Material damage hazard to iPhone phones from helium gas
If you have an iPhone 7 or newer model, you’ll need to take special care in environments
where elevated levels of helium in the air can occur, e.g. when cooling magnet and/or during
magnet quenches.
u Follow the user instructions provided for the iPhone by Apple.
u Keep your iPhone out of range of the magnet system, liquid helium transport dewars or
gas cylinders.
2.5 Earthquake Safety
In regions where there is a potential risk of earthquakes, additional precautions should be
taken to reduce the chance of personal injury or property damage through movement or tip-
ping of the magnet.
Many countries or regions have documented regulations, including building codes, regarding
earthquakes. Before installing a magnet system, it is highly advisable that you check with lo-
cal authorities on whether your area is prone to earthquakes and if there are any regulations
in effect.
If the installation site is regarded as an earthquake area, please contact Bruker for informa-
tion on earthquake securing equipment.
2.6 Safety from Nearby Construction
In a magnet system hazards come basically from two sources:
• Mechanical breakdown of the mounting suspension in the magnet system.
• Quench as a result of mechanical movement of the superconductor and as a result the
magnet reaching a critical temperature.
No permanent damage results from the mechanical movement of the superconductor, how-
ever when the suspension is damaged, it must be repaired.
These amplitudes are mainly in the vertical direction. For permanent faults we give a maxi-
mum peak value of 0.01 g (0.0981 m/s
2
) for systems with activated ADI or API dampers. Un-
damped systems can be operated up to a maximum of 1 mg or 9.81 mm/s

. NMR measure-
ments are not possible in these vibration entries.
For short term accelerations, which can occur during earthquakes, we have experienced that
the NMR magnet systems survive a strength of 6.0 or accelerations up to 0.2 g > 90%.
2.7 Country-Specific Safety Regulations
In addition to the above safety precautions, any country-specific safety regulations for operat-
ing NMR systems must be fulfilled. These may include, for example, regulations on:
• Facilities of a controlled access area around the magnet.
• Working conditions at computer stations.
• Use of anesthesia gases.
• Handling of laboratory and transgenic animals.
