Man-made vitreous fibers (MMVFs) are components of a large number of important products manufactured worldwide, and include glass wool, rock and slag wool, and refractory ceramic fibers. These fibers are distinguished from each other by their chemical composition, physical properties and methods of production. Glass wool, or fiber glass as it is more commonly known is a borosilicate compound, produced from molten sand and inorganic materials under highly controlled conditions, Rock and slag wool, sometimes collectively referred to as mineral wool, is comprised of calcium-magnesium-aluminum-silicate glass. Slag wool is produced by melting a mixture of various blast furnace iron ore slags and other raw materials such as clay, sand and limestone in a coke fired cupola. Rock wool is produced using the same process, with a mixture of various natural and synthetic rock sources that yield the desired composition. In both rock and slag wool manufacturing, typically one raw material is the primary component, with other material added to supplement chemical deficiencies. The purpose of this study was to develop a flexible, representative, and valid exposure database for fiber glass and rock and slag wool insulation removal and reinstallation in a cross section of industrial environments with excellent supporting documentation. This information will be used to make more informed decisions to further worker health and safety through recommendation of exposure controls, product modifications, and personal protective equipment use and/or work practice controls.
