stay safe and protect your body! this is korea's center of safety! safety first! we have some very special guests with us today. they've come together after 15 years. it's turbo's kim jeongnam and mikey. i heard the album. i like your song. - i heard you listen to it every day. / - that's right. because of that song, the homemakers and

stay-at-home moms all suddenly want to hit the nightclub. - that's pretty interesting. / - it's fascinating. how does it feel working together after a long hiatus? excuse me, kim jeongnam, but can't you just wear the glasses or the goggles, not both? no one recognizes him without the goggles. when i first started turbo... i always wore sunglasses.

i was thinking of wearing them today... but people might not recognize me then. no one's recognized him for 18 years. please recognize me now. he's desperate for attention. how are you these days? i can't sleep. - from the joy? / - because you're excited? it takes over an hour to listen to all 17 songs.

i listen to the album around 10 times a day. - you like it that much? / - i like it that much. mikey can't relate at all. i heard mikey would be here today... but why is kong hyungjin sitting there? - it's kong hyungjin. / - they look alike. they really look alike. i was going to wear sunglasses too... but no one recognizes me.

so since we have our album out... i hope people will recognize me now. i think we need to introduce our two guests. i've got their safety profiles right here. this is kim jeongnam's safety profile. 1995, exactly 21 years ago. it's been 21 years now. 21 years ago he joined vocalist kim jongkook and debuted as turbo's rapper.

their heyday was with their 1st and 2nd albums. but then he suddenly left the group. then after 18 long years of struggling... he made his comeback with the 3-member turbo, 20 years after his debut, and said good-bye to all of his struggles. (a new heyday awaits for turbo) next is mikey's safety profile. name: mikey.

the second rapper for turbo from the 3rd album to the 5th album. he created countless hit songs and tasted success. however in 2001, the group officially disbands and struggles follow. but he faced his struggles and returned to america... was that pansori? hear, hear! i was about to say that.

pansori... from working at a clothes store to selling insurance. really? it means his life turned around. hear, hear. he kept working different jobs to face his struggles. then returned to the 3-member turbo in 2015. and now, 20 years after his debut, he's escaped his troubles with unchanging fame.

- thank you. / - it's no joke. he sold insurance to the americans. he was a top seller. to the americans... was there an extreme job that you remember? i had countless jobs. i did manual labor at first... then i worked at a video store and clothing store... normally you'd do that before you become a singer.

video store... - ice cream shop. / - ice cream shop! after working all those jobs, did you still want to perform on stage? every day. every day? serious, i always had it. there was nothing else i could really do. - besides being a singer? / - right.

since i started my first job as a singer... there was nothing i could write on my resume. so after we disbanded, i had nothing else to do so i went back and learned insurance from a cousin. i got my certificate... i hated it at first. it really didn't suit me. it's beyond what you'd imagine. but how were you so good at it?

i tried this and that but that was the only qualification i had. since it's your profession. that's why... how does it feel to be here on safety first with jongkook and being on tv again? for me it's fascinating. that he's sitting here. you know he's been here a long time, right?

i find that even more fascinating. i'm going to be here for a very long time. let's meet the final member of turbo. jung taeho. taeho, can you lower your goggles? - like this? / - yes! - so handsome. / - it's turbo. dressed like that, it feels like we're at a ski resort today.

back in the day, skiing and turbo went hand in hand. they still play turbo songs on ski slopes. - you remember that song, right? / - of course. 'look up, white snow is falling' (heard hundreds of times on the ski slopes) nice. you're a good singer. you are. we're turbo.

he's a singer. people forget that i'm a singer. i thought he was an mc that sings well. jeongnam, you were injured badly on the slopes. i fell forward while skiing. i tore my philtrum. other people would've been injured elsewhere but he has such a long philtrum... he's going to live as long as a turtle.

it's fortunate that you didn't break your nose. they said i couldn't wear makeup after that injury. that's why i wore a mask for "black cat nero." he wore a mask midway... i thought it was his fashion. we thought that was his concept. on that same day i got frostbite on both ears. so for "black cat nero" i wore a beanie. to cover my ears.

