WEBVTT NOTE Machine transcript of the film's sound; not yet checked. 1 00:00:35.910 --> 00:00:39.710 Fire at sea. The dread of mariners down through the centuries. 2 00:00:40.070 --> 00:00:44.810 This swift and terrible force that has destroyed hundreds of ships and taken a toll 3 00:00:44.810 --> 00:00:50.330 of countless lives reached its tragic climax in the Morro Castle disaster of 1934. 4 00:00:51.190 --> 00:00:56.350 But horrible as it was, the Morro Castle fire had one constructive aftermath. 5 00:00:56.770 --> 00:01:01.630 It focused attention on the need for fire- safe construction in subsequent 6 00:01:01.630 --> 00:01:02.930 shipbuilding so 7 00:01:02.930 --> 00:01:07.350 that similar tragedies to that which overtook this ship would not happen again. 8 00:01:08.530 --> 00:01:14.110 Soon studies were underway, facts were being sifted, and a committee had been appointed 9 00:01:14.110 --> 00:01:18.970 to determine by means of a series of practical tests the requirements of a fire 10 00:01:18.970 --> 00:01:19.970 -safe bulkhead 11 00:01:19.970 --> 00:01:25.870 material. Such a material, the committee found, must have three important characteristics. 12 00:01:26.490 --> 00:01:29.850 First and foremost, it must be incombustible. 13 00:01:30.590 --> 00:01:34.210 Second, the material must maintain its structural 14 00:01:34.210 --> 00:01:39.630 integrity in the presence of flame. Third, but by no means least in importance, 15 00:01:39.910 --> 00:01:40.910 it should 16 00:01:40.550 --> 00:01:45.670 possess sufficient insulating value to confine fires to their point of origin, for 17 00:01:45.670 --> 00:01:46.670 it is 18 00:01:46.070 --> 00:01:50.770 axiomatic that the spread of fire invariably constitutes its worst 19 00:01:50.770 --> 00:01:55.330 potential hazard and this is particularly true of fires on ships. 20 00:01:56.550 --> 00:01:57.550 As a 21 00:01:57.390 --> 00:02:01.910 pioneer in the manufacture of fire safe asbestos building materials, Johns- Manville 22 00:02:01.910 --> 00:02:06.450 was a logical company to produce a bulkhead panel material that 23 00:02:06.450 --> 00:02:11.630 would meet these specifications. Here at the Johns-Manville Research Center in 24 00:02:11.630 --> 00:02:14.450 Manville, New Jersey, the same team of scientists 25 00:02:14.450 --> 00:02:16.930 and engineers that had produced so many 26 00:02:16.930 --> 00:02:19.630 of the outstanding developments in fire- safe building 27 00:02:19.630 --> 00:02:21.850 construction went to work on the problem. 28 00:02:23.150 --> 00:02:26.110 The result was a completely new and different material 29 00:02:26.550 --> 00:02:29.970 that has proved itself ideally suited to the high safety 30 00:02:29.970 --> 00:02:32.350 standards now required on American ships. 31 00:02:33.250 --> 00:02:36.270 Moreover, these fire-safe Marinite panels 32 00:02:36.650 --> 00:02:38.870 offer the marine architect and shipbuilder 33 00:02:38.870 --> 00:02:41.350 other important practical advantages as well. 34 00:02:41.930 --> 00:02:45.070 They insulate against heat, cold, and noise. 35 00:02:45.590 --> 00:02:49.710 Structurally strong, they are capable of withstanding severe abuse. 36 00:02:50.250 --> 00:02:54.170 Yet they are relatively light in weight and easily workable. 37 00:02:54.490 --> 00:02:56.930 And with all these utilitarian features, 38 00:02:57.330 --> 00:03:00.650 their decorative possibilities are virtually unlimited. 39 00:03:02.010 --> 00:03:05.310 This panel, for example, has been faced on both sides 40 00:03:05.310 --> 00:03:07.310 with an attractive plastic finish. 41 00:03:07.310 --> 00:03:12.310 one of a number of surface treatments that are possible with this versatile material. 