The resaarch proposal received from Saranac Laboratory per tairir.Ti to the relationship of pulmonary cancer to asoestosis was reviewed in detail* There is increasing publicity both in the professional arc popular literature concerning the relationship of asbestosis to cancer, Several articles tying the two together were cited by the ccnrittae, For eicar.pl, in tha.Cor.sur.srs1 Reports, a popular publication of national distribution, one of the ureter ccr.parios report=d that they currently have a vrorkr.er.1 s ccr.per.cacior. caco claiming that pulmonary cancer van caused by aiccooure to acbestosic. It ic obvious iron the Saranac proposal that research into this field is exceedingly complex; tiiat the techniques are difficult; and that a considerable length of tine and a large number of (ucperinental animals are required, ^he Saranac proposal covered a three year period. It v:as the consensus of the committes* that an additional proposal be obtained iron another research agency and reviewed before making a definite rccorr-.er.daticn to the Board of Governors, It vas also suggested that when our tuiriin" be carve crystallised, other asbestos industries, such as the -asbestos canant, tie insulation and asphalt -v n V.o ^-^^-1--1"*. 2 i *o ccccjCiics *-n "r*- 1*13 of the research 2, called that in Dr, Schemers5 visit to the ccrrittae, mention had been nas-s of the carcinogenic properties of car vain oils and lubricating products that right ba involved in the fibre conditioners, Raccrr.seda tion was made that further information concerning this potential hacard be obtained and forwarded to each ccordttae member, Toxicological informs^tier, pertinent to other materials coroconly used in member plants (solvents, degraasers, etc,) would';Xco be obtained and disseminated. 3, Tnr: Committee reviewed the practices and methods of maintenance and' opera tion of duct control systems. Since the standard dust survey methods arc lengthy .and costly procedures, it was the consensus that assurance of the effective operation of a ventilation control system could be obtained- ) through frequant and regular checks of air flew and pressures. It -.-as rccc:.cr.er.dod tiiat an iriaial relationship between satisfactory dust counts and operating pressures of the syster. be established, Suosequent *J Air Hygiene Comittee Meeting -2- checks ox the system trith the r.snanter would indicate whether t; e system was operating as designed Such a test procedure is both, sieiole and rapid The techniques of systematic inspection were reviewed and it was unanimous ly agreed that regularly scheduled, periodic inspection was an essential element in neir.iainin" the `icier.cy of the system, A corollary cf this was the preventive naintena i approach to bag, hoed and pipe replacement. John Beatty reported an affective design of dust control at the loans. Brewings and pictures '.dll be distributed when received. H.

Appropriately one vsebs hospitalisation per patient would ce necessary for the studies which would include: 1. A ccnplete medical ar.d industrial history, physical examination, and routine laboratory studies including x-2*ays of the chest ar.d electrocardiograms. ,2 Complete pulmonary function studies including merits of the vencilaticn, degree of emphysema respiratory gas exchange. 3. Cardiac catheterization to determine the pressure ir. the pulmonary circulation ar.d to correlate these with the clinical features and the pulmonary function studies. U. Lung, biopsy under local anesthesia in selected cases to correlate the pathological features with the clinical and laboratory findings. It is indicated that the hospital charges would approximate .000, per patient. The cost to the r.:enber company would, of course, *\ include the additional expenses of transportation, wage loss, etc, A C-rouo Hospitalisation plan might absorb a portion of the costs. Report of all medical data for each patient would bo forv-rded to the co.--.pany physician ar.d to the family physician, if desired, Following a series of studies, Dr, Thecdos would suttaarise and report his findings to the Instite membership. This type of investigation is of considerable value to each partici patiny 1-ember and to the Institute as a whole, The results of the study of the patient would indicate objectively the evaluation of cnv.se and extent of disability. 3ir.ee the usual case sent for thi: examination 'would be a current or potential uoris.ven's compensation occupational clisa.ase claim, tl'.is report would assist in deterninin; the validity of the claiv.i ai'.d the a:: tent of the disability and therefore, the liability. 2 Autopsy Study, \' The wr.thologica! arret analytical studies of autopsy specimens would s-K i'roposal for /.so os tools Kesoarch wb* 2t Autopsy specimens -would be obtained and forwarded by the plant physician.

The individual reperis *..111 establish, ir. a v.ann-or not possible by x-ra.y and clinical diagnosis, the nature and extent of the disease process. This \;ill have important bearing cm Workmen's Compensation liabilit for a particular- case. After series of cr.se studies. Dr. Schemers -.rill sunnarice and rap are to the Institute m embership his findings and observations. While animal experimentation has contributed greatly, the autopsy studies can develop even more complete knowledge of. the disease process; which in turn can lead to more effective medical and exposure control. Industry participation in these programs would insure advance in 1-siical Knowledge regarding Asbestoeis. -.Since the cares in any one company are so few, the cumulative industry experience is necessary to provide a large enough sample to produce valid data. The cost for each member is ncminel and ir.-mediate value is obtained through ths case reports which provide a basis for equitable settlement of Worknen*: Compensation claims, While the Beard of Governors has approved these programs in principle, vs desire to have a direct indication from each member campany as to '..bather they 'dll participate ir. them. It is uni-ere tori thr.t such right require clarification or modification of some management policies. Would you kindly review the above proposals and indicate th9 intent of your'company regarding them. - Should general participation be agreed to, complete details, procedures, addresses, etc, will ce forwarded each member for distribution to appropria company personnel, H.
