The Battle Against Coronavirus: Surface Disinfection with Electrostatic Sprayers
Friday, January 29, 2021
Surface disinfection is an important strategy in the battle against coronavirus, and it is a strategy that continues to evolve. Commercial cleaning companies are increasingly using an innovative device known as an electrostatic sprayer to ensure quick, efficient coverage by liquid disinfectants on surfaces, especially large areas or intricately shaped surfaces.
Full 360 Degree Coverage
Electrostatic sprayers are designed to quickly achieve complete surface coverage with disinfectants. Sprayed droplets take on a positive charge as they exit the spray nozzle. Because most environmental surfaces have a negative or neutral charge, positively charged droplets of disinfectant are attracted to targeted surfaces. As spraying proceeds, these positively charged droplets repel one another as they impact a given surface, which causes them to spread out and wrap around three-dimensional objects. The result is an even coating of disinfectant, including on hard-to-reach areas.
An August 2020 study published in the American Journal of Infection Control evaluated the application of a dilute bleach solution through an electrostatic sprayer to decontaminate items such as wheelchairs, portable equipment, and waiting room chairs. The authors cite a reference1 supporting the fact that “thoroughness of manual cleaning is often inadequate, and application can be challenging and time-consuming particularly when surfaces are irregular or large open areas are being cleaned.” They found that applying a dilute sodium hypochlorite bleach solution with an electrostatic sprayer “could provide rapid and effective decontamination of portable equipment and large open areas.”
Electrostatic Sprayers and Coronavirus
EPA maintains a list of disinfectant products approved for use against the COVID-19 virus. “List N,” as it is known, includes new application methods, including electrostatic sprayers, for approved disinfectants. EPA announced recently it has developed an expedited review process to add electrostatic spray application directions for use on disinfectant labels. Manufacturers of approved products or new products may take advantage of this accelerated review process.
An Ingenious Use of Chemistry
