Tips on safety for people trapped in elevators

1. Elevator safety knowledge: How to rescue yourself when trapped in an elevator. Details

Those who are trapped in an elevator need to master the following self-rescue methods to ensure safety and obtain rescue.

1. Stay calm, comfort the people trapped together, and explain to everyone that there is no danger and the elevator will not fall down the elevator chute. The elevator trough is equipped with an anti-fall safety device, which will firmly clamp the rails on both sides of the elevator, and the safety device will not fail.

2. Use the alarm bell, walkie-talkie, or mobile phone to call for help. If there is no alarm bell or walkie-talkie, and the mobile phone is out of order

, you can knock on the door and shout. If you are afraid of hand pain, you can take off your shoes and knock on it. , requesting someone to be rescued immediately.

3. If you cannot find an elevator technician immediately, ask someone outside to call the firefighters. Firefighters usually winch the elevator up or down to the nearest floor and then open the door. Even if there is a power outage,

firefighters can still use manual tools to winch the elevator up and down.

4. If there are no trained rescuers outside, do not climb out of the elevator by yourself.

5. Never try to force open the inner door of the elevator. Even if you can open it, you may not be able to reach the outer door. Of course, you cannot open the outer door to escape safely. Grease on the outer wall of the elevator may also cause people to slip.

6. If there is an emergency exit on the elevator ceiling, do not climb out. Once the exit panel is opened, the safety switch will stop the elevator. But if the exit panel is accidentally closed, the elevator may start suddenly

causing you to lose your balance. In the dark elevator shaft, you may trip over the elevator cable or step on the oil

He slipped and fell from the top of the elevator.

7. If you are trapped in the elevator of a commercial building late at night or on a weekend afternoon, it is possible that no one will approach the elevator for hours or even

days. In this situation, the safest thing to do is to remain calm and wait

for help. It is best to endure the pain of hunger, thirst, and sweltering heat to save your life, and pay attention to the movement outside. If there is a pedestrian passing by, try to attract his attention.

2. What are some safety tips when taking the elevator?

Safety tips for riding the escalator:

1. For lace-up shoes, make sure the laces are tightly tied. When wearing loose clothes or skirts, be careful to gather them with your hands to prevent them from being caught on the escalator and causing unnecessary injuries.

2. When children go up the escalator, remember to have an adult hold their hands and do not let them touch them. Do not chase, play or climb at the elevator entrance or on the escalator. When the elderly go up the escalator, they must hold on to the handrails. , to help maintain body balance.

3. Keep your head and hands away from the escalator to prevent being hit or pinched by nearby obstacles during the operation of the escalator.

4. When riding an escalator, you should stand upright facing the direction of the escalator and hold your hands on the handrails. Do not lean on the handrails. Stand with your feet together within the yellow line around the pedals to prevent the edges of your trouser legs from being caught in the movement. In the gap of the elevator.

5. It is not scientific to stand on the right side of the escalator and leave one side for traffic. Because walking on the escalator is unsafe. Passengers are advised not to walk on the escalator as much as possible. A maximum of two people can stand on one escalator step. If you see too many people on the escalator, it’s best to take the stairs.

6. Do not stay at the entrance and exit of the escalator, do not let children run back and forth on the escalator, and do not kick the escalator strips with your feet to avoid danger.

7. Do not extend your head or limbs beyond the handrail device to avoid being hit by obstacles, ceilings, or adjacent escalators.

8. Carry handbags with you and do not place them on the step treads or handrails to prevent them from rolling down and injuring people.

3. What are the correct operating methods and steps for trapped people in the elevator?

1. Determine where the elevator stops;

2. Notify the trapped passengers to rescue them Work is in progress, do not open the elevator door without authorization to avoid accidents, and you must remain calm;

3. Make sure all elevator hall doors are closed and cut off the main power supply of the elevator;

4. Reminder For passengers in the elevator, the elevator will go up or down slowly;

5. There must be two or more people to manually turn the elevator, cooperate with each other, and give unified command;

6. Promote the Turn the rocker arm on the brake to open the brake (refer to the diagram in the manual), then turn the winding wheel by hand to raise or lower the elevator as shown by the arrow;

7. Level the machine to the nearest floor (see the wire rope leveling sign), use the elevator's special key to open the hall door, release the trapped passengers, and then notify maintenance personnel for repairs.

