Identification of the Substance

Product identifier

Trade name: Ozone

Use of the Substance/Mixture

Specific use(s): Oxidant


Gaseous ozone produced by an ozone generator on site, either for air or water, can be use for abatement of odors, organic compound oxidation or antimicrobial intervention. It is also useful in food processing, groundwater remediation, and various other applications.

Symptoms and Effects

Symptoms: You might experience headaches, coughs, dry throats, tightness in your chest, and shortness of breath

Risk: A constant exposure to very high levels (> 10 ppm) can result in lung congestion. If the exposure is lowered, this effect diminishes. A very high dose (> 20 ppm) can prove fatal.

Fire Fighting Measures

Ozone itself is not flammable, but it is a strong oxidant and may cause combustion, and even explosions, if it is handled inappropriately. Use extinguishing agents that are appropriate for the type of material being burned.

Accidental Release Measures

Exit the area while the ozone levels subside. Turn off the ozone generator as a safety precaution, ventilate the area, and remove the pollutants.

Storage and Handling

From the point of generation to the point of application, ozone must be contained within ozone-resistant tubing and pipes. Any leaks must be fixed before the ozone can be applied.

Exposure Control Standards

Exposure limit according to OSHA: 8 hour Time Weighted Average 0.1 ppm

Whenever you enter an area with high levels of ozone, wear a fully contained self-contained breathing apparatus.

Using an ozone destruction unit (thermal or catalytic) to off-gas ozone is an adequate solution for engineering controls.

Stability and Reactivity

During normal ambient temperatures, ozone will spontaneously react and decompose. It is highly reactive and unstable.

You should avoid contact with alkenes, Xenon tetroxide, hydrogen bromide, nitrogen trichloride, tetraluorohydrazine, and other aromatic compounds like rubber, bromine diethyl ether, dicyanogen, bromine diethyl ether, dinogen tetroxide.

Ecological Information

Ozone release may adversely impact the immediate surrounding area, including plant and aquatic life. Discharging ozone in water would also have detrimental effects.  

Disposal Considerations

To release ozone into the atmosphere, it should be dispersed through an ozone destruction device that uses heat and/or a catalyst to break the ozone into oxygen.

Transport Information

The ozone must be produced at the location and at the time of use, since it is unstable, reacts with other substances in the environment, or decomposes when exposed to natural sunlight.
