The investigation attributed the cause of this accident to user error, in that the safety manual instructions and the posted magnet safety signage were not observed and followed.The magnetic field near the magnet is strong enough to attract metal objects with great force, potentially causing serious injury or death.This is a well-recognized risk among mri system users.Furthermore, warning signs depicting the risk of magnetization of objects were posted appropriately at the mr facility when the incident occured.The technician sustained injuries to his hands and right rib.No additional injuries were reported, and he was able to continue working the next work day, (b)(6) 2019.No corrective action is necessary for this case because the accident resulted from a secondary user error.The user should not have tried to remove the floor polisher from the magnet after it was initially magnetized.The product safety manual states, "do not attempt to remove a ferromagnetic object attracted by the magnet if the magnet is still in the energized state.Even if the object can be removed, it may be pulled to the magnet again or move in an unexpected manner, resulting in a further accident." as a preventative action, the manufacturer will give an mr safety video to the affected facility for use during staff training, and will ask the facility to manage the mri room door-lock for untrained personnel, such as cleaning workers.