42 00:03:13.150 --> 00:03:17.790 But first, let's see how Marinite meets the requirements of fire safety. 43 00:03:18.710 --> 00:03:23.350 In this test, one of a series made by an independent testing laboratory in 44 00:03:23.350 --> 00:03:24.350 accordance with Coast 45 00:03:24.230 --> 00:03:29.650 Guard standards, a Marinite panel is placed in a specially constructed test furnace to 46 00:03:29.650 --> 00:03:35.070 determine its structural integrity in the presence of flame and its ability to provide 47 00:03:35.070 --> 00:03:40.710 an effective barrier against the spread of fire. With the panel in place, 48 00:03:41.790 --> 00:03:45.790 thermocouples are attached to both faces for accurate measurement of the relative 49 00:03:45.790 --> 00:03:51.750 temperatures and the furnace is ignited. Now the flames 50 00:03:51.750 --> 00:03:53.430 begin to sear the exposed 51 00:03:53.430 --> 00:03:57.010 side of the panel. Higher and higher they climb. 52 00:03:57.790 --> 00:03:59.910 As the fire rages inside the 53 00:03:59.910 --> 00:04:03.750 furnace, engineers record the temperatures at intervals throughout the 54 00:04:03.750 --> 00:04:07.950 test. This typical graph shows the test results. 55 00:04:08.610 --> 00:04:10.930 The upper curve represents the 56 00:04:10.930 --> 00:04:15.490 temperature of the exposed side of the panel. The lower curve is the temperature 57 00:04:15.490 --> 00:04:21.050 of the unexposed side. Note the wide separation of the two curves, convincing 58 00:04:21.050 --> 00:04:23.950 evidence of Marinite's high insulating value. 59 00:04:27.250 --> 00:04:29.050 After a one-hour test period 60 00:04:29.050 --> 00:04:34.310 during which the exposed side has been subjected to heat up to 1,700 degrees 61 00:04:34.310 --> 00:04:39.870 Fahrenheit the temperature of the unexposed side is below the limit of 250 62 00:04:39.870 --> 00:04:41.970 degrees allowed by the 63 00:04:41.970 --> 00:04:47.650 Coast Guard and the entire panel still remains intact this 64 00:04:49.000 --> 00:04:51.280 ability of Marinite panels to serve 65 00:04:51.280 --> 00:04:55.720 as an effective barrier against the spread of fires has been demonstrated numerous 66 00:04:55.720 --> 00:04:56.720 times in 67 00:04:56.560 --> 00:05:01.380 actual service at sea one such instance involved the tanker Atlantic Dealer 68 00:05:01.380 --> 00:05:03.260 in collision with 69 00:05:03.260 --> 00:05:08.080 another vessel, the Atlantic Dealer's after deck quickly became a blazing inferno 70 00:05:08.080 --> 00:05:09.440 when burning crude 71 00:05:09.440 --> 00:05:15.100 oil was released on the surface of the water. Yet the Marinite panels used in her construction 72 00:05:15.600 --> 00:05:20.160 kept heat levels down so effectively that the ship's crew was able to fight the 73 00:05:20.160 --> 00:05:21.160 fire successfully. 74 00:05:21.300 --> 00:05:26.360 The blaze was confined and in less than an hour it was completely extinguished. 75 00:05:29.790 --> 00:05:30.790 Marinite's rugged 76 00:05:30.630 --> 00:05:34.310 resistance to abuse was severely put to the test in the liner America. 77 00:05:35.210 --> 00:05:36.210 Launched 78 00:05:35.850 --> 00:05:40.670 in 1938, the America was one of the first transatlantic liners to employ 79 00:05:40.670 --> 00:05:46.410 completely fire-safe construction. Her Marinite panels, used as bulkheads in 80 00:05:46.410 --> 00:05:50.450 many locations throughout the ship, were an important part of her fire-safe 81 00:05:50.450 --> 00:05:56.130 design. Later, when she was pressed into service as a troop carrier, the America 82 00:05:56.130 --> 00:06:00.430 transported hundreds of thousands of our troops and many tons of equipment to 83 00:06:00.430 --> 00:06:02.810 Europe, and these same Marinite panels 84 00:06:02.810 --> 00:06:05.790 were called upon to withstand four years 85 00:06:05.790 --> 00:06:07.390 of the hardest kind of abuse. 