“Viable SARS-CoV-2 was detected up to 72 hours on stainless steel and plastic. The study also concluded that both SARS-COV-2 and SARS-CoV-1 are more stable on stainless steel and plastic than cardboard and copper. “

To combat the ongoing issues of surface contamination, Cambridge R&D has designed a Self-Sanitizing Door Control System. Cambridge R&D has designed a door opening system that allows door handles and push bars to be disinfected with UVC light between uses. A UVC light source in incorporated right into the door design. The door surface is exposed to UVC light after every use, for both entrance and exit at doorways.
After a person goes through the door, the touched surface is rotated into a chamber that contains the UVC light source, eliminating organisms that reside on the door surface. The cleaned surface can now be rotated back into the opening where the next person entering (or exiting) can engage a clean push bar.
