LINCOLN VICE PRESIDENT AND GENERAL COUNSEL. February 27, 1955 ryy/ '/U Yesterday I suggested that Dr. Lanza and I would like to go over our current activities and certain recent developments In the field of dust in industry, in a conversation with you, so that all angles of the situation could be considered in connection with our routine activities and special appropriations. Dr. Lanza has endeavored to summarize his views in the attached memorandum, and it occurs to me,' if you have time, that ` it will he helpful to look this over prior to our conference. Tie could then no douht. get the benefit of your reactions in a very few minutes, and can perhaps present certain angles of the situation more compactly In this memorandum than could be done in conversation. ' v * .'"'Wfv ' u.i -> A. . .. I suggested a reply to General Cunning* s letter concern ing the silicosis researchjiith'the Public Health Service that in- dicated the belief^thatTour participation in this particular activity should be terminated, unless' theTparticipation of other agencies' ' might later seen to justif^our continuation on a modified basis. . 'The.field is really of`great importance, and a little stake in the ' research aspect of. itjTiointl'with the leading' Government^agency in the field, say actually be'quite'advantageous and logical in view of the significance of the'dust`problem to. our extensive Group and _ Industrial interests and in view of the'routine services now carried" ' out by. the Industrial Health Section primarily for Group policyholders end largely in this dust field, as indicated by Dr. Lanza*s memorandum 'S' D. B. Armstrong, M.D. Third Vice-President. /> DR. APWSTHOJG THIRD VICE PRE5ID13JT With reference to our recent conver3atirn, I will endeavor to summarize the present status of the dust question in industry and our re lation to it. Viewed broadly, the problea of du3t in industry is the problem of tuberculosis in industry. Conversely, it may be stated that the problem of tuberculosis in this country today ia an industrial one. It is true that the' death rate iron tuberculosis ia general has been steadily falling for a num -*>; ber of years. It ia also true that the vital statistics in this country and abroad show definitely an inordinate amount of tuberculosis in what might bo summarized as the dusty trades. * * T . , The specific action of silica dust is well known as is the fact that' y * those exposed to silica dust have an extremely high tuberculosis doath rate. ^ Xn the last few years, there has been an extraordinary number of damage suits* brought by employees against employers on the basis of exposure to silica duat^ so that at the present time it is estimated that these damage suits are wells? in excess of $100,000,000. How there is a very marked tendency of employees"5^ who are expfefled to dust other than silica dust to bring damage suits against ' their employers, alleging pulmonary injury and this state of affairs has pro- t * greased to a point where whole industries are in a turmoil, handicapped on the"" one hand by lack of definite knowledge of the action of these dusts on the lungs'^ and on the other by the inadequacy of the law to protect them. The Metropolitan has jhad a co-operative agreement with the Public Health Service {formerly with'th Bureau ,of,Hines} to c a n y on dust studies. As the budget was originally set up for. the 'Richer Clinic, the mine operators^ (Group policyholders) contributed $15,000 a year, the Government $8,000 a yag^j and the Metropolitan $8,000 a year. Later when th Picher Clinic was turned 3? over to the operators, our relationship with the Public Health Service continue! Both we and the Public Health Service contribute $8,OCO a year' for co-operative dust studies. ....: ~ ' -- --- - - iwSn TTe have also contributed $5,000 a year for several years to the Saranac Laboratory for the Study of Tuberculosis for studies ca the pathologies effects of dusts. Last year, this office was instrumental in getting both the Association of Stock Casualty Ccmapnies and the Association of Mutual Casualty Companies each to contribute $5,C00 a year. The object of these studies, particularly at Saranao, has been to increase our knowledge of the action of silica dust in the body, its relationship to tuberculosis, end the determining of method of prevention and control of the silica dust hazard. With respect to the Public Health Service, we have beor^ more concerned with formulating accurate and apoBdy methods of determining nhethjj any given dust is harmful and as a matter of fact, such a technique has been ^ Hr. .:na.t<trnn' - 2 S 'tf -c.-.pstor.e, carborundum, anthracite foundry dust, fullers arth, +ion, hut all representing dust,- policyholders. ?

" jr ' jhorTicl m A M r * Hitchins spent an aftoroon with me, 6ut^! lining their piano and endeavoring to formulate their procedure. It wao madn n `" A feotly plain to "wj1 inw.il .'JMppjWBW _w jr. vrr.'.stiong - 5 represent are looking to tho Metropolitan for advice and leodershi- in 'i,is c:.- ; denvor to set up a co-ordinating agency to deal rith dust prohierre. M- Hi - tola te that he had received c letter Tree Mr. Genthcltz, Counsel Tor the Republic Pteel Company, stuting that his Compapy- would not be interested in uMs -Hts'urr'- plan uniess I wore associated with it; also that he had received a lettei \o Lai- ' 1-r effect from Mr. E. 0. Jones cn behalf of the National Founders rsfociatir.n. I tela Mr. Kitchins and Mr. Sherwood that 1 would be glad to be of any x-sstole * help in the way of advice and consultation but that I could not r.teresc v-s.::' 1 in tills undertaking in any more active rrsy. ,, Naturally, it io our large Group policyholders who have the meat vital v interest in this whole dust problem, such as the Geneial Electric Company, the Westingheusa Electric Company, Jones and Laughlin, Pickcns-Mathor, General Motors,' " Cleveland Cliffs Iron Company, Union Carbide and Carbon Corporation, the gypsun and cement companies. Since this meeting, I have teen consulted by representatives * of both the Republic Steel.Company and the American Car and Foundry Company, both-'tl incidentally, very active prospects for Group insurance. Yo . ./.>v Appended to this'memorandum is a list of the various parsons who partici-v pated in the Mellon Xnstitute^meeting I mention all this to shew how wide--spread*^** and active is the interest of these large manufacturing companies, cany of rhem are | numbered among our Group policyholders. ^ In a paper presented before the National Tuberculosis Association two years ago,-Lanza and Vane estimated on a conservative basis that there were ever half a. million Industrial workers exposed to silica dust and that the problem of family infection due to incident tuberculosis in many instances is a serious cne7'r"T . I do not know whether this, effort to set up a co-ordinating agency to^'^h deal with dust problems in industry will be successful or not. I am inclined to* -"'* think that there are possibly too many divergent interests represented in tho group that was brought together at Pittsburgh to get concerted action from them. But there Is no .question in my mind that many of the largest industries in the *.* "Y Country are looking to the Metropolitan as the one place where they can get accur-.-X ate and Impersonal guidance in dealing with the problem that at present is a serious menace to them from an economic standpoint. This io true also of the casualty in- / surnnee companies with whose representatives both Dr. McConnell and I have had many ~ conferences in the past two years. i As you well know, we have been extremely careful to keep away from nil h litigative and legislative matters and there is a pretty general realization now * in industry that wa cannot be approached on these two phases of the subject. The *, effect of this has been, I think, to strengthen our position; thero is a general * feeling that we have no ax to grind and that our motives are in accord with cur general policy of being willing to help as far as practicable, in any undertaking'-^! that has to do with the conservation of human life. I-/ -.'`IV* ^ vn-t_ .v I'r. an..strong - 4 r respect to our relationship with the Public Health Service I can quite understand that it may not be expedient to continue further oii present relationship. I do think that we should have sone interest <n re- nearch rork in .the geneml field of dust diseases. . . February 27, 1935 .