86 00:06:07.850 --> 00:06:10.250 They came through with flying colors. 87 00:06:11.910 --> 00:06:14.330 When the America was returned to peacetime service, 88 00:06:14.870 --> 00:06:16.930 her Marinite bulkheads were found 89 00:06:16.930 --> 00:06:18.450 to be in such excellent condition 90 00:06:18.450 --> 00:06:20.650 that very few replacements were needed. 91 00:06:22.650 --> 00:06:25.630 A look at the raw materials from which Marinite is made 92 00:06:25.630 --> 00:06:29.630 will help us understand why this modern joiner material can 93 00:06:29.630 --> 00:06:32.110 offer such an unusual combination of advantages. 94 00:06:33.010 --> 00:06:35.550 The basic raw materials are shown here, 95 00:06:36.610 --> 00:06:41.950 asbestos fibers, diatomaceous silica, and lime, 96 00:06:44.730 --> 00:06:47.310 three incombustible materials that have 97 00:06:47.310 --> 00:06:48.830 all the permanence of stone. 98 00:06:49.570 --> 00:06:52.910 But it is the strength of these amazing asbestos fibers, 99 00:06:53.190 --> 00:06:55.590 so soft and yielding to the touch, 100 00:06:55.990 --> 00:06:59.290 yet actually as strong as piano wire that 101 00:06:59.290 --> 00:07:01.050 contribute so much to the performance 102 00:07:01.050 --> 00:07:02.050 of the finished product. 103 00:07:03.050 --> 00:07:06.170 Countless numbers of these strong silk- like fibers 104 00:07:06.170 --> 00:07:10.070 are distributed uniformly throughout each Marinite panel, 105 00:07:10.370 --> 00:07:13.350 forming a reinforcement that adds greatly 106 00:07:13.350 --> 00:07:15.830 to its strength and ability to take punishment. 107 00:07:18.650 --> 00:07:22.150 In the manufacturing process, selected asbestos fibers 108 00:07:22.150 --> 00:07:24.490 and diatomaceous silica are combined 109 00:07:24.490 --> 00:07:27.090 with water and a suitable inorganic binder 110 00:07:27.090 --> 00:07:28.210 to form a slurry. 111 00:07:28.210 --> 00:07:33.490 This slurry is carried to a hydraulic press where the panels are formed 112 00:07:33.490 --> 00:07:34.490 under pressure 113 00:07:34.190 --> 00:07:39.610 into a tough, homogenous sheet of relatively low density and uniformly high strength. 114 00:07:40.550 --> 00:07:41.550 As 115 00:07:41.230 --> 00:07:46.070 the panels are formed, they are removed from the press bed by means of a suction lift. 116 00:07:46.810 --> 00:07:53.150 After curing and drying, the panels pass to a drum-type sander where a smooth surface 117 00:07:53.150 --> 00:07:57.550 finish is imparted and the thickness of the sheet is accurately controlled. 118 00:07:59.980 --> 00:08:05.000 Following the sanding operation, Marinite marine panels, which are to be further 119 00:08:05.000 --> 00:08:09.340 finished, are impregnated with an inorganic primer and again dried. 120 00:08:12.890 --> 00:08:13.890 The 121 00:08:13.510 --> 00:08:16.970 Marinite panels are then ready to receive one of the many decorative 122 00:08:16.970 --> 00:08:22.930 facings available, such as plastic, metal, or wood veneer, or they 123 00:08:22.930 --> 00:08:23.930 may be left 124 00:08:23.510 --> 00:08:26.790 unfaced to be painted after installation if desired. 125 00:08:28.900 --> 00:08:30.580 Let's go now to the Quincy 126 00:08:30.580 --> 00:08:34.740 Yard of the Bethlehem Steel Company Shipbuilding Division to understand how 127 00:08:34.740 --> 00:08:40.660 Marinite and other Johns-Manville fire safe joiner materials are used in modern 128 00:08:40.660 --> 00:08:45.500 fire safe ship construction. Here the Independence and her sister ship the 129 00:08:45.500 --> 00:08:51.220 Constitution are under construction. These are the Marinite panels that are 130 00:08:51.220 --> 00:08:55.100 soon to become an important part of the fire safe interior of the Independence. 