On April 20th, Changsha Fire Rescue Detachment stopped using all the business areas of Meilande Club Children's Paradise (Changsha Runxin Yue Le Culture Development Co., Ltd.) located at Hisense Plaza 1 12, Shop 209 and Shop 2 18. The Mokado Fitness Center (formerly Boxing Age Gym) on the 8th floor of Golden Bund Apartment was temporarily sealed up. ?

Take out a special floor of the super high-rise building as the refuge floor. The refuge floor has special fire-fighting smoke exhaust fans, power distribution rooms, broadcast rooms and other equipment for people to wait for rescue.

In order to prevent people from evacuating, many people don't know the existence of the refuge floor. When they evacuated to the refuge floor along the stairs, they did not go to the refuge floor and continued to run down.

When designing, the smoke-proof stairs passing through the refuge floor should be separated, dislocated on the same floor or disconnected from the upper and lower floors, but people must pass through the refuge floor. So that people can escape safely when they are in danger.

The starting point of setting up the refuge floor is to provide a place for those who are physically exhausted to temporarily escape from the fire, as a place for temporary rest and waiting for rescue. The refuge floor is actually not absolutely safe. After 9. 1 1 in the United States, there has been a discussion in China about whether the dislocation of evacuation stairs on the same floor of the refuge floor can be cancelled. 9. 1 1 in the United States is an extreme case, but no one who stayed on the refuge floor at that time gained a higher chance of survival because the whole building collapsed. So after 9. 1 1, everyone began to discuss whether it was really so safe to stay in the refuge floor.

After the fire broke out in the lower level of the refuge floor, it is difficult to predict whether the people taking refuge in the refuge floor are safe or not, because it involves management, use and other aspects, which are often the main causes of major accidents.

For this problem, we can also consider it from the perspective of evacuating stairwells. From the normative point of view, the evacuation stairwell is a safe exit for people, and it is generally considered that people are safe when they enter. However, in the actual operation of buildings, normally closed fire doors often open for a long time, door closers fail, and smoke prevention systems fail. Judging from these phenomena, it is actually difficult to absolutely say that the stairwell will be 100% safe in a real fire. The refuge floor is the same.