4. Safety common sense when using elevators

Elevators are very safe transportation equipment. Potential safety hazards are usually caused by aging parts and inadequate maintenance or scheduled maintenance.

For straight ladders, you should pay attention to the following aspects.

1) For passengers, the first is shearing danger, do not stay at the door;

2) The most common hazard to passengers when the elevator fault electrical protection is activated That is, they are locked in the car. When encountering a power outage, safety switch malfunction, loose door contact, system interference, etc., the elevator will suddenly stop and trap the passengers in the car. At this time, if you want to Contacting the outside world for rescue is much less risky than self-rescue.

3) Be careful when entering the elevator door, especially old elevators or elevators under maintenance. In the former case, stick to the first rule. In the latter case, do not enter the elevator. Of course, You may not be able to enter.

For escalators, it is not advisable to wear relatively long skirts and particularly soft slippers. One hand should hold the armrest firmly. Old bags should not stick out of the armrests.

5. What are the common sense about elevator safety?

First of all, we must look at the quality of the elevator.

In order to meet market demand, elevator manufacturing companies will produce elevators of different grades, with different performance indicators such as load capacity and speed. The prices range from hundreds of thousands to millions of yuan, and comfort, Reliability also varies. For residential elevators, some developers often choose lower-priced general brands and low-grade elevators in order to reduce costs.

In order to seize the residential elevator market, elevator manufacturing companies will also reduce prices by reducing material costs and reducing configurations. Home buyers should try to choose homes with elevators of well-known brands, good performance, and high configurations.

Secondly, it depends on the quantity configuration of elevators ("one elevator for several households"). If the number of elevators in each unit of a residential building is small, the frequency of use will increase, the mechanical and electrical components of the elevator will wear and age faster, the failure rate will increase, and the service life will be reduced.

Relevant national design specifications divide residential elevator configurations into four levels from "economical" to "luxury" and stipulate that for high-rise residential buildings with 12 floors or above, the number of elevators should be no less than 2. When 25 people live on each floor and the number of floors is 24 or more, at least 3 elevators should be installed; when 25 people live on each floor and the number of floors is 35 or more, at least 4 elevators should be installed.

The "National Civil Construction Engineering Design Technical Measures" stipulates that the number of passenger elevators needs to be determined based on factors such as different building types, number of floors, area of ??each floor, number of people, and main technical parameters of the elevator. The number of elevators in residential buildings is configured according to the economic level: 90-100 households/unit; the common level: 60-90 households/unit; the comfort level: 30-60 households/unit; and the luxury level. For residential elevators, owners usually entrust property companies to perform elevator safety management. Responsibilities; if the newly installed elevator has not yet been handed over to the property owner (person) or property management unit, the project construction unit shall serve as the usage management unit and perform its obligations and assume responsibilities.

After the owner entrusts the management responsibility of the elevator to the property management company, not everything will be fine and he can just let go. It is necessary to play the role of owner, pay property management fees including daily elevator maintenance fees on time in accordance with the property service contract, and urge the property company to do a good job in daily management and maintenance of elevators.

Article 13 of the "Special Equipment Safety Law" stipulates: "Special equipment users and their principal persons are responsible for the safety of the special equipment they use." At the same time, Article 38 states that "Special equipment belongs to ***Yes, ***someone can entrust a property service unit or other manager to manage special equipment. The trustee shall perform the obligations of the special equipment user unit stipulated in this law and bear corresponding responsibilities. If ***someone fails to entrust it, the trustee shall. ***Someone or the actual manager performs management obligations and assumes corresponding responsibilities.”

