• To free jammed parts of the body (e.g. hands, ngers, feet), pull apart components that are
clamped together.
– Do this using the non-magnetic hammer to drive the non-magnetic wedges into the
separating rift.
– Release the jammed body parts.
• If necessary, call the emergency medical service or an emergency physician.
Material damage caused by strong magnetic elds
NOTICE
Data loss caused by strong magnetic elds
If you are close to a secondary section (< 150 mm) any magnetic or electronic data medium as
well as electronic devices that you are carrying can be destroyed. For example, credit cards, USB
sticks, oppy disks and watches are at risk.
• Do not carry any magnetic/electronic data media and no electronic devices when you are
close to a secondary section!
