2 Installation and Operation Safety
Hazards Presented by the Magnetic Field
The strong magnetic field creates hazards because it strongly
attracts ferromagnetic metal alloys. Ferromagnetic metal
alloys contain iron, nickel, or cobalt. They are used in most
types of tools and equipment and in some surgical implants.
The strong magnetic field can cause the following hazards:
• Projectiles
• Displacement of surgical implants
• Stoppage of electrical and mechanical implants and
devices
If a loose metal object (such as a wrench or pen) gets too close to
the magnet, it can become a projectile as the force of the
magnetic field pulls the object towards the magnetic center. This
metal projectile can seriously injure anyone standing between it
and the magnet.
Ferromagnetic metals are sometimes used in surgical implants
and prosthetic devices. The magnetic field can twist metallic
implants out of place, causing tissue damage and pain to the
person in whom they are implanted, creating a life-threatening
situation. Some cardiac pacemakers, biostimulators, and
neurostimulators are mechanically activated and can stop in the
presence of the magnetic field. This situation can also create a
life-threatening situation.