Will elevators that pass the inspection malfunction? Elevator inspection is a verification inspection of the elevator production and use units' compliance with relevant laws and standards and the implementation of the main responsibility for elevator safety. The final conclusion of the inspection report issued by the inspection agency is a judgment on the quality of work such as the implementation of relevant responsibilities by the elevator production and user units.

Just like a person's "physical examination" and annual car inspection, elevator inspection is a verification and diagnostic technical behavior. It mainly discovers safety hazards, puts forward rectification suggestions, and supervises production, use management units and maintenance The unit strengthens management and maintenance to ultimately eliminate hidden dangers. The inspection conclusion is only a judgment based on the safety status of the elevator at that time. It is not a guarantee that the elevator will be safe and qualified within one year, nor is it a promise that the elevator can operate without failure.

Even if an elevator passes the annual inspection, it may still break down during daily operation if it is not used properly, is not managed well, and maintenance is not in place. After a failure occurs, repairs must be made promptly, and parts that must be replaced must be replaced in a timely manner. Especially for elevators with a long service life, frequent use, and high failure rates, they must be overhauled, remodeled, and updated in a timely manner to eliminate safety hazards in a timely manner and make them more efficient. The elevator reaches a better safety condition.

After the elevator is overhauled, renovated, or updated, it must be supervised and inspected by the elevator inspection agency before it can be put into use. Elevator safety knowledge Q: Why do elevators "trap people"? A: The most important and primary concept in elevator design is to ensure safety.

Therefore, elevators are designed with many safety protection devices. When the elevator control system or safety protection device senses a possible danger, it will start immediately to stop the elevator.

Therefore, "stopping the elevator to trap people" is actually a safety protection measure taken by the elevator for the passengers in the car. Q: What should I do if the elevator suddenly stops and the car is trapped? A: Press the "emergency call button" in the car promptly to contact the elevator management unit. If no one answers, call the emergency rescue number of the maintenance unit posted in the car and wait for rescue.

Please remember: the car is a ventilated and safe space, and trying to "escape" the car to save yourself is often a dangerous choice. Q: Why does the elevator suddenly fall? What should I do when it falls? A: The working principle of the elevator. In layman's terms, several traction wire ropes are connected to the car through the traction sheave at one end, and the counterweight device at the other end. The gravity of the car and the counterweight device presses the traction wire ropes against the traction sheave groove. Friction is generated inside, the motor rotates, driving the traction wheel to rotate, and the friction drives the wire rope, dragging the car and the counterweight to move up and down relative to each other.

In order to prevent the elevator from overspeeding upward or downward, the elevator is equipped with multiple mechanical and electrical safety protection devices such as brakes, speed limiters, safety gears, upward overspeed protection devices, upper and lower limit switches, and buffers. When an abnormality occurs in the elevator, these protection devices will act and stop the elevator.

Once the car falls at excessive speed, the speed limiter will activate the safety gear and stop the car on the track. Sometimes, due to signal loss, insufficient traction, brake wear and other reasons, the elevator cannot stop at the corresponding floor, causing slippage and misalignment, making people feel that the elevator is falling out of control.

In fact, the extreme situation of simultaneous failure of multiple mechanical and electrical safety protection devices is almost impossible to occur. Therefore, the elevator will not fall in a free fall. If you feel the elevator suddenly drops while riding, you can quickly press the buttons on each floor, stand firm, support yourself, and maintain your body balance to prevent falling.

Q: Will an accident occur if the car shakes when the elevator is running? A: The elevator sometimes shakes due to wear of the guide rails, excessive clearance between the guide shoes and the guide rails, uneven tension of the wire ropes, etc. Do not panic when encountering such a situation, as no accident will occur. If you want to reduce shaking, you can ask the maintenance department to adjust and repair elevator-related components.

Q: Use your hands or for a long time.

7. Safety Lesson Plan: How to rescue yourself if trapped in an elevator

If you are trapped in an elevator

●The last thing you need to worry about is that the elevator rushes to the top or falls!

