Fogging with Liquid Chlorine Dioxide

If your facility does not necessarily require a 6-log (99.9999%) sterilization level decontamination, ClorDiSys offers alternative options to our chlorine dioxide gas services including chlorine dioxide fogging. The term fogging is the method of decontamination when a liquid is applied in a mist onto a room’s surfaces. Compared to gaseous chlorine dioxide, which spreads throughout an entire facility and penetrates into the smallest cracks, fogging has some limitations.  Liquid fogging has many factors that reduce the ability of this agent to reach all the required areas for the required amount of time in order to achieve a successful decontamination cycle.  Liquids have difficulty penetrating into crevices as they cannot overcome the surface tension.   

When providing disinfection fogging services, ClorDiSys sprays surfaces with liquid chlorine dioxide applied at concentrations capable of eliminating viruses, bacteria, fungi and spores. Handheld foggers are used such that a trained technician is able to reach more surfaces than a stationary fogger by opening drawers, cabinets and enclosures, as well as changing the angle of application in order to minimize shadow areas which are not being contacted. During application, PPE such as a full-face respirator or PAPR is required for all people in the room. Safe concentrations should be verified prior to re-entry without PPE. In most cases, only minutes are required to get below 0.1 ppm prior to re-entry.

Fogging with a liquid chlorine dioxide provides a more economical disinfection method compared to gaseous decontamination, offering a value proposition for less critical contamination control applications.  Interested in learning more about fogging with liquid chlorine dioxide?
