Hernia Fiberglas Health Hazard Investigation WALTER J. SIEBERT M.D. St. Louis Missouri THal development and use of a new basic mateTHal develuently gives rise to a question as to the possible health hazards for workers handling the material Glass fiber products now widely used for thermal and electrical insulation are still of such comparatively recent origin that the question of a possible health hazard is not unnaturally associated with them 2. Eye ear nose and throat infections 3. Dermatitis Fiberglas a Form of Mineral Wool FIBERGLAS is true glass but chemically it is substantially identical with mineral wool It can properly be classified as a new refined form of min- eral wool The fact that mineral wool has been used for many years without causing any known industrial diseases while by no means conclusive in itself gests that there is nothing in the inherent sug- characteristics of Fiberglas that is likely tpohyisnitcrao-l duce any serious occupational hazard The chemical and physical characteristics of binders used in manufacturing and processing Fiberglas like the chemical and physical characteristics of the glass fibers are not of a kind from which serious in- dustrial health problems would theoretically arise This conclusion is based upon examination of formulas used in the manufacture and processing of Fiberglas products o ene (he ap cme sempr?e ny eg ee TP 9 cre weet: sere tt - Aeagnmmctay 78 This association while it is to be expected because of the newness of the products is due in part to special circumstance The word glass is surrounded by connotations which suggest a hard shatterable transparent material Although Fiberglas is glass in a new physical form and with physical properties which make it unrecognizable as glass by persons who are familiar only with glass in its more conventional forms the old connotations may cling to the new products 1. No free silica is present in the material known as Fiberglas 2. No carcinogenic hydrocarbons or other hydro- carbons could be present in Fiberglas because of the extremely high temperatures employed in fusing the batch during the manufacturing process 3. No harmful fumes could be given off since substances are present in the Fiberglas which woulndo volatilize within the recommended service 4. Absent from Fiberglas is any free sodriaunmgessili- cate Purpose of the Investigation 5.

U. GARDNER Director Saranac Laboratory has reported on the researches which the Foundation sup- ports at his institution saying in part . We have been studying the effect of inhaled glass wool Ap- parently even the finest textile glass set up as an atmospheric dust is not inhaled in appreciable concen- trations and does not produce any dangerous effects " upon the lung A further report on DR GARDNER'S work appears in the Annual Report of the Saranac Laboratory for the Study of Tuberculosis of the Edward L. Trudeau Foundation for the Year 1940. The following statement is made on page 11 of the report 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 short lengths the finest textile glass that is made but none of the fibers that are floating in the air can be found in the lungs of the exposed animals Their tendency unlike that of asbestos to form like masses upon any object with which they come in contact probably prevents their inhalation Slight amounts of chronic inflammation similar to those observed with other harmless dusts have resulted from accumulated particulate debris These very fine fibrous particles are the product of the violent beating used to break up the material ray Plates of Employees THE author examined several hundred stereoscopic ray plates of the chests of employees of OwensCorning Fiberglas Corporation These were selected at random by the author from the files of some 1500 plates taken since the company in 1939 instituted the policy of making ray plates of the chests of all Newark employees Among the plates selected for special inspection were those of employees working in the batch house where the raw materials for Fiberglas are han- dled and the plates of employees with records of sili- cosis Beginning in May 1939 serial stereoscopic chest films were made of the 15 men who are now working or who have worked in the batch house A repeat examination of all of the men was made in June 1941 In no case was there any radiographic evidence of pul- monary disease : . Three cases of silicosis were discovered by the com- pany None of these men had ever been employed in the batch house but their employment does require the handling of Fiberglas products It is the policy of the company neither to refuse employment to nor discharge any man for whom safe employment can be found The following covers the occupational histories of these three workers . 