I Smell Ozone …Is It Dangerous?
Just smelling ozone is usually not an issue if it is on a short-term basis.
When using a medical ozone generator, often a small amount of ozone will be released as hoses are changed, syringes are purged or water is being ozonated.
Potential Health Effects as listed on the Ozone Safety Data Sheet (SDS):
|Ozone Affecting Health (observed effects)||Concentration (ppm)|
|Threshold of odor, normal person||0.005-0.02|
|Maximum 8 hr. average exposure limit||0.1|
|Minor eye, nose, and throat irritation, headache, shortness of breath||>0.1|
|Breathing disorders, reduced oxygen consumption, lung irritation, severe fatigue, chest pain, dry cough||0.5-1.0|
|Headache, respiratory irritation, and possible coma. Possibility of severe pneumonia at higher levels of exposure||1-10|
|Immediately dangerous to life and health||10|
|Lethal to small animals within two hours||15-20|
It is prolonged exposure that may cause lung irritation, however, coughing usually occurs long before there is any damage to the lungs.
Breathing ozone can trigger a variety of health problems including chest pain, coughing, throat irritation, and congestion. It can worsen bronchitis, emphysema and asthma.
Ozone can be bubbled through olive oil and inhaled safely but not as straight ozone gas.
