What is UV-C Light?

UV-C is the germicidal wavelength released by the sun, with wavelengths between 200-280 nanometres. Wavelengths within this range have been used to help fight bacteria and viruses for over 100 years.  

With scientific research done in the early 1900s scientists developed ways to use the light within the UV-C wavelength to help fight tuberculosis. Within a few years it was used to disinfect drinking water. Years later hospitals integrated overhead systems to disinfect surfaces and to purify the air.  

How UV-C light works

When the UV-C light is shined on bacteria, viruses, and other pathogens, it deactivates their DNA as well as destroying their ability to multiply and ultimately killing them.

The Effectiveness of UV-C disinfection can vary based on a few factors, including the length of exposure to bacteria, intensity of the radiation and a microorganism’s resistance to the radiation that is delivered by the light. Length of exposure is based on the size of the area or surface that you wish to disinfect. Larger areas require more radiation and longer exposure times to ensure all objects and surfaces are hit with the light.  

The best method to face some of these variables is delivering multiple passes of light exposure. Exposing the subject, you would like to sanitize multiple times will ensure that the bacteria with a bit more resistance will also have their DNA deactivated.  

It is critical to ensure the object or surface that requires disinfecting is exposed to direct light from the UV-C fixture or bulb in order to disinfect properly.  Anything blocking the light, including shadows will lessen the intensity of the light.  

UC-V light should always be handled with care. prolonged direct exposure can be harmful to skin and eyes. Wearing proper protective eye wear and clothing that does not expose any skin is highly recommended to ensure the safety of the operator.

What is fogging?

Why use fogging? Key benefits

  • Disinfecting with a fogger kills 99.99% of viruses, bacteria, mold, and mildew. 
  • Small particles reach areas that may not be cleaned with traditional techniques 
  • Environmentally friendly  
  • Highly cost effect
  • Non-corrosive
  • Little to no waste implications
  • Effective and long lasting
  • Requires little effort from user 

What is fogging?

Fogging is an efficient way to disinfect both indoor and outdoor objects, surfaces, and areas to eliminate the growth of harmful bacteria, mold, and viruses.  

Foggers create a small particle, between 0-50 microns, whereas traditional sprayers have a particle size of around 250 microns. When you fog, you are creating an environmental fog that is forming a canopy that moves through the air and slowly descends to below surfacesBecause the particles are so small, many of them are picked up by the airflow in a room, allowing the particles to travel further, ultimately carrying the disinfect solution to hard to reach areas. Particles not only disinfect the surface it touches or lands on but also disinfectthe air within the spray area. 

Known industries disinfecting with for applications

  • Office spaces, including kitchens boardrooms and restrooms  
  • Care centers and hospitals  
  • Car dealerships and car share vehicles  
  • gyms  
  • warehouses 
  • educational buildings 
  • airports and airplanes 
  • hotels and nightclubs  

Safety

Safety when fogging is dependant on the solution that is added to disinfect with. Fusion UV-Clean has tested both water-based ammonium chloride and water-based sodium chloride and both have been proven safe to spray without the use of any personal protective equipment. 

The fogging machines are safe to use in both indoor and outdoor environments. No PPE is required when using but some operators may request ear protection because many of the machines are loud when turned on.  

 

Fogging should be used in conjunction with touch-point cleaning. Doing this will ensure that parts of your workspace which are commonly touched or used are both cleaned and disinfected.