1. CASE No. 1 worked for another company as a molder from 1924 to 1929 and roentgenograms of the chest were made in 1929 because of the presence of tu- berculosis in his family Chest plates were again made in 1936 because of suspicion of silicosis He'was first employed by Corning Fiberglas Corporation on June 6 1940 2. CASE No. 2 was employed as a bottle blower and machine operator from 1901 to 1980. He was first em- ployed by Corning Fiberglas Corporation on March 26 1941. Silicosis was diagnosed following an 1. Appearing in News Edition American Chemical Society Vol XII page 402. April 10 1941 ray examination of the chest made on May 12 1941 3. CASE No. 3 worked for 12 years as a molder be- fore entering the employ of Corning Fiberglas Corporation on October 25 1939. Silicosis was diagnosed following an ray examination of the chest on November 1 1940 In each of these silicosis cases there is a sufficient causative factor in the man's previous employment history or other circumstances and the evidence is entirely inadequate to indicate that the condition of any one of these three men should be attributed to any silicosis hazard encountered in handling Fiberglas even assuming such a hazard to exist Physicians Give Fiberglas Clean Bill XAMINATION of the records of disability and absenteeism in the office of the plant physician of the Corning Newark plant reveals that there is no unusual incidence of respiratory infections among Corning employees Statements furnished directly to the author by Newark physicians whose practices are limited to eye ear nose and throat diseases and who are in no way affiliated or associated with the company indicate that these specialists notice no unusual incidence of respiratory disturbances among their private patients employed by the company as compared with their private patients who are not employees The following letter dated June 17 1941 written to the author by JOHN E. HENDRICKS M.D. of Newark is typical of letters received from Newark eye ear nose and throat specialists " am one of five E.N.T. ear nose and throat specialists located in this city I have practiced my specialty in Newark for three years following a year residency in an Eastern hospital During these three years I have treated my share of Corning employees I can safely say that I have noticed no unusual preponderance of head or throat infections among these people as compared to my other patients who are not employed there If I ever make a table showing percentages of different diseases that I have treated I feel sure that there would be only a normal proportion of Corning employees in each classification On the basis of the evidence the author finds that workers handling Fiberglas products are subjected to no special occupational hazards that manifest themselves in eye ear nose or throat disorders pulmonary disorders diseases of the upper or lower respiratory system or diseases of the intestinal tract Temporary Skin Irritation employees of Corning Fiberglas Cor- Naporation Naporation engaged in handling Fiberglas products occasionally suffer a mechanical irritation of the skin for a few days at the start of the job Except for extremely rare cases of workers who may be allergic to an ingredient of binders or lubricants used in processing glass fibers the irritation disappears within a few days The new workers apparently become immunized against the action of the fibers and they suffer no further discomfort The company recommends that workers wear clothing loose at the neck and wrists and that they use plenty of warm water and soap when the day's work is done Soap and water has proved most effective in removing particles of fibers whether of glass or any other material from the skin The company has found that there is seldom if ever need of gloves armlets or other protective clothing In the absence of gloves or similar protective clothing there is less tendency for fiber particles to be rubbed into the skin ;

This represents a gross yearly incidence of 2.62 of the average industrial complement of 16,287 workers during this period Nineteen cases have not been included in this study because the nature of the accident or the location of the injury bore no possible relation to safety helmets or skull guards The remaining 195 cases represent a yearly incidence of 2.4 of the average industrial complement In other words one in every 42 workers has a head injury every year Time Due to Head Injuries Head Injuries -An Analysis With Reference to Accident Prevention LT HYMAN LIEBER MC V S U.S.N.R. Navy Yard New York HE U. S. Navy Yard at New York recently instituted a policy requiring the wearing of safety helmets by all workers exposed to head injuries It was considered desirable to prepare an analysis of head injuries for a period preceding the new regulation to serve as a basis of comparison for similar studies after the general adoption of skull guards Special attention was therefore directed to injuries of the skull scalp and forehead within the area that can be protected by safety helmets This report is presented as a NEKLY 100 of the cases 5.1 were serious enough to require pass These 10 men lost 77 days or an average of 7.7 days each The longest period of dis- ability was 40 days The 10 pass necessitated by head injuries ac- counted for 1.63 of the 611 tabulatable injuries from all causes during the period of observation and the time loss they occasioned was 1.02 of the 7904 working days lost because of all fatal accidents during the month period Comparative Hazard of Head Injuries THE incidence of head injuries among the various trades varied markedly TABLE II Average Number Head Employed Injuries Yearly Incidence % TABLE I.
