1 brake and clutch parts that went onto its cars and 2 trucks, it obviously knew that those parts were 3 comprised at least in part of chrysotile asbestos. 4 So when asbestos started hitting the news, 5 Ford decided to do a couple of things. 6 The first thing that Ford did was starting 7 in the late 1960s and carrying into the 1970s, Ford's 8 own research scientists started experiments to see if 9 the braking process and brake repair work would 10 release chrysotile fibers. 11 As I told you, the epidemiology studies 12 weren't in yet, so there really was no firm answer as 13 to whether brake and clutch parts could cause 14 disease. 15 So the Ford scientists started doing 16 experiments and what they found was that almost -17 that the braking process and brake repair work 18 released almost no chrysotile fibers, and that is 19 because what we talked about earlier, the scientific 20 process behind the braking process.

1 workers had shorter exposure, hadn't had sufficient Page 3392 2 accumulation of fibers to develop the disease. 3 What he found in his population was that 4. there was asbestosis,' there was lung cancer and there 5 was mesothelioma. 6 He pointed out that his work, and others 7 such as Fleischer and Drinker, had shown that the 8 average level of exposure of insulators was less than 9 five million particles per cubic foot. 10 Most of the data suggested it was around 1 11 to 2 million particles per cubic foot, but that 12 despite being exposed to this level, if you gave 13 enough years of exposure, disease occurred. 14 And, therefore, the five million particles 15 was clearly too high. 16 Q Doctor, this was published at the, I 17 believe, December 31, 1965, this report?

1 is that right?
