Healthcare workers turn to UV radiation to disinfect PPEs in Coronavirus battle

Personal protective equipment (PPE), including N95 masks and gloves, continue to be scarce across the healthcare industry as hospital workers use it to shield themselves from the novel coronavirus.

And some hospitals are now turning to ultraviolet radiation to help disinfect available medical equipment to prolong their use.

The shortage of PPEs has led a team at Nebraska Medicine to develop a process that allows for the decontamination and reuse of N95 masks. The procedure entails delivering high doses of “ultraviolet germicidal irradiation” (UVGI) to the used masks.

“The UVGI exposure we have chosen exceeds, by at least several folds, the amount of exposure needed to inactivate SARS-CoV-2 and provides a wide margin of safety for surface decontamination,” the team’s report noted.

N95 masks are also being reused at Saint Louis University Hospital in St. Louis. After being exposed to UV light for 10 minutes, the mask can be used for up to five more shifts. The crew is capable of sanitizing as much as 1,600 N95 masks per day.

“We believe a variety of UV light sources could be used similarly, including UV-equipped biosafety or sterilization cabinets or other UV disinfection systems,” the report wrote. Nebraska Medicine’s report added that the same method can be applied to a variety of other critical items, such as procedure masks.

Dr. Jeremy Rossman of Kent University in the United Kingdom told AccuWeather that UV light is powerful at destroying the genome of viruses and sterilizing surfaces in laboratories.

The new study Far-UVC (222 nm) efficiently inactivates an airborne pathogen in a room-sized chamber was conducted by scientists at the University of Dundee, University of St. Andrews, Columbia University, and the University of Leeds, and it was published in Scientific Reports.

According to the study author Professor David J. Brenner, the far-UVC can reduce the number of active microbes in the indoor air to almost zero, making the air indoor is safe as the outdoor air.

Prof. Brenner added that using the technology in locations where people gather together indoors could prevent the next pandemic.

The far-UVC light is simple to install. It is not expensive. It does not need people to make any changes to their behavior. It is also a safe way to prevent the transmission of any virus, including the COVID virus its other variants. It can also prevent the transmission of influenzas and other potential pandemic viruses.

The use of Care222 in public places is a safe and effective way to limit the spread and transmission of air-mediated microbial diseases, such as schools, hospitals, stadiums, sports grounds and offices, and this approach may help to limit seasonal infections, the spread of tuberculosis and major epidemics. It’s inevitable far uvc will become part of the new World people are more aware and want to be protected from viruses.

Care222 is a new disinfecting light source that, even though not harmful to the skin or eyes of humans or animals, deactivates bacteria and viruses in the same manner as conventional ultraviolet sanitizers.

Care222 uses an excimer lamp (a mercury-free UV excimer light source produced by Ushio especially for outputting monochromatic ultraviolet with a primary wavelength of 222 nm) in combination with a special optical bandpass filter (200 to 230 nm) which passes only ultraviolet wavelengths that have no harmful effect on people.

Ushio holds exclusive rights to utilization of the key technology, which was patented by Columbia University (New York, NY) in 2012.

Only 222 nm, which is filtered by a special optical bandpass filter for the rest of the harmful wavelengths, is safe for humans.