(when they used to perform this song...) (they did it with beanie and mask) that's why i wore that. i had bandages covering my ears. and we wore beanies to copy them. now we finally know the truth. we've started talking about the dangers of ski slopes. so for today's first segment, we've prepared things related to ski slope safety.

6 million people go skiing each year. and each year around 10,000 people are injured on the slopes. there are things you must keep in mind to stay safe. that's why we prepared this. ski resort safety by numbers. what is the safe distance to keep between the skier in front of you? as you ski, you may realize you need to stop

but still get into an accident. that's because sometimes you can't always stop when you want to. how many meters is the safe distance for skiing? we'll do a test. this is how we will conduct the test. beginner, intermediate and advanced. we'll have 3 skiers of these skills take the test on their respective slopes.

as the experiment participant is skiing down... the safety man will suddenly lift his flag. we'll measure the distance it takes for the skier to come to a complete stop. the beginner skier is waiting at the top of the slope. we'll begin the experiment. go! (she skis down with the start signal) they all ski down at different speeds.

the safety man lifts the flag. the skier puts on the brakes. she slides down for a long time. she finally comes to a complete stop. let's watch again. in order to come to a complete stop. it took 5.03 seconds. now the intermediate skier. she begins.

the intermediate is a higher slope. as the safety man lifts the flag, she puts on the brakes. how long did she take? in order to come to a complete stop, she took 4.02 seconds. there's not too much difference. a very difficult course. finally the expert skier waits on top of the slope.

these people are good skiers. she skies down the slope with speed. look at that downhill. she's going really fast. she's disappeared. she creates a blizzard as she brakes. how long did she take to come to a complete stop? since she's going quite fast... the time for the expert to completely stop...

4.12 seconds. the time to stop for skiers... 5 seconds for the beginner. the intermediate and expert were 5 seconds. there wasn't too much difference between the three. it was an average of 5 seconds. even the expert skier took that long to stop because she's coming down at a fast speed. that means regardless of skill,

you need 5 seconds to come to a stop. how far did each skier slide as they braked? 14m for the beginner. 18m for the intermediate. the expert skier drifted 27m. the higher your skill level in skiing, you travel faster and so it takes longer to come to a stop. that means you need to keep at least

a 30m distance to ski safely. the ultraviolet rays on the slopes is 4 times stronger than in summer? soil and asphalt absorbs most of the uv rays. but on the snow or ice, 80% is reflected and hits our skin. if you just look at mountaineers that climb the highest of mountains... you can see the power of the uv rays.

that's why they're always burnt black. we interviewed some people who ski all day long as soon as the ski slopes open while being scorched by the uv rays. there's a kid. let's check the condition of their skin. they don't look good at all. compared to the area covered by goggles, the tip of her nose and her cheeks

are clearly darker. we measured the moisture and oil levels in the face of a woman in her 20s that works indoors all day. (oil +3, moisture +5) then what about these skiers? first, a man in his 40s that's been skiing every day for the past month. both moisture and oil levels are -4.

what about this 27-year-old woman who skis every weekend? moisture is -3, oil is -4. the 20-year-old girl that's been skiing for a week. then what about this teen that's just started skiing with the start of the holidays? both moisture and oil levels were -4. they were all from different age groups but their skin condition is similar.

just how bad is their skin? their skin is very dry. and because it's exposed to the cold for extended periods of time, they have a high excess of red spots. don't you wear sunscreen? i know that the uv rays are dangerous but i have a habit of not using sunscreen. when i go indoors my skin does sting a lot.

i do wear sunscreen but when i wake up the next day, my skin is red. when it's the off season, my face is burnt and it does affect daily life. the level of uv rays in summer is on average 12.17 milliwatts per cmâ². the uv rays reflected by the snow... 48 milliwatts per cmâ². 1 hour of skiing is the same as

being out in the summer sun for 4 hours. the same amount of uv rays strike the skin. there are many instances when people get sunburnt while skiing but don't realize it. why is that the case? after going to the slopes in winter, quite a lot of people come to the hospital from sunburn. since it's cold on the slopes,

the sensory nerves in the skin can become paralyzed and it becomes difficult to know that you're burnt. and if you sweat a lot on your skin, you absorb uv rays even faster. so more amounts of uv rays are absorbed. you should put sunscreen on the exposed parts of your face every 2 hours. this is the way to prevent sunburn on the slopes. what time of day do most ski accidents occur?

after 3 o'clock. according to statistics, most accidents occur between 3 p.m. and 5 p.m. we observed the slopes at 3 p.m. so many people on skis and snowboards. can you see the clear difference between 10 a.m. and 3 p.m.? at 10 a.m. the average distance between people... they maintain a safe distance.

