Safety of Ozone
How to safely use an ozone generator?
The basic requirements for the safe use of an ozone generator are as follows:
- Use in the environment with no people, pets, sensitive plants or items (such as rubber products, plastic products, fabrics, paintings, etc.).
- To avoid inhaling a high concentration of ozone, it is recommended to choose ozone generators with automatic shutdown function.
- To ensure an adequate diffusion of ozone, it is recommended to keep the treated space ventilated for at least 30 minutes after an ozone treatment.
Is ozone safe for food sterilization?
Yes, it is safe to use ozone for the sterilization of food. Ozone received a GRAS (Generally Regarded as Safe) approval from the U.S. FDA in 2001 and later a GRAS approval from USDA in 2002.
Can I use an ozone generator in my car?
Yes. But compared to use it in other spaces, its working time in the car should be controlled. A good tip is to limit the application time to 20 minutes or less. In addition, in order to avoid the impact of ozone on the rubber and leather materials in the car, instead of using ozone gas, it is suggested to use ozone water to wipe the interior of the car for a sterilization or odor removal purpose.
What materials can be affected by ozone?
Whether ozone gas will affect a material is determined by the nature of the material itself, but also by ozone concentration, air humidity and whether the material has been treated against ozone and other factors. The following are indicators of the effects of ozone on different materials:
A = Excellent – Ozone has no effect on the material.
B = Good – Ozone has little effect on the material. Can be used at low ozone concentrations or for short periods. However, long time or high concentration of ozone may still cause erosion of the materials.
C = Fair – Ozone has a moderate effect on the material. These materials should only be used in low-level ozone environments or for short-term applications. Prolonged use will cause erosion of the material.
D = Poor – Ozone can have a serious effect on materials. The material will decompose in a short time (a few hours to a few days).
A – Excellent:
Galvanized Steel in Air
Stainless steel – 316
B – Good:
Aluminum in Dry Air
Stainless steel – 304
C – Fair:
Galvanized Steel in Water
Does ozone have any medical uses?
There is. However, most medical applications are not approved by the FDA. So, we do not recommend them until there is more research to prove it. On the other hand, ozone can be personally used for health care. For instance, you can use ozone water to wash face or have an ozone bath. There is also ozone olive oil.
EPA warns that ozone generators are unsafe for people. Is it right?
Yes, this is a question that end customers often ask while purchasers rarely care about. It is certainly not safe to breathe a high concentration of ozone. Therefore, except for very low ozone yield models that meet EPA guidelines, we recommend using ozone in environments where there are no person, animals or plants. In addition, it is recommended to allow at least 30 minutes for ozone diffusion before re-entering the room. Therefore, it is a good time for an ozone treatment while you are out. An ozone generator will not pose any health risks as long as it is used following the user manual.
