Elevator ride safety knowledge

1, the emergency stop button can help.

The emergency stop button is usually under the escalator running indicator light. Once the passenger upstream of the escalator falls, the passenger closest to the "emergency stop button" of the escalator can immediately press the button, and the escalator will stop slowly and automatically within 2 seconds. The rest of the passengers should also keep calm and hold on to the handrails. Follow-up passengers should not be onlookers, but should help the passengers involved accurately and quickly.

2. The escalator bite has nothing to do with the weight.

The moving parts of escalator mainly include handrails and steps. Compared with fixed parts, these moving parts have higher risk factors. The damage of handrails does not depend on the weight, even if adults hold on to handrails and don't let go, they can take them off. Escalator accidents often happen to children, because they are young, curious and playful, and they can't take timely and accurate actions when accidents happen.

3, stepping on the yellow warning line is easy to be "bitten"

A yellow line is drawn at the front and back of each step. Many people only know that this warning line is to remind everyone to avoid stepping on the wrong steps. In fact, there is a key structural part in the yellow painting part, called the comb plate, which is responsible for the engagement of the upper and lower steps. As the name implies, one side of the comb plate is like a tooth, with protrusions and grooves.

The gap between the teeth of the comb plate is clearly stipulated in the country, and it is required to be around1.5 mm. When the comb plate is intact, this gap is very safe. However, with the increase of elevator service time, the comb plate loses its teeth, just like a tooth in the mouth, and the alveolar gap becomes larger, making it easier to get stuck in food. The gap between the two teeth increases, and the risk of being "bitten" into the escalator increases when the upper and lower steps bite.

4. The gap between the skirt and the steps is the most dangerous place.

When the escalator is running, the steps move up or down to prevent people from falling out. The fixed part is called apron. The state clearly stipulates that the sum of the gaps between the left and right skirts and the steps shall not exceed 7 mm. When the escalator just leaves the factory, this gap is in line with national standards.

However, the escalator will wear and deform after running for a certain period of time. At this time, the gap between the skirt and the step may become larger. If it is close to the edge, it is easy to rub the shoes against the apron board, and the shoes are likely to roll into this gap under the action of friction. The joint between the steps and the ground is equally dangerous, and the soles of children's shoes may be caught in gaps or even toes.

5, escalator safety blind area

Professionals point out that the area with "2" in the figure below is a safety blind zone, and the areas with "1" and "3" are safe, remember that the second one is the most dangerous! You can step on the first and third blocks, but don't step on the second block, because the bottom is empty and easy to get involved. Be careful when taking the elevator.

6. Escalators like to "bite" these shoes.

Cave shoes

According to a survey, the frequent elevator "biting" incidents are mostly caused by children wearing soft foam shoes. The hole shoes are made of polyethylene resin, which is soft in texture and good in anti-skid performance, and it is easy to get stuck in transmission equipment such as escalators. When an accident happens, it is often difficult for a child with little strength to move his shoes.

Lace shoes

Shoelaces are easy to fall into the cracks of elevators, and then some shoes are brought in and caught on the toes. Before taking the escalator, parents who wear lace-up shoes should pay attention to whether they and their children's shoes are fastened. If you are caught, you must call the police for help in time and ask people at both ends to press the "stop" button as soon as possible to avoid further injury.

open toed shoes

The child's movements are not flexible and coordinated, and his eyesight is not accurate. Wearing open-toed shoes greatly increases the possibility of foot injury. When you take the elevator, you may bump into the elevator on the next floor and kick your toes because of improper timing. Therefore, when parents buy sandals for their children, it is best to choose the style of foot binding.

Matters needing attention in taking the escalator

1. Before going up the escalator, be sure to see the running direction clearly and be careful when stepping into the elevator.

2. Don't take the escalator barefoot or with loose shoes. When wearing a long skirt or carrying articles on the escalator, please pay attention to the skirt and articles to avoid being caught.

3. When entering the escalator, don't step on the junction of two steps, so as to avoid falling down due to the height difference between the front and rear steps when the escalator runs to the inclined section.

4. When riding the escalator, hold the handrail tightly, and keep your feet firmly on the steps to avoid standing near the stairs. Stretch the child with your hands or grab small objects that are easy to fall.

5. Don't lean on the sides of the escalator or the handrail, which is easy to be brought down; Don't run on the escalator because you are in a hurry, which will not only increase the chance of falling, but also easily lead to escalator failure.

6. When there is an emergency on the escalator and the passenger in front falls down carelessly, you can hold the handrail with one hand and hold it with the other hand to prevent it from falling down, and call for help at the same time. There are "emergency stop" buttons at the beginning and end of the escalator. When the elevator encounters an emergency, the staff or passengers can press the button to brake the elevator.

