Lacey Berry's manual on safety trainingGeneral InformationRisks associated with the MRI lab:Used properly, the magnetic resonance imaging equipment contained within the MRI lab is quite safe, however, it poses serious risks to the unwary. Users of the lab should be completely familiar with this manual and with the procedures for protecting others from hazards. To minimize risks to subjects and other members of the research team, only personnel who have successfully completed the full CAMRI safety certification process are allowed access to the MR scan rooms, control rooms or equipment rooms. Observers who have not been safety trained are not permitted to enter the MRI suites without special prior arrangements. The main hazards in the lab are: • The “projectile effect” when heavy, sharp, or dangerous objects are hurled into the instrument. Even seemingly innocuous objects, such as hand tools, can be lethal. • Pacemaker damage. Certain cardiac pacemakers can be damaged by exposure to magnetic fields, causing direct hazards to subjects. Under no circumstances should persons with pacemakers enter the MRI suites at CAMRI. • As in many laboratories, the MRI lab contains wiring and circuitry that operate at dangerous voltages. Under no circumstances should users touch any exposed wiring, or any exposed terminals in the equipment cabinets. • Grossly improper scanner operation could result in excessive heating of the subject due to RF energy being deposited. This is easily avoided by operating the equipment according to the guidelines contained in the user manuals and set by the individual instructors. • Suffocation: in extreme cases, the imaging magnet may release large volumes of helium gas that can rapidly force all air out of the scan room. Normally, the helium gas would be vented through the roof. However, there is a small but significant risk that the venting system could fail.
