Page 2825 1 the lung tissues examined to determine the nature and 2 extent of dust reaction. 3 The tissue was also analyzed to estimate the 4 amount of Kaylo dust retained in the animals for 5 indefinite periods of time. 6 The conclusions of research work done with 7 Kaylo dust on animals were: 8 1. There is no possibility of developing 9 silicosis. 10 2. There is no danger of developing 11 asbestosis with normal handling of Kaylo products. 12 Tests show that continued exposure to 13 concentrated Kaylo dust inhaled over long periods of 14 time was capable of producing in animals increased 15 tissue growth typical of asbestosis. Reaction was 16 milder than what pure asbestos dust would produce. 17 The dust was slightly unfavorable. 18 Influence upon tuberculous infection after extensive 19 exposure over long periods of time. 20 The final page, page 4. 21 General conclusions.
