This accident is similar in many ways to the fire in a frozen warehouse in Icheon, Gyeonggi Province in 2008. At that time, the fire started with an urethane explosion, and 40 people died. Since then, there have been talks about the need for safety measures, but after 12 years, nothing has changed significantly.

fire in the frozen warehouse in Icheon in 2008 that killed 40 people.

At the time the Gyeonggi Firefighting Headquarters published, the accident white paper states that volatile vapors were generated during the operation of the urethane, which is an insulating material, and an explosion occurred while a spark sparked.

The cause of the fire in the warehouse is also estimated to be similar.

[Seung-Hyeon Seo / Governor of Icheon Fire Department, Gyeonggi Province: As the steam explodes during urethane work, the combustion is rapidly expanded (estimated.)]

Logistics warehouses are usually made of sandwich panels and then padded with urethane foam made by mixing various chemicals in the field. Does the work.

In the process, a strong vapor is generated, and even if a small flame sparks, the fire spreads in an instant.

When urethane foam burns on fire, it causes fatal poisonous gas such as hydrogen cyanide, which leads to suffocation.

In both accidents, the fire started in the basement, causing greater damage.

[Lee Young-ju / Professor, Department of Fire and Disaster Prevention, Seoul National University: In the case of underground spaces, ventilation is poor, so there are a lot of cases where the combustion is suddenly caused by fire.]

Safety anxiety has been repeated this time.

[Professor of the Department of Fire and Disaster Prevention, Konghaseong / Woosuk University: Investing in safety costs a lot in terms of economy For example, urethane foam can also be made of non-flammable materials, because it can cost more than 1.5 times… ]

Similar cause, similar space.

Although many concerns were raised about safety accidents at the construction site, Panbak could not prevent the disaster.
