Vaporization and Conversion of Ethanolamines used in Metalworking Operations
OBJECTIVES This study examined how ethanolamines (EAs) with the same functional alcohol group (HOCH(2)CH(2)), such as mono-EA (MEA), di-EA (DEA), and tri-EA (TEA), in water-based metalworking fluids (wbMWFs) are vaporized, condensed, and transformed by heat generated during metalworking. METHODS Two types of experimental apparatus were manufactured to achieve these objectives. RESULTS Vapor...
متن کاملMetalworking fluids: oil mist and beyond.
This article is based upon my own experiences with metalworking fluids and the adverse health effects and medical conditions associated with exposure to metalworking fluids. I have researched and witnessed the benefits that can be achieved when metalworking fluids are properly maintained and managed.

متن کاملThe Occupational Exposure Limit for Fluid Aerosol Generated in Metalworking Operations: Limitations and Recommendations
The aim of this review was to assess current knowledge related to the occupational exposure limit (OEL) for fluid aerosols including either mineral or chemical oil that are generated in metalworking operations, and to discuss whether their OEL can be appropriately used to prevent several health risks that may vary among metalworking fluid (MWF) types. The OEL (time-weighted average; 5 mg/m(3), ...
متن کاملSocial disparities in heart disease risk and survivor bias among autoworkers: an examination based on survival models and g-estimation
OBJECTIVES To examine gender and racial disparities in ischaemic heart disease (IHD) mortality related to metalworking fluid exposures and in the healthy worker survivor effect. METHODS A cohort of white and black men and women autoworkers in the USA was followed from 1941 to 1995 with quantitative exposure to respirable particulate matter from water-based metalworking fluids. Separate analys...
متن کاملApplication of vegetable oil-based metalworking fluids in machining ferrous metals—A review
The increasing attention to the environmental and health impacts of industrial activities by governmental regulations and by the growing awareness level in the society is forcing industrialists to reduce the use of mineral oil-based metalworking fluids as cutting fluid. Cutting fluids have been used extensively in metal cutting operations for the last 200 years. In the beginning, cutting fluids...
