A joint identification was held on the fire at the parking tower of an officetel in Busan that occurred yesterday (9th).
It was investigated that the adhesive in the aluminum panel, not the previously known flammable material Dryvit, raised the flames.

red-hot pillar of fire engulfed the 23-story parking tower.
The flaming exterior material fell to the floor and the flames spread to nearby shopping malls.
It took over 8 hours to completely put out the fire.
As a result of on-site identification, the first fire started in the alley behind it.
After that, they quickly rode up to the top of the building in a V-shape.
Fortunately, it was confirmed that the vehicle in the parking tower had no major damage.
[Park Hee-gon/Fire Investigation Manager, Busan Fire and Disaster Headquarters: Looking at the fire pattern, it is estimated that the fire broke out on the first floor.]
A joint investigation revealed that the exterior material that caught fire was an aluminum composite panel, not Dryvit as originally known. lost
It is a sandwich structure with 4 thin aluminum sheets and glass fibers, and it is estimated that the adhesive used to attach the aluminum served as a fire starter.
[Choi Jae-wook/Professor of Fire Protection Engineering, Pukyong National University: Adhesive is needed to attach an aluminum panel, which is a non-combustible material.
Since the adhesive is made of a material that can burn easily, it can be said that it is a fire vulnerability.]
In the past, high-rise apartment fires in Haeundae and Ulsan also fueled the flames with the adhesive in the aluminum composite panel.
Currently, it has been confirmed that 27 apartments with 30 floors or more in Busan are also aluminum composite panels.
Since there is no separate regulation for flammable adhesives, it seems necessary to prepare related regulations even now.
