-t a E !i 0 RANDOM:- TO: Dr. Wheatley JROM: Mica Reilly PiiTk: June 19, 1944 Attached are copies of the surveys iir.de by Mr. Fehn*>l of the Johnson':Company mines end mills in 1939 and of the new mill in March 1931* The dust con centrations found were much higher than the nlloroble concentration of five million nr.rtlclras per cubic foot as established by the U.S. Public Health Service for dust in asbestos mills. Although there was an improvement in the new mill, the concentration: in the crusher department and the screening department were still, too high. Among six men physically exf-mined two showed first degree asbestos In hut. none of the men appeared to have tuberculosis. The sanitary condition:- in the plant ware rather poor an-' it rr.r notl.e*'1 tlr't t'iere was an unusual degree of carcirssn-sr among the employees In spitting on t,h floor. Housing conditions in Thetford ^Inor. were also poor. Since the oar t.he mlll.r -nd mines have been operating <4 hours a b'-y. The increased work enuring a corr'-'rmr'ding increase in the production of dust, and the lack of reel may produce a deter00 'd resistance among the employees which may Influence the incidence of tuberculosis. If It is advisable Mr. Fehnel c'j:i arrange to go to Thetford Mlu'S to mek a recheck survey of the Johnson's Company properties. If possible, It might be well to include a survey of living conditions of employees.
