ocean loving fun seekers the world over. commonly called the booze cruise because the price of i ticket includes unlimited alcohol and food. on the west coast of costa rica, one such party boat is about to depart for the island of tortuga. a lexus is one of more than 100 people piled on to this catamaran for the trip. it's a hot day and most of the passengers are on the top deck enjoying the shade of the canopy. but then less than 30 minutes into the trip, strong winds and waves force the fwoet turn back and the cruise issued an unspecified distress signal. >> about five minutes after they turned it the boat around, they start handing out life jackets. >> as long as there's still margaritas. >> all of a sudden, the boat's tilts. they say everybody run to this side of the boat. >> alexis continues recording as the vibe quickly turns to

confusion. >> i'm kind of staying in the middle and going okay, this is strange. >> and things are about to get a whole lot worse. >> oh, my god. >> suddenly, the boat makes a hard tilt. with only seconds before disaster, would you know what to do? the button you're on is leaning, taking on water. should you, a, help slower passengers off first so they don't become trapped? b, immediately dive into the ocean and swim away from the boat or c, find something sturdy and hold on for as long as you can. >> once water starts coming in over the tran some, over the stern of the boat, the boat's sinking. hanging onto the table ain't going to keep you bob water. if your world is upside down, you're going to die. >> if you chose c, you chose wrong but you got to do something and in this case, what might seem selfish could mean

survival. >> you're no help to anybody if you're drowning yourself. before you can help anybody else, you have to help yourself and make sure you're an asset and not a liability to someone. >> for that reason, a is the wrong decision. >> if you're barely hanging on for survival, that might be all you can do is just plop in the water and survive and try to find the surface. >> there was absolutely no time for me to even think about anything but the fact that i needed to swim and to get out and to get off of this boat. >> the correct answer is b, immediately dive in and swim away from the boat. but for alexis and 100 other tourists, it's too late to jump. as the vessel sinks, this woman fights to keep her children together. alexis struggles to break free as the boat floor bangs against her head. >> my biggest concern was being

sucked underneath the canopy. i thought to myself, i'm not dying today and i just swam. >> with her go pro camera still regarding, she escapes the wreck but the nightmare isn't over yet. >> by the time my head popped bob the water, the boat was gone. there were people and things floating in the water. there was no boat to be seen. >> now passengers are left clinging to wreckage, stranded in open ocean and facing a horrific reality. >> what? >> i think he's dead. >> no. >> the man in the water. exploding. > now what? your boat has capsized and you're stranded in open ocean. should you, a, swim for shore if you can see it. b, lose your waterlogged clothes so they don't weigh you down or c, stay with the wreckage. >> if somebody were to swim off

on their own, they could get off their target pretty easily by ocean currents and wind and waves. >> so even if you're an excellent swimmer, choosing a is a risky proposition. what about option b? >> we have everyone? >> true or false. your clothes can actually help you keep afloat. believe it or not, the answer is true. it's an old sailor's survival trick. if you lose your life jacket, tie the legs of your pants into a knot. fill them with air and wrap it around your head. since even those waterlogged clothes can function as a flotation device, b is the wrong decision. that makes your best chance at getting saved in this scenario option c. >> if the boat sinks, stay with the wreckage because that's what any search and rescue crew is going to see. they're going to see the wreckage and the boat. >> after more than an hour --

boats responding to the emergency distress signal arrive for the grateful survivors. >> i remember giving the guy a hug when i got back to land. i was going yes, you know, i'm on solid ground now. >> sadly three passengers lose their lives in the accident. a fate experts say you may be able to avoid with just a little planning. > it takes five seconds of thought just to be prepared for something. what you've done when you've done that is planted that seed in the back of your head that something could go wrong. when it goes wrong, you react to it. >> if the worst does happen and your boat capsizes experts urge you to follow these tips. jump away from the sinking boat. stay with the wreckage so rescuers can find you and most importantly, be prepared for the worst before it happens. >> if you're not prepared for it, if you're not trained for it, have you no choice but to panic. >> oh, my god.

