Expert: ”Air mattress installation is problematic, but it may also be defective”... Hotel fire in Korea

On the 22nd of this month, a hotel fire in Bucheon, Gyeonggi-do, killed seven people, two of whom jumped onto air mattresses.
Professor Yeom Geon-woong said, "There was clearly a problem with the air mattress," raising suspicions of inappropriate installation locations and defective products.
In an interview with CBS Radio on the 26th, Professor Yom said, "The installation site was a ramp, but the air mat
"Even if air mattresses are installed on a flat surface, the chances of survival are greatly reduced if you jump from a high-rise building. However, according to the building register,
The height of the building is 29.4 meters, and the fire department's performance certification and product inspection technical standards state that the air safety mat can only be used when the building height is 15 meters or less.
The moderator asked, "Is it stipulated that air mattresses should not be used in buildings over 15 meters high?"
"It's not that we should not jump, but that we should only use it at heights of 15 meters or less because safety is not guaranteed," he said, adding, "The best chance of survival if you jump onto an air mat is
Professor Yom added that the highest level was the fourth or fifth floor. With regard to the fact that the air mattress flipped over immediately after one of the people in need of rescue jumped off at the time of the fire, he said, "According to the manual, it says that no one should be able to use the air mattress.
"As a result, an extremely unusual situation occurred in which the air mattress was flipped over," Professor Yeom said.
"The air mattress has a lifespan of seven years, but the product is guaranteed to last for seven years. However, we discussed reusing it and used it for more than twice that period. If that happens, the elasticity of the rubber will naturally decrease.
"Also, when the air was pumped in, it could have been pumped in unevenly or the air could have escaped. Therefore, it is believed that there was a good chance that the air mattress was defective."
In this case, the first-arrival team from the Bucheon Fire Station arrived at the scene at 7:43 pm, four minutes after the call, and set up air mattresses on the first floor outside the hotel at 7:48 pm.
However, one of the two people in need of rescue in a guest room on the seventh floor fell to the edge of the air mattress, causing it to flip over due to the force of the fall. He jumped off two to three seconds later.
One of the victims fell to the ground, and both went into cardiac arrest and were taken to hospital but later died.
