Warning
This CO control unit is designed to protect people from the acute effects of carbon monoxide. It cannot
prevent the chronic effects of carbon monoxide exposure. The CO control unit can not fully protect people at
special risk, such as those with particular medical conditions. In cases of doubt, consult a doctor.
The table below sets out the symptoms, the corresponding CO concentrations and lengths of time that a person needs
to be exposed to this concentration until symptoms occur.
