Is it possible to get an electric shock when working with a high frequency unit?
There is absolutely no risk of getting an electric shock. However, a burn is possible if you touch an unprotected metal instrument with an active electrode while in physical contact with the patient. High frequency waves take the way of lowest resistance, and in this case the conduction of waves occurs through the metal instrument and your body. Such cases, however, are extremely rare and none came to our attention during the last years.
