The phenomenon of failure of escalators due to foreign objects is not an isolated case. Reporters searched the network and found that in 2015, the step pedal of an escalator in a shopping mall in Yizheng, Jiangsu suddenly collapsed. Coins or other foreign bodies were stuck, causing the step pedal to squeeze against the comb plate. The displacement of the comb plate touched the safety protection switch and the elevator stopped running. In 2017, the comb plate of the upward escalator of a supermarket in Hangzhou was jammed by foreign bodies, causing the steps to shift and a collision between the steps and the comb plate. In 2023, A female passenger accidentally stuck her skirt on the comb board while riding the escalator......

The reporter learned that a small coin, a small nail or a small button, when they become a foreign body stuck in the escalator, may have a very big impact. These foreign objects are usually stuck at the position of the comb plate (I. e. the connection between the pedal and the elevator) at the entrance or exit of the escalator. If the foreign objects are hard or sharp nails, buttons, etc., the escalator will have obvious abnormal noise.

Guangzhou Metro specially reminds: there are gaps between escalator steps and steps, between steps and skirt boards on both sides. Pay special attention when taking the escalator. Don't lean against the skirt boards on both sides. Passengers wearing loose clothes should pay attention to the trouser legs or skirts, fold them up or lift them up slightly, and don't be close to the baffle boards on both sides of the escalator to avoid being involved in the gap. Passengers with luggage cases should put them firmly and hold them when taking the ladder. Pay attention to the wheels of the luggage cases when going up and down the escalator to avoid any danger.

If the escalator is found to be clamped, please shout loudly to remind the personnel on the escalator to stand firm and hold it well, and press the "emergency stop" button of the escalator at the first time to stop the escalator.

It is hot and rainy in summer in Guangzhou. Passengers wearing sandals should pay attention when taking the escalator. Do not put their feet close to the junction of the steps and the guard plate (pay special attention to children) to prevent the shoes from being involved when the escalator is running. When entering and leaving the escalator, pay attention to striding to prevent toes from kicking the pedals of the escalator and the edge of the ladder platform.
