Is it possible to ignore the new national elevator safety escape door?

Safety doors must be installed, which is the national standard.

There is no such thing as not having it. To increase the structure and increase the cost, it is also necessary to install safety doors.

According to regulations. 1) When the spacing of the adjacent two layers of door sill is greater than 11m, the hoistway safety door with a height not less than or width not less than that is not less than that shall be set up during the period (except when using the car safety door);

2) Do not open to the hoistway;

3) The door should be equipped with a lock opened with a key, when the door is opened, it can be closed and locked without a key, and after the door is locked, the door can be opened from the hoistway without a key;

4) An electrical safety device should be set up to verify the closed state of the door.

1.Retractable speed gate (wing gate).

The telescopic speed gate is a fast, smooth can be single-item or two-way control access, power-off automatic wings, with infrared detection of the main anti-pinch function, at the same time, after continuous multi-person passing, automatic closing, reduce mechanical consumption, increase life.

2.Swing gate. The swinging speed gate is a type of speed gate with a high level of safety protection.

Pedestrian access control equipment. It provides high-security control of traffic in both directions, effectively preventing illegal entry, tailgating entry, etc.

3.Optical doors.

According to regulations. 1) When the spacing of the adjacent two layers of door sill is greater than 11m, the hoistway safety door with a height not less than or width not less than that is not less than that shall be set up during the period (except when using the car safety door);

2) Do not open to the hoistway;

3) The door should be equipped with a lock opened with a key, when the door is opened, it can be closed and locked without a key, and after the door is locked, the door can be opened from the hoistway without a key;

4) An electrical safety device should be set up to verify the closed state of the door.

Hello, I am happy to serve you and give you the following answer: the elevator entrance and exit can not be installed in the escape area, because this will affect the efficiency of the escape. Workaround:

1.Set the elevator entrance and exit outside the escape area to ensure the safety of the escape area. 2.

Set up safety measures at the elevator entrances and exits to prevent the elevator entrances and exits from being blocked in the event of a fire. 3.Set up emergency buttons at elevator entrances and exits to facilitate timely emergency evacuation in the event of a fire.

4.Set up fire extinguishers at the entrances and exits of the elevator to extinguish the fire in time when the fire is slippery. 5.

Set up emergency lights at the entrances and exits of the elevator to provide timely lighting in case of fire. Personal tip: When setting up the elevator entrance, special care should be taken not to set it up in the escape area to ensure the safety of the escape.

At the same time, safety measures should be set up at the elevator entrances and exits, bridges should carry disadvantages to prevent the elevator entrances and exits from being blocked in the event of a fire, and emergency buttons, fire extinguishers and emergency lights should be set up to evacuate and extinguish the fire in time when a fire occurs.

Summary. The elevator safety door allows people to enter and exit for a long time. However, it should be noted that personnel need to pay attention to their own safety when entering and exiting to avoid being caught by the door or causing damage to the door.

At the same time, it is also necessary to comply with the elevator use regulations, such as not overloading, not jumping in the elevator, etc., to ensure that everyone can use the elevator safely.

Can you add, I don't quite understand it.

The elevator safety door is not the main passage for personnel to enter and exit the elevator, but is a facility used to prevent personnel from accidentally entering the elevator shaft and causing safety accidents. Therefore, in the case of general pin burial, the elevator safety door should not be used as the main entrance and exit of personnel, and the entry and exit of personnel may affect the normal service life of the elevator for a long time, so it is recommended to avoid it as much as possible.

The elevator does not have anti-high temperature performance, and the elevator compartment is easy to lose control or even deform and get stuck. In a fire, the chimney effect is easy to occur when the elevator is running, which threatens the safety of passengers. The fire may cause a power outage, and the elevator will stop in the middle of the two floors, which is not conducive to the escape of the people in the elevator.

When people are trapped in an elevator, the airtight elevator will make it difficult for firefighters to rescue them. <

3. The fire may lead to a power outage, and the elevator will stop between the two floors, which is not conducive to the escape of the personnel in the elevator mountain.

4. When people are trapped in the elevator, the closed elevator will cause difficulties to the rescue of firefighters.

Are you referring to the access control with a card reader?

