1 00:00:01,960 --> 00:00:07,240 Speaker 1: Welcome to brain Stuff production of iHeartRadio. Hey brain Stuff 2 00:00:07,280 --> 00:00:14,520 Speaker 1: Lauren Vogelbam here. Preparing for potential emergencies is stressful. For example, 3 00:00:14,760 --> 00:00:17,480 Speaker 1: it's really unlikely that you'll ever be in a car 4 00:00:17,520 --> 00:00:20,840 Speaker 1: accident that winds up with your vehicle being submerged in water. 5 00:00:21,920 --> 00:00:25,200 Speaker 1: For example, in the US, driving heavy country, it only 6 00:00:25,239 --> 00:00:28,080 Speaker 1: happens less than one thousand, five hundred times a year. 7 00:00:28,800 --> 00:00:31,840 Speaker 1: That's less than zero point zero three percent of car 8 00:00:31,880 --> 00:00:36,839 Speaker 1: accidents here. But as with all potential emergencies, having a 9 00:00:36,880 --> 00:00:39,920 Speaker 1: plan in place will help keep you calm and increase 10 00:00:39,960 --> 00:00:44,160 Speaker 1: your chances of getting yourself out. So if you drive 11 00:00:44,200 --> 00:00:46,640 Speaker 1: in areas with bodies of water or the risk of flooding, 12 00:00:46,920 --> 00:00:51,199 Speaker 1: it's worth going through the stressful planning process. The experts 13 00:00:51,200 --> 00:00:54,520 Speaker 1: of the American Automobile Association or Triple A a reckend 14 00:00:54,640 --> 00:00:57,959 Speaker 1: keeping in mind what they call the SURE method that 15 00:00:58,040 --> 00:01:02,000 Speaker 1: stands for stay calm, unbuckle or cut your seat belt, 16 00:01:02,400 --> 00:01:07,040 Speaker 1: roll down or break windows and exit quickly. Helping children first. 17 00:01:08,360 --> 00:01:11,360 Speaker 1: But let's back up a little. The problem with being 18 00:01:11,440 --> 00:01:15,039 Speaker 1: in a sinking car is that water is heavy. So 19 00:01:15,240 --> 00:01:17,480 Speaker 1: if your car is sinking, the pressure of all that 20 00:01:17,640 --> 00:01:19,720 Speaker 1: water on the outside of the car will prevent you 21 00:01:19,760 --> 00:01:22,600 Speaker 1: from opening the doors until the car's cabin fills with 22 00:01:22,640 --> 00:01:26,040 Speaker 1: water and the pressure equalizes. But you don't want to 23 00:01:26,080 --> 00:01:28,480 Speaker 1: wait for that if you don't have to, because breathing 24 00:01:28,560 --> 00:01:32,119 Speaker 1: is good. The best thing is to try to get 25 00:01:32,120 --> 00:01:35,360 Speaker 1: a window opens that you can escape through. There, cars 26 00:01:35,400 --> 00:01:38,480 Speaker 1: sink quickly. You may only have thirty seconds to a 27 00:01:38,560 --> 00:01:41,560 Speaker 1: minute before the water level reaches the passenger windows, so 28 00:01:41,720 --> 00:01:44,240 Speaker 1: you have to act fast. If you can roll a 29 00:01:44,240 --> 00:01:47,240 Speaker 1: window down, that's great, but it may bring you extra 30 00:01:47,280 --> 00:01:50,440 Speaker 1: piece of mind to store an emergency window breaking tool 31 00:01:50,520 --> 00:01:54,120 Speaker 1: in your car though. Back in twenty nineteen, the Triple 32 00:01:54,200 --> 00:01:56,440 Speaker 1: A ran a study about the different kinds of glass 33 00:01:56,480 --> 00:01:59,200 Speaker 1: being included in modern car designs and the ability of 34 00:01:59,240 --> 00:02:01,440 Speaker 1: different tools on the market to break them in case 35 00:02:01,480 --> 00:02:06,360 Speaker 1: of emergency. They overall recommend buying spring loaded style tools 36 00:02:06,520 --> 00:02:08,960 Speaker 1: because the hammer style tools they tried out sometimes broke 37 00:02:09,080 --> 00:02:12,360 Speaker 1: during the test. But their key finding was actually that 38 00:02:12,400 --> 00:02:17,000 Speaker 1: the type of glass your car contains matters the most. Traditionally, 39 00:02:17,120 --> 00:02:20,160 Speaker 1: car windows and rear windshields were made of tempered glass, 40 00:02:20,200 --> 00:02:22,959 Speaker 1: which is designed so that when it breaks, it shatters 41 00:02:22,960 --> 00:02:25,480 Speaker 1: into small chunks that are less likely to cut you 42 00:02:25,560 --> 00:02:29,080 Speaker 1: than normal glass shards. The type of glass in the 43 00:02:29,120 --> 00:02:34,400 Speaker 1: front windshield, meanwhile, is usually laminated glass E. Laminated glass 44 00:02:34,440 --> 00:02:38,040 Speaker 1: is made by sandwiching a layer of polyvinyl butterol between 45 00:02:38,120 --> 00:02:41,240 Speaker 1: two pieces of glass. The glass and the pv BE 46 00:02:41,560 --> 00:02:44,520 Speaker 1: are sealed by a series of pressure rollers and then heated. 47 00:02:45,440 --> 00:02:49,840 Speaker 1: This combination of pressure and heat chemically and mechanically bonds 48 00:02:49,880 --> 00:02:54,440 Speaker 1: the PVB to the glass. That inserted layer of polyvinyl 49 00:02:54,680 --> 00:02:57,720 Speaker 1: allows the glass to absorb energy during an impact and 50 00:02:57,880 --> 00:03:02,359 Speaker 1: gives the glass resistance to penetration from flying projectiles, meaning 51 00:03:02,440 --> 00:03:05,680 Speaker 1: that laminated glass can break and be punctured, but it 52 00:03:05,680 --> 00:03:09,400 Speaker 1: will stay intact because of its chemical bond with the polyvinyl. 