The data which have been presented show that respirable fiber concentrations in the small fiber operations are many orders of magnitude higher than those found in standard insulation operations. In addition, the very small diameters and short lengths of these airborne fibers tend to make them potentially more respirable. All worker population studies to date concerning the health aspects of glass fiber exposure have been done on worker populations exposed to low fiber concentrations in large fiber insulation operations. No worker studies have been done with populations exposed to small diameter fibers at concentrations found in this study. In fact, there does not presently exist such a population for study as exposure durations of these populations are extremely short. Recent animal studies by Dr. Stanton of the Cancer Institute and Dr. Pott of the University of Dusseldorf have shown small glass fibers to be carcinogenic when injected into the pleural cavity of experimental animals. In view of these studies, it would appear prudent that exposures to respirable glass fibers be kept at an absolute minimum through the use of appropriate engineering controls and material handling methods.
