Escalators are a familiar sight in malls, airports, and other public spaces, efficiently moving people between levels. While their function seems straightforward, certain components—such as the brushes along the sides—often go unnoticed or misunderstood. These skirt deflector brushes are not decorative elements but essential safety features designed to prevent accidents.
What Are Escalator Brushes?
The brushes lining the edges of escalators, known as skirt deflector brushes, are positioned where the moving steps meet the stationary side panels (the “skirt”). Their primary function is to enhance passenger safety by preventing accidents caused by entrapment in this narrow gap.
Why Are Escalator Brushes Important?
The space between the escalator steps and the skirt poses a potential risk. Loose clothing, shoelaces, and even body parts can get caught, leading to serious injuries. Skirt deflector brushes serve multiple safety purposes:
- Preventing Entrapment: The bristles create a physical barrier that helps keep objects away from the dangerous gap.
- Providing Sensory Feedback: If a passenger stands too close, the brushes touch their shoes or clothing, serving as a reminder to step away.
- Discouraging Unsafe Behavior: Their presence deters people from intentionally placing items near the skirt, reducing misuse and accidents.
How Do They Work?
Skirt deflector brushes are made from durable, flexible synthetic bristles that can withstand constant use. They run along the entire length of the escalator’s skirt panel, providing continuous protection without interfering with the escalator’s function or passenger movement.
Common Misconceptions
Many people mistakenly believe that these brushes are meant to clean shoes as they ride the escalator. This misunderstanding can lead to unsafe behavior, such as deliberately rubbing footwear against the bristles, which increases the risk of entrapment rather than preventing it.
The History of Skirt Deflector Brushes
The addition of these brushes became widespread after safety studies highlighted the dangers of the step-skirt gap. Regulatory bodies responded by updating escalator safety standards. For example, the British and European standard BS EN115-1:1995 emphasized the importance of skirt deflectors, making them a required feature in new installations and a recommended upgrade for older escalators.
Raising Public Awareness
While safety professionals and engineers recognize the importance of these brushes, many passengers do not. Increasing awareness through signage and public information campaigns can help prevent unsafe behaviors and promote safer escalator use.
Final Thoughts
Escalator brushes may seem like minor design details, but they play a critical role in passenger safety. By preventing clothing and objects from getting trapped in the step-skirt gap, they help reduce accidents and injuries. Understanding their purpose ensures safer escalator use and highlights the thoughtful engineering behind everyday public spaces.
Next time you step onto an escalator, take a moment to appreciate these often-overlooked safety features—they might just prevent an accident.
