The demagnetizing coil presents a lethal hazard for persons with active electronic implants (e.g. heart pacemakers). - AS82.85-Z-0001-01A

Persons with such electronic implants should not work with the demagnetizing coil or remain in the vicinity when such work is being performed. 

Lethal hazard 

During the demagnetizing operation magnetic fields are present, which can lead to lethal heart rhythm disruptions for persons with active electronic implants  (e.g. heart pacemakers).

Rules of behavior/protective measures 

• Persons with such electronic implants should not work with the demagnetizing coil or remain in the vicinity when such work is being performed
• When demagnetizing ensure that no one with electronic implants is in the vicinity.
