Sanitizing with Ozone
The good news is that ozone has successfully kills all types of pathogens (virus and bacteria) including SARS, a nasty coronavirus of a few years ago. We now have a medical study that confirms that ozone past coronaviruses, leading to the unproven belief that ozone will also kill new version of the coronavirus. Viruses and bacteria cannot become immune to ozone. The science of ozone is clear that all pathogens cannot survive a proper ozone treatment.
This is important news for anyone with an ozone generator, and motivation to buy a professional ozone generator with a built-in timer. Always use a timer on an ozone generator to prevent over-treatment. We know that a one-hour treatment at 4-5 ppm is sufficient to kill all types of pathogens including Ebola, MRSA, SARS, and coronaviruses. Good studies show that 30-60 minutes at 4-5 ppm ozone saturation will kill off nearly all kinds of bacteria and viruses.
Elevated levels of ozone are only applied in vacant buildings/areas because ozone is a respiratory irritant. However, the ozone reverts to typical O2 in about 30 minutes. Or, just let in fresh air for a few minutes to allow normal activity to resume. Repeat the treatment as desired, and follow the other known disease prevention steps.
For those who are called on to clean and sanitize buildings, we suggest the GCI course, "Infection Control for Cleaning Service Workers" found on the NOAI.org homepage.
You see, ozone is a form of oxygen (O3 instead of O2). The third oxygen atom breaks off during the ozone treatment and attaches to any organic threat. The results is ozone burns a microscopic hole in the outer membrane of the bacteria or virus. But, this now happens millions of times causing the pathogen to quickly die. Oxidation is simple science, and ozone is a higher level of oxygen ... and oxidation.
While there are products that use "The Power of Oxygen" to whiten clothes, clean your teeth, or kill germs; ozone is a gas found in nature. Every day the UV light from the sun creates ozone in our atmosphere. But, it happens at a very low level and spreads everywhere. Using an ozone generator raises the saturation level of ozone in a room or building. This creates a higher level of oxidizing power that can be applied in short cycles to any vacated area.
Since ozone is just another form of oxygen, we are using nature's solution by increasing the ozone levels. To illustrate ozone with water, imagine cleaning a building with a cup of water. You can only do so much with a cup of water. But, what if we had 100 gallons of water to clean the building. Well, we don't want a flood, but we have all the resources we need to clean everything. If we make the ordinary water better by adding soap, the cleaning improves even more.
Viruses and bacteria cannot become immune to ozone. Why? Because all living things need oxygen. The sun creates ozone outside when it shines through an oxygen atmosphere. But, the is outside with little impact inside. An ozone generator takes the outside process to the inside of a building. We quickly raise the ozone level in the building for a short period of one to two hours. Then, we air the building for a bit.
Instead of hours and hours of intense scrubbing and gallons of chemicals, ozone touches all surfaces and does its amazing work. And, ozone can be applied nightly for 30-60 minutes when workers are away for a constant sanitizing process that can last as long as the infectious threat.
Three additional facts. Maintain your normal cleaning cycle and clean high-touch areas hourly. Practice good hygiene and infection prevention. Finally, high-saturation ozone treatments require humans and pets to vacate the building. High ozone levels are a respiratory irritant. The ozone reverts back to oxygen in about thirty minutes or even quicker when fresh air is introduced.
Lastly, ozone has a smell like a chlorine pool area. This will pass, but is not harmful after the air is refreshed. After all, bleach leaves a distinctive smell afterwards too. But, instead of a chemical product that may have unintended IAQ issues, ozone is harmless after the refresh cycle.