fresh air until that vehicle is actually overcome by smoke and fire snir and making a run for it isn't much better. >> you should not flee and foot. you most likely would be safer in a structure that would protect you for a matter of moments rather than being in the direct line of the wildfire. that fire front will move over you very rapidly and you have a better chance of survivability by putting yourself inside of a structure. >> the correct answer is b. but if no structure is available, there's another option. >> the best sort of escape in an inescapable environment in a vehicle is find an open area that has low fuel, that has some dirt around it that does not have something that will burn. you certainly want to try to stay away from any trees. try to get yourself as low to the ground as you possibly can. and hopefully that fire front will be pass and we'll be able to survive it. >> hope that she makes it out. >> in the chaos, eric and his brother lose contact with their family.

>> you really shouldn't coverny vehicle with window coverings due to the fact those are combustible tiers and those materials itself will start to catch fire based on their radiated heat. >> and rolling down your windows will only let the elements in faster. if you chose b, you made the correct decision. keep those windows closed. >> what you want to do is try to stay encapsulated inside that vehicle as best as you possibly can. it's imperative you ensure that your windows are fully close toed chavisability is fully maintained. you need to slow down as best as you can and ensure that you have space between you and possibly another vehicle in front of you. >> after losing track of their relatives, eric and his brother barely make it through the firestorm. escaping their car just seconds before it's engulfed in flames. turns out their mother is nearby and witnesses their escape from the vehicle. >> what i see is the kids, you

know, with the car burning. i was panicking. i was shaking. for the whole you know commotion that was happening. but just to think of i'm going to lose them, i was feeling numb but i got out and run to them. >> eric and his extended family make it out but his grandmother's house is totally destroyed along with 60% of middletown's other homes. in the end, several firefighters suffered severe burns. and four civilians lost their lives. >> i do think it's a miracle that we survived. it was the scariest thing of my life and always will be that nothing can top that. >> to avoid finding yourself in such a dire scenario, it's critical to always listen for evacuation orders and remember the following survival tips -- if driving, keep headlights and hazard lights on and close your windows. if trapped, find a structure to take cover inside or find an

open area and lay down. avoid fleeing a wildfire on foot. it will be moving too fast. as climate change causes drought stricken areas to increase across the u.s., natural disasters like the middletown blaze could become more common. remembering these tips may be your key to staying cool under fire. >> go, go. the department of justice reports about 3 million home burglaries every year. some criminals will wait for you to leave for work, then rob your house in broad daylight as demonstrated in this video. others are bold enough to strike even when you're at home. and that's when things can get really dangerous. >> sometimes you're going to make that split second decision to either fight that person or to get away from that person. >> this woman decides to fight. she grabs her own weapon and fires at the intruders.

flash floods are one of nature's most terrifying and unpredictable phenomena. massive surges of water rushing down canyons can turn small creeks into raging rivers. and city streets into the swirling death traps. >> well, the most vulnerable

drain is one where water's coming out of a canyon and if you have a thunder cloud pour all kinds of water into a narrow canyon, the walls cause the water level to be higher. and when that comes out of that canyon, if there's a road going in front of it, all of a sudden some unsuspecting is motorist is hit by a flood of several feet of water which is going to be fatal in many cases. >> [ bleep ]. >> on average, 127 people die in flash and river floods each year in the u.s. alone. and according to the national weather service, about half of those fatalities involve vehicles. >> for some reason, moving water attracts people and they think well, i'm in a big heavy two or three-town vehicle and sick drive across this and they get fooled. >> in austin, texas, 30-year-old carrie pack ser driving home during a midday storm when his car is swept up by a flash flood. >> it was raining intensely. and so it was extremely