Modern elevators are equipped with safety protection gears. Even if there is a power outage, this safety device will not fail. Once something goes wrong with the elevator, this pair of protective clamps will firmly clamp the rails on both sides of the elevator slot to prevent the elevator from falling or rushing to the top. The thrilling scene of the sudden rise and fall of the elevator performed in the movie has almost zero possibility of happening in real life.

●The most likely place for accidents is the elevator door!

Dangerous Behavior 1: After being trapped in the elevator, open the elevator door and climb out of the elevator by yourself.

Modern elevators have computer error correction functions. They will automatically start working after a fault occurs. The key is that it is likely to successfully correct the error and start suddenly when you open the door and climb halfway out. There were two typical incidents like this last year, resulting in one death and one injury. The deceased was cut off at the waist when the elevator started when he climbed out of the door. Another injured person had both of his feet amputated. Therefore, it is extremely dangerous to open the elevator door. It is better to calm down and wait for rescue.

Risky Behavior 2: Habitual Behavior When Entering and Exiting the Elevator

Each elevator door has two layers, so you should pay special attention when entering and exiting the elevator. A 17-year-old girl from Hangzhou , while waiting for the elevator, she was holding on to the outer box door. At this time, the elevator door suddenly opened and the girl fell directly into the elevator shaft.

There is also a possibility that the elevator stops and opens the door before it reaches the floor. At this time, some habitual behaviors (such as chatting, talking on the phone, reading the newspaper you just got back) will make you neglect and take one more step. He fell into the gap between the car and the elevator shaft.

Dangerous behavior 3: Climb out of the emergency exit in the elevator

As soon as the exit panel is opened, the safety switch will stop the elevator. However, if the exit panel is accidentally closed, the elevator may suddenly Start, making people lose their balance. In a dark elevator shaft, you may trip on the elevator cables or slip on the sludge and fall.

"The best way to protect yourself when the elevator falls"

First, (no matter how many floors there are) press the buttons on each floor quickly.

Second, if there is a handle in the elevator, hold the handle tightly with one hand.

Third, the entire back and head should be close to the interior wall of the elevator, forming a straight line.

Fourth, the knees are bent.

Explanation: Because when the elevator falls, you don’t know when it will hit the ground, and you are likely to break your body and die when it falls.

So:

The first point is that when the emergency power is activated, the elevator can stop immediately and continue to fall.

The second point is to fix your position. seat, so that you will not fall due to unstable center of gravity

The third point is to use the elevator walls as spine protection

The fourth point is the most important reason Ligaments are the only tissue in the human body that is rich in elasticity, so bending the knee to bear the pressure of a heavy blow is greater than bones bearing the pressure.

Actually on Monday The elevator was not very good at that time. The steel wires rubbed against the electric wires. Fortunately, I saw it in advance and didn't dare to sit on it. It was repaired later and I didn't care.

I wanted to go to the third floor in the afternoon, but I didn’t expect that the elevator stopped moving halfway to the second floor. The floor display displayed garbled numbers and kept jumping. I was the only one! Xiao was nervous for a moment, remembering the time when he was locked in the elevator of the basic department at school, but after all, A Jian was still there at that time.

Fortunately, the floor is not high. The self-rescue plan is as follows for your reference:

1. I have tried all the buttons, but they are all in vain, and the garbled characters are still flashing wildly.

2. I opened the small debugging panel and tried it. Pressing the "slow up" and "slow down" buttons were useless. Now that I think about it, I was really scared to press them blindly...

< p> 3. I can only make phone calls, but there is no one in the office.

4. I wanted to shout, but I was afraid of alerting Bangbang and Sister She who came to inspect. It would not be fun for them to see me trapped in the freight elevator.

5. Forcibly opened the door a small crack. When there were various wires and pipes in front of me, I didn't dare to move and closed it again, hehe.

6. Now comes the difficult part. Press and hold "2" with your left hand and push the elevator door to the right with your right hand so that it can open to the second floor.
