Why do Escalators have Brushes at the bottom of the side Walls?

The double layer nylon brushes along the skirts of escalator ensures a safer ride. When bristles of these nylon brushes touch the passenger they instinctively move to safer distances. These brushes help the passengers know that they are on the very edges of escalators which may result in pinching and entrapment. It also tend to keep clothing, luggage or loose clothe away from the skirts. These nylon brushes are durable hence these come as less expensive safety option. Escalator brushes are installed on the sides of escalators and moving walkways to keep people from standing too close to the edges. Loose, low-hanging clothing, shoelaces, soft-soled shoes, and other such items are at risk for becoming caught in the moving track or moving stairs, so these brushes are designed to provide a gentle reminder for people to stand at a safe distance from the moving edges.