off your feet. >> most everybody's been in the ocean and they've been pounded bid a huge wave and they feel that force. they can't get up until the water recedes. moving water a river or stream or flood-control channel does not give you that relief. it never relations so that force is constantly on you and you can't get up. that's where most of your drownings occur. >> you're trapped in your car and being carried away in a flash flood. what should be your first mof? a, unbuckle your seat belt and open the windows. b, push open the door and swim away from the car or c, keep the windows rolled up and stay with the car? >> you're not going to be able to push the door open against that weight of that water. remember how heavy that water is. remember it's an incompressible fluid. it doesn't just push aside like you do the air when you open the door. so that door is pretty much going to be staying closed. >> which makes b an impossible decision. and staying with the car is no

better. >> the car's beak a death trap. if you've rolled the windows down so the water's going to come in at some point. the only way to get out is going out through that window at some point. that's your trick. how do you get free of the car before the car is no longer a nice floating boat. >> i've called 911. they told me to roll down my windows. hopefully they'll be here soon. >> though it may seem counter intuitive it, the answer is a. unbuckle your seat belt and open your windows. but now, you have another split second decision to make. after several minutes, your car is filling with water through the windows and air vents. you're beginning to sink. should you, a, exit the car through the window and start swimming, b, climb onto the roof of the car, or c, grab on to a tree or passing structure through the open window? >> if i was going to get into floodwater, that's completely unpredictable. there's obstacles, dead trees,

fences, whatever it may be under that water that you can't see that if i were to try to swim, i was probably going to die. >> even if he's the best of swimmers it doesn't matter. that water is very, very dangerous and even challenging for the experts and the people like us that train in it all the time. >> as with swimming, climbing on the roof could also be dangerous. you could shift the weight and tip the whole car over. or it could roll naturally. either way, you're trapped. >> oh, my god. oh, my god. >> the answer is c. grab on to a tree or passing structure through the open window. >> is there something you can grab? is there a post nearby that you could reach out and grab or if the car floats over against a wall or something, be prepared to spring out the window and grab on to that wall. you have to split second thinking here. you've got get out of that situation. you need to climb to safety. but what are you going to grab hold of?

called 911, and after five hours, shivering in the tree, he was rescued by helicopter. he was lucky. >> you know when people are use the to driving a certain road and in this day and age we're always busy. you've got here and there. i'm used to driving that road. you see a little bit of water on that road. and you don't give it enough respect. water has more power than most people realize. the saying turn around, don't drown, i hope everybody's already heard that one but please don't just hear it. put it in your mind. >> here i am, i faneuil found my car. about two weeks after the accident, once the floodwaters had completely receded, i hiked out to the area. my car was still there laying on its side. and it's just completely demolished. >> this is the tree that saved my life. >> actually, when i was up in that tree, saved some of the seeds from the tree in my

pocket. and have i those at home ready 0 plant when i find the right place. >> i was all the way at the very top. if you encounter fast-moving flood awards, take note of the following split second tips. open your windows. at first opportunity, climb out of your window top safety. but first and foremost, never try to walk, swim or drive through floodwater. turn around. don't drown. by following these rules, you can save lives including your own when facing a flash flood. >> my god. >> look at this. oh, my god. terror at 50 feet. >> you can feel the heat. >> and later, the hazards of batteries overheating.

anniversary of the deadly attack in paris. the bataclan concert hall where dozens can of people were killed reopened saturday with a performance by sting. 130 people died in the series of attacks last year across paris. meanwhile, back in the u.s., thousands of people continue protesting president elect trump. in front of the white house, trump's soon to be residence, people gathered for a vigil to promote solidarity. now back to "split second decision." almost half a million fires ignite each year in u.s. buildings. that's according to the national fire protection association. it's an average of one fire every minute of every day. in houston, texas, fire breaks out at a five-story apartment complex under construction. a worker climbs the roof to investigate. but by then, the fire is too big to extinguish and it gets worse.