(5.6m on average) then what about at 3 a.m.? it's normally like that. (average 3.4m ) with less distance kept between skiers, more accidents were occurring. however. something we realized while watching the skiers at 3 p.m.

there were many people falling over. they fall and slip. it must really hurt. why did you suddenly fall over? i lost my balance. because it's slippery. since more people ski over it, it melts the paths. so you say the slope is slippery?

are the slopes really more slippery at 10 a.m. instead of 3 a.m.? we did an experiment. we marked out equal spaces and the skier came down in zig zags. we set up the same course at 10 a.m. and 3 a.m. this is the slope at 10 a.m. he finally skis down. he slides down smoothly.

just like that. now it's 3 p.m. it's the same slope. he'll ski on it again. he's skiing down. he seems different to the morning. he seems like he's sliding out with his turns. anyway, he's finished. the time difference between the two runs... let's check them out at the same time.

- he's making big turns. / - you're right. the man on the left seems good. at 10 a.m. he finished in 12 seconds. at 3 p.m. it took him 18 seconds. why were you slower in the afternoon? if you ski at 10 a.m., the surface was really safe and nice. but by afternoon, the snow melts and gets slippery

because of the sun. so it was tough for me. if you check the slope at 10 a.m. and 3 p.m., the 10 a.m. slope has fine and soft snow. but at 3 a.m. the grains are clumped together and they look uneven. 3 hours before 2 p.m. and 3 hours after 4 p.m., the surface is exposed to the sun and the slope is slippery and not as good.

therefore, beginners should avoid 3 hours before and after these times when skiing. prepare for a collision when you fall over on the slope. if you go skiing or snowboarding on the slope, even the best of us will fall over and get into an accident. when skiers fall over the tip of the ski digs into the snow, bending the leg.

the legs and knees are the most common injuries. for snowboarders falling over, they fall on their hands so they injure their arms and shoulders the most. falling over by yourself on the slopes makes up for 80% of accidents when skiing. it's the most common accident. the next most common accident is skiers knocking into each other.

crashing is the most dangerous. if someone falls over and stays on the ground, skiers coming from behind can crash into them and cause a second accident. we met someone who's experienced this. i was turning to avoid another person. but i didn't see the person on the ground. and i ended up crashing into them. while avoiding other skiers and

coming down at a fast pace... he crashed into another skier resting on the slope. i fractured the tip of my left elbow and the person on the ground injured their hips. they needed treatment for a very long time. i feel so regretful that it happened. what is the most important gear needed for safety on the ski slopes as chosen by experts? the most important safety gear chosen by experts.

what could it be? i think it might be goggles. when i was a beginner at skiing... i went to practice at night. a woman was downhill skiing and crashed into me. her skis grazed my goggles. so if wasn't wearing goggles that night, i may have lost my eyesight. so i think it might be the goggles.

i had a similar experience. too much snow went in so i took off my gloves. i thought i was good enough and kept my hands in my pockets. - that's dangerous. / - you were being a fool. i was being a fool. as i came down, my hand got scratched on the skis of someone sitting down. - that's dangerous. / - so i think it could be gloves.

i think gloves are important. what else might be there? i think it'd be the safety helmet. safety helmet? you become strange if you injure your head. it's dangerous. yes, it's dangerous. but people think about their fashion first so they wear beanies and fur caps

but they don't wear helmets. most people ski like mikey. - just like him. / - that's the standard fashion. they don't even wear the goggles. it looks cooler if you wear them. try them on. (handsome skier) i think it might be a cell phone. i was about to say that too.

cell phone? i slipped like this once and was knocked outside of the safety fence. i didn't get injured but no matter how much i shouted, no one could hear me. you can get isolated like that. - isolated on the slopes. / - you need your phone. you might need it when you're in a dangerous spot or you might need it for romance too.

