Bio-fogging FAQ’s

Corona Virus Sanitation

What is the difference between fogging and electrostatic spraying?
Fogging is atomising a chemical to apply it as a mist. electrostatic spraying is a method of applying an electric charge to a liquid in order to get it to cling to a surface. Both methods are equally effective if the correct machines are used and the appropriate biocides are correctly applied.

Are all disinfectants used in bio-fogging the same?
Not all sanitation or sterilisation agents are the same, some are water based, some are alcohol based, some contain bleach while others contain chlorine’s, peroxides or other chemicals. Our choice of biocides for your treatment will depend on the assessment we carry out prior to sanitising your premises.

Is bio-fogging safe to use in food areas?
Only a few of the fogging solutions available are certified as safe for use in food preparation areas. We use non bleach formula’s for indoor treatments which are certified as safe to use in food preparation areas.

Can bio-fogging be used on computers?
We do not recommend the use of bio-fogging on or near any electrical equipment. Fogging solutions work by producing small particles of liquid which settle on the surface, if too much moisture is released onto electrical equipment it can cause the components to short out. At Bionise we cover all electrical equipment prior to starting the treatment and recommend the use of isopropyl alcohol wipes to clean computer screens and keyboards.

What is an enveloped virus?
In layman’s terms, an enveloped virus is one that is protected by an outer layer, if you remove or damage that layer then the virus cannot attach itself to anything. Our biocides work by basically puncturing the layer rendering the virus ineffective.

How long does it take to sanitise a room?
The time it takes to decontaminate and sanitise your premises will depend on the size of the rooms to be treated, we use high velocity fogging machines designed specifically for bio-fogging procedures, so small rooms and offices take an average of five to ten minutes whereas larger rooms (1000m²) can take up to 90 minutes.

How much disinfectant do you need? 
It varies according to the flow rate and method of application, but as a rough guide, we use 10ml per square metre of floor area, so a 5 litre container would cover approx. 500 sq metres.

Is UVC treatment effective?
Although “Ultraviolet C” (UVC) irradiation is highly germicidal, the use of UVC for the prevention and treatment of large areas is time consuming and is not guaranteed to reach all areas of the room being treated. At Bionise we only use UVC to treat those areas and components that cannot be treated using conventional methods. Our UVC treatment is mainly used on electrical components that could suffer damage if treated with a fogging solution.
