CAUTION
Accident hazard from pressurized air or nitrogen gas
There exists a small risk of injury when handling the gas supply of the iProbe incorrectly.
1. Pressurized air / nitrogen can enter the body via small skin injuries.
2. Pressurized air / nitrogen can cause eye injury or tinnitus.
u
Never cover the flush gas supply by hand.
u Wear protective googles and ear protection.
CAUTION
Danger of injury from tripping over dirt and scattered objects!
Dirt and scattered objects may cause people to slip or trip, resulting in personal injuries.
u
Always keep the work area clean.
u Remove objects which are no longer required from the work area and particularly from
the floor.
u Indicate unavoidable hazards using marking tape.
3.4.2 Dangers from Magnetic Fields
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.
The magnetic field of the device does not cause any personal injuries or property damage.
For further information see the manual of the magnet used.
