WARNING:
Medical implants, such as aneurysm clips, surgical clips or
prostheses may contain ferromagnetic materials and therefore would be
subject to strong forces near a magnet. THIS COULD RESULT IN INURY
OR DEATH. In the vicinity of rapidly changing field (e.g. pulsed gradient
fields), eddy currents may be induced in the implant resulting in heat
generation.
iii.
WARNING:
Metal materials in someone's body as a result of an old
injury may be affected by magnetic fields in this facility. THIS COULD
RESULT IN INURY OR DEATH.
iv.
WARNING:
Large attractive forces may be exerted on equipment
brought near to the magnet. The force may become large enough to
move the equipment uncontrollably towards the magnet. Pieces of
equipment may become projectiles and large equipment (e.g. gas
bottles, power supplies) could trap bodies or limbs between the
equipment and the magnet. EITHER TYPE OF OBJECT MAY CAUSE
INJURY OR DEATH. The closer to the magnet you get, the larger the
force is. The larger the mass of the equipment the larger the force pulling
it.
v.
CAUTION:
The operation of equipment may be directly affected by the
presence of large magnetic fields. Items such as watches, tape
recorders, and cameras may be magnetized and irreparably damaged if
exposed to magnetic fields. Information encoded magnetically on credit
cards and magnetic tape including computer floppy discs, may be
irreversibly corrupted. Electrical transformers may become magnetically
saturated. Safety characteristics of equipment may also be affected.

Superconducting magnet systems are complex systems with the
potential to seriously injure personnel or equipment if not operated
according to procedures. The use of cryogenic liquids in these systems
is only one factor to consider in safe and proper magnet system
operation. Proper use of safety mechanisms (pressure relief valves,
rupture disks, etc.) included in the cryostat and top plate assembly are
necessary. Furthermore, an understanding of the physics of the magnet
system is needed to allow the operator to properly control the large
amounts of energy stored in the magnetic field of the superconducting
coil. The Model 430 Programmer has been designed with safety
interlocks to assist the operator in safe operation, but these designed-in
features cannot replace an operator’s understanding of the system to
ensure the system is operated in a safe and deliberate manner.
