Ten companies have an AOL program already. B. F. Goodrich has long been the leader in doing extensive employe analysis to detect AOL early. Europe has recently reported many cases of AOL in PVC plant employes. Originally thought to be caused by hand reactor cleaning, cases in lead operators and other non-cleaners now proves that aUl is caused py repeated exposure to low concentrations or vcm (50 ppm;. Bulk Truck Loading ' ^ Four companies use life lines on operators while loading and climbing on bulk trucks. Several companies expressed concern at the high injury potential of this operation. d. Fisheye Control > t Pantosot* indicated that maintaining the oxygen level in " the vapor space above incoming vcm tame cars helow lod~5pm would nave a greet effect on reducing fisheyes. Airco, Pantasot* and Diamond Shamrock confirmed that once tha oxygen level in the RVCM system was monitored and controlled to prevent polyperoxide formation, fisheves improved considerably. a. New Solution Fast Catalysts Reference was mad* during the catalyst handling and storage discussions, that not only do the solution catalysts reduce the severe hazard of handling solid IPP, but give better conversion and cycles as well. No indication of which fast catalyst was made, however. f. Shortstop Testing Uniroyal is doing some testing to determine the effectiveness of isoprene in various concentrations and under different conditions as an emergency shortstop. Isoprene was reported at an earlier meeting to be the most effective shortstop for PVC reactions. Uniroyal will make the test results available to the Vinyl Chloride Safety Association in unpublished form at a future meeting. RSV 0000102 to C. o o BFG62204 VINYL CHLORIDE SAFI .
