The refuge floor is a protected floor in a building, which serves as a temporary shelter for residents in the building to gather and rest temporarily in case of fire. Generally speaking, all buildings with a height of more than 25 floors above the lowest ground floor must be provided with refuge floors (except residential buildings or multi-purpose buildings with a height of no more than 40 floors), and the refuge floors must be located in the floors with a maximum distance of 20 floors (in the case of industrial buildings) or 25 floors (in the case of non-industrial buildings) from any other refuge floors. If the height of a residential building or multi-purpose building is higher than the lowest ground floor by more than 25 stories, but not more than 40 stories, the roof of the building concerned can be regarded as a fire shelter.
The influence of the refuge floor of the building on the residents downstairs is that once the high-rise building is surrounded by fire and the fire escape cannot get up and down, it is necessary to wait for rescue on the refuge floor. Under normal circumstances, people hiding in the refuge floor are likely to survive. The advantage of buying a house on the first floor of the refuge floor is that there is no one upstairs, so you don't have to worry about the bathroom leaking to your home. The following other equipment is often placed on some equipment floors, which may cause some noise.
