WARNING
Risk of damage to persons and property due to not readable signs and
labels.
Signs and labels with advice may become not readable.
Thus:
• Maintain signs and labels in a readable state.
• Replace damaged or not readable signs and labels immediately. New signs and
labels can be ordered from Bruker Service.
WARNING
Risk of damage to life and limb due to high magnetic fields.
A magnetic field of more than 0.5 mT (5 Gauss) is life-threatening for people with
pacemakers or active metal implants. Exposure to more than 8 T can cause damage
to health. Duration of exposure (8 h/day) above the limit of 200 mT can cause
damage to health. Ferromagnetic tools in the magnetic field are significantly
hazardous. Disks and electronic devices may be damaged.
Thus:
• Mark the magnetic field of more than 0.5 mT (5 Gauss) before start up.
• Keep people with active medical implants away from the 0.5 mT (5 Gauss) area.
• The permanent workplace of employees must be outside the 0.5 mT (5 Gauss)
area.
• Do not stay or work at magnetic fields of more than 8 T.
• Prevent exposure of more than 200 mT for more than 8 h/day.
• Keep disks, credit cards and electronic devices away from the identified area.
• Do not use ferromagnetic tools or items within the identified area.
• Only use non-ferromagnetic transportation dewars or pressure cylinders for the
cryogenic agents.
• Only use non-ferromagnetic ladders or steps.
