A professor at the University of Waterloo is drawing on two decades of research into disinfection using ultraviolet (UV) light to help solve a shortage of masks for front-line healthcare workers in the COVID-19 crisis.
Bill Anderson, a professor of chemical engineering, has consulted with officials at several hospitals in southern Ontario as they explore ways to reuse N95 respirators instead of throwing them out after each use.
“At this point, in Canada at least, people are looking at it as a Plan B in case they run out of masks,” he said.
Two University of Waterloo facilities have shifted their production focus to 3D-printed parts for face shields used by health-care workers battling COVID-19.
3D printers in the Multi-Scale Additive Manufacturing (MSAM) Laboratory and in the Print and Retail Solutions Department at the University are being used to build certified pieces of the protective equipment from a special material currently in short supply throughout the local medical community.
