Escape Stairs – Structured rescue network in buildings
In high rise buildings, escape stairs are a must-have structure in design, construction and operation. Unfortunately, most people and even managers do not always attach importance to this “life saving” structure.

Exit exit stairs are always closed by hand, isolate the corridor and walkways (Photo BQT).

On television and if someone has the opportunity to go abroad will easily see the stairs, exposed, outside the building. These are escape stairs outside the building used in emergencies, especially when a fire occurs.

Fire-escape is an indispensable element in the design and construction of high-rise buildings, to use the escape for emergencies and hazards such as fire, fire, In accordance with the Construction Standards of Vietnam and the National Technical Regulations on the Safety of Houses and Buildings (attached to Decision No. 439 / BXD-CSXD of September 25, 1997 of the Minister of Construction and the Circular No. 07/2010 / TT-BXD dated 28/07/2010 of the Ministry of Construction), tall buildings are subject to management of fire prevention and control, tall buildings must strictly comply with standards, regulations on fire prevention and fighting; Must be approved by the competent state management agency in charge of fire prevention and control, pre-acceptance test, construction work, etc., of the fire prevention and fighting items of the works before the works go into construction and ensure the safety of fire prevention. fire, escape, escape … for people in the works when put into use, operation.

Back in the 1960s, 70s of the last century, in the North, collective buildings sprouted in Kim Lien, Trung Tu, Thanh Xuan (Hanoi) but people do not see this structure appear. Stairs and escape stairs are all in the same function and located in the middle of the building. In the south, housing built by the Saigon government, this structure is equipped but due to the urbanization speed too fast, these escalators gradually turn into ordinary stairs.

When skyscrapers begin to rise, these structures are introduced into the building and many investors are required to incorporate them into the design as part of their safety criteria. However, not everyone in the apartment understands that this is the structure that saves itself when a fire or emergency occurs. Many employees of the building management said that it was hard to persuade residents in the building to adhere to the principle of fire safety, especially respecting the rules of use. emergency staircase.

According to a specialist working in the field of building management, the death toll in the Carina apartment fire on March 25 will be limited to the lowest level if residents in the building are equipped with knowledge. The minimum fire, the things that all people in the apartment to comply.

What is the minimum knowledge about fire protection in the apartment? Let’s take a closer look at the basic knowledge of fire prevention in apartment buildings, especially the escalators in the building, through the following interview with Mr. Hoang Tuan Ngoc – a specialist long time in the field of apartment management.

Q: When there are fire alarms why not use elevator?

Answer: When there is fire alarm, absolutely and absolutely not used elevator. We stress that elevator lifts should not be used in the event of fire. Because the elevator is the killer trap when a fire occurs. Even a very small fire, completely stuck, but people trapped in the elevator is still dead as usual. When a fire occurs, the electrical system will cut off completely to ensure safety. People trapped in the elevator will die of smoke, because of lack of oxygen, because of cable break, elevator chamber fell free, the rescue, firefighters do not know the elevator at any floor that rescue …. For those reasons, absolutely do not use the elevator in fire and other emergencies. Carina, of the 13 dead, has a family of five killed in the use of elevators and death due to asphyxiation.

Question: Why do not arbitrarily inserted stones to the door of the escape stairs so that the door is always open, convenient to travel?

Answer: No and absolutely not arbitrarily inserted stones on the door of the escalator to open the door, convenient to travel. I would like to explain relatively simple and short as follows:

There are two types of exit stairs: outdoor and indoor. Outdoor type is simple, easy to use and usually applies to buildings under 10 floors. However, the ladder of escape in the home, few understand its principles. Exit stairs in the house designed with the important purpose is to create space for residents when the fire escape smoke. This is the space of smoke, toxic gas. Thus, escape stairs in the building are always insulated almost completely with space
