Replace soundproof tunnels exposed to fire… Introduce mandatory fire fighting facilities


The government is starting to replace materials for soundproof tunnels across the country.

In order to prevent accidents such as the 2nd Gyeongin Expressway Soundproof Tunnel fire, materials that do not burn easily are introduced.

A plan to make fire extinguishers mandatory in soundproof tunnels is also being promoted.

This is the report of reporter Paeng Jae-yong.


The fire accident in the soundproof tunnel on the 2nd Gyeongin Expressway at the end of last year resulted in 49 casualties due to increased damage to fire-prone materials.

Polymethyl methacrylate and PMMA materials, which catch fire easily, were the cause of the spread of the fire, and 58 soundproof tunnels and 1,700 soundproof walls use such materials throughout the country.

The government, which has begun to prepare measures against fire in soundproof tunnels, has decided to completely replace the materials for these facilities with non-combustible materials that do not burn easily.

Among the soundproof tunnels, the aim is to complete the facilities managed by the state by the end of this year, and replace those managed by local governments by February next year.

“The government will fundamentally prevent the possibility of fire by overhauling the soundproofing installation standards and the control system.”

As it takes time to replace the soundproof tunnel material, the government is also taking temporary measures such as removing part of the top or side of the fire-dangerous tunnel and securing an evacuation space.

In the case of soundproof tunnels to be installed in the future, the use of PMMA materials will be prohibited, and the installation of emergency exit doors and escape routes will be mandatory.

In addition, when establishing urban planning, it is a policy to prevent the installation of soundproof tunnels by preventing noise-sensitive residential facilities from entering the vicinity of roads.

“We are preparing to review the necessary guidelines for the development of housing sites so that business facilities or parks that are insensitive to noise can be placed in parts close to the road.”

The Ministry of Land, Infrastructure and Transport plans to cooperate with the police to prevent accidents by installing speed limits and speed cameras in soundproof tunnels.
