City authorities have already launched the first devices with powerful ultraviolet (UV) lights attached to cleanse the buses, subways and subway stations off of the pandemic virus’s microparticles. The program is being organized by the Metropolitan Transportation Authority, which further plans on launching a hundred and fifty such devices to clean subways and buses as phase one of the program. According to NY1, project expenditure is estimated to be close to USD 1 million. The second phase of this project will be directed towards cleaning and disinfecting the MetroNorth and Long Island Rail-Road commuter trains. The University of Columbia has contributed by theorizing how this system functions and how it could be optimized. The astonishing fact about this program is that this unprecedented step has been taken. The subway is being shut down for a four-hour-window. The devices are then allowed to function and clean the compartments.
The director Columbia University’s Center for Radiological Research, David Brenner, stated: “The UV light that will be used in the current overnight subway and bus disinfection program is very efficient in killing the virus that is responsible for COVID-19.” He further explained that they were simply reducing the chance of infection by destroying viruses in these spaces. The double-headed lamps in the device were purchased from a Denver-based company, Puro lighting, which claims that the light is equipped properly for fighting and disintegrating class 1 and class 2 viruses like the SARS, COVID-19, Ebola, Influenza, etc.
The light used by the lamps (UVC) is said to be extremely harmful to humans who come in direct contact, and therefore, the authorities have put up stringent norms. The UVC is a type of the ultraviolet radiation which has a shorter and more energetic wavelength and is effective in disintegrating virus particles.
