A walkthrough industrial hygiene survey of the Dow Chemical Compay Allyn's Point styrene butadiene (SB) latex-producing facility in Gales Ferry, Connecticut, was performed. Bulk polymer samples were analyzed for free-monomer emanation at ambient, highest polymer process, and highest estimated end use temperatures. Quality-control testing included purity and dimer content of incoming 1,3-butadiene and residual 1,3-butadiene content of the latex. Of 164 workers, 20 production and 13 administrative personnel worked in the SB area where 1,3-butadiene was used. Personal monitoring conducted from 1975 to 1985 showed the mean 8-hour time-weighted average exposure was 0.25 parts per million (ppm). Area monitoring showed the highest concentration, 0.56 ppm, in a reactor and a stripper area. SB latex at ambient, process, and end-use temperatures showed free monomer to be below the 0.04 nanograms per milligram limit of detection. The authors conclude that this production facility is a candidate for inclusion in an in-depth exposure survey regarding 1.3-butadiene.
