Some netizens support the practice of "walking left and standing right".
Some netizens believe that this practice is dangerous.
Some netizens said that they generally choose to take the stairs.
In many places, the "left-to-right" initiative has been cancelled
In recent years, Beijing, Shanghai, Guangzhou, Nanjing, Hong Kong and many other places have canceled the "left-to-right" initiative. In 2019, Shanghai Metro also issued the "Latest Version of the Escalator Instructions", canceling the previous advocacy of "walking on the left and standing on the right", and adding "prohibiting walking and running while taking the escalator".
In addition, according to the operation data of Nanjing Metro Operating Company, the long-term "left and right" damage to the elevator is great, and 95% of the elevator damage is caused by the uneven force of the elevator.
Why is it not suitable to move around when riding an escalator?
According to the current national standard (GB16899-2011), the step height of the escalator is generally 21cm, and the highest shall not be greater than 24cm, which is 13cm-18cm higher than the design height required for stairs in public places; In addition, according to the regulations, the step depth of the escalator cannot be less than 38cm, which is much higher than the minimum requirement of 22cm for the tread width of ordinary stairs.
In addition, the speed of the elevator in the mall is generally 0.5 meters per second, while the elevator speed in the subway is a little faster, about 0.65-0.7 meters per second, which belongs to the "high-speed elevator".
From the perspective of the design principle of the escalator, the slope of the escalator is a little higher than the height of the stairs of the daily building mechanism, which is not suitable for walking.
Expert: Just stand firm when you sit on the escalator
Wu Bin, an elevator expert and senior engineer, said that the "left and right" method will produce balance deviations, resulting in a lighter load on the "left" side of the elevator and a heavier load on the right, which will cause tilting.
Therefore, when taking the escalator, you only need to stand firm and hold it up, and passengers who are in a hurry need to pass safely and quickly, the best way is to take the stairs.
Take the escalator
Please stay away from these dangerous movements

Dangerous areas that are prone to "bite".
Be sure to pay attention when riding the escalator
Some moves are very dangerous
↓↓
- The apron board, handrails, comb belts, and staircase gaps of the escalator are all dangerous areas to pay attention to;
- Do not lean on the side of the escalator apron panel;
- Do not let your hands, feet, and the hem of your clothes get close to the elevator cracks to avoid pinching accidents;
- Don't walk or run briskly on the steps, and don't go against the grain;
- Do not lean out of the handrails to prevent collisions or falls;
- Do not insert sharp and hard objects such as crutches into the gaps or grooves of the elevator;
- Do not climb on handrails or inner and outer covers;
- When exiting the escalator, do not stop at the exit of the escalator to talk or look around to avoid colliding with people behind you.
Sudden escalator accident
How to deal with it correctly?
- Shouting for help and reminding others to press the emergency stop button as soon as possible;
- If the escalator suddenly stops or goes in the opposite direction, quickly grasp the handrail to prevent falling, communicate loudly with the people around you, and avoid crowding and stampeding;
- In the event of a fall, it is best to interlock the fingers of the hands to protect the back of the head and neck, and the elbows forward, and protect both temples to prevent fatal injury.
