I'm sure there are a lot of people who have been relieved by the record-breaking heavy snow in November. But it's still too early to feel safe. There is still snow news in some areas today, and the morning temperature drops sharply, raising concerns about icy roads. Let's take a look at what to be careful of with Lee Young-joo, a professor of fire and disaster prevention at Kyungil University. Is the professor here?

[Lee Young-joo]
Hello.

[Anchor]
The temperature dropped sharply this morning. Is there a possibility that the previously melted or melted snow will freeze as the temperature drops to below zero?

[Lee Young-joo]
That's right. It is said that the temperature is below zero in Seoul and the metropolitan area and the cold weather continues until this morning. As a result, the snow accumulated yesterday, the day before, and some parts melted by the snow removal can be frozen and dangerous overnight. On the other hand, as the sun rises and warms again during the day, the melted ice and snow melt, and these parts fall from the building or fall, which can be dangerous for safety while walking. You can see it like this. On the other hand, water and water dissolved on the road surface overnight are frozen again, and the road surface is very slippery, such as black ice and icy roads. So you have to be careful about these things.

[Anchor]
I'm more worried because the black ice and road freezing phenomenon you mentioned are not visible with the naked eye. It's also time to go to work ahead of the full-fledged rush hour, so what should I pay attention to?

[Lee Young-joo]
When it's this dark until it's completely bright, it's generally a dangerous situation because the view is not well secured when driving. Please turn on your headlights as much as possible. Also, it is necessary to check the road frequently when you turn on the headlights. It's hard to see the black ice with your eyes.Ma is in these situations where there is more reflection of the twinkling light when the light is shining, so if the road surface is reflected a lot by the headlights, you can think of it as black ice here. On the other hand, there is a high possibility that the road is frozen in places such as shaded areas and side roads, so you should drive carefully. Also, when driving on a slippery road, you need to decelerate and secure enough safety distance. Also, in the case of slippery roads, you cannot avoid collisions with subsequent vehicles if you do sudden stops or sudden speeds, so you should refrain from driving as much as possible. If you need to slow down, it would be better to divide the brakes several times in advance and do things like driving without difficulty in the process of applying the brakes. Also, if it's really difficult, I recommend you to use an engine brake that slows down the gear.

[Anchor]
I think you need to pay a little more attention to driving. Collapse accidents caused by this practice have also occurred everywhere. The snow has stopped now, but if there's still snow, it's better to remove it, right?

[Lee Young-joo]
Of course, snow removal is necessary because the snow continues to be forecasted today, so it may be dangerous to build up more. However, when snow removal is done, it is necessary to remove snow considering all the safety and the risk of collapse of those who do snow removal. I think it would be better to remove snow in a safe environment as much as possible rather than to forcefully remove it. In the case of general buildings, the structural risk is relatively small. Greenhouses, temporary structures, and temporary structures are likely to collapse when snow accumulates, so you have to remove snow. In this case, if you go up to the roof and remove the accumulated snow, the load of snow, the load of workers, and these things are dangerous, so it's better to minimize snow removal by going up to the roof. I think so.

[Anchor]
You also advised me to ensure my safety. Ice on the road is also a problem, but pedestrians should also be careful of thin ice, right, professor?

[Lee Young-joo]
That's right. Many people talk a lot about the road because of the road that cars drive on, and because of the series of crashes, but in reality, the safety of pedestrians is also very important. In India and India, where people travel, safety while walking is also very important because snow removal is not done or ice freezes in places where many people travel. If you walk with your hands in your pockets because it's cold, it's hard to cope with slipping or falling, so it's safer to wear gloves, take your hands out, and walk. Also, of course, if you walk while looking at things like cell phones, it's difficult to check the ice or road conditions on the road, so of course, you shouldn't do cell phones while walking. Also, it would be safer to wear sneakers and hiking boots that have a wide floor and prevent slipping than slippery shoes and slippers. When you walk, reduce your stride a little more than usual so that you can cope with slipping a little more. So it may be a little safer to walk in small steps than usual. On the other hand, even if the ice does not freeze directly, there is water on the floor or snow has fallen while the leaves have fallen recently, so you should walk carefully to these areas because they can be slippery when wet.