you don't want to ski down all the way for your phone. that'd be tough. you need it in that moment. you're different since you have experience. how were you rescued? i kept shouting. then someone on the ski lift saw me. a few people saw me... but they thought i was greeting them.

yeah, they shake their hands. they're just greeting you. "no, i'm not greeting you." that's how a safety guard rescued me. that's a relief. the most necessary safety gear for skiing. we asked 5 experts for their opinions. the most important safety equipment needed for skiing is...

the safety gear you must have for skiing is the helmet. you must put on your helmet. as chosen by experts is the helmet. we heard from mogul ski national representative, choi jaewoo. why is the helmet most important? if you fall over while skiing, you can often experience shock to your head.

when you can't control your body, you could crash into a fence. you could crash into other skiers. that will all cause shock to your head. that's why wearing a helmet is the safest way. the most important thing for safety is your helmet. how many skiers will be wearing helmets? a queue of people waiting to get on the lift. you can see that there's hardly anyone with a helmet.

there are many people on the slopes without helmets. why aren't you wearing a helmet? it's become a habit. when i wear a helmet, my movements become unnatural. it's hard to see and it's uncomfortable. i thought looking pretty was more important. (many reasons for not wearing helmets) let's count exactly how many people are wearing helmets.

they'd look cooler with helmets. they'd seem like experts too. they'd look like pros. there are many more people without helmets now. (1,435 people observed, 750 didn't have helmets) it's about half. 80% of injuries that endanger lives are caused by not wearing helmets. head trauma is the cause.

cerebral hemorrhaging or skull fracturing included. in these cases, you can die even before you reach the hospital. it's a very serious injury. will you ski safely? or will you put your life in danger? the choice is yours. the most important safety gear as chosen by the experts was the helmet.

how do you feel after seeing this? with children, the parents are obligated to put helmets on them. i think more adults might forget to wear them. that's right. forget trying to look cool. if you injure your head, that could endanger your life. please make sure you use helmets. it's definitely important.

you've mentioned it already but if you injure your head, it can affect a lot of your body. that is the most dangerous injury. the most important thing is not to be careless but thinking, i'll be okay this time. if you go skiing, please pack your helmets. let's find out what the next danger is. we visit a kbs waiting room to meet today's safety first guest.

she looks shy from behind. delicate hands... who is this very feminine lady? i think i know. please... hello. i'm safety first guest, lee suji. the reason why i'm the guest today... it's because of static electricity.

well, sometimes i do feel electric because of all the stares from the guys. but i'm here because of static electricity which really gives me goosebumps. let's find out how to protect ourselves from static electricity with suji. the moment when you have static electricity... step 1. when you grab the door knob.

that stings. that's right. this round knob. you get plenty of static from this. so i always stress whether to touch it or not. can you grab it now? now? pull the sleeve over your hand. ouch! there's nothing yet.

- she defeated the static. / - that's a relief. we'd better create some static. you want to create static? is that possible? who are these guys? what are you doing? the safety men appear with plastic rods and synthetic fabrics. where are you from?

are they going to beat her? after rubbing the rods... they place them on suji's index fingers. goodness. that must sting. this may look strange but we're passing the static from the rods into suji's body. has the static collected in suji's body?

we'll check by placing balloons on her head. - it sticks. / - they've stuck! the static flowing through her body has glued the balloons to her hair. she's going to grab the door knob again. the director is really making me suffer. you can hear the zapping, right? the instant she touches the door knob... you can actually hear the zapping.

how can we avoid the static in these situations? before you grab the door knob, touch the door first. touch the door with one hand. then grab the door knob with my other hand? that must eliminate the static. will it work? static won't flow through the wood... hey, there's no static!

i felt no static. if you touch the door while touching the door knob, there was no static shock. what happened? we'll check once again with the safety man. on this strange looking headband... we've attached thin polyethylene threads. if you wear this, you can tell whether static is flowing through your body.

just as we did with suji, we took plastic rods and rubbed them with synthetic materials and placed them on the safety man's index fingers. the more we did it, the higher the thin thread started to rise. this means static has accumulated in his body. that must be a lot of static. if he grabs the door knob first... you can see the static shock him with a loud sound.