53 00:03:09,960 --> 00:03:12,520 Speaker 1: It also deflects up to ninety five percent of ultraviolet 54 00:03:12,600 --> 00:03:15,080 Speaker 1: rays from the sun and helps deflect road noise and 55 00:03:15,160 --> 00:03:19,239 Speaker 1: help quiet down a vehicle's cabin, which is all great 56 00:03:19,480 --> 00:03:22,920 Speaker 1: at preventing flying objects from coming at you through the windshield. 57 00:03:23,280 --> 00:03:25,320 Speaker 1: Anyone who grew up with the Final Destination movies is 58 00:03:25,360 --> 00:03:28,840 Speaker 1: still traumatized from that and at preventing you from being 59 00:03:28,919 --> 00:03:31,680 Speaker 1: ejected out through the windshield in case of a sudden stop. 60 00:03:33,080 --> 00:03:36,440 Speaker 1: But it also means laminated glass can't be shattered by 61 00:03:36,560 --> 00:03:40,000 Speaker 1: escape tools, and an increasing number of new vehicles have 62 00:03:40,120 --> 00:03:43,440 Speaker 1: switched from using tempered side glass windows to laminated side 63 00:03:43,440 --> 00:03:47,320 Speaker 1: glass windows in response to federal safety standards A but 64 00:03:47,520 --> 00:03:51,600 Speaker 1: don't panic. Most new cars with laminated side windows include 65 00:03:51,800 --> 00:03:55,400 Speaker 1: one tempered side window. Stickers near the bottom of each 66 00:03:55,440 --> 00:03:57,320 Speaker 1: window should tell you what the glass is made of. 67 00:03:58,040 --> 00:03:59,960 Speaker 1: If there are no stickers there, you can check your 68 00:04:00,000 --> 00:04:03,320 Speaker 1: owner's manual or get in touch with the manufacturer. If 69 00:04:03,360 --> 00:04:06,240 Speaker 1: your side windows are all laminated glass, you'll know that 70 00:04:06,280 --> 00:04:09,760 Speaker 1: you'll have to roll one down as quickly as possible. Again, 71 00:04:09,880 --> 00:04:13,080 Speaker 1: it's most important to have a plan in place beforehand. 72 00:04:13,440 --> 00:04:15,440 Speaker 1: If you know you can break a window, have an 73 00:04:15,520 --> 00:04:18,040 Speaker 1: escape tool at the ready and know which window to break. 74 00:04:18,800 --> 00:04:21,839 Speaker 1: Just consider watching an online tutorial to familiarize yourself with 75 00:04:21,839 --> 00:04:24,400 Speaker 1: how the device works, and you can test your spring 76 00:04:24,400 --> 00:04:26,560 Speaker 1: loaded escape tool on a notepad or a piece of 77 00:04:26,600 --> 00:04:29,680 Speaker 1: spare wood. If it's working properly, you'll hear a click 78 00:04:29,800 --> 00:04:31,839 Speaker 1: and be able to see a hole or indent in 79 00:04:31,880 --> 00:04:34,919 Speaker 1: the paper or wood. Escape tools can also come in 80 00:04:34,960 --> 00:04:37,360 Speaker 1: handy in case your seat belt buckle gets jammed during 81 00:04:37,360 --> 00:04:40,279 Speaker 1: an accident. Look for tools that include a device for 82 00:04:40,400 --> 00:04:43,920 Speaker 1: safely and easily slicing through seat belts. You want to 83 00:04:43,920 --> 00:04:46,120 Speaker 1: get out of your seat belt before opening or breaking 84 00:04:46,120 --> 00:04:49,000 Speaker 1: a window because water can rush in very fast through 85 00:04:49,000 --> 00:04:54,760 Speaker 1: a window. Again, remember the sure method, Stay calm, unbuckle 86 00:04:54,800 --> 00:04:57,640 Speaker 1: your seat belt or cut it if it's jammed, Roll 87 00:04:57,680 --> 00:05:00,480 Speaker 1: down or break a window, and exit the vehicle quickly. 88 00:05:00,600 --> 00:05:04,679 Speaker 1: Helping children first, don't call nine one one until after 89 00:05:04,720 --> 00:05:08,520 Speaker 1: you've escaped, because cars again sink quickly. Time is of 90 00:05:08,560 --> 00:05:11,480 Speaker 1: the essence. If you can't get a window open, head 91 00:05:11,520 --> 00:05:14,280 Speaker 1: to the backseat of the car, where water will fill in. Last, 92 00:05:14,880 --> 00:05:16,600 Speaker 1: take a deep breath, and try to get a door 93 00:05:16,640 --> 00:05:20,719 Speaker 1: open once the pressure is equalized. It's scary to think 94 00:05:20,760 --> 00:05:22,880 Speaker 1: that you might need to prepare for an incident that 95 00:05:23,000 --> 00:05:26,000 Speaker 1: traps you in your car, but experts do agree that 96 00:05:26,040 --> 00:05:28,960 Speaker 1: it's better to acknowledge the possibility. If you have a 97 00:05:29,000 --> 00:05:31,120 Speaker 1: tool with an easy reach and you have some idea 98 00:05:31,120 --> 00:05:33,720 Speaker 1: of what to do, you'll save crucial seconds that could 99 00:05:33,800 --> 00:05:41,600 Speaker 1: make all the difference.
