Ozone Machines

Q: Are you aware of any regulation that would disallow the use of Ozone machines in hospitals? Are ozone machines allowed in hospitals? We had thought about using ozone machines in lieu of air fresheners due to employee complaints about the ‘odor’ of the air fresheners affecting respiratory system of asthma suffers.

A: This is not such a good idea. Ozone has its own OSHA Permissible Exposure Limit (PEL).  Ozone is a gas that can cause health problems, including respiratory tract irritation, breathing difficulty, asthma exacerbation, and chest pain. Ozone is not an effective way to clean the air and when used at the acceptable PEL, ozone does not remove dust or pollen and does not kill bacteria or mold.

Google ‘ozone’ on the internet and you will find plenty of documents supporting this information. Based on the literature, I do not see how you could complete a credible risk assessment that would allow ozone machines in hospitals.
