The pulmonary response to fiberglass dust. Report of the Committee on Environmental Health. American College of Chest Physicians


Fiberglass inhalation seems to produce a minimal tissue response in the lungs, and the reaction is one of macrophagic mobilization and is characteristic of the pulmonary response to those nonfibrogenic dusts classified as nuisance dusts. In order to merit the designation of a nuisance dust, the pulmonary response must fulfill the following three requisites:31(p5) (1) The alveolar architecture must remain intact. (2) The stromal proliferation is minimal and consists mainly of reticulin. (3) The tissue reaction is potentially reversible. Inasmuch as the pulmonary reaction to the dusts of fiber glass fulfills all of these requirements, it should be classified as a nuisance dust. 31(p5) There is no evidence to indicate that inhaling fiber glass is associated with either permanent respiratory impairment or carcinogenesis; however, the final verdict as far as the latter is concerned must await the findings of long-term mortality studies.
