Williamson Gentlemen: Subject: Vinyl Chloride Monitoring Cooperative Sampling at Glidden-Alant* On August 22 Jack Long and the writer visited the Glidden-Atlanta facility and did some cooperative vinyl chloride monitoring with Bob Lake of Glidden. We received a tour of the plant and indicated we would be glad to help out with such monitoring in the future. , Our samples were collected over 5 to 15 min. intervals on activated char coal at flow rates of 120 cc/roin., desorbed with carbon disulfide, and analyzed by gas chromatography. Bob1 collected his samples on activated charcoal at flow rates of 1% liters/ .min. (which seemed rather high to me) and sent the samples to their R fit D Dept, in Cleveland for determination of vinyl chloride and certain specific ketones. He did not know anything about their analytical methods but said all of the vinyl chloride numbers received thus far were very low. t Out monitoring showed concentrations ranging from 0.3 to 1.1 ppm, the higher concentration being in the PVC cuttine platform area where PVC was being dissolved in toluene at about 60C. Toluene odor in this area was rather strong. A sample collected from the head space of Glidden's storage tank for our U-1000 showed 0.66 ppm VC1, however, the tank was nearly empty and the concentration would be expected to be low. Another sample collected from the head space of a tank containing 4500 gal. of paint made from U-1000 late showed 0.34 ppm VC1. This tank was nearly full. ucc rn?7fi4 the results of our monitoring are shown on the attached page. Our numbers indicate they have no serious vinyl chloride exposure problem, particularly with regard to our latex. Workers spend only a limited amount of time on the vinyl cutting platform so the 1.1 ppm VC1 level in that area does not reflect their exposure over an 8-hour period. We have communicated these results to Glidden and are awaiting feedback from their laboratories. John L.
