Introduction
Safety Warnings
WA R N I N G
This device produces a high magnetic field. The stray field
surrounding the magnet extends far beyond the confines of the
vessel. The existence of this field produces several hazards. In
particular, make sure people with cardiac pacemakers avoid the
region of field. The FDA guideline for cardiac pacemakers is
currently 5 gauss. Fields higher than this can cause malfunction of
the pacemaker. The field will interfere with sensitive electronic
devices and will erase magnetic storage devices such as tapes
and credit cards.
WA R N I N G
Ferromagnetic objects in the vicinity of the magnet will become
magnetized and will be attracted toward the magnet. The force on
such objects is proportional to their mass so that even large
objects will move toward the magnet with considerable velocity.
WA R N I N G
Under fault conditions, it is possible for large amounts of helium
and/or nitrogen to be released from the system (for example,
during a magnet quench). Under these conditions, the gas is very
cold and can cause “cold burns”. If the gas is not vented properly,
asphyxiation is possible due to the displacement of oxygen within
the room. It is the responsibility of the user to ensure adequate
venting of the gas is provided and adequate ventilation within the
final installation site.
N O T E
It is the responsibility of the user to take all necessary precautions to
prevent accident or loss from use of the magnet. Agilent Technologies
accepts no responsibility for any loss or damage caused either directly or
indirectly from use of the magnet. Every effort is made that the information
contained in this manual is correct. However, Agilent Technologies
accepts no responsibility for any inaccurate statements or omissions.
