Since your plant currently has an ongoing monitor ing program to determine employee exposure to vinyl chloride non mer, the results of this report are obviously less meaningful than the more recent surveys conducted by your personnel* The results reported during the surveys of April through June, 1974 are in question. This is due to the fact that the method us a vinyl chloride vapors in the air was less than relia It was also found during fcheijCSNC he styrene and butadiene levels found ak. 1 ring area were well below the threshol<M^slt^values of these chemicals* They make no recommendations that need attention* At best, this report serves as a documentation of conditions during the sample periods.
