You have probably used escalators in shopping malls, train stations, or airports. If you look closely, there are small brushes installed on both sides of these structures. Many people mistakenly believe that these brushes are used to clean dust and dirt from shoes, but this is not the case.
In fact, these brushes are installed as part of the escalator's safety measures. Their main function is to warn people and prevent their shoes, clothing, or other items from getting stuck in the side parts of the escalator.
Escalator stairs are constantly moving, and there is a side panel on both sides. There is a small gap between the steps themselves and this panel. If a person places their foot too close to this edge, part of their shoe or slipper can fall into this open space, creating a risk of injury. Children's shoes, loose clothing, and slippers pose a particular danger as they can get caught in the side parts. The brushes are installed precisely to reduce this risk.
When a person's foot or shoe touches the brush, it gives them a slight sensation, prompting them to move their foot to the center of the step.
Yes, one of the functions of these brushes is to keep people away from the edges of the escalator. However, it should be understood that they are not a solid wall or a guard capable of completely preventing shoes from getting inside. Their main goal is to warn people in advance so that they keep their feet away from the edges.
Always try to stand in the center of the step. Keep your shoes or slippers away from the edges. When boarding an escalator, hold your child's hand. Ensure that loose clothing does not touch the edges of the steps. Running or playing on the escalator should also be avoided. Therefore, the next time you see brushes on the edge of an escalator, do not perceive them as shoe cleaning tools; they are installed for your safety.
