Kept wondering about this, and finally found out the answer 😂😂 Did you know this, or were you also a "shoe-cleaning" believer? 😏😂 They're called "skirt deflectors" — and their main purpose is all about safety. The most important job of those brushes is to gently push your feet, clothing, or even a bag away from the small gap between the moving steps and the stationary side panel. These brushes became a more common safety feature after past incidents, like the King's Cross fire in London. 🚨 Accumulations of dirt and grease inside escalators can be a fire hazard, and the brushes help minimize debris from getting in there and building up. #Escalator #SafetyTips #EverydayWins #MindBlown #Safety
