Potential Workplace Hazards Associated with Magnetic Fields
The establishment of thorough and effective screening procedures for students is one of the most critical components that guards their safety when working in the MR environment. An important aspect of protecting students from MR system-related accidents and injuries involves an understanding of the risks associated with the various implants, devices, accessories, and other objects that may cause problems in this setting.
Before entering the MR environment or MR system room, students must remove all metallic objects including hearing aids, dentures, partial plates, keys, beeper, cell phone, eyeglasses, hair pins, barrettes, jewelry, body piercing jewelry, watch, safety pins, paperclips, money clip, credit cards, bank cards, magnetic strip cards, coins, pens, pocket knife, nail clipper, tools, clothing with metal fasteners, & clothing with metallic threads. Please consult the MRI program director or faculty if you have any questions or concerns.
