Friedrichshafen (dpa / lsw) – In order to test the emergency supply, the Friedrichshafen Clinic will turn off the electricity for an hour in the next few days. The so-called black test should show possible gaps in the power supply from the emergency generator and prepare employees for emergencies, said a spokeswoman for the Klinikverbund Medizin-Campus Bodensee, which also includes the Tettnang clinic. Medical-technical devices and other vital supply lines would have to function uninterruptedly and flawlessly for the safety of the patients. The emergency power supply is tested at regular intervals. The “Schwäbische Zeitung” (Friday) had previously reported on it.
