Safety knowledge of elevator ride

1. The emergency stop button can save lives

The emergency stop button is usually under the running indicator light of the escalator. Once the passenger upstream of the escalator falls, the passenger closest to the "emergency stop button" of the escalator can press the button immediately, 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 watch and help the passengers involved accurately and quickly.

2. The "biting" of the escalator has nothing to do with the weight

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

3. Stepping on the yellow warning line is easy to be "bitten"

A yellow line is painted at the front end and the back end 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 paint brushing part, called the comb plate, which is responsible for the meshing of the upper and lower steps. As the name suggests, one side of the comb plate is like a tooth, with protrusions and grooves.

The clearance between teeth of the comb plate is clearly stipulated by the state, and it is required to be about 1.5mm.. When the comb plate is intact, this gap is very safe, but with the increase of elevator service time, the comb plate loses its teeth, just like a tooth in the mouth, and the alveolar space becomes larger, which makes it easier to get stuck in food. The gap between the two teeth increases, and when the upper and lower steps are engaged, the risk of being "bitten" into the escalator also increases.

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

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

however, the escalator will be worn and deformed after running for a certain period of time. At this time, the gap between apron board and steps may become larger. If it is close to the edge, it is easy to rub shoes against apron board, and shoes are likely to be rolled 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 the gap and even pinch their toes.

5. Safety blind area of escalator

Professionals pointed out that the area marked with "2" in the figure below is a safety blind area, and the areas marked with "1" and "3" are safe, so 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, so be careful when taking the elevator.

6. Escalators like to "bite" these shoes.

Hole shoes

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

lace-up shoes

The shoelaces are easy to fall into the gap in the elevator, and then part of the shoes are brought in and caught on the toes. Before riding the escalator, parents who wear lace-up shoes should pay attention to whether they and their children's shoes are fastened. In case of being caught, be sure to call 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

Children's movements are not flexible and coordinated, and their visual acuity is not accurate. Wearing open-toed shoes greatly increases the possibility of foot injury. When taking the elevator, you may run into the elevator at the next higher level and kick your toes because of improper timing. Therefore, when parents buy sandals for their children, it is best to choose the style that wraps their feet.

Precautions for taking the escalator

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

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

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

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

5. Don't lean on both sides of the escalator or on 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. In case of an emergency on the escalator, when the passenger in front accidentally falls down, you can hold the handrail with one hand and hold the other hand to keep it from falling down, and at the same time call for help. 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 make the elevator brake.

7. In case the emergency stop button can't be pressed for the first time, the passenger should hold the handrail of the hand-held elevator tightly with both hands, and then lift his feet so as not to touch the hand-held elevator, so that people will move with the guardrail of the hand-held elevator and won't fall down, but there is a premise that there can't be too many people on the elevator.

8. If you accidentally fall down on the escalator, you should cross your hands and fingers, protect the back of your head and neck, and put your elbows forward to protect your temples. Because a strong impact on the neck will damage the nerves, which is easy to cause paralysis and life-threatening in severe cases.

popularization of elevator safety knowledge

1. How does the elevator work?

a: the elevator has a car and a counterweight, which are connected by a steel wire rope, which is driven by the traction of the driving device (traction machine) to make 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?

a: the wire rope elevator used for elevators is special, and the state has special regulations and requirements. The configuration of wire ropes is not only to bear the elevator car and rated load, but also to consider the size of traction. Therefore, the tensile strength of wire ropes is much greater than the load of elevators, and their 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?

a: 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 run. In addition, the power supply department will notify in advance if there is a planned power outage, and the elevator may stop running in advance.

4. what should I do if the elevator suddenly speeds up?

a: whether the running speed of the elevator is up or down, it should run within the specified rated speed range, and generally it will not overspeed. If overspeed occurs, 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 capacity. When it exceeds the load capacity, the elevator will automatically give an alarm and cannot run.

6. Will being caught when the elevator closes cause harm to people?

a: when the elevator closes, 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 it and then close it again. In addition, the closing force is stipulated by and will not reach the level.

7. Can the elevator door be opened?

a: the elevator door can't be opened outside the hall, and it can only be opened with special tools (the special tools are mastered by maintenance personnel). Passengers are not allowed to pry the door, let alone open it, otherwise there will be a danger of falling into the shaft.

