Bio Fogging with Disinfectant for Quick Sanitisation

By now, the words “sanitisation” and “antibacterial” should feel familiar. For big, frequently used indoor spaces, such as offices, hotel rooms, and industrial environments; bio fogging is a great solution to effectively freshening up a space while prioritizing health and safety.

In this article, you will find out what bio fogging is and how to use it to your advantage.

What is bio fogging?

Bio fogging is an efficient process in which sanitation chemicals are delivered through fogging, for the purpose of sanitising a large indoor space. This is an efficient way of sanitising out-of-reach surfaces, or areas that are often missed during a normal cleaning. That is because the chemical mist that is sprayed in the room settles on all surfaces that are exposed.

Bio fogging is a great way of deep cleaning industrial environments. However, it should be done during periods of time where the room is closed. Nobody should go into the room for at least 2hours, and should be thoroughly ventilated before using it again.

The decontamination can last up to 30 days, and can be done monthly if needed.

How does fogging work?

Biocide particles are dispersed into the room and they hang around for enough time to eradicate any airborne viruses or bacteria. All the cleaning products and elements used in the process should not be harmful to the environment or the surfaces that need to be disinfected.

There are hand-held machines that turn antimicrobial solutions into vapour, which is then dispersed with a fan for the biocide particles to reach all corners of the room. This fog-like mist that is efficient in covering all exposed surfaces.

Usually, fogging is done through a two-stage process:

  • Stage one

First, all visible dirt should be cleaned on all of the surfaces, including dust and debris. If this isn’t done before fogging, the mist will land on the debris and there could be a risk of the disinfectants being deactivated by organic matter.

  • Stage two

For the purpose of ensuring bio fogging is performed safely and risk-free: All personnel should leave the room before the actual fogging begins. Smoke alarms or any sensors that are exposed should be covered. Fans or air conditioning units, as well as all electrical equipment should be turned off. Doors and windows should be closed.

After at least 2 hours have passed, ventilating the room through opening of windows is necessary before allowing people in again.

How much does bio cost?

Prices can range from £280 to over £1500 on average. Bio fogging prices vary greatly according to the room size, and the amount of time that you want the fog to action in the room.

For example, a 500 m³ room and 3 hours of fogging (including the preparative cleaning), can cost around £280. On the other hand, a space that has 4000 m³, with around 12 hours for the procedure, the price you can expect would be around £1,380.

Through use of specialist equipment, operated by trained and qualified professionals who work under safety regulations; the cost of bio fogging is a small one to pay under a climate where health is in critical priority.
