Ozone and humans
Ozone is a toxic gas, after inhalation it can cause sickness if inhaled in sufficient quantity.
* 0,06 PPM for 8 hours a day, 5 days a week (PPM = Parts Per Million)
The following diagram gives information about exposure times at different concentration and their influences on humans.
All ozone generators should be equiped with ozone monitors and a safety system which shuts down the generator at 0,3 PPM. Best is also to set up an alarm at 0,1 PPM so people can take action in time.
