                  MEMORANDUM POt                                      Mr. C. W. Myers
                  Subject:                   Problem of Asbestos Exposure


                            The lung disease known as asbestosis has been recognized
                  for several decades as an occ~pational disease arising from the
                  inhalation of asbestos particles. More recently, medical litera-
                  ture is burgeoning with reports implicating asbestos fibers deposited
                  in lung structures as a cancer-causing agent.

                            In brief, there appears to be a statistical relationship
                  between the presence of asbestos fibers in lung tissue and an
                  increased frequency of lung cancer, pleural mesothelioma. gastro-
                  intestinal cancer and peritoneal mesothelioma.

                            We have recently become aware of cases of Shipyard employees
                  which bear these diagnoses; al~(r,. ·"asbestos- bodies If have been demon-
                  strated in lung tissue~   ~

                            Recently NASA has been confronted with a claim for wrongful
                  death due to malignant tumor, said to be arising from the stimulus
                  of asbestos. This claim was allowed as an occupational disease.

                            Despite the wide-spread dooumentation of the statistical
                  validity of the relationship between asbestos and tumor, it is
                  my feeling that we cannot accept such evidence as whole cloth. All
                  of these studies have been made with the avowed purpose of demon-
                  strating a relationship between this agent and the disease entity;
                  none have been slanted in the opposite direction, i.e., to demon-
                  strate that there is not. It is thus my feeling that these
                  researchers carry an observer's bias and are, therefore, not
                  necessarily valid outside of their own context.

                            Because there is a long delay (average given in different
                  articles from 27.4 to 38.5 years) between the onset of exposure
                  to asbestos and the appearance of tumor. A unique problem exists.

                            I would propose in preparing a solution to this problem
                  that two avenues must be utilized:




..   ~~-   .. '   .. ' " .., ..        '_ _
                                  ~~_._.   ._.1_31"_'11._ _ _ ____ r ......-... ......

                                                                                                                                                   NNS-MOR-006330
                                               ,   ,~




                                - 2 -


    (1)    Environmental survey and control - the use of asbestos
           falls easily into two major categories in the Shipyard.
           l"irst, the preparation of and installation of irwula-
           ting material in shapes" usually prepared in the Pipe
           Coverer's Shop. Second" the removal and replacement
           of old insulation with new in ship repair.

           Sample studies need to be made to estimate the current
           airborne burden of asbestos particles and the environ-
           ment where they may represent an inhalant hazard. From
           present studies, some conclusion may be drawn as to past
           experience in these areas. Control measures should then
           be instituted" based on the indicated need, but which
           should include specific protection of the respiratory
           tract by preventing the particles from becoming air-
           borne in the ambient breathing air or that the particles
           from the work place be removed by draught ventilation
           and \'Jet collection, use of vacuum cutting tools, and
           meticulous house cleaning procedures, whether for new
           or old work. Actual use of respirators may prove to
           be necessary in many instances. This is essentially
           a problem for an industrial hygienist.

     (2)   An appraisal of whatever defensive position we may assume
           will also involve the historical study of individuals who
           have been exposed to asbestos in the course of their
           employment. Rather than explore the fringes of this
           relationship, it is proposed that death certificates
           of individuals employed in Pipe Coverer's Shop be
           reviewed. A ready source of review would arise from
           the records kept at the Aetna Insurance Office to which
           access would be required. This would produce certificates
           only for those individuals who retired, became disabled,
           or died while still in the employment of the Company.
           If this sample is not statistically significan~ it is
           suggested that the review be extended further backwards
           in time, utilizing other sources of death certificates,
           including the Bureau of Vital Statistics at the p1ace of
           death. This may be facilitated by utilization of social
           security records and a valid search could be made without
           undue difficulty back to 1935. Prior to that, more
           difficulty would be encountered and this should not be
           attempted unless sufficient information has not been
           obtained.

          After review of these records, a statistical correlation of
our own records can be made and an evalua'tion of our own situation can
thus be presented.

          The accumulation of cases in the past year and one-half
has been sufficiently large for me to represent this to you as a
problem for emergent attention.