131 00:08:55.740 --> 00:08:59.800 They were stacked here in the yard warehouse ready to be transferred as 132 00:08:59.800 --> 00:09:03.440 needed to the fabricating shop or to the ship's side. 133 00:09:05.100 --> 00:09:06.940 Because Marinite panels are 134 00:09:06.940 --> 00:09:11.660 available in a variety of sizes, only a minimum of cutting and fitting is 135 00:09:11.660 --> 00:09:16.880 usually required at the yard. When this is necessary, however, Marinite 136 00:09:16.880 --> 00:09:22.320 demonstrates its ready workability. It cuts easily and a relatively simple 137 00:09:22.320 --> 00:09:28.400 sawing arrangement does the job. This unit is of the skill saw type fitted 138 00:09:28.400 --> 00:09:33.080 with a silicon carbide cutting wheel. It's also equipped with a dust disposal 139 00:09:33.080 --> 00:09:36.860 system which is desirable when volume cutting is to be done. 140 00:09:39.500 --> 00:09:40.520 Modern decorative 141 00:09:40.520 --> 00:09:44.560 treatment frequently calls for a small bevel along the panel edges. 142 00:09:45.540 --> 00:09:46.540 Here a 143 00:09:46.520 --> 00:09:50.940 high-speed router, fitted with a Carboloy bit, is used for this purpose. 144 00:09:51.700 --> 00:09:55.880 A piece of angle is attached to the router base to provide alignment. 145 00:09:56.480 --> 00:10:01.500 When the unit is run along the edge of the panel, a smooth, accurate bevel results. 146 00:10:03.540 --> 00:10:06.420 After the marked panels have been cut and beveled, 147 00:10:06.440 --> 00:10:10.860 they're loaded on cargo trays and transported by trailers to the ship's side. 148 00:10:11.820 --> 00:10:15.100 There, they're picked up by an overhead crane and hoisted aboard. 149 00:10:16.640 --> 00:10:21.200 Let's follow these Marinite panels to their destination and observe the few remaining 150 00:10:21.200 --> 00:10:25.180 operations that are necessary to convert them into fire-safe bulkheads. 151 00:10:26.220 --> 00:10:31.760 The first step is the laying of deck channels and deckhead furring to form the boundaries 152 00:10:31.760 --> 00:10:32.760 of all spaces. 153 00:10:33.720 --> 00:10:39.080 Certain sizes of metal furring can be cut to exact size with a hand-lever operated channel 154 00:10:39.080 --> 00:10:40.860 shear of the type shown here. 155 00:10:41.220 --> 00:10:45.020 This gives a clean, square cut, free from burrs. 156 00:10:45.020 --> 00:10:50.440 With the deck channels and deck head furring in place, 157 00:10:50.660 --> 00:10:53.160 the posts for shell lining are erected, 158 00:10:53.240 --> 00:10:56.620 forming the steel framework which will receive the Marinite panels. 159 00:10:57.660 --> 00:10:59.680 To provide efficient thermal 160 00:10:59.680 --> 00:11:04.100 insulation, Johns-Manville BX Spintex insulation has been installed. 161 00:11:04.480 --> 00:11:06.380 This is a specially processed 162 00:11:06.380 --> 00:11:11.520 incombustible mineral wool designed to meet rigid Coast Guard and Maritime Administration 163 00:11:11.520 --> 00:11:16.940 requirements. In addition to its thermal insulating qualities, it has excellent 164 00:11:16.940 --> 00:11:22.820 noise absorption capacity. The insulation is secured in place by welding 165 00:11:22.820 --> 00:11:23.820 pins and 166 00:11:23.580 --> 00:11:28.560 clips. Now the cut and beveled Marinite panels are erected. 167 00:11:28.740 --> 00:11:30.480 Each panel is set in 168 00:11:30.480 --> 00:11:36.860 its proper location.

