WEBVTT NOTE Machine transcript of the film's sound; not yet checked. 1 00:01:59.840 --> 00:02:03.520 Tremendous heat and pressure, striving to find release. 2 00:02:04.500 --> 00:02:10.600 When the crust was torn by subterranean upheaval, molten rock spewed upward. 3 00:02:11.240 --> 00:02:16.820 In time, millions of years of time, the molten rock and these 4 00:02:16.820 --> 00:02:19.180 crevasses cooled and hardened. 5 00:02:19.460 --> 00:02:24.880 Then the hardened rock itself was beset by further disturbances that left it 6 00:02:24.880 --> 00:02:25.880 heavily fissured. 7 00:02:29.450 --> 00:02:31.710 Theory says that through these fissures 8 00:02:31.710 --> 00:02:34.670 flowed hot, mineral-bearing waters and gases. 9 00:02:35.350 --> 00:02:38.350 And as the Earth spun off more millions of years, 10 00:02:38.610 --> 00:02:41.610 they crystallized, and in so doing, 11 00:02:42.210 --> 00:02:46.650 formed the most unusual and useful mineral fiber known to man. 12 00:02:49.010 --> 00:02:51.810 Largely unseen, seldom recognized, 13 00:02:52.450 --> 00:02:54.930 it has played a tremendously important role 14 00:02:54.930 --> 00:02:57.510 in the improvement of our standard of living. 15 00:02:57.510 --> 00:03:01.230 As you might expect, the Greeks had a name for it. 16 00:03:01.390 --> 00:03:04.930 They called it the unquenchable, indestructible 17 00:03:04.930 --> 00:03:08.170 stone. They called it asbestos. 18 00:03:10.390 --> 00:03:15.670 Unaffected by fire, unchanged by weather, 19 00:03:15.830 --> 00:03:17.910 untouched by 20 00:03:17.910 --> 00:03:23.470 time's dark captains, rust, rot, and decay, asbestos 21 00:03:23.470 --> 00:03:26.070 possesses rare qualities for which 22 00:03:26.070 --> 00:03:31.980 it stands alone. So fine are the 23 00:03:31.980 --> 00:03:35.320 individual asbestos fibers that it is only through the 24 00:03:35.320 --> 00:03:39.560 eye of the powerful electron microscope that they can be properly studied. 25 00:03:40.320 --> 00:03:41.940 Even when magnified 26 00:03:41.940 --> 00:03:47.580 31,000 times, they appear delicate, gracefully hiding the fact that they are 27 00:03:47.580 --> 00:03:48.720 incredibly strong, 28 00:03:49.000 --> 00:03:53.160 stronger than many types of steel wire of the same thickness. 29 00:03:53.900 --> 00:03:55.880 At the same time, they 30 00:03:55.880 --> 00:03:59.620 are remarkably flexible and highly resistant to most chemicals. 31 00:04:00.520 --> 00:04:05.120 Man has never been able to duplicate their fibrous properties or colluse. 32 00:04:08.160 --> 00:04:12.260 Asbestos deposits have been found in widely separated parts of the world. 33 00:04:12.400 --> 00:04:15.160 But only in Canada, Africa, 34 00:04:16.680 --> 00:04:21.640 and Russia have abundant quantities been discovered. 35 00:04:22.260 --> 00:04:26.800 For the geologists of Johns-Manville, it's a never-ending search. 36 00:04:26.800 --> 00:04:32.570 The world's largest asbestos mine is the Johns 37 00:04:32.570 --> 00:04:35.010 Manville Jeffrey mine at Asbestos 38 00:04:35.010 --> 00:04:38.310 Quebec, so named for nature's magic mineral. 39 00:04:39.010 --> 00:04:41.570 Most deposits have a 10 to 25 40 00:04:41.570 --> 00:04:47.310 year life, but this one has been yielding for more than half a century and even 41 00:04:47.310 --> 00:04:52.330 under the pressure of growing demands, it is expected to produce for another 100 42 00:04:52.330 --> 00:04:58.690 years. The more than 500,000 tons of top- grade chrysotile fiber extracted 43 00:04:58.690 --> 00:05:03.550 yearly are responsible for nearly a third of the world's total supply. 