11) Will the temperature or humidity of the air or water affect ozone?
The temperature and humidity of the air will directly impact on the concentration of ozone gas
produced. The more humid and the hotter the air, the less concentrated the ozone produced
will be. Likewise the temperature of the water has a similar effect; the cooler the water the
ozone is injected into, the more effective the ozone will be at removing contaminants! Heated
pools require 10-15% more ozone than traditional pools.
12) Is ozone safe?
Ozone has been documented for over a century now, so quite a lot is known about it. OSHA -
Occupational Safety and Health Agency has stipulated that the safe allowable level of residual
ozone is 0.08 ppm. This is supposedly based upon the historical safety of ozone. Note that this
permissible level is for continuous exposure throughout an entire 8 hour day for 5 days a week.
No Federal or State agency can agree on what the maximum level of ozone exposure should be,
so there is no standardization in maximum permissible ozone levels. That signifies these
numbers are arbitrary, meaning they are not really sure of what a maximum sustainable ozone
level should be. Since excess ozone gives off an unmistakable strong "bleach like" odor, one
always know if too much is present in the air. In other words before ozone could possibly have
any unsafe effects, a person would be greatly offended by its bleach like odor. Ozone is safe to
use in occupied areas because we notice its unpleasant odor at very low levels and then have
the ability to turn it down. Ozone generators, when used correctly will not exceed government
guidelines for continuous safe exposure. Precautions should be taken, however, because the
nose can lose its ability to sense the ozone after a sustained period of time. If one senses a
headache or sore throat it may mean the ozone level is too high. The fact remains if the ozone
level is much higher than is recommended to be considered safe, it would become so pungent
that anyone could sense it. Ozone does this by becoming so offensive at high levels that we
would not be able to stay in the environment for more than a very short period. This is much
like what would happen if we entered a smoke filled room. No one has ever claimed a worker's
related illness resulting from ozone exposure
13) Is ozone safe for my pool equipment?
Most pool systems these days come supplied with plumbing that is ozone-resistant, example
PVC piping. However, Ozone gas can corrode metal and other materials such as nylon and
rubber. Care must be taken to check that all plumbing and piping between the injection point
(Venturi Injector) and the point of entry to the pool are made of ozone-resistant materials. All
our ozone generators are supplied with ozone-resistant accessories
14) Is ozone safe for swimmers?
Ozone dissolved in the water is pH neutral so the pH will not harm equipment or people. The
amount of ozone added to the water is enough to kill bacteria, virus, cysts, mold and spores, but
is safe and non-toxic to humans and pets - no red, irritated eyes and dry, itchy skin. When
properly installed and plumbed all of the ozone generated will be dissolved in the water or used
up oxidizing impurities in your water.