8. how to call the elevator?

a: when you need to take an elevator, you should select the direction button you want to go to on the floor of the elevator hall. Press the up direction button up and press the direction button down. The elevator stops in the forward direction in the control system. If the elevator stops in the reverse direction, it will not stop at this floor.

9. Are there any protective measures for the bottom squatting and the top rushing of the elevator?

a: when the elevator squats at the bottom, the car of the elevator will go beyond the first floor flat position and go down until it squats on the buffer of the pit. Buffer is a protective device for this purpose. According to the different running speed of elevator, this protective device is divided into two types: spring type and hydraulic type. When the car squats on the bumper, it is called squatting. At this time, the buffer can alleviate the impact of the elevator car, so as not to cause serious harm to the passengers in the elevator.

1. What should I do in the car when the elevator is not working normally?

a: when you take the elevator, you should press the red emergency stop button on the control panel and the elevator will stop automatically, and notify the elevator maintenance personnel in time.

11. What should I do if I find an odor in the elevator car?

a: when you find abnormal burnt smell in the elevator car, you should press the red emergency stop button on the control panel to stop the elevator, and notify the elevator maintenance personnel in time.

12. What should I do when I find abnormal vibration and scraping of the elevator?

a: when you are riding the elevator and find that the elevator is experiencing abnormal vibration, jitter and scraping, you should press the red emergency stop button on the control panel to stop the elevator and notify the elevator maintenance personnel in time.

13. What should I pay attention to when the elevator suddenly loses power or breaks down and is trapped in the car?

a: when you are locked in the car, you should follow the instructions of the elevator maintenance personnel, and you can contact the relevant personnel through the communication device to rescue you. Never slam the door or jump out by yourself to avoid danger.

14. What should I pay attention to when entering the car?

a: when you enter the car, if the elevator door is open, you should check whether the elevator is on the flat floor or whether the car is on this floor, especially when the light is not clear at night, otherwise it may cause injury and get out as soon as possible.

15. Should elevator installation and repair units and maintenance and operation personnel obtain corresponding qualifications?

a: yes. Elevator installation, maintenance and renovation units shall obtain the qualification certificate issued by Shunde Municipal Bureau of Quality and Technical Supervision before they can engage in the corresponding work; Elevator installation, maintenance, elevator operators should obtain special personnel operation certificate, show certificates.

16. What emergency can I call 11 in the elevator?

a: when there is an emergency in the elevator, people can be injured or trapped (people are trapped in the elevator car and can't find elevator maintenance personnel), and they can call 11.

17. under what circumstances can the elevator complain about quality or safety?

Answer: When the elevator is often closed, jammed, uneven floor, rushed to the top, squatted at the bottom, the driver or maintenance personnel of the elevator has no work license, the driver often leaves his post, the inspection certificate in the elevator car has no expired certificate, the elevator has abnormal noise or sound, abnormal vibration or jitter, the elevator car has abnormal burnt smell, the elevator speed is too fast or too slow, the maintenance is not timely, and there is no communication or alarm device in the elevator car.

18. What should I say when I call the police or complain about the elevator?

answer: the specific situation of the elevator should be clearly stated, and the specific location of the elevator, the contact person and telephone number of the property right unit and the responsible department of the elevator, the maintenance unit and telephone number of the elevator should be clearly stated.

Precautions for elevator use

1. Pay attention to the overload and overload of the 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.

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

3. Avoid staying with one foot inside and one foot outside, which will hurt you.

4. Don't press the panic button casually. The emergency button is set to cope with unexpected situations. When the elevator is in normal operation, never press the emergency button, otherwise it will bring you unnecessary trouble.

5. When taking the elevator, if the elevator door is not closed, it will run, which means 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 "Stop Elevator for Maintenance". If the elevator is under maintenance, this sign should be hung and passengers should not take it.

7. In case of fire, drivers or passengers should park the elevator on the floor where the fire or fireworks have not spread. Passengers are forbidden to use the elevator to escape, but should escape from the safety exit of stairs.

8. In case of trouble during elevator operation, passengers should not panic. They should press the intercom button or alarm button to inform the maintenance personnel to rescue them. 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 floor and floor of the elevator car are level when entering or leaving the elevator. If it is uneven, it means that there is something wrong with the elevator, and they should notify the maintenance in time to ensure the safety of passengers.
