Follow the government guidelines. Contain the spread of the virus. Save livelihoods.

Fogging or Misting treatments may be a suitable option to help control the spread of coronavirus and disinfecting a larger space or room. Any use of these treatments for these purposes should form part of your COVID-19 risk assessment. Users must be competent and properly trained.


If you choose to use fogging or misting treatments as a way of disinfecting surfaces, discuss your requirements with us to help you decide if a product/system meets your needs. The treatment you use will depend on:


  • the size of the area to be treated, its shape and how easily it can be sealed off while delivering an airborne product

  • whether there are hard or soft surfaces - soft furnishings may act as a 'sink' for the airborne chemicals and emit them for a period of time after treatment (remove items such as sofas before treatment)


Disinfectants applied as a fog or a mist may reach harmful levels during delivery and may cause eye/skin damage if people enter an area undergoing treatment. People should not enter rooms being treated by disinfectants applied as fog or mist.


Locking rooms during the treatment will help to contain the emissions but other measures such as taping of doorway gaps or plastic screening off of some areas of the room may also be required.  Good ventilation will also help clear the disinfectant after the treatment if this can be controlled from outside of the room. 


Fogging or Misting method


If using fogging or misting, you should ensure the correct concentration of the active chemical is used to achieve disinfection. However, be careful not to apply too much so that it leaves a wet surface or residue, which may present a hazard to anyone entering the room after the treatment is completed.


Disinfectants dispersed by fog or mist may not result in even application to all surfaces. Hidden or 'shadowed' surfaces, or the surface underneath objects, may not be disinfected. The use of these methods in rooms of complex design with multiple surfaces may not be suitable.