The situation where emergency evacuation is required is that the building has a serious disaster, such as fire, **, collapse, etc.

In the event of a serious disaster, the first thing that happens is that the building's power supply system is interrupted (due to the disaster) or cut off (for safety) - the power is cut off, and the people who flee into the elevator for refuge are equivalent to entering a tin box hanging on a cliff, and there is no way to go to heaven and no door to enter the ground.

When you evacuate in an emergency, you must remember to rely on your own physical strength to escape, and the only person you can rely on in a disaster is yourself.

In accidents, fires and other accidents, the elevator is easy to get out of control, causing tragedy.

1.When escaping from a fire, there are many things worth noting: First, don't get into the elevator when you escape.

In the event of a fire, the elevator will be unable to rise and fall due to power failure or thermal deformation, so that the personnel are trapped in it, and the elevator shaft is like a chimney, running through each floor, and toxic smoke is easy to collect into it, which will directly threaten the lives of the trapped personnel.

2.The elevator goes straight to all floors of the building, and the smoke on the fire scene pours into the elevator passage very easily causing the "chimney effect", and people will be choked by the smoke and poison gas in the elevator at any time and suffocate to death.

3.After a fire occurs, it is often easy to cut off power and cause the elevator to be "stuck", which brings difficulty to the rescue work and affects the timely rescue.

You can't see this warning next to any elevator: "If you are in case of fire, you must not use the elevator, please take the stairs." "No matter which floor of the resident's home fire, the property company's first reaction is to force the elevator to the first floor and cut off the elevator power.

In the eyes of fire experts, this approach is too arbitrary. For example, if a high-rise building has 30 floors, and a kitchen on the 21st floor catches fire, it does not affect the residents of the other floors to evacuate by elevator. If the elevator is out of service at this time, the firefighters will have to climb the stairs to reach the 21st floor, which will not only waste time but also delay the rescue.

If the elevator can be used, residents on other floors will be able to evacuate faster, and firefighters can also take the elevator directly to the 20th floor, and then take another staircase to the fire scene. "In this way, the rescue time will be saved a lot, and the physical exertion of the firefighters will be reduced. ”

Experts also told reporters that according to scientific statistics, when there are 120 people on each floor, on the 15-story building, it takes 19 minutes for people to evacuate from the stairs to the ground, and 39 minutes for the 30th floor, while the general fire only takes 20 to 30 minutes from ** to fierce burning. Evacuation staircase is the main evacuation method advocated at present, but the evacuation time is too long, which is not conducive to the evacuation and escape of vulnerable groups. "If an elderly lady or a pregnant woman who lives on the 50th floor is caught in a fire, she has to go down from that high ground to the next floor, according to the existing regulations, and there is no guarantee that other accidents will happen.

At the same time, the existing ladders, helicopters, and personal descent devices are limited in the number of people rescued, which cannot meet the needs of a large number of people to evacuate and escape in a short time.

After a fire, people often worry that the high temperature will deform the elevator car. However, if the average resident's home is on fire, it is not a threat to the elevator door that can withstand high temperatures of more than 800 meters. At the same time, the smoke detector will collect the temperature outside the elevator car in time, once the temperature exceeds the warning line, the elevator will automatically stop the stop on the floor, and other floors that are not on fire can still use the elevator for evacuation.

In other words, if there is a fire on the 28th floor, only the elevator on the 28th floor will stop. Residents on the 27th and 29th floors will still be able to use the elevator to escape safely, and will not be affected at all. ”

In fact, there are many examples of successful use of elevator fire escape around the world. During the 9/11 terrorist attack in New York, 31 staff members on the 91st floor of the South Building were evacuated by elevator in just 72 seconds. On October 28, 1996, a fire broke out in a 20-story high-rise apartment in Hiroshima, Japan, and later investigation found that more than half of the evacuees in the fire used elevators to escape the fire scene.

In 1974, a 25-story window air conditioner caught fire on the 12th floor of the Gioma Building in São Paulo, Brazil, and at the beginning of the fire, 4 elevators successfully evacuated a total of 300 people, accounting for 71% of the 422 survivors.
