Safety
2.6 Residual Risks
In the following section, the residual risks from the risk analysis are summarized.
To prevent health hazards and hazardous situations obey all safety instructions and
warnings in the manual.
Electricity
Magnetic Field
WARNING
Risk of damage to life and limb due to electricity.
Risk of damage to life and limb due to contact with electrical lines and damaged
insulation.
Thus:
• Work on electrical equipment must be done by an approved electrical technician.
• Keep moisture away from electrical lines to prevent short-circuits.
• Check the magnet system accidental ground before start up.
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 metal implants. Ferromagnetic tools in the magnetic field are
significantly hazardous. Disks and electronic devices may be damaged. Duration of
exposure (8 h/day) above the limit of 200 mT can cause damage to health.
Thus:
• Do not use ferromagnetic tools or items within the identified area.
• Mark the magnetic field of more than 0.5 mT (5 Gauss) before start up.
• The workplace must be outside the 0.5 mT area.
• Only use safety shoes with non-ferromagnetic toe caps.
• Keep people with pacemakers and metal implants away from the identified area.
• Keep disks, credit cards and electronic devices away from the identified area.
• Only use transport dewars of non-ferromagnetic material for the cryogenic agents.
• Only use non-ferromagnetic ladders or steps.