the worker tries to find his way down but ends up trapped here on this balcony. >> this guy is on the ledge. oh, look at this. oh, my god. >> you can feel the heat. >> and if they can feel it across the street, he can definitely feel it on the balcony. >> there is a period of time where if the room becomes consumed with hot heat that absolutely you can breathe that air in and it can actually burn your lung tissues as it's going down. >> with every passing second recent the temperature rises and the danger grows. >> oh, oh, my jesus. oh, my god. >> this construction worker is minutes from burning to death. he needs to make a decision and he needs to make it now. could you handle the heat? you're trapped by fire and smoke on the upper floor of a building. what's your first move? should you, a, try to crawl back

through the building staying low to the ground? b, call 911 and sit tight until help arrives or do you c, jump for it? aim for a tree, bush or something else that will cushion the fall? >> what we find is that a lot of civilians that are caught in these types of environments make poor decisions. instead of finding or understanding their environment and having a preplanned escape route, they usually will either go back to where the fire is or get caught in an area where the fire will soon consume. >> as for jumping, he's five stories up with only concrete below. >> there are survivalable falls at the fifth floor and there are nonsurvivable falls on the fifth floor depending on the individual and how you land, what you land on. >> in this case, even if you suspect someone else has already called for you, the correct saens b. sit tight and call 911. but you're not out of danger

yet. firefighters are coming but you need to make a decision before they arrive. what should you do? a, lower yourself to another floor of the building from a window, door oracle connie, b, get on your stomach and lay low, or c, cover your mouth and any exposed skin to protect yourself from smoke and flames. >> you have to imagine yourself cooking at home and opening your oven and most people cook about 350 degrees. you figure a fire anywhere from 700 to 800 to 1,000 degrees. >> true or false, flames can burn skin out even making contact. the answer is true. even if the actual flames never touch you, prolonged exposure to extreme heat is enough to scorch skin even through your clothes. >> it becomes what we call thermal burns and due to the heat of that fire, your skin could start burning. you could start developing redness based on the heat to a

point where your skin starts to blister. >> so while experts say you should drop to the floor and cover your skin if you're initially trap in the a fire, those decisions aren't effective when time is running out. >> dropping to his belly really wouldn't buy him much more time. however, what you can do is as low as you get, you always have moments of a little more safety than you would if you were standing up. >> the correct answer is a. if you can, lower yourself to another floor. with only seconds left before the fire reaches him, the construction worker makes the split second decision to drop from the fifth floor to the fourth floor. >> oh, no, oh, no, oh, no. >> oh. >> he had the ability and the agility to make that decision and was lucky enough to be able to land on that lower landing. obviously, not everybody's going to be able to do that. >> back up. >> he buys himself more time but not much. the fire captain frantically waves his arms and motions for

the driver to close the distance between the balcony and the ladder. >> lowering himself to the balcony below is buying him some time. just minutes. what you also have to compromise his safety is not only the fire consuming the floor that he's on but also the structural integrity of that building. >> sensing the lad ser already strained the fireman tells his partner to get back. >> back up! >> then with a good two-feet left -- >> the stress he's putting on that ladder if he jumps and that ladder happens to bounce up and down at the tip of that ladder has a significant risk of ladder failure which will jeopardize,'s life. >> yes. >> oh, thank jesus. thank you, god. >> they appear safe but it's not over yet. just as the engine driver swings the ladder wide -- >> look out!

>> oh, no, my god. >> the top floor collapses missing both the rescuer and the rescued by inches. the construction worker survives with second degree burns and a sprained ankle. thankfully, no one else was injured. if you're trapped by fire, our experts want you to remember these tips. call 911 and tell them your exactly location. don't assume someone else did it for you. never head back into the fire. get low to the ground and cover exposed skin. watch for falling debris. if you don't want to become a statistic, plan ahead. and stay alive. >> oh, no, my god! a driver starts to drift. >> no, back up now! >> and you're about to become collateral damage. muffet sat on a tuffet eating her curds and whey.
