A walk through survey was conducted at EI du Pont de Nemours and Company (SIC-2822), LaPlace, Louisiana in August, 1985. The purpose of the survey was to obtain information on the neoprene polymer production process and to evaluate the potential for exposure to 1,3- butadiene (106990). Bulk samples of neoprene were analyzed for residual 1,3-butadiene. The facility produced hydrogen-chloride and chloroprene as marketable products as well as neoprene. The process occurred in a closed system, tightly maintained for economic and fire hazard reasons. Single mechanical seals were used on all 1,3- butadiene pumps. Quality control sampling was done using gas bags in the tank farm. No residual 1,3-butadiene was found in the bulk neoprene samples. The company reported they had conducted air monitoring for 1,3-butadiene and found most exposures to be below 10 parts per million. Personnel records on current and terminated employees were maintained. A total of 1,264 workers had worked at the facility. The authors conclude that the facility should be considered a candidate for an in depth survey. The company should consider retrofitting dual mechanical seals on all process pumps with single mechanical seals.
