Dear Hr Luft
After an extended absence from the city I find on my return your letter of May 19 and I regret that our reply is thus unavoidably delayed
We are glad to respond to your inquiry about health and handling characteristics of Fiberglas materials Although Fiberglas is a basio material that has been in use for more than 10 years it is right and proper that anyone unfamiliar with it should ask questions of the kind that you have set forth and you are entitled to all the pertinent data For that reason this letter must be long
We enclose a reprint of an article entitled Fiberglas Health Hazard Investigation which appeared in the January 1942 issue of INDUSTRIAL MEDICINE The
author is Er Walter J. Siebert of St. Louis As indicated in the opening . ^aragraphs Dr. Siebert wrote the article to summarize an investigation made by him during June 1941 for St. Louis Local No. 1 of the Asbestos Workers Union Dr. Diebert is pathologist and director of laboratories in five hospitals in the Ct Louis area Formerly he was assistant professor of pathology in the School of Medicine in Washington University This articole was abstracted in the February 1942 issue of IZDUSTRIAL HYGIENE DIGEST A reprint of the abstract is
enclosed
Among the points covered in Dr. Siebert's report of his investigation are the following
Since 1934 manufacture of Fiberglas thermal and acoustical insulation has been centered in Newark Ohio where hundreds of employees have been continuously exposed to the material in all stages of manufacturing fabricating and packaging operations On the basis of this experienos covering millions of man hours of exposure we have prepared

Concerning ^ stna'sexperience with the Fiberglas group now numbering nearly 3,000 employees we respectfully direct your attention to
Exhibit F -- Photostatic copy of letter dated June 11 1941 from ifr John A. Hill Toledo General Agent of Aetna life Insurance Company to Mr. Edward C. Ames of Corning Fiberglas Corporation containing these statements
The health of your employees has been better than average This is evidenced by the fact that we now have in effect a 35 reduction in rate on both the Sickness and Hospitalization insurance carried by your employees This is the result of nearly four full years exposure and develops a rate lower than any similar industry that we have insured In addition we have Hospitalization coverage which is developing a Loss Patio after over three years experience
far lower than almost any of the 200 industries we have
insured in Chio
As a further evidence our asualty Company carries what is known as Products Liability at an extremely low rate and no claim has ever been presented indicating of course that there is no hasard in the use of fiberglas or any of
its products
Although your compensation insurance is carried with the
State our Company does have the coverage on your new plant in Ashton Thode Island and is writing this at a rate of approximately forty cents a hundred which will indicate how safe we regard the risk to be - not only from an accident view point but from an occupational hazard view point In other words from our own experimmee
we do not feel that there is any different hasard then
from any normal manufacturing operation and we feel the hasard is much less than in the manufacture of Rockwool Slagwool Asbestos or any of the called 85 magnesia
products
Aetna's appraisal of the lung hasards and the corresponding underwriting risk involved ~= as compared with other materials used in the insulating trades -
is further detailed in
Exhibit G -- Multilithed copy of letter dated June 21 1941 to ir Hill from Kr Talter S. Paine Manager of the Engineering and Inspection Department of the Aetna Casualty and Surety Company containing this statement
I believe that most articles covering occupational disease exposure definitely warn of the hazards of asbestosis grow ing out of the use of asbestos Relative to the use of fiberglas rook wool or slag wool I have discussed this matter very thoroughly with our Fedical Department insofar as it applies to the installation of glass wool and its
relation to silicosis and I know of no better answer to give you than their direct statements
01 501 1078

We may definitely state that this is not possible
tased upon the established fact that silicates of
which glass wool is composed will not produce silicosis or a similar condition
Additional evidence that you may wish to consider is
Exhibit H -- Photostatic copy of a letter dated Catober 3 1941 to Mr. Paine from Mr. J. Dewey Dorsett Manager Casualty Department Associa tion of Casualty and Surety Executives and attached list of member companies
In answer to your inquiry as to whether we have received
any reports from our Member Companies of claims alleging
the contraction of silicosis or similar lung disease from Fiberglas or glass wool as distinguished from mineral wool
a search of our records indicates that no such claim has
been reported
Cypical of letters in our files from manufacturers using Fiberglas insulation is

Raker Works kanager of The Moore Corporation range manufacturers Joliet Illinois to A. C. Brauer Supply Company Fiberglas marketer St. Louis Mr. Moore's letter contains
this statement
We have used this material Fiberglas insulation now for approximately a year and believe it to be every bit as efficient as the various makes of rock wool and slag wool on the market today Besides this we think it has one great advantage of being a muon cleaner insulation than the average run that you find as it is almost entirely free of any kind of suot material and is practically dustless This is to our advantage as wo have had some materials in our plant that made it necessary for our mo to wear respirators while handling it This material however is clean enough for us to eliminate the use of
respirators in our present set
For many years Fiberglas insulation has been used in Budd Streamlined trains <f

and throat specialist
We are informed that an article by Dr. Schols describing the use of Fiberglas yarns for surgical sutures will appear in the
June 1942 issue of THE AMERICAN JOURNAL OF SURGEH
Besides the use of Fiberglas yarns for surgical sutures another example of a humanitarian of Fiberglas is as a tracer thread in surgical sponges described by Edward F. Lewison M.D. in an article entitled A Safe Surgical Sponge on pages 1-3 of SUEGERY TYNECOLOGY AND OBSTETRICS November 1989 and discussed further in another article by Ir Lewison entitled Mayable Cause as a Factor of Cafety in Surtical Operations on pages 39-40 of the January 1942 issue of the
SULLETIN OF THE AMERICAN COLLEGE OF SURGEONS and in an article entitled Radio-
paque Thread

In addition tape woven of Fiberglas continuous filament is being supplied under .rmy specifications for use in medical field kits to filter blood plasma during
transfusions made to reduce shock This use is described in a current advertise-
ment reprint enclosed which was approved by Army medical officers before release
It is also described in the Kay 1942 issue of SURGICAL BUSINESS We believe it is significent that Fiberglas yarns are used by the medical profession in connection
with these applications and that they indicate there is nothing toxic in the
The evidence cited above rests on our experience in the manufacture and marketing

you will agree however that in any scientific discussion of the subject this

Study of Tuberthe Year 1940
V. ardnert
The apparent lack of pulmonary damage from exposure to glass wool dust is being demonstrated by an inhalation experiment For over a year animals have now been exposed to as high a concentration of this material as could be maintained with no serious effect upon their lungs The dust has been produced by breaking into snort lengths the finest textile glass that is made but none of the fibres that are floating in the air can ^,,e found in the lungs of exposed animals Their tendency unlike that of asbestos to form like masses upon any object with which they
comme in contact probably prevents their inhalation Slight
smounts of chronic inflamation similar to those observed with other harmless custs have resulted from accumulated
particulate debris These very fine fibrous particles are the product of the violent beating used to break up
the material
