UV-B radiation at 280nm (peak UV-C 254nm) causes the destruction of ozone (O₃), breaking it down into diatomic oxygen (O₂) and atomic oxygen (O). Only when you apply UV-C 240nm or below (peak185) will you have enough energy to break the bond of diatomic oxygen (O₂) in turn creating enough atomic oxygen (O) to form any substantial amount of ozone (O₃).
At ground level, atomic oxygen (single oxygen atoms) has a very short lifespan. This is because it's highly reactive and quickly combines with other molecules to form stable diatomic oxygen (O2) or other compounds. While the exact timeframe varies depending on the specific circumstances, its lifespan is typically measured in nanoseconds or picoseconds. Without the presence of 240nm all you get is lots of O₂.
Low current electrolysis/photolysis of water (Ozone generator) will create (O₃), but in the presence of 280nm, photodissociation occurs and (O₃) is broken down to both a stable bond (O₂) and (O) With a picosecond lifespan. The simple solution would be an air quality reader if there were any fear. The real danger comes from increasing the level of (O₂) or a lack of proper ventilation while doing so, In the air we breathe, it's around 21% Oxygen. Once the saturation level gets to 23.5%, things get combustible. Certainly wouldn't want that to happen.
This is why I caution people to avoid using "ozone generators" disguised as air purifiers to clean their air. Especially not in conjunction with UV lights in a grow, oxygen overload.
Stay safe, everyone. Don't mess with UVC, or eat Tide pods, both are no no no.
