Safer Alternatives for Disinfection: Improving Safety and Optimizing Disinfection Methods for Non-Critical Surfaces
by Mohamed, Hagir, Ph.D., University of Massachusetts Lowell, 2021, 123; 28153385
Abstract (Summary)

Noncritical surfaces like households and school hallways do not need to be disinfected, however in many cases disinfectants are used on these surfaces in addition to or instead of general purpose cleaners. The concern about excessive exposure to disinfectants is increasing, especially during the current pandemic of COVID-19. Traditional cleaning and disinfecting (C&D) products have been associated with respiratory, dermal, and environmental side effects and bacterial resistance is increasing. Identifying an effective C&D method is also imperative. Following the manufacturer's instructions for C&D products, from ventilation to applying the contact time or dwell time, will enhance the performance and the safety of the C&D product. However, many users fail to follow the instructions properly potentially leading to unnecessary exposure and ineffective disinfection. Therefore, safer disinfectants and optimized disinfection methods are needed. This project's overarching goal is to reduce the use of hazardous traditional disinfectants on noncritical surfaces and replace them with safer alternatives. We tested different C&D products and methods and then applied those methods in female restrooms. Using a less hazardous C&D product such as an all-purpose cleaner and enhancing the mechanism with applying longer contact time, and increasing the wiping cycle strokes is recommended to replace a more hazardous C&D product with one of lesser hazards.
