National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Extent-of-Exposure Study: 1,3-Butadiene Monomer Production Industry.

PB87229647

Publication Date	1987
Personal Author	Krishnan, E. R.; Ungers, L. J.; Morelli-Schroth, P. A.; Fajen, J. M.
Page Count	100
Abstract	A new sampling and analytical method developed by NIOSH was used to assess exposure to 1,3-butadiene; the method is not susceptible to interference from four other carbon compounds and has a lower quantitation limit of 0.02 parts per million (ppm). Walk through surveys were conducted at ten 1,3-butadiene monomer production facilities, followed by in/depth surveys at four of the facilities. For all job categories, full shift exposures were below the OSHA permissible exposure limit of 1000ppm. For all job categories, geometric mean full shift exposures were below the threshold limit value of 10ppm; however, some individual exposures for process and laboratory technicians exceeded 10ppm. The authors recommend adoption of several control measures; conversion to closed loop sampling systems; use of dual mechanical seals on pumps; use of magnetic gauges for rail car filling; conducting cylinder voiding using a laboratory hood or vacuum hood; and use of respirators during maintenance on process equipment.
