A dental engineer was sent to investigate N2O problems at a dental surgery in Dover, Kent after complaints from staff about the effects of the gas.
Previous passive monitoring in the surgery had indicated a time weighted average (TWA) of N2O at 90ppm, and a suspected leak in a faulty machine was sent for service and repair in order to fix the problem. However, staff continued to notice the effects of N2O.
Using a G200 N2O monitor supplied by Bedfont Scientific, the engineer was able to identify a leak from faulty sedation equipment, as well as use a further two G200's for staff to monitor their TWA.
