Ozone can be used to sterilise equipment and to significantly reduce or eliminate the spread of micro-organisms in hospitals. High levels of Ozone are required so people are not present. An ozone monitor with data-logging is a useful tool during treatment to document that the concentration has reached optimal levels for the appropriate time and then to check that it is safe for people to re-enter the room. Measurement can help optimise the effective dose and documentation of each room sterilisation can support liability issues or complaints.
The area to be purified is evacuated (including animals and people), the equipment is deployed and ozone concentrations are brought up to very high levels and maintained there for several hours, depending on the problem to be cured. When purification is complete, powerful fans are brought in to evacuate all the ozonated air and oxidized chemicals, the area is tested to ensure a safe ozone level (typically less than 0.05ppm).
An ozone monitor is required to log inside the room to document the concentration reached the appropriate level for the required time while the room is not occupied and also to check that the o3 levels are well below OSHA health & safety levels before people can re-occupy the room. Measurement can help optimise the concentration vs time required to be an effective room sanitizer and documentation can support defence of customer complaints or liability issues.