44 00:05:04.070 --> 00:05:05.070 The 45 00:05:04.710 --> 00:05:09.810 men who began this open pit are gone. Perhaps a few who were children in that 46 00:05:09.810 --> 00:05:15.150 time can hazily recall its beginning, but for most of the people of the town of 47 00:05:15.150 --> 00:05:20.950 asbestos there has always been the pit. By drilling and 48 00:05:20.950 --> 00:05:23.290 blasting and digging it 49 00:05:23.290 --> 00:05:29.200 has grown. The ore body taken from 50 00:05:29.200 --> 00:05:34.000 the earth. But pit mining is not the only 51 00:05:34.000 --> 00:05:37.740 method used to extract asbestos bearing ore from its deposits. 52 00:05:38.220 --> 00:05:39.480 Another productive 53 00:05:39.480 --> 00:05:45.400 way is called block caving. In open pit mining the asbestos ore 54 00:05:45.400 --> 00:05:46.680 is removed from 55 00:05:46.680 --> 00:05:51.820 the top of the deposit. In block caving, the ore is taken from underground. 56 00:05:52.880 --> 00:05:53.880 Each 57 00:05:53.560 --> 00:05:58.120 section to be caved is 200 feet square by 400 feet high. 58 00:05:59.100 --> 00:06:01.180 Some distance away, a 59 00:06:01.180 --> 00:06:05.940 main shaft is sunk from the surface to a depth below the area to be caved. 60 00:06:06.640 --> 00:06:07.640 From 61 00:06:07.320 --> 00:06:12.600 the main shaft, a tunnel called the haulage drift is driven in the direction 62 00:06:12.600 --> 00:06:18.560 of the section to be caved. Then other tunnels called cross cuts are driven 63 00:06:18.560 --> 00:06:23.200 under the area to be caved and at right angles to the haulage drift. 64 00:06:24.260 --> 00:06:25.320 Through them 65 00:06:25.320 --> 00:06:31.160 run the mine cars. Now another system of tunnels called slusher 66 00:06:31.160 --> 00:06:32.520 drifts are driven 67 00:06:32.520 --> 00:06:38.100 directly below the section to be caved above and at right angles to the cross 68 00:06:38.100 --> 00:06:44.560 cuts. The floors, walls, and roof of all slusher drifts are heavily reinforced with 69 00:06:44.560 --> 00:06:50.400 concrete. Through the roof of the slusher drifts, draw points 17 70 00:06:50.400 --> 00:06:53.000 feet apart are pushed up into 71 00:06:53.000 --> 00:06:58.600 the section to be caved. The ore body above the draw points is now 72 00:06:58.600 --> 00:06:59.820 drilled and blasted 73 00:07:00.230 --> 00:07:05.840 and the asbestos laden rock tumbles down through the draw points to the floor of 74 00:07:05.840 --> 00:07:06.840 the slusher 75 00:07:06.280 --> 00:07:12.040 drift. Now the crab-like slusher drags it to a point over a 76 00:07:12.040 --> 00:07:13.360 crosscut where it 77 00:07:13.360 --> 00:07:16.380 falls into the 10-ton mine cars waiting below. 78 00:07:16.660 --> 00:07:19.120 The beginning of a long journey. 79 00:07:19.380 --> 00:07:24.820 Now crude ore, soon useful asbestos fiber. 80 00:07:26.920 --> 00:07:29.580 All traffic is controlled by a central 81 00:07:29.580 --> 00:07:33.780 dispatcher through two-way radio and an electric signal system. 82 00:07:34.300 --> 00:07:35.580 What with modern 83 00:07:35.580 --> 00:07:41.180 service facilities, repair shops, storerooms, lunch rooms, the mine is 84 00:07:41.180 --> 00:07:44.740 actually a community at work a thousand feet underground. 