^% ^L CHEMICALS 01 ------------------ INDUSTRIES TO J. M. Davis FROM Dr. H. B. Lovej oy ftEO'D QCT211S2& INTEROFFICE / LAKE CHARLES DATE October 9, 1975 SUBJECT Approval for Vinyl In accordance with our conversation this morning, I am advising you in writing that I feel that personnel who have had abnormal liver function tests and have had follow-up liver tests which have become normal in three or more months may return to work in the vinyl or organics area. These people however should be rechecked in another three months by the same liver tests and again in six more months and if any of thesg) are abnormal they should be permanently removed from this area, xf they remain normal they resume their annual blood and physical examination schedule. It is my feeling that the^vast majority of abnormal liver function tests are caused by regular and rather heaVydrinking of alcohol and I expect that the people who have abnormal liver testes a result of this may be inclined to resume their previous habits as soon as they reel they are okay, and this is my reasoning for the above scheduling.
