Is Ozone Safe? September 18 2017, 0 Comments

Have you ever experienced the fresh smell that is created after a lightning storm? If you answered yes, that means you’ve smelled the pure aroma of ozone. With oxidizing power 3,000 times more effective than bleach, ozone is the second most powerful oxidant in existence (deadly fluorine gas is first). Ozone is proven to be one of the most effective and methods to safely remove bacterial, viral, and fungal activity. Ozone has many positive benefits, however some may not know how to utilize an ozone generator in the safest way.

What is Ozone?

When used correctly, ozone is a safe and effective sanitizer for air, water and oil applications. Ozone, also referred to as active oxygen, is simply another form of oxygen. Three oxygen atoms make up ozone (O3) instead of two atoms that form oxygen (O2). The amazing qualities of ozone have been occurring naturally since the beginning of time.

Ozone is created when ultraviolet rays emanate from the sun, split the oxygen molecules and form an unstable oxygen molecule (O2) and a highly unstable oxygen atom (O1). The molecule being oxidized then bonds with the loose (O1) atom, creating an oxide of the substance thus (O3).  Another manner in which ozone is formed is through the high energy contained within electrical discharges, which occur during lightning storms.

In addition to occurring naturally, ozone can also be reproduced scientifically in safe, controlled quantities. This is not a new technology; rather a thoroughly tested, safe and highly-utilized reproduction of nature’s gift to us. The first recorded publication on the value and benefits of ozone was published in an 1885 Florida Medical Association paper entitled "Ozone" by Charles J. Kenworthy, M. D., M.R.S.V. This shows that ozone was used in the medical & scientific fields in the U.S. before 1885. A2Z Ozone utilizes cold corona discharge to safely produce ozone. This is a common method that most ozone generators utilize today because it can create ozone at many different concentrations needed for a wide array of applications.

How to Use Ozone Safely

Ozone generators can be used in unoccupied areas—just remember the three P’s: no People, Pets, or Plants. A2Z Ozone’s in-home generators are designed to produce just the right amount of ozone to effectively sanitize your water and air, but not strong enough to exceed recommended EPA levels. The current EPA standard for in-air ozone is .05 ppm. If inhaled in large amounts, ozone can become detrimental to health so it is important to run units only in unoccupied areas and be sure to remove valuables before starting the unit.

Many of our units feature timers that will shut the unit off after it runs for the selected amount of time. This allows users to turn the unit on and set the timer before exiting the room. Return after the unit has had enough time to run the setting and had 30 minutes to 1 hour to allow the ozone to dissipate, reverting back to oxygen. Keep in mind, as rooms increase in size, fan speed and ozone timer should increase also.

OHSA has safety guidelines regarding ozone exposure are:

  • 2 ppm for no more than 2 hours exposure
  • ppm for 8 hours per day exposure doing light work
  • 08 ppm for 8 hours per day exposure doing moderate work
  • 05 ppm for 8 hours per day exposure doing heavy work

Ozone has a 20-30 minute half-life in the air meaning that its concentration will break down quickly. After running a unit, be sure to wait out the half-life before returning to the room to allow the ozone to dissipate. If the smell of ozone is still strong after waiting 30 minutes, open windows to air out the room.
