Design and Development of a UVC Ray Disinfection System for Personal Protective Equipment in High-Demand Facilities
(Springer Science and Business Media Deutschland GmbH, 2025)
Since the latest pandemic, there is an increased demand for personal protective equipment (PPE) such as N95 masks, creating shortages. As a result, the need arises to disinfect and reuse PPE, with UVC ultraviolet radiation being a promising method. The objective was to design and build UVC disinfection equipment for N95 masks that guarantees their effective reuse. A prototype was made for biological validation with Bacillus subtilis and microscopic analysis of fibers in 3 cycles of 5 min of UVC. The final equipment for 32 masks was then built in 5 min according to validated parameters. The results showed that 5 min of UVC significantly reduced the microbial load without affecting the masks. Repetitive irradiation should not exceed 3 cycles. It is concluded that functional equipment was obtained whose parameters guarantee the effective disinfection of N95 masks in the face of the health emergency.