Here, Marinite offers a combination of light weight with 232 00:16:00.640 --> 00:16:04.420 strength, fire protection, and rugged resistance to abuse. 233 00:16:04.960 --> 00:16:05.980 In the normal 234 00:16:05.980 --> 00:16:11.400 thickness used, Marinite weighs less than three pounds per square foot, yet it has 235 00:16:11.400 --> 00:16:14.540 ample strength for use as a freestanding bulkhead. 236 00:16:15.600 --> 00:16:17.880 In ferries, as in cargo ships, 237 00:16:18.160 --> 00:16:22.660 bulkhead materials are called upon to withstand constant severe punishment. 238 00:16:22.660 --> 00:16:27.220 This Staten Island ferry is being built to take that kind of abuse. 239 00:16:27.560 --> 00:16:33.160 Her fire-safe Marinite bulkheads will require little or no maintenance through the years, 240 00:16:33.380 --> 00:16:36.280 yet they will contribute much to passenger comfort 241 00:16:36.280 --> 00:16:41.800 because Marinite also provides thermal insulation and helps to deaden noise. 242 00:16:43.380 --> 00:16:47.600 In tugboat service, Marinite offers another special advantage. 243 00:16:48.000 --> 00:16:51.580 Its low-density structure assures freedom from drumming, 244 00:16:51.580 --> 00:16:54.580 so often a problem in the cramped quarters aboard a tug. 245 00:16:55.550 --> 00:16:58.800 Here, too, Marinite provides effective noise damping. 246 00:16:59.060 --> 00:17:01.820 Although in areas where noise levels are high 247 00:17:01.820 --> 00:17:04.480 and the most efficient acoustical treatment is desirable, 248 00:17:05.100 --> 00:17:08.560 perforated marine acoustical units are usually recommended. 249 00:17:11.600 --> 00:17:14.130 No discussion of modern shipping would be complete 250 00:17:14.130 --> 00:17:16.190 without mentioning the United States, 251 00:17:16.390 --> 00:17:19.010 latest glamour girl of the United States Lines. 252 00:17:19.370 --> 00:17:21.770 Her top speed is a military secret, 253 00:17:21.770 --> 00:17:26.430 but it is no secret that she is probably the fastest transatlantic liner 254 00:17:26.430 --> 00:17:27.430 ever built. 255 00:17:27.470 --> 00:17:32.590 One reason for this is that special consideration was given to the selection of lightweight 256 00:17:32.590 --> 00:17:35.410 materials in the construction of this superliner. 257 00:17:36.730 --> 00:17:41.450 More than half a million square feet of Marinite were used to create the interiors 258 00:17:41.450 --> 00:17:42.450 in this 259 00:17:41.790 --> 00:17:42.790 great ship. 260 00:17:42.910 --> 00:17:47.030 Although as we've seen, the standard Marinite panels are comparatively light in 261 00:17:47.030 --> 00:17:48.030 weight for 262 00:17:47.530 --> 00:17:52.490 bulkhead materials, a special type of Marinite of even less density was supplied 263 00:17:52.490 --> 00:17:53.490 for the United 264 00:17:52.990 --> 00:17:59.230 States. A resultant lower displacement is an important factor contributing to her unprecedented 265 00:17:59.230 --> 00:18:04.430 speed. Today, as in the days of the famous clipper ships of a century ago, 266 00:18:04.850 --> 00:18:06.570 American ships stand as 267 00:18:06.570 --> 00:18:11.810 evidence of American ingenuity and ability to find a better way of doing things. 268 00:18:12.310 --> 00:18:13.570 American industry, 269 00:18:13.570 --> 00:18:18.730 working hand-in-hand with marine architects and engineers, strives constantly 270 00:18:19.110 --> 00:18:24.270 to supply products to make our ships safer, faster, more comfortable, 271 00:18:24.570 --> 00:18:25.670 more efficient. 272 00:18:26.230 --> 00:18:32.150 Johns-Manville, producer of Marinite, the fire-safe bulkhead material, is proud 273 00:18:32.150 --> 00:18:33.150 to play 274 00:18:32.690 --> 00:18:37.210 a part in helping to make these accomplishments possible for the ships of the 275 00:18:37.210 --> 00:18:38.250 American Merchant 276 00:18:38.250 --> 00:18:39.250 Marine.
