SAFETY INSTRUCTIONS
Magnetic bridge
Harmlessness of magnet fastenings
The Federal Office for Radiation Protection explains as follows, in
response to the frequently asked question of whether magnetic
clips on name badges are harmless:
The wearing of small permanent magnets on the body, in the form
of, for example, magnetic clips for name badges is generally not
damaging to your health. This use leads only to very limited local
exposure to weak static magnetic fields. Normal use of such mag-
netic clips is no way near sufficient to trigger the adverse biological
effects that we are all familiar with. Small permanent magnets
may however interfere with certain types of coronary pacemaker.
From approx. 1 mT magnetic flux density upwards, it is possible
that magnetic cards, credit cards, watches etc. are also affected.
It is therefore advisable not to wear the name badge directly
above an implanted pacemaker and not to store sensitive
magnetic cards in jacket pockets.

We recommend that all carriers of pacemakers
use the fastening system pins and clips instead
of magnetic version. Credit and magnet cards
should not be kept in the vicinity of magnets.
