Industrial Hygiene Walk-Through Survey Report Of Synpol Inc., Port Neches, Texas, Report No. IWS-147-29.
NIOSH 1986 Feb:21 pages
A walk through survey at Synpol, Incorporated (SIC-2822), Port Neches, Texas in August, 1985 was conducted. The purpose of the survey was to determine the feasibility of including the facility in an in/depth survey of 1,3-butadiene (106990) exposure. Bulk samples of styrene-butadiene (9003558) rubber (SBR) and emulsion butadiene rubber (EBR) were analyzed for residual 1,3-butadiene. The facility produced SBR and EBR by hot and cold polymerization. Personnel records were maintained permanently on current and terminated employees. The personnel file contained approximately 1,325 records dating back to 1950. Personal monitoring for 1,3-butadiene had been conducted since April, 1976. Only 8.7 percent of the samples exceeded 10 parts per million (ppm), the threshold limit recommended by the American Conference of Governmental Industrial Hygienists for 1,3-butadiene. Stripping column operators appeared to be the group with highest exposure; 32 percent of the samples exceeded 10ppm. None of the bulk samples contained detectable 1,3-butadiene residues. Engineering controls included in/line meters on delivery pipelines, closed loop bombs for quality control sampling, and once through air ventilation in the laboratory. The authors conclude that the facility qualifies for further consideration as a candidate for site selection for an in/depth industrial hygiene survey.