this time, he'll touch the door with one hand and then grab the door knob. the moment he places his hand on the door... the thin thread falls straight down. now he grabs the door knob. but there's no static. how is this possible? static electricity is, as the name suggests, static. it's generally created through friction.

when there's too much static electricity, and the appropriate medium comes in range... the static moves instantly with a spark. when it moves out of the body through the fingers, you can feel the shock. but if you touch something made of wood first, you establish a ground connection and the electrons stored in your body escape. you become instantly discharged

through your fingertips, preventing the spark and the shock. step 2. when you get out of the car. you get that shock in your hands when you grab the car door handle. the outside handles are a given... and it also happens when you grab it on the inside. that always happens to me.

when this happens, you should tap the handle with your car key. we'll confirm again through an experiment. the moment he touches the handle... he gets a static shock. the static index is 1,400 volts. he taps the handle with the car key. we checked the index again. it's zero volts! all the static has disappeared.

he grabs the handle and there's no shock. the moment you touch the handle with the key, the static inside the handle is released through the key. the car key sucked it up. when you take off your clothes after being out. everyone has experienced this at least once. step 3. when you take off your clothes.

that's right! you hear those cracking noises when you take your clothes off. just thinking about it gives me goosebumps. your entire body stings. your hair floats into the air. i think it's worse for women because of their hair. what's going on? why are you here again? the safety men are back.

they start to gather static in suji's body. it's static. i'm not being tortured right now, am i? (this is a safe experiment) seeing as the balloons stick to her head... there seems to be plenty of static in her body. she's become cute again. i'll take off my sweater now. the result?

oh, that hurts! oh, no. did you hear the static. the moment suji takes off her sweater... she gets a static shock with a loud zap. we place the static measuring device to get an accurate measure. there are 6,200 volts in her sweater. how can we escape from static electricity

when we take off our clothes? you just have to change the order of clothes you take off. take your socks off first. so i just have to take my socks off first? normally you take your top off first not the other way around. will this really work? you guys again?

suji gathers static once again. (resolute) i'll take my socks off first. i'm still nervous. let's see if there's really no static. i'm shaking. i'll take off my sweater... suji removes her sweater after she's removed her socks.

has the static been removed? i can't hear anything. there was no zapping noises. this is fascinating. the inside of the sweater measures at 400 volts. that's 5,800 volts less than when she first took it off. let's confirm again with the safety man. we charge up the static in his body with plastic rods and synthetic fabrics.

the thread on the headband is standing on end. he's going to take off his sweater now. the moment he does... the thread above his head is still standing tall. they build up more static. this time he'll take off his socks first. the moment his bare feet touch the ground... the thread on his head flops down. seeing it again is still fascinating.

the difference between taking off his sweater first and taking off his socks first... what is the reason for this? socks are usually made with synthetic fabrics. that prevents the body from neutralizing the static and keeps the static inside of the body. but once you take off your socks and your bare feet touch the ground, the static can escape through your connection

to the ground. step 4. when you brush your hair. look at this. the static gets worse when i brush my hair. i'm sure the women can relate to this. it gets worse when you take your top off. what should you do in this situation? the answer is inside this box.

in this box? coat hangers? the way to eliminate static when you brush your hair... all you need is a metal coat hanger? the method is very simple too? so i just have to rub my hair with this hanger? then i'll brush my hair as i usually do... won't that cause more static?

the static is building up, right? then if you rub your hair with this hanger... when i put the brush there again... no static! there's no static. wow, this coat hanger is great. the effectiveness of the coat hanger... let's check it again. this time we'll try out the experiment on a girl with long straight hair.

now she'll rub the metal coat hanger on her hair... the thread falls down whenever she rubs the coat hanger on them. why does this happen? if wood is a non-conductor of electricity, metal coat hangers are the opposite so they provide a way for the electrons to escape. that's why the static is removed from your body. did you get that, everyone?

this is how you can prevent static throughout winter. - cut. / - good work. good work, safety men. good work on creating static. step 5. when you shake hands. it's really embarrassing when that happens. before you shake hands, blow your breath onto your hands.

blow my breath on my hands before i shake them? like this? will this simple action remove static in your hands? we'll find out with the safety man. static is stored in the safety man. the thread on his hair rises. when you shake hands in this situation... you're guaranteed to get a static shock. now he'll blow on his hands.

