Page 1043 1 seemingly negligible proportion of fibrous asbestos is 2 sufficient to produce the characteristic reaction. 3 It was found to be impossible to break up 4 all of the fibers and about 1 percent of the air 5 suspended dust consisted of fibers. 6 The characteristic peribronchiolar fibrosis 7 developed in the exposed animals after 40 months. 8 Thus it appears that very small numbers of 9 fibers are capable of producing asbestosis, although 10 the development of the lesions is delayed. 11 The present experiment with Kaylo is also an 12 example of this fact. 13 Conclusions, page 6, number 1. Kaylo, 14 because of its content of an appreciable amount of 15 fibrous chrysotile, is capable of producing asbestosis 16 and should be handled as a hazardous industrial dust. 17 The next is our Exhibit Number Owens18 Illinois 476. It is a special hazard survey prepared 19 for Owens-Illinois Kaylo division, Berlin, New Jersey, 20 April 28th and May 2nd, 1958, by the Aetna Life 21 affiliated companies.
