New York Your thoroughgoing report of August 21 about the group at Todd Ship Yard Erie Basin is most meeting with the agree heartily with you that fow interesting and I to us in the long run as a things can eo be advantageous to know that meeting of this Bort are going ahead with I am mighty glad time that by the time this mano reaches a of this kind and program will have been held at the Todd you Hoboken a similar meeting probably Yard probably Your report confirms my belief that an increasingly effective job for our the representatives can do with the industrial hygienists plant company by constant follow and production people involved physicians engineers safetkyinally determined the They are the ones who acceptability view and it is as of our materials from a handling point of instance to get an important order to sall those as it is in the first on the basis of engineering performance The question raised by Dr. precipitation is difficult to concerning dust count and involved The answer because so many factors are relatively course in open and unconfirmed wool fibers will settle rapidly inadequate ventilation spaces it will In enclosed or confined of spaces This question of settlement is course however an settle more slowly with of the fact that Dr. Gardner's research academic one in view fibers that do gloat in the air demonstrated that such worse the are not inhalable and that at presence of such fibers would be characteristic on the job I recall a only a nuisance office of Manfred Bowditch statement Massachusetts made in the Hygiene in November 1941 by Dr. Director of Industrial Schwartz told he is not a lung pathologist he could these men that although nothing whatsoever to assure them that they had since such fibers worry were too about from fibers that could be soon and that the range of large fiber to get into the respiratory tract beyond the threshold at diameters in Piberglas materials was which such a hazard was encountered From time to time dust counts have been and at the Huntington plant by state made at the Newark plant ago a dust count was made in officials and several years Industrial Hygiene Newark Foundation by a representative of the may be deemed to exist As you probably know a hazard only if particles of certain sizes are found in certain quantities -J particles per cubic foot something like several million PLAINTIFF'S EXHIBIT if EXHIBIT 258 258 OCF SIOSSS4415 MES F-196 032 032 193 11:26 11:26 Liha In no cage wap the case was any dangerous any dangerous concentration developed as case was dangerous respirators place any our plants the branch concentration where concentration workers you know developed required where where a silicosis silicosis , respirators respirators from exposure exposurehoussielicbaecause because of handling sand hsaaznadrds er silicon silicon resulting sand transformed transformed into howev glass Once changes silicates glass and the hazard disappears changes entirely entirely different different story silicosis asbestos is the hazard asbestos fiber the the silicate silicate that involve been determined lung lung determined lung pathologists to lung hazard This asbestos fiber in crystalline microscopically crystalline in structure overlapping microscopically is snake like in appearance These many overlapping overlapping needle hydration crystals These crystals contain water water certain The asbestos fibers og - certain certain particle passages certain concentrations cause penetrate penetrate alveoli the respiratory respiratory passages they set havoc when they reach body the lungs where found in up a chemical reaction with silicosis body ZI fluids that only a understand only highly highly trained pathologists differentiate differentiate asbestosis silicosis The symptoms similar~- dyspnea shortness breath hacking unproductive cough slight elevation elevation temperature temperature etc. Thank goodness cough into temperature with Fiberglas we don't run into I think think snake barker think think act must have been sending separately you barker can of Kleen very for convincing am separately you care to inflict relief of such upon yourself Best regards Edward C.
