Abstract
A walk through survey was performed in February of 1984 at E. R. Carpenter Inc. (SIC-2221, SIC-3079), a producer of flexible foam slab in Richmond, Virginia. Due to its size, completeness of personnel records, and long term use of toluene-diisocyanate (TDI) (584849), this company was included in a retrospective mortality study on TDI exposed workers in the polyurethane manufacturing industry. Personal sampling for TDI was carried out in May, 1985. Exposure to TDI was primarily limited to pouring line workers. Time weighted average (TWA) exposures were all less than half the current Federal peak exposure limit. Finishing workers had exposure to prepolymeric isocyanate containing compounds, often in excess of the comparable TDI concentration exposure limits. Seven personal respirable dust samples were collected from workers with the greatest potential exposure to polyurethane dust. All indicated low exposures, below 0.5 milligrams/cubic meter, not expected to present a hazard. Aliphatic amines were not detected in the general workroom air. Airborne mutagenic substances, present as particulates, were found. Chronic low level exposures to methylene- chloride (75092) and other solvents occurred among finishing workers, especially where glues were used. The authors recommend that a distributed fresh air system be installed that would replace 90 to 100 percent of the exhaust air.
