Bayotmt, H. J. PLAINTIFF'S EXHIBIT 0H/3.CK) IHI3 | , N.' C -V *A Mac* 26, 1972 Dr. Joseph X. Magoner, ScD Director, Eivision of Field Studies St Clinical Invcntigutions National Institute of Occupational Safety St Health 550 Main Street Cincinnati, Ohio 45202 Lear Joe: From the presentation cade by you and Bill Johnson at the AI!IA Conference last vc^:c, it appears to me that MIOSH is grasping at straws and will stoop to almost any level in its efforts to implicato Chrycotiic as a uajor causative agent of a:-jerboa related carcinogenic disease. tile vour representation, of ou:' Kan heir. operation as a plant processing practically only Chrysotilo i3 correct insofar r>..*j present and recent past conditions are concerned, it certainly is not the cose in regard to exposures that occurred in tnis plant during the early 1910' o, particularly during V.'orld War II. Consumption of Amo sits fibre at Mar.hoin iron 1911 througn 1911 averaged approxi mately 750,001 pounds per year almost all of which vrent into products that involved a major proportion of relatively dirty manual fabrication and handling, llich of this was dono under high priority cn defense contracts for the U. S. Navy. Ths product was a special i.ovon Anosite !:eat insulating blanket or Mattress for high pressure stcan equipment aboard Naval vceceic. .isosite was used in spite of its greater dust producing potential because Chrysotila asbestos was in short supply and could not be obtained In the quantities needed for this high volume high priority requirement. Operations involved blending and opening of the bull: Amosite fibre in our Preparing department^ follov:3d by carding into heavy' roving or wick. The wick thus produces was then woven in combination \/ith Chrysotilc yarn on a cpeclal lend loon in our Tape V.'eaving department to produce a continuous blanket approximately 30 inches vide. This material then was manually handled and fabricated into custom shaped insulation Mattresses in which the Anon it c was encased inside l.-'.yers of regular Ch"y,Totilo cloth for mechanical protection. This was a very dusty Job requiring ?Ju..ost/M:.:'d.'..ork,- co.r.3 of viiich vjs porfcrv.ed sy ..omen. buo to its high bulk, the finished product required special packaging, which also had to bo dune manually. All the op'-rationr? involved were considered to bo .`il'Tiificantlv dustier then typical operations v;ithin our plant. Fortunately, .'O l were terminated in 1945, although the wquipmsnh rcirudned installed and was weed to produce a ft"./ Job lot orders in 191b and 1917. Lr.

Johnson':j presentation to she offset that tho mortality figures r.iven represent results of oxpocuru practically only to Cluysosilu. It in entirely pcaoibio that root, if not all, of any cn.eeso mortality that appears in tho records of Itunhoin employees from epproxiratoly 1950 on eight Lj3 attributed to Amouito exposure that occurred in the aforementioned inouiatic blanket production operations. in addition to thio Aciooito application, co.-'.ctino prior to I960 through 1970 Ksnhoia produced a npocirJL furor.ito insulating tape on an intermittent basis, hailo this pi*oduct involved only about 1C0J pour.du of Amoaito For jvj.r, tho exposure wnilo proceeding thio material flight bo considered oignifiaent by coma people.

I tllrJc it is doploraolo tnat thia implication already has been given such vddo circulation as v;.io afforded by presentation at tho conference in San- rrancisco, but suppose it is too lata to do much to amend that now. Floaso to assured of our dosiro and intention to continue to cooporato in .`;iJ3h'3 on-going studies regarding asbestos and related health hacaras. ho recognize tr.o extreco r.ocd for prompt completion of thio \ror'K and are anxious to do whatever can in order to help oxu-editc tho pyojpran. However, at tho sar.o tir.o w consider it absolutely osscntinl that tho studies includo all facts and elements t;u.t uiri.t bo of significance in arriving at tho final conclusion. Utharwiuo, actions tri:cn on the basis of theso studies cannot accurately servo tho bast interests of tho public. Sincerely jcura, I. !i. 'heaver w occ_"-3or.ra. Gainer /Daly ,arun
