Chapter 2: How the Brushes Improve Safety
The primary purpose of escalator brushes is behavioral rather than mechanical. When a rider's shoe or clothing touches the brushes, the sensation encourages them to move slightly toward the center of the step.
This gentle contact acts as a warning system. The brushes create a physical reminder that passengers should avoid standing too close to the sides.
Safety specialists have long recognized that people often drift toward escalator edges without realizing it. Children, in particular, may place their feet near the sides while looking around or playing. The brushes help draw attention to proper positioning before a problem develops.
By encouraging riders to remain centered, the brushes reduce the likelihood of loose clothing, long shoelaces, bags, or other items coming into contact with areas where movement occurs.
