CERN has been advised by the manufacturer of the defibrillators installed on site that some of the devices' electrodes may be defective. As a result, some defibrillators may not be fully efficient but their use is not dangerous and still recommended in case of cardiac arrest.
The CERN Fire and Rescue Service has ordered new electrodes to replace deficient ones if necessary.
Stickers have also been put on the defibrillators reminding users to call 744 44 prior to using the device and to follow instructions received from the Safety Control Room operator.
