Abstract: A novel bomb spray for use in disinfecting a room is disclosed where the bomb spray includes a reservoir and a spray nozzle where the contents of the reservoir include a disinfectant chemistry that is dischargeable through the spray nozzle. The spray nozzle is optimized to discharge all of the contents of the reservoir and to project the disinfectant chemistry simultaneously in a vertical and radial pattern in order to broadcast the disinfectant spray on all of the surfaces in the room. The disinfectant chemistry is selected from formulations that contain some amount of a quaternary ammonium compound for imparting bactericidal properties. In addition, the disinfectant chemistry includes a volatile matrix that promotes rapid drying of the disinfectant after it has been dispersed into the room.