[Anchor]
When you walk around, you should walk in small steps and often. It would be a relief if the snow stopped, but there are places where there is news of snow in the afternoon. What would you be concerned about if it melted and then froze, and then it snowed again on that icy road?

[Lee Young-joo]
Basically, as you said, in the case of cold, for example, yesterday, it snowed overnight, and there were parts that melted naturally as the temperature of the video reached during the day, and there were parts that were easy to snow removal. However, if it freezes in cold weather like this, there is a possibility that road conditions will get worse because even if you spray snow removal or snow removal, it will be difficult to remove enough snow. That's why we need modern snow removal.Things like slippery conditions when it snows a lot, keeping the things we're talking about now so that there are no additional risks or injuries. On the other hand, the roof was frozen with snow and ice. As they melt repeatedly, they are in the form of hard ice, so these things are piled up in the form of ice in the building, and as the weather gets warmer, these ice falls and falls on pedestrians and injures them. So in this situation, it is necessary to remove icicles or ice parts on the roof. If it is difficult for individuals to do these things, it is also necessary to actively remove these parts with the help of the fire department.

It will be important to take a good look at the surrounding geographic structures. Also, it is the mountainous area that is particularly concerned about snow damage. It is said that up to 15cm of snow is falling in the mountains of Jeju and up to 7cm in the eastern part of Jeollabuk-do. Of course, but I have to be careful about climbing the mountain, right, professor?

[Lee Young-joo]
Yes, not only do you have to be careful about climbing the mountain, but it's best not to climb the mountain if it's snowing so much and you're expected to come. Nevertheless, some people who fall in love with snowscape or snow mountains go there, and in this case, you need to prepare a little more. Basically, there is a lot of snow on the hiking trail that you usually go to, and snow removal is not done, so you should pay attention to safety while hiking and walking. On the other hand, because it snows a lot, there are situations where branches and trees themselves fall, so you should not just pay attention to safety on the walkway, but prepare for the dangers of nearby trees and evangelism. Also, there are situations where it snows a lot in the middle of climbing the mountain, so you need to be clear about your location and how to report it. In case of isolation, there is a possibility that you need to bring clothes that can keep you warm enough, blankets, and emergency food just in case.

[Anchor]
You talked about the need to keep warm in the case of isolation in the mountains, and isn't it possible that rural areas or mountain villages themselves may be isolated? I think we need to prepare for this at the village level.

[Lee Young-joo]
That's right. There can be situations where road conditions are isolated because of snow. Various isolation can occur, and in this case, you have to live in it for a certain period of time, so you need to prepare emergency food and drinking water you mentioned for this time. On the other hand, if it snows so much and becomes isolated, there is a possibility of power outages or water cuts. You need to prepare for things like securing emergency power in preparation for these things. In any case, if isolation occurs, you need to report it quickly so that if it is difficult to get out of isolation, you can come to the rescue from the other side. In addition, there are various risks that can be caused by snow accumulating inside, so it is necessary to actively manage facilities and maintain vehicles on a regular basis.

[Anchor]
I think it would be good to remember if you are in areas with high risk concerns. Winter can be said to start from now on, but there will be frequent humid and local heavy snow this winter. What should I prepare to reduce the damage?

[Lee Young-joo]
A lot of weather forecasts and a lot of snow fell this week. Rather, I think we can prepare for this winter because of the snow experience. So basically, the snow that falls frequently. We've experienced a lot of these things.Since PC is very inconvenient in traffic and there are various risks, snow removal work needs to be preemptively carried out at that time. So, each local government needs to have equipment and supplies for preemptive snow removal, and response systems to weather disasters once again.
On the other hand, even if snow removal is carried out, there are areas where it is difficult to do everything in such detail as alleys. In this case, it is important to check whether the snow removal system and the equipment and management of the snow removal box are going properly and to ask local governments for these parts if necessary. On the other hand, it is important to prepare for various difficulties or risks in the event of snow removal.

[Anchor]
I see. Preparation for snow removal continues to be important. So far, we've talked with Lee Young-joo, a professor of fire and disaster prevention at Kyungil University. Thank you for talking today.