7. If you can't press the emergency stop button at the first time, passengers should hold the handrail of the escalator tightly with both hands, and then lift their feet so as not to touch the escalator, so that people will move with the guardrail of the escalator and won't fall, but there is a premise that there can't be too many people on the escalator.

8. If you accidentally fall down on the escalator, cross your hands and fingers, protect the back of your head and neck, elbow forward and protect your temples. Because the strong impact on the neck will damage the nerves, which will easily lead to paralysis and life-threatening in severe cases.

Popular science of elevator safety knowledge

1. How does the elevator work?

Answer: The elevator has a car and a counterweight, which are connected by wire rope. The steel wire rope is driven by the traction of the driving device (traction machine), which makes the elevator car and counterweight move up and down on the guide rail in the elevator.

2. Will the steel wire rope of the elevator break?

Answer: The wire rope elevator for elevator is special, and the state has special regulations and requirements. The configuration of wire rope should not only bear the elevator car and rated load, but also consider the traction. Therefore, the tensile strength of wire rope is much greater than the load of elevator, and its safety factors are all above 12. Generally, elevators are equipped with more than four wire ropes, and the wire ropes of an elevator will not be completely broken at one time.

3. Is there any danger of sudden power failure during elevator operation?

Answer: In case of sudden power failure or power supply line failure during elevator operation, the elevator will automatically stop running without any danger. Because the elevator itself is equipped with electrical and mechanical safety devices, once the power fails, the brakes of the elevator will automatically brake, making the elevator unable to operate. In addition, if there is a planned power outage, the power supply department will notify in advance and the elevator may stop running in advance.

4. What if the elevator suddenly speeds up?

Answer: The running speed of the elevator, whether ascending or descending, should be within the specified rated speed range, and generally it will not exceed the speed limit. In case of overspeed, there is an anti-overspeed device in the elevator control system. At this time, the device will automatically act to slow down or stop the elevator.

5. Can the overload of elevator car be automatically controlled?

Answer: The load capacity of the elevator varies according to the needs. The elevator can only run within the specified load. When the load is exceeded, the elevator will automatically give an alarm and cannot run.

6. Will it hurt people to be caught when the elevator is closed?

Answer: When the elevator is closed, if the car door touches people or things, the door will automatically reopen without hurting people. Because there is a switch on the door to prevent family members, once the door touches people or things, this switch action makes the elevator unable to close the door, reopen the door and then close it. In addition, the closing force is specified by and will not reach the level.

7. Can the elevator door be opened?

9. Are there any protective measures for the bottom squat of the elevator?

Answer: When the elevator squats on the bottom floor, the elevator car will cross the first floor and travel down until it squats on the buffer in the pit. Buffers are protective devices for this purpose. According to the different running speed of the elevator, this protection device can be divided into spring type and hydraulic type. A car lying on the bumper is called squatting. At this time, the buffer can reduce the impact of the elevator car, so as not to cause serious harm to the passengers in the elevator.

10. The elevator is not working properly. What should I do in the car?

Matters needing attention in elevator use

1, pay attention to the overload elevator. When the elevator gives an alarm, you should take the initiative to quit and wait for the next trip. It is very dangerous to overload the elevator.

Don't block the elevator door. When the elevator door is about to close, don't rush into the elevator to prevent the elevator from closing.

3, avoid one foot inside and one foot outside, you will get hurt.

4. Don't just press panic button. Panic button was set up to cope with unexpected situations. Never press panic button when the elevator is running normally, otherwise it will bring you unnecessary trouble.

When taking the elevator, if the elevator door is not closed, it will run, indicating that there is something wrong with the elevator. Passengers should not take it and report to the maintenance personnel at the same time.

6. Before coming to the elevator, passengers should first check whether there is a sign of "Elevator Stop Maintenance". If the elevator is under maintenance, this sign should be hoisted and passengers are not allowed to ride.

7. In case of fire, the driver or passenger should park the elevator on the floor where the fire or fireworks have not spread. Passengers are forbidden to use the elevator to escape, and should escape from the stairway safety exit.

8. In case the elevator breaks down during operation, passengers should not panic. They should press the walkie-talkie or alarm button to inform the maintenance personnel to rescue, and don't press it indiscriminately. Waiting is a wise choice to ensure safety.

9. After the elevator stops, passengers should pay attention to whether the floors of the elevator car are level when entering and leaving the elevator. If it is uneven, it means that there is something wrong with the elevator. They should inform the maintenance in time to ensure the safety of passengers.
