Siemens Healthineers disclaimers The information presented in this MR Safety – Level 1 presentation is for illustration only and is not intended to be relied upon by the reader for instruction as to the practice of medicine. Any healthcare practitioner reading this information is reminded that they must use their own learning, training, and expertise in dealing with their individual patients. This material does not substitute for that duty and is not intended by Siemens Healthineers to be used for any purpose in that regard. The MRI restrictions (if any) of the metal implant must be considered prior to the patient undergoing an MRI exam. MR imaging of patients with metallic implants brings specific risks. However, certain implants are approved by the governing regulatory bodies to be MR conditionally safe. For such implants, the previously mentioned warning may not be applicable. Please contact the implant manufacturer for specific conditional information. The conditions for MR safety are the responsibility of the implant manufacturer, not Siemens Healthineers. MR scanning has not been established as safe for imaging fetuses and infants less than two years of age. The responsible physician must evaluate the benefits of the MR examination compared to those of other imaging procedures. Disclaimers MR environment, safety zones, and safety labeling Untitled Slide The following section will discuss the M-R environment, safety zones, and safety labeling. ? MR environment Tab 1 Tab 1 Tab 1 Tab 1 Tab 2 Tab 2 Tab 2 Tab 2 Tab 3 Tab 3 Tab 3 Tab 3 Select each tab to review content. MR environment Select each of the tabs to review the MR enviornment. Tab 1 The Magnetic field is always on even when the M-R system is not being used to image patients, and, even when the M-R system electronics are turned off. The M-R-I Technologists determines who enters Zone three, the MR Controlled access room, and Zone four, the M-R scanner room. Anyone entering the M-R scanner room must be screened by the M-R-I Technologist to ensure it is safe for them to be in the M-R magnetic field to prevent any serious injury. Tab 2 The controlled access area is encompassed by the five-gauss line in the M-R magnet room and is typically marked on the floor. The five-gauss line in the M-R magnet room defines the controlled access area of the static magnetic field. Tab 3 The area leading to the M-R control and magnet room is clearly marked with signs and symbols. The M-R system owner is responsible for ensuring accessible areas in the vicinity, or adjacent areas of the M-R electromagnetic field are clearly identified with appropriate signs. These warning signs must be installed in a clearly visible area: On the door to the M-R Scan room at eye level On the floor in front of the M-R Scan room, or on Either side of the M-R scan room door. Depending on the M-R system, the field strength may also be displayed. Tab Slide Click on one of the tabs to display the corresponding content on this page. MRI Safety – Signs and Symbols The system owner is responsible for properly identifying the accessible areas (e.g., regarding the electromagnetic field), the vicinity of the MR system, as well as adjacent areas by using the appropriate signs. Warning signs installed must be in a clearly visible area. Door to the MR Scan room at eye level Floor in front of the MR Scan room door Either side of MR Scan room door Depending on the system, the field strength may also be shown (e.g., .55T, 1.5T, 3T, 7T). Reference:System_Owner_Manual_MAGNETOM_Sola_SAPEDM_CUT_N10VA51A_SOM_Sola_M11-01002G.629.08.01.02 MR 5-Gauss Line The controlled access area encompassed by the five-gauss line for the field strength is established around the MR magnet and is typically marked on the floor. The five-gauss line in the examination room defines the controlled access area of the static magnetic field. Reference: MR Safety – Introduction MR Safety – Siemens Video Magnet is always On The magnetic field is ALWAYS ON even when the MR system is NOT being used. The magnetic field is still ON, even if the MR system is turned OFF. The MRI Technologist has the final say in who is allowed to go into the MR scanner room (or) operating room where the MR scanner is located. The MR magnet field can cause serious injury or even death if proper procedures are not followed by all personnel entering the MR scanner [magnet] room. MR Safety Zones Z one I Zone II Zone III Zone IV + Zone I + Zone I + Zone I + Zone I + Zone I + Zone II + Zone II + Zone II + Zone II + Zone II + Zone III + Zone III + Zone III + Zone IV + Zone IV + Zone IV + Zone IV + Zone IV Reference: MR Safety | American College of Radiology (acr.org) MR Safety Zones the American College of Radiology has defined four safety zones within M-R-I facilities. Zones one through four correspond to the level of increasing magnetic field exposure and potential safety concerns. The area in Zone one, is freely accessible to the public. It is typically located outside of the M-R-I environment, in the M-R reception area or waiting room. Patients, health-care personnel, and other employees