The non vho take dust samples for Mrc Mitchell took simultaneous samples vhilo Mr. lumsden vas working so as to double check the counts and procedures. ' Description of Medical Program Dr. Seay visits the plant a certain number of hours each week examining now employees and he has started examining the older employees and hope3 to give everybody an examination within the next year or two. Apparently the men,are scheduled either by-length of service or alpliabstically--so far they have -examined down to letter J Mr. Mitchell said there had been no new Asbestosis case3 since 194-8? but according-to our files there are at least four (4) nov cases up to be tween 1954 and 194-8 o _ The nurse was interested in eye testing machines and wished my opinion. They use only the Snellen eye chart. It was reccmmsuded that a sisall Jaeger could be obtained. Mr. Mitchell stated that his insurance carrier at one time thought of doing a noise survey but apparently did not think that the decibel level was high enough end it had not been done. I offered to do this if he so desired. I mentioned to him the experimental work done by Dr. Arthur Vorwald several years ago concerning the harmfulness of the longer fibers of asbestoso Kr. Mitchell'vas aware that Johns-Mhnvillo Go. was counting both the long-and short fibers and he intended to speak with them to see what their results wore. It was recommended to him that he also develops some information about the long fibers (those greater than 10 micron). He discussed several new vontilati prejects to Mr. Lumsdcn and it is thought that this would further reduce their dust counts. He has recently installed a floor cleaning project, The floors are sanded down and give the impression of much greater cleanliness, He is doing this for the psychological effect. Ho plans to put into operation somo new 11 opening13 machines which will be completely enclosed and he also int.ends to recirculate air from his Vheelabrator. It's interesting to -row that he. had a dermatitis problem from fiberglass which was not cleared up until proper engineering controls were applied. He also stated that all tho engines ax; controls wore justified to managensnt on a dollars and cents basis. M, D. 3 PIA1NTIFPS | EXHIBIT
