WARNING
Risk to life 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.
u Mark the magnetic field of more than 0.5 mT (5 Gauss) before start up.
u
Keep people with active medical implants or heart pacemakers away from the 0.5 mT
(5 Gauss) area.
u
The permanent workplace of employees must be outside the 0.5 mT (5 Gauss) area.
u
Do not stay or work at magnetic fields of more than 8 T.
u Prevent exposure of more than 200 mT for more than 8 h/day.
u Keep disks, credit cards and electronic devices away from the identified area.
u
Do not use ferromagnetic tools or items within the identified area.
u
Only use non-ferromagnetic transportation dewars or pressure cylinders for the
cryogenic agents.
u
Only use non-ferromagnetic ladders or steps.
u Remove magnetic items (jewelry, watches, pens etc.) before carrying out maintenance
work.
WARNING
Danger of injury or material damage due to strong magnetic fields!
Injury or material damage may result due to the strong magnetic fields that can draw metallic
objects towards the magnet.
u DO NOT locate the instrument next to large iron-containing objects or near moving
metallic objects.
u DO NOT place any iron-containing object on the minispec magnet unit. Be aware that
the magnetic field can erase magnetic recording media such as computer diskettes or
credit cards.
u DO NOT place these items or clothing containing these items on the magnet unit.
u
Leave the dust cover on the probe canal when the instrument is not in use.
