RISKS CONNECTED WITH USE OF THE MACHINE

Description

Residual risks of the ozone generator

Human tolerance to ozone

Ozone is a toxic gas, after inhalation it can cause diseases if

inhaled in sufficient quantities.

Humans can endure limited ozone exposure, symptoms such

as dry mouth and throat, cough, headache and chest

constriction and close to lethal limits, when the concentration

of ozone increases, serious problems will follow.

Limits * 0.06 ppm for 8 hours a day, 5 days a week (ppm =

parts per million) * 0.3 ppm for up to 15 minutes. These limits

are a maximum acceptable concentration (CMA), these

concentrations are much higher than the olfactory level at

which ozone can be smelled.

The following diagram provides information on times of

exposure to different concentrations and their influences on

humans.

Ozone toxicology

In higher concentrations, ozone can cause health effects after inhalation.

Symptoms such as mucosal irritations and headaches often follow.

These symptoms can also occur during photochemical smog episodes.

Higher concentrations (> 50 ppm) and long-term exposure (> 30 min) can be fatal. However, staying in a

room with this type of concentration is almost impossible.

The long-term effects of ozone exposure are not fully known, but a reduction in lung capacity and an increase

in lung disease should be considered.

To prevent the above health risks, a maximum amount of ozone has been established for the areas where

ozone is used.

This is the so-called maximum permissible concentration, or CMA value. This value describes the maximum

concentration of a substance to which a human can be exposed for a certain period of time.

For a normal five-day, eight-hours-a-day work week, ozone has a CMA value of 0.06 ppm (parts per million

or mg / L). For 15 minutes, the CMA value is 0.3 ppm.

Ozone can be measured in ppm or ppb (parts per billion or μg / L), according to various principles.

With these measurements, you can monitor the ozone concentration in a system.

When the CMA values are reached near the ozone generator, an alarm is issued.

Ozone has a very characteristic odor, which quickly reveals the violation of the CMA value. The level

at which ozone can be smelled is around 0.02 ppm.

Ozone decomposition

When ozone is produced it decays quickly because it is an unstable compound with a relatively short halving

time.

The halving time of ozone in water is much shorter than in air (see table 1). Ozone decays in drinkable water

(pH: 6-8.5), partially in reactive OH radicals.

Hence, the evaluation of an ozone-based process always involves the reaction of two species: ozone and

OH radicals.

When these OH radicals are dominant particles in the solution, it is called the advanced oxidation process

(POA).

Halving of ozone in OH radicals in natural waters is characterized by an initial rapid decrease of ozone,

followed by a second phase in which ozone decreases by first order kinetics.

SO-20

Rev 00.00

Pag. 12 di 16

Depending on the quality of the water, the halving time of ozone ranges from seconds to hours.

Factors that influence the decomposition of ozone in water are temperature, pH, environment and

concentration of dissolved material and UV light.

The main factors influencing ozone decomposition are discussed below.

Influencing factors:

Temperature: it has an important influence on the halving time of ozone. Table 1

shows the halving time of ozone in air and water. In water the halving time of ozone

is much shorter than in air, in other words ozone decomposes faster in water.

Ozone solubility decreases at higher temperatures and is less stable. On the other

hand, the reaction rate increases with a factor of 2 or 3 every 10°C [5,6]. Mainly the

ozone dissolved in water cannot be applied at a temperature above 40° C, because

at this temperature the halving time of the ozone is very short.
