If you have ever hesitated to touch a well-used escalator's handrails for fear of contracting some disease from the masses, LG Innotek has an answer for you. The company just released a handrail sterilizer that uses UV light to kill nearly every germ coating the rubber belts, according to The Verge.
As the railings move with the escalator, they pass through the UV light, which kills 99.99 percent of germs, according to tech developer LG Innotek. The sterilizer is placed just before escalator users hop on, ensuring the handrails are still relatively clean when you grab on at the bottom. The device is a little bigger than a regular hand sanitizer dispenser (around the size of a piece of paper) and starts automatically when the escalator begins moving. It runs on power generated by the movement of the escalator.
UV radiation is used to kill super-germs in hospitals (and one company wants to bring it to planes), but it's relatively easy to use on your phone, your toothbrush, or anywhere else in your house. You can already get handheld UV sterilizers online, as well as aquarium-specific ones. In April 2017, LG Innotek released a faucet that purifies water by UV-sterilizing it inside the aerator. However, the fact that escalator railings are constantly on the move makes them easier to clean automatically than subway railings, door handles, and other potentially germy public surfaces we touch every day.
Bear in mind that while nobody likes getting a cold, germs aren't always bad for you. Some types can even help protect you against developing asthma, as scientists found while researching the health differences between Amish children and their counterparts on more industrialized farms. Whether you touch the handrails or not, cities have their own unique microbiomes, and those ubiquitous bacteria are pretty much guaranteed to get on you whether you like it or not. On the bright side, if you are a germophobe, UV sterilization has been touted as a possible alternative to other antibacterial treatments that cause supergerms.
