Abstract
Air sampling and employee medical evaluations were performed on April 4 to 7 and May 4, 1978 to determine exposures to a new urethane catalyst compound consisting of 95 percent 3- dimethylaminopropionitrile (1738256), and 5 percent bis- (2(dimethylamino)ethyl)ether (3033623) used at Lear Siegler, Inc., (SIC-2531) in Marblehead, Massachusetts. The evaluation was requested by an authorized employer representative to determine exposures of 231 affected workers. Qualitative ventilation measurements were made by using a hot wire anemometer and smoke tubes. Quantitative measurements for airborne organic vapor contaminants were taken with an organic vapor analyzer, swipe samples were obtained and relative humidity and temperature measurements were made with a psychrometer. Qualitative and quantitative assessment of exposures to airborne organic vapor were obtained using calibrated battery operated personal monitoring pumps in combination with liquid and solid adsorbents and filter cassettes. Results of environmental sampling revealed that acetone (67641), aliphatic hydrocarbons (C9-C11), bis- (2(dimethylamino)ethyl)ether (3033623) (A-99), dimethylaminopropionitrile (1738256) (DMAPN), methylene-chloride (75092), trichloroethane (71556), trichloromethane (67663), trichloroethylene (79016), triethylene-diamine (280579) (TEDA), toluene-diisocyanate (26471625) (TDI), styrene (100425), quartz (14808607), and wax particulates were present in the work environment. TDI and C9-C11 exposures were toxic. The authors conclude that a health hazard exists at this company and they recommend ventilation improvements and health safety programs to ensure worker health and safety.