85 00:07:46.520 --> 00:07:48.180 At the tipple near the 86 00:07:48.180 --> 00:07:51.240 main shaft, the cars are dumped two at a time. 87 00:07:52.680 --> 00:07:55.820 The ore roars down a giant chute to 88 00:07:55.820 --> 00:08:00.900 the primary crusher on a lower level and the crude asbestos rock gets its first 89 00:08:00.900 --> 00:08:06.280 refinement underground. From the crusher it will go downward into bins 90 00:08:06.280 --> 00:08:07.720 and then a 91 00:08:07.720 --> 00:08:11.820 loading pocket from where it will be hoisted in twelve and a half ton 92 00:08:11.820 --> 00:08:16.140 mouthfuls by fast-moving skip buckets that shoot it to the surface. 93 00:08:16.800 --> 00:08:17.800 Working 94 00:08:17.520 --> 00:08:22.640 underground the miners of Asbestos Quebec utilize the most advanced mining 95 00:08:22.640 --> 00:08:28.400 methods using fast boring drills. In their many different jobs they are 96 00:08:28.400 --> 00:08:33.100 protected and guided by the highest safety standards light 97 00:08:33.100 --> 00:08:37.700 power ventilation structure 98 00:08:38.670 --> 00:08:43.560 all are important in the daily production of more than 12 000 tons of ore 99 00:08:43.560 --> 00:08:46.930 all are important 100 00:08:46.930 --> 00:08:52.850 in protecting the men who do the block caving from beneath the 101 00:08:52.850 --> 00:08:55.350 earth and from out of the open pit 102 00:08:55.350 --> 00:09:01.210 Asbestos-bearing ore, crushed and dried, comes by way of conveyors to the 103 00:09:01.210 --> 00:09:02.210 dry rock 104 00:09:01.810 --> 00:09:07.550 storage shed, where it is temporarily housed in great quantities until needed 105 00:09:07.550 --> 00:09:08.550 at the mill. 106 00:09:11.910 --> 00:09:17.850 Those stories tall, the world's largest asbestos mill, equipped with the 107 00:09:17.850 --> 00:09:19.050 most modern refining 108 00:09:19.050 --> 00:09:24.910 machinery, remarkably dust-free, designed to process up to more than 800 109 00:09:24.910 --> 00:09:26.110 tons of ore 110 00:09:26.110 --> 00:09:31.790 an hour. The mill, a towering monument to man's thought and labor 111 00:09:31.790 --> 00:09:32.990 standing against 112 00:09:32.990 --> 00:09:38.630 the sky. Into its air-conditioned immensity, the 113 00:09:38.630 --> 00:09:40.370 asbestos fiber comes to be 114 00:09:40.370 --> 00:09:45.390 stripped from the mother rock. On a series of vibrating screens, waste 115 00:09:45.390 --> 00:09:50.310 particles of rock are shaken from the fiber. Then sucked up into giant 116 00:09:50.310 --> 00:09:53.530 aspirators, it is further husked of its impurities. 117 00:09:54.030 --> 00:09:57.540 In this carefully calculated 118 00:09:57.540 --> 00:10:03.420 process the fiber is refined again and again finally to be 119 00:10:03.420 --> 00:10:04.480 tested and graded 120 00:10:04.480 --> 00:10:09.380 according to its length under quality control standards which demand the best 121 00:10:09.380 --> 00:10:15.160 from crude ore to refined fiber through the 122 00:10:15.160 --> 00:10:17.700 magic of man's ceaseless ingenuity 123 00:10:18.820 --> 00:10:23.780 now packed and ready for shipment to hundreds of different points around the 124 00:10:23.780 --> 00:10:29.540 globe all from the town of Asbestos yes Asbestos Quebec 125 00:10:29.540 --> 00:10:32.940 is a small town but more than that it's an 126 00:10:32.940 --> 00:10:38.520 attractive town a friendly place modern and up-to-date its citizens 127 00:10:38.520 --> 00:10:40.700 close-knit by common bonds 128 00:10:45.260 --> 00:10:50.360 here's the community golf course where the Bobby Joneses of Asbestos perfect that 129 00:10:50.360 --> 00:10:51.860 old swing and 130 00:10:51.860 --> 00:10:56.460 well, sometimes carry their mining ability to unusual extremes. 