纽约公交将采用紫外线灯杀新冠病毒

纽约市公共交通管理部门宣布将在一个试点项目中采用紫外线灯来杀死公交车、地铁和车站的新冠病毒。

The agency in charge of public transit¹ in New York City announced a pilot program using ultraviolet light lamps to kill Covid-19 on buses and trains and at stations.

 

The Metropolitan² Transportation Authority said Tuesday night that it will use "150 dual-headed mobile devices" from Denver-based start-up PURO Lighting³ to determine the efficiency and cost-effectiveness of the UVC light technology, the agency said in a press release.

 

UVC, which is one of three types of light on the UV spectrum⁴, is proven to eliminate Covid-19 and is most potent⁵ against viruses and bacteria, PURO Lighting said. PURO noted⁶ that their lamps also have UVA and UVB as well for full spectrum disinfection.

 

The first phase is set to launch on subways and buses and at transit facilities by early next week, the MTA said, and if successful will expand to Long Island Rail Road and Metro-North Railroad trains in a second phase. The two railroads serve New York City's suburbs.

 

The lamps will be used during the overnight shut down on subway trains and periods where transit is out of service.

 

For the first time in its 115-year history, New York City deliberately⁷ shut down its entire subway system overnight starting May 6 to clean all its cars.

 

The MTA touts⁸ that UVC light is "an efficient, proven, and effective technology for eliminating viruses, including SARS-CoV-2 that causes COVID-19" and has been demonstrated to kill viruses in hospital operating rooms, urgent care clinics, universities, and fire stations. The first phase will focus on the rolling stock of cars, stations and yard areas, the MTA said, as well as occupational facilities, crew rooms and other shared areas.
