Page 2903 1 Q Okay.

1 focus because I used an infrared filter on the Page 2919 2 camera. 3 This is the curve at the end of the quartz 4 disc, and you can see the series of discrete spots. 5 This very obviously is an asbestos 6 chrysotile asbestos crude that is blowing. 7 This particular photograph was taken at 15 8 feet per second which is 10 miles an hour. 9 Q Okay. 10 A In common speed. 11 Q That is, I guess, taken with the lights 12 off?

Page 3025 1 A Well, I would hope -- if I was having my car 2 serviced by a mechanic, I would hope that he 3 understood what he was doing and had sufficient 4 knowledge that he would recognize the difference 5 between the original part and replacement parts. 6 Q Okay.

Page 3028 1 MR.

1 Medicine at Baylor.

Page 3132 1 Let me change the facts for you then. 2 What if we were to say that instead of doing 3 these activities once a day, the mechanic would do 4 them twice a day. 5 Now, what would that result -- what result, 6 if any, would that have on your math?

1 meaningful interaction with the human body.

1 remaining.

Page 3131 1 A When I calculated, it was just slightly over 2 0.1, about .11 fiber per cubic centimeter on a time3 weighted average basis. 4 Q Okay.

1 refrain from disseminating dust into the atmosphere Page 3160 2 that wasn't necessary. 3 Q Sir, you have told us that you are a 4 certified industrial hygienist; is that correct?

1 environment where there was asbestos being released Page 3246 2 into the air, you would not have warned workers back 3 then, would you, about those hazards?

1 Q Thank you.

Page 3372 1 where raw asbestos was turned into products, friction 2 products like clutches and brakes, cloth, insulation 3 products, things in which asbestos had been a useful 4 material for the purpose desired. 5 He looked at the plants, he measured the 6 levels of dust of the various operation, and he found 7 in some instances that the levels of dust were 8 astronomically high, thousands of fibers per 9 milliliter of air in areas such as dumping out sacks 10 of raw asbestos and so forth. 11 He found other areas where there were lesser 12 levels of dust and some areas where the levels of dust 13 were small or even nonexistent. 14 In examining the workers, he found a number 15 of cases of lung fibrosis, about a quarter of the 16 workers or more had evidence either on X-ray or on 17 clinical exam of diffuse lung scarring. 18 He found a relationship between the level of 19 exposure and the amount of disease.

1 So they had to separate the dust measurements into Page 3382 2 total dust and asbestos dust. 3 When they did that, they found that most of 4 the time the asbestos dust levels were less than five 5 million particles per cubic foot.

Page 3561 1 are trying to figure out if there is asbestos dust in 2 the air from brakes, and you are not doing any work on 3 brakes that day, you are not really going to find out 4 how much asbestos comes from working on brakes, are 5 you?
