Abstract

In this study, occupational exposures to man-made mineral fibers (MMMFs) including glass wool, rock wool, and continuous glass filament fibers were determined and evaluated on the American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Value (TLV). A total of 171 personal samples collected from 4 glass wool fiber, 2 rock wool fibers, 4 continuous filament glass fiber products manufacturing and a glass fiber and rock wool insulations using industries, and determined respirable fibers concentrations using the National Institute for Occupational Safety and Health (NIOSH) Method 7400, "B counting rule. The fiber concentrations of samples from workers installing thermal insulations in a MMMF using industry showed the highest value: geometric mean (GM) = 0.73 f/cc and maximum = 2.9 f/cc, 70% of them were above the TLV, 1 f/cc. Workers' exposure level (GM= 0.032 f/cc) in the rock wool manufacturing industries was significantly higher than those of glass wool (GM=0.012 f/cc) and continuous filament glass fibers (GM=0.010 f/cc) manufacturing industries (p<0.01). No samples were more than the TLV in the MMMF manufacturing industries. There was a significant difference among companies in airborne fiber levels.
