Health hazards from oil, soot and metals at a hot forging operation

Abstract

An extensive study of a hot forging operation was performed to characterize and quantitate worker exposures to the aerosol formed by an oil-based die lubricant and it's decomposition products. Total particulate breathing zone levels up to 65 mg/m³ and benzo (a) pyrene levels up to 2.9 µg/m³ were measured.
