Abstract
An in depth survey was conducted at the Amoco Chemical Company (SIC- 2869), Alvin, Texas in March, 1985. Environmental and breathing zone samples were analyzed for 1,3-butadiene (106990). Company air monitoring data for 1,3-butadiene was reviewed. Engineering controls were investigated. Breathing zone 1,3-butadiene concentrations ranged from less than 0.02 to 0.66 part per million (ppm). The OSHA standard for 1,3-butadiene is 1,000ppm. Environmental 1,3-butadiene concentrations ranged from less than circulation pump. Company data showed 1,3-butadiene exposures ranging from less than 0.02 to 2ppm. Engineering controls included single mechanical seals on all pumps in the 1,3-butadiene recovery area, using closed loop bombs or on line gas chromatographs for quality control sampling, local exhaust ventilation in the quality control laboratory, and monitoring loading of 1,3-butadiene into rail tank cars by slip/tube and magnetic gauges. The authors conclude that the survey exposure data agrees with the company air monitoring data. The current exposure controls maintain exposures to 1,3-butadiene at a few ppm. Recommendations include replacing existing single seal pumps with tandem seals and using only magnetic gauges for monitoring loading of rail tank cars.
