Worker exposure to 1,3-butadiene was measured at the Denka Chemical Corporation in Houston, Texas. Neoprene and tetrahydrophthalic anhydride were produced at this facility. Workers full-shift exposures to 1,3-butadiene were below the American Conference of Governmental Industrial Hygienists Threshold Limit Value of 10 parts per million (ppm) and the Occupational Safety and Health Administration Permissible Exposure Limit of 1000 ppm. The arithmetic mean, full-shift exposures for all job categories were less than 1.43 ppm. The authors recommend that the general-dilution ventilation conditions in the quality-control lab be reassessed in order to control exposures to the head shift testers conducting analysis on 1,3-butadiene samples. Replacement of the threaded fittings on the bombs with other fittings should be considered, thus reducing any possible releases of 1,3-butadiene when making closed loop connections to obtain quality-control samples.