of the M-R-I facility have access to this area. Zone two, is the area that interfaces the publicly accessible uncontrolled Zone one and the strictly controlled areas of Zones three and four. Screening and ferromagnetic detection is often performed in Zone two, for example: the patient screening area, changing rooms, or where the office staff is located. Zone three, is the M-R controlled access area next to the M-R magnet room, for example: the M-R control room or computer room. This entrance has restricted access to the public and is controlled by installed key locks, access control cards, badges with Radiofrequency I-D, or similar technology to ensure access is limited to authorized personnel. These entrances are clearly marked so you can identify them with Caution, and restricted access signs. All individuals entering Zone three and four, including non-M-R personnel must be accompanied and under the supervision of M-R Level two personnel, except when in changing rooms and, or in the bathroom. Zone 4 Zone four is inside the M-R scan room, this is the physically walled confined area where the M-R scanner is located. This is generally located within a surrounded controlled access Zone three. The precise boundaries of Zone four and Zone three can be in flux depending on the clinical situation and configuration, for example: preoperative M-R. These areas should be clearly labeled as potentially hazardous due to the presence of a very strong magnetic field. The entry door should be closed to Zone four except when entering the room for patient examinations, or M-R system maintenance. It is also recommended to place a Caution barrier at the entrance to the M-R scanner room when the door is open. Inside MR scanner room (physical walled confines where a scanner is located). Generally located within a surrounding controlled access Zone III Precise boundaries of Zone IV and Zone III can be in flux depending on the clinical situation and configuration (e.g., preoperative MR) Should be clearly labeled as potentially hazardous due to the presence of a very strong magnetic field Entry door should be closed to Zone IV except for patient care or room/MR system maintenance It is recommended to place a Caution barrier at the entrance to the MR system room when the door is open Z one IV **Magnet is always ON** MR controlled access area, next to the MR Magnet room. Restricted access to the public by: using reliable key locks, access control cards/badges with radiofrequency ID (RFID), or similar technology to ensure access is limited to designated personnel Identify entrances with Signs: Caution, Restricted Access, etc. All individuals including non-MR personnel must be accompanied and/or under the supervision of MR Level 2 personnel while in Zones III and IV, except when in changing rooms, or in the bathroom This area is the interface between the publicly accessible, uncontrolled Zone I and strictly controlled areas of Zones III and IV. Screening and ferromagnetic detection is often performed in Zone II Patient screening area, patient changing rooms, office staff, etc. This area is freely accessible to the public: typically outside MR Environment where patients, health care personnel, and other employees of the MR facility access the MR environment MR reception area/waiting room MR Safety Zones Functional diagram Reference: ACR Manual on MR Safety Functional diagram This diagram is an example from the A-C-R Manual on M-R Safety. This is an idealized sample floor plan that illustrates site-access restriction considerations. Other potential M-R-related safety issues, such as M-R System site planning associated with magnetic-fringe–field considerations are not intended to be included herein. In any zone of the facility, there should be compliance with Health Insurance Portability and Accountability Act regulations regarding privacy of patient information. However, in Zone three, there should be a privacy barrier so that unauthorized persons cannot view the control panels. MR Conditional MR Unsafe MR Safe MR Safe, MR Conditional, MR Unsafe MR safety labeling Reference: ACR Manual on MR Safety MR safety labeling M-R Safety labelling consists of M-R Safe, M-R Conditional, and M-R Unsafe. MR Safe objects or devices pose no know hazards to a patient or individual in the M-R environment, without conditions. It is reserved for non-metallic and non-conducting objects that pose no known hazards in any M-R environment. MR Unsafe objects or device are known to present safety risks in the M-R environment. These objects or device are a contraindication for an M-R procedure and, or for an individual to enter the M-R environment. In the case of non-implanted devices, these are primarily ferromagnetic objects, for example, scissors, patient beds, gurneys, oxygen tanks, etc. Audio M-R Conditional objects or devices may or may not be safe for a patient undergoing an M-R procedure. These devices have shown that they pose no known hazards in a specified M-R environment with specific conditions of use. These decisions are based on published M-R Conditional, or safety