. The REL of mg/m3(as a time-weighted averagefor up to 10 hours) was for the fraction of aerosol correspond-ing to deposition in the thoracic region of the lungs. This non-regulatory Occupational Exposure limit (OEL) corresponded toapproximately mg/m3for total particulate mass. Althoughthis REL was designed to prevent respiratory disorders fromMWF exposures, NIOSH acknowledged that exposures belowthe REL may still result in Occupational asthma and hypersen-sitivity pneumonitis two of the most significant respiratoryillnesses associated with MWF.
