Sterylis VS Manual
| 7
The device is designed to sterilise rooms by generating ozone in a concentration that may pose a threat to the health and
life of humans and other living organisms. Despite the safety principles during the operation of the product as described in
the following chapters, it is essential to read the information below on possible effects of ozone and on first aid in case of
exposure to a hazardous concentration of the substance.
Ozone, due to its strong oxidizing effect, has an irritating effect on conjunctivitis and respiratory mucosa. This may result
in burning pains and redness of conjunctivitis, coughing, wheezing, difficulty in breathing, increased frequency and severity
of asthma attacks in people suffering from this disease, and increased ailments in people with coexisting respiratory and
cardiovascular diseases. In very high concentrations it is dangerous to live.
The effect of ozone on living organisms depending on concentration is shown in the table below (based on [6]):
Effect
Concentration
Permissible workplace ozone concentration at 8 h exposure
0.05-0.1 ppm
Odour perceptibility – average
0.02 ppm
Odour perceptibility – depending on body properties
0.01-0.04 ppm
Minimum concentration causing irritation to eyes, nose, throat, headache, shortness of
breath
from 0.1 ppm
Respiratory disorders, reduced oxygen absorption, respiratory disorders, general fatigue
and chest pain, dry cough
0.5-1.00 ppm
Headache, breathing difficulties, drowsiness, severe pneumonia at prolonged exposure,
skin irritation or dryness
1-10 ppm
Danger to life and health
10 ppm
Fatal concentration for small animals in 2 hours
15-20 ppm
Fatal concentration in a few minutes
above 1700 ppm
