Dear Ur. Prioes Mr. Belknap has disoussed frith me your inauiry relative to the possible deleterious effects f handling glass wool, particularly frith respect to possible dermatitis resulting therefrom. In only two or three rare instances have ire heard of any ill effects resulting from the handling of glass irooli V ery occasionally an individual finds that his skin beoomes slightly irritated, Just as some individuals find their skins sensitive to various dyes"^bomsonly used in the manufacture of clothing and costume Jewelry. Tie have made considerable investigation in connection with our employees, and have been advised that in those rare instances where irritation is produced, it is relieved by an application of soap and water. . Because of the recent silicosis epidemic we anticipated that wild statements might be made relative to possible damage resulting from the inhalation or ingest-ion of fine particles of glass wool. Accordingly we had experiments conducted under the auspices of cr Dr. Leroy U. Gardner of Saranac Laboratories, Saranac Lake, New York, and Professor Phillip E. Drinker of ^ the Harvard School of Public Health. Our own opinion p that the product was harmless is' borne out in the ' 3 reports of these two experiments, copies of which are enclosed for your information. hho nOcf^) Ow en s -Illin o is Gl a s s Com pany - 2- .