the more he blows, the thread keeps falling down. did you see it? now when he shakes hands... there is no static whatsoever. when it gets humid, the electrons are neutralized through the tiny water bubbles in the air. that prevents static from accumulating in the body. that is why blowing on your dry hands

to raise the humidity can be a reliable way to remove static. touching a coin in your pocket before you shake hands is also effective. the instant he touches the 10 won coin... the thread dies down. it also works with the 100 won coin. and even with the 500 won coin. coins are made of metals including copper

so by conducting the electricity into the coins, you can prevent static shocks. the electrons are released into the coins. how to save yourself from static shock. how was it? make sure to remember these steps and never get shocked again this winter. it's not like static can kill you, it's not that dangerous.

but it is really annoying. we learned how to get rid of static. if you have any tips like this please contact us on safety first. we keep our windows shut tight in the cold weather. but if we don't ventilate the house well in winter, the indoor air pollution can reach dangerous levels. but if you keep these indoors, they will purify your air!

they're air purification plants. the rural development administration selects these purification plants that are perfect for homes. the first is of indoor carbon dioxide. in winter, we spend more time indoors. and we use heaters for long periods of time. that can raise the carbon dioxide levels in the home. if carbon dioxide levels rise, you can experience nausea and headaches.

we visited a family that's worried about their indoor air quality. how often do you ventilate the house in winter? my house lies in front of a main road. so a lot of dust gets in the house and i can't open the windows often. we try to clean the dust but i'm not sure if we're doing it right. we have 3 kids and so when they play

they create a lot of dust. i'm worried about that. the mother is worried that about poor ventilation. we checked the carbon dioxide levels of the home. 1,000ppm is the safe standard for co2 levels. if you're exposed to levels higher than this for long periods of time, you can feel stuffy and dizzy. the co2 levels for the living room... 1,638ppm.

the study that is packed with children's books... 1,697ppm. and in the case of the dressing room... 1,902ppm. it was double the safe standard levels. indoor co2 levels are very high in the winter. what air purification plant would be perfect for this situation? the no. 1 plant recommended by the rda

is the rabbit foot fern. they're easy to grow in all four seasons. rabbit foot fern is used for ornamental purposes. we'd better grow that. how useful would it be in purifying the air? we'll check through an experiment. we install a co2 measuring device in an acrylic box. the safety man blows into the box to increase the co2 levels.

the current measure is 1,783ppm. after an hour passes... what is the co2 level inside the box? 1,777ppm. after another 3 hours have passed... it's still 1,777ppm. there's no difference from the start of the experiment. this time we'll add the rabbit foot ferns that are recommended by the rda.

the current co2 measure is 1,768ppm. we'll observe the change for the next 4 hours. after an hour... 1,549ppm. after 2 hours... 1,338ppm. after 3 hours... 1,060ppm. it's getting closer to the safe standard of 1,000ppm.

another hour passes by. the experiment has been conducted for 4 hours. how much has the co2 in the box decreased by? 661ppm. in just 4 hours, the co2 levels decreased by 63%. rabbit foot fern is the best plant to purify the air inside our homes in winter. peppermint and geranium also help to reduce co2 levels indoors.

the next plant to purify air in our homes. plants to reduce carbon monoxide in the kitchen. a specific plant for the kitchen? the kitchen is the part of the house that produces the most air pollution. when you cook on a gas stove, various noxious chemicals are created. out of those carbon monoxide is created the most. according to one study,

using the gas stove for an hour in a 99mâ² apartment creates the same amount of carbon monoxide as the exhausts of two cars. if you breathe in too much carbon monoxide, you could experience headaches, vomiting and suffocation, all from a lack of oxygen. which air purification plant would be perfect for the kitchen? is devil's ivy.

devil's ivy can grow indoors without any special care. we'll verify its effectiveness through an experiment. we prepared two acrylic boxes measuring 70cm in length, height and depth. then we'll cook fish with a portable stove in each box. the carbon monoxide starts to accumulate inside the acrylic boxes. we'll turn the stoves off now

and measure the carbon monoxide levels. the first box measured 115ppm. the box with the devil's ivy measures 622ppm. we began the experiment with this difference in the measurements. after 1 hour, the first box is at 109ppm. it's about 5% less than at the start. the second box with the devil's ivy is at 534ppm. that's a 15% reduction.

