Abstract
A walk-through survey was conducted on April 26, 1984, and during the week of April 22 to 26, 1985. Breathing zone samples were analyzed for 2,4 and 2,6 isomers of toluene-diisocyanate (584849) at the Cartex Corporation (SIC-3079) facility near Morrisville, Pennsylvania. Data from this study are to be used in an epidemiologic mortality study of workers exposed to toluene- diisocyanate (TDI). Approximately 150 production workers are employed at the facility, which manufactures TDI derived foam products. Ten of 54 individual personal TDI exposures exceeded the NIOSH recommended maximum time-weighted average concentration of 35 micrograms per cubic meter (ug/m3). The highest exposures were about 55 percent of the the OSHA ceiling limit of 140microg/m3. Exposures were generally greater for pouring line workers than for finishing workers. Air sampling was performed to determine potential exposures to solvents, aliphatic amines, respirable dust, nitroso compounds, and total isocyanates. Worker exposure to total isocyanate groups may be much greater than exposure to the 2,4 or 2,6 isomers. Air samples from within the facility had a greater mutagenic activity in the Ames test than samples collected outside. Recommendations for minimizing the potential for worker exposure are given.
