'Soundproof tunnel fire' to find out by material... How to prevent a major catastrophe?

<Anchor>

Reporter Kim Ji-wook, who covered this story, is with me.

[Reporter Kim Ji-wook: This is the material called PMMA that was forming the soundproof tunnel at the fire site yesterday (29th).

You can think of it like the acrylic we commonly know.

The reinforced film that is attached to mobile phones is also made of this material.

Basically, since it is a type of plastic, it is very vulnerable to heat.

Also, when heat is applied, acrylic melts and catches fire. At this time, falling objects fall and if they are transferred to combustible objects such as cars like yesterday, the fire grows out of control.]

[Reporter Kim Ji-wook: First of all, a much more detailed and detailed revision is needed than the current regulations.

The current law stipulates that, if possible, materials with excellent sound insulation, durability, and fire resistance should be used, but experts say that materials should be classified according to length and traffic volume.

] I think it is important to avoid using plastic panels.]

[Reporter Kim Ji-wook: Another factor that increased the damage this time was that there was no escape route in the tunnel, and this also needs to be supplemented.

However, if a fire accident like this occurs in the tunnel, you must first bend down as much as possible and turn your body in the opposite direction to the wind to escape.

It is also important to keep supplying oxygen by soaking a mask or towel with water.]