another 3 hours pass by. 4 hours into the experiment... what are the carbon monoxide levels in each box? the first box measures at 102ppm. that's a 12% reduction from the start. the second box with the devil's ivy measures at 165ppm. that's a 74% purification. after observing the box with the devil's ivy for 4 hours

we can see that the foggy smoke is clearing up. can you see the difference from the start to the end of the experiment? the best air purification plant for the kitchen anthurium and japanese cheesewood are also good plants. the next best plant to purify air in the home. this is for sick building syndrome. we visited the home of someone

who is actually worried about sick building syndrome. what have you experienced after moving in here? maybe it's because we moved in winter and i couldn't ventilate the house properly. she'd scratch her arms at night. she'd get scars and discoloring. i'm worried that it might be atopic dermatitis. i can't sleep and i keep scratching. right, mom? children with lower levels of immunity

can develop atopic dermatitis, chronic rhinitis or asthma from sick building syndrome. newly built homes or renovated homes can produce various harmful substances. and the most common of those is formaldehyde. building materials such as plywood and tiles or paint emit the most formaldehyde. 0.08ppm is the safe standard for formaldehyde. we measured the levels in every corner of her home.

the average measure was 0.19ppm. that was two times the safe amount. what purification plant would be good to have in a new home with harmful substances like this one? that would be the broadleaf lady palm. they're normally used as ornamental plants in the office or the home. how effective would it be in eliminating formaldehyde, a cause of sick building syndrome?

first we stored formaldehyde gas in a tedlar bag and added it to an experiment box with the lady palm. the formaldehyde concentration is at 1.56ppm. after an hour that figure reduced to 1.27ppm. how much formaldehyde would be eliminated after another 3 hours? the result is 0.31ppm. in just 4 hours, it reduced to one-fifth of the original count.

the broadleaf lady palm is the best plant for eliminating sick building syndrome. nandina and lavender are also known to be good. what is the last type of dangerous substance that needs to be purified from the home? it's the category 1 carcinogen, fine dust. once it's breathed in, fine dust is difficult to remove from the body. it can travel inside your blood vessels to damage your health.

the most important thing to note is that fine dust is 1,000 times more dangerous indoors. the air purification plant that will protect us from fine dust. recommended by the rda... it's ardisia pusilla. we prepared two boxes for this experiment as well. the first box is empty. the second box contains ardisia pusilla.

then add we yellow fine dust into the boxes. the concentration of fine dust in each box is 947 micrograms... and 1,761.5 micrograms. after 4 hours, how much fine dust is left in each box? the empty box has 771.5 micrograms of fine dust. that's 19% less than the start. the box with ardisia pusilla has 827.8 micrograms.

that's 54% less than at the start. the best plant to purify the air from fine dust is ardisia pusilla. bengal rubber trees are also effective in removing fine dust. various dangerous substances in the air can be eliminated by plants. but how is this possible? the answer is in the leaves.

when we check through a microscope, we can observe fine dust on the back of the leaf. that is evidence that the plant has absorbed the fine dust from the air. we collected a leaf from the experiment and checked under a microscope. you can spot the fine dust stuck around the openings. if the fine dust gathers, photosynthesis is reduced and

the plants stop growing. so you should wipe the leaves to clean the fine dust. let's review the air purifying plants recommended by the rda. to reduce carbon dioxide in winter when it's difficult to ventilate indoors... rabbit foot fern. to reduce carbon monoxide from the kitchen... devil's ivy.

to reduce formaldehyde that causes sick building syndrome... broadleaf lady palm. to reduce fine dust indoors... ardisia pusilla. remember these best air purification plants that will keep the air fresh inside of our homes. this is safety first news. this is for people working in industrial areas.

in order to maintain a safe environment in 2016, we need to get rid of dangers early. wear the right protective gear and make sure you follow safety precautions when you do safety checks before operations. the new start to 2016 is important. make sure you maintain safety regulations! make sure? i'll make sure for you!

this has been safety first news. thank you. ("dark circle" by cocosori)