131 00:10:58.400 --> 00:11:04.260 The mine, and the mill, and 132 00:11:04.260 --> 00:11:06.860 the few thousand men of the town who work them. 133 00:11:07.100 --> 00:11:12.760 A small place doing a vital job, sending the fiber on its way. 134 00:11:14.480 --> 00:11:16.880 What do you do with the fiber when you get it? 135 00:11:17.280 --> 00:11:18.680 What do you turn it into? 136 00:11:19.280 --> 00:11:21.580 How does it contribute to better living? 137 00:11:21.860 --> 00:11:27.760 how does it enhance our daily lives let's start 138 00:11:27.760 --> 00:11:29.580 with our homes the 139 00:11:29.580 --> 00:11:34.280 attractive roof which protects us against fire and weather will never rot 140 00:11:34.280 --> 00:11:40.260 or decay because the shingles are made of asbestos and cement cement 141 00:11:40.260 --> 00:11:41.260 could not 142 00:11:40.920 --> 00:11:46.540 do the job alone a cement shingle would break easily without the reinforcing 143 00:11:46.540 --> 00:11:52.600 qualities of asbestos. But when asbestos fibers are added, it becomes 144 00:11:52.600 --> 00:11:58.360 strong and tough, amazingly so. Strong enough and tough 145 00:11:58.360 --> 00:12:00.020 enough so that it can 146 00:12:00.020 --> 00:12:03.280 even be made into large, flexible sheets like these. 147 00:12:06.580 --> 00:12:11.800 When these fireproof sheets of asbestos and cement are used as the exterior wall 148 00:12:11.800 --> 00:12:17.420 finish of our homes, we enjoy the permanence of stone combined with the 149 00:12:17.420 --> 00:12:23.420 beauty of vertical accent so desirable in contemporary architecture in 150 00:12:23.420 --> 00:12:28.680 traditional architecture colorful asbestos sidewall shingles give us the 151 00:12:28.680 --> 00:12:34.260 same permanence and freedom from upkeep expense not only new houses 152 00:12:34.260 --> 00:12:35.340 but old 153 00:12:35.340 --> 00:12:40.020 houses as well can have the same benefits with a remarkable improvement 154 00:12:40.020 --> 00:12:45.600 in appearance and not only outside but inside as well 155 00:12:45.600 --> 00:12:48.820 asbestos helps beautify the home with 156 00:12:48.820 --> 00:12:54.620 colorful vinyl asbestos floor tile tough asbestos fiber protects them 157 00:12:54.620 --> 00:12:56.960 against wear a swish of the 158 00:12:56.960 --> 00:13:02.880 mop makes them gleaming bright in the court of household appliances that demand 159 00:13:02.880 --> 00:13:03.880 heavy amounts 160 00:13:03.640 --> 00:13:07.420 of electricity, asbestos provides protective insulation. 161 00:13:08.680 --> 00:13:14.320 And no matter how long little Johnny plays with his electric train, asbestos insulation 162 00:13:14.320 --> 00:13:17.720 in the transformer offers similar protection. 163 00:13:19.770 --> 00:13:26.130 When we turn on a faucet and the water comes out sparkling clear, it's because asbestos 164 00:13:26.130 --> 00:13:32.050 has helped guard it from reservoir to our home in water mains of Transite, the white 165 00:13:32.050 --> 00:13:37.450 asbestos cement pipe that cannot rust. Because it is corrosion resistant 166 00:13:37.450 --> 00:13:41.550 throughout, its smooth interior stays smooth. 167 00:13:41.910 --> 00:13:44.110 That keeps the water pressure up 168 00:13:44.110 --> 00:13:49.830 and keeps the water bills down. Asbestos cement pipe provides 169 00:13:49.830 --> 00:13:51.070 a health line in 170 00:13:51.070 --> 00:13:56.610 carrying off waste from our homes to the street sewer.
