question: What information is available about the use of electrostatic sprayers or foggers for the disinfection of rooms and surfaces in healthcare environments?
answer: These devices are typically used as an adjunct technology to terminal room cleaning. This means that the patient has been transferred or discharged and is no longer occupying the space.  So that EVS may begin cleaning and disinfecting the room in preparation for a new patient (e.g., terminal cleaning). For information about the application of EPA List N disinfectants with electrostatic sprayers and foggers, refer to the EPA’s Frequent Questions about Disinfectants and Coronavirus (COVID-19). If a product does not have an electrostatic spraying or fogging use on a label, the EPA has not evaluated the safety and efficacy of using that product with an electrostatic sprayer or a fogger. Foggers can be hand-held or no-touch devices (NTDs). When using an electrostatic sprayer or a fogger to apply disinfectants, always follow manufacturer directions for operation and maintenance of the sprayer or fogger and the disinfectant label’s use directions (e.g., application rate, distance to surface while applying, and contact time). Follow the disinfectant’s label recommendations for appropriate personal protective equipment (PPE) for the operator, and adhere to any recommended re-entry times for bystanders, other staff members, or patients.
