When working around an active MRI system, which of the following procedures outline an appropriate protocol?

A. Advise personnel regarding safety precautions in working around MRI systems, place warning signs demarcating the 5 gauss line, and schedule activities with the hospital that will induce vibration into the structure

B. Advise personnel regarding safety precautions in working around MRI systems, and require the hospital to shut down the MRI system whenever vibration will occur from construction

C. Understand the strength of the magnet, place warning signs demarcating the 5 gauss line, and provide an additional ground on the RF shield for added attenuation

D. Understand the strength of the magnet, place sensitive electronic equipment closest to the magnet, and place warning signs demarcating the 5 gauss line
