What’s this that you always see on a escalator? Seems kinda pointless

Escalators are a ubiquitous part of modern infrastructure, seamlessly transporting people between floors in malls, airports, and other public spaces. While most people are familiar with the basic function of an escalator, there are several features that often go unnoticed. One such feature is the brush-like strip that runs along the sides of the escalator steps, known as the skirt brush. At first glance, these brushes may seem like a minor or even pointless addition, but they serve a critical role in the safe and efficient operation of escalators.

Understanding the Purpose of Escalator Skirt Brushes

The primary purpose of escalator skirt brushes is to act as a safety feature. These brushes are strategically placed to prevent objects, clothing, or body parts from getting caught in the gap between the moving steps and the stationary side panels, known as the skirt. By providing a tactile barrier, the brushes discourage passengers from standing too close to the edges, thereby reducing the risk of entrapment and injury.
