Abstract
Studies on handling mineral wool within the Swedish construction industry were summarized. The results of previous studies had indicated that airborne respirable fiber concentrations generated during mineral wool handling were relatively low compared to the Swedish standard of 1 fiber per milliliter. However symptoms of skin irritation still occurred when mineral wool products were handled. These were attributed to coarse fibers being released. The current studies were part of a project that investigated techniques for handling mineral wool that minimized emission of coarse fibers and which developed new methods for quantitating fiber concentrations. The handling studies have indicated that manual handling was considerably reduced when mineral wool products were delivered in crates or on pallets. It was noted that large quantities of dust were stirred up during cleanup and collection of mineral wool waste, however this problem could be minimized by providing special containers for collecting the waste. A new method, under development, for measuring mineral wool fiber concentrations that involved vacuuming up fiber dust immediately after insulation work has been completed was described. Preliminary evaluations revealed that fibers having diameters of around 50 millimeters can be collected in this manner. Studies on documenting the behavior of airborne fibers using video cameras have also been conducted. The author states that these may ultimately be of use in assessing fiber emissions during insulation work.