claims that recognize that all such claims apply to the specifically tested static field and spatial gradient field strengths and only apply to the precise model, make, and identification of the tested device or object. Conditions defining the specified M-R environment include: Static Magnetic Field Strength. Spatial Gradients. Time rate of change of magnetic field. Radio Frequency Fields, and Specific Absorption Rate. Since M-R Conditional devices may present hazards, always refer to the manufacturer’s operator manual to avoid potential hazards and injuries. Conditions defining the specified MR environment include: Static Magnetic Field Strength Spatial Gradients dB/dt (time rate of change of magnetic field) Radio Frequency (RF) Fields Specific Absorption Rate (SAR) Electromagnetic fields Magnetic field In the examination room, there are different kinds of electromagnetic fields and the resulting risks that include: Static Magnetic Field Gradient Fields (or) Time-Varying Magnetic Field Gradient [dB/dt] Magnetic Field [B0] / Time-Varying RF Fields (or) Radiofrequency (RF) Fields [B1] Reference: System_Owner_Manual_MAGNETOM_Sola_SAPEDM_CUT_N10VA51A_SOM_Sola_M11-01002G.629.08.01.02 Electromagnetic fields In the M-R magnet room, there are different kinds of electromagnetic fields that pose certain risks, these include the: Static Magnetic Field. Gradient Fields (or) Time-Varying Magnetic Field Gradient, and the Magnetic Field [B-one]. Select each of the icons to discover more about the safety risks that must be considered with these fields. Static magnetic field The Static Magnetic Field [B0] is generated by a superconductive magnet and may extend beyond the examination room (i.e., walls, ceilings). The strong static magnetic field associated with the MR Magnet can interact with metallic objects, potentially turning them into dangerous projectiles. Spatial Field Gradient (SFG) Hazards: Rotational Force (Torque) causes the ferrous object to turn and align with the magnetic field direction. In terms of risk, rotational forces on objects are determined primarily by B0 field strength and are greatest at the center of the magnet. Translational Forces tend to be greatest near the edge of the magnet, where the Static Field Gradient is largest. As the ferromagnetic object approaches the face of the magnet bore, the translational forces can easily turn them into dangerous projectiles. To Minimize Hazards The controlled access area of the basic field is typically identified on the magnet room floor [0.5mT-Gauss line] Outside the controlled access area, the magnetic flux density is less than 0.5 mT Restrict access for personnel and objects into Zone IV, all personnel entering this environment must be thoroughly screened Reference: System_Owner_Manual_MAGNETOM_Sola_SAPEDM_CUT_N10VA51A_SOM_Sola_M11-01002G.629.08.01.02 Ferromagnetic Projectile Risks External [non-implanted] devices, objects, and equipment may be a projectile risk. All portable metallic or partially metallic objects entering Zone III or Zone IV must be labeled as MR Safe, MR Conditional, or MR Unsafe. Unsafe Transport Equipment [e.g., wheelchairs, Stretcher, Gurneys] should be tethered and fixed to an anchor point in Zone III. Portable Equipment in Zone IV objects should only enter Zone IV if required for immediate patient care [e.g., MR Conditional Ventilator, etc.]. The item should be labeled as MR conditional, and conditions clearly documented and communicated. Ferromagnetic Projectiles include: Oxygen tanks IV Pumps IV Poles Carts Stretchers, Gurneys Wheelchairs Monitoring equipment [e.g., Pulse Oximeter, ECG lead] Stethoscopes Needles Scissors Knife Cell phone Guns And more… Reference: ACR Manual on MR Safety Static magnetic field In the M-R magnet room, The Static Magnetic Field [B-zero] is generated by a superconductive magnet and may extend beyond the examination room, for example, the walls, and ceilings. The strong static magnetic field associated with the M-R Magnet can interact with metallic objects, potentially turning them into dangerous projectiles. Spatial Field Gradient (SFG) Hazards include: Rotational Force (Torque), that can cause the ferrous object to turn and align with the magnetic field direction. In terms of risk, rotational forces on objects are determined primarily by the b-zero field strength and are greatest at the center of the magnet. Translational Forces, tend to be greatest near the edge of the magnet, where the Static Field Gradient is largest. As the ferromagnetic object approaches the face of the magnet bore, the translational forces can easily turn them into dangerous projectiles. To Minimize Hazards, limit access in these areas to M-R Level two authorized personnel: The controlled access area of the basic field is identified on the magnet room floor. The point-five-milli-Tesla-Gauss line. Outside the controlled access area, the magnetic flux density is less than point-five-milli-Tesla. Restricted access for personnel and objects into Zone four, all personnel entering this environment must be thoroughly screened. In the M-R magnet room, there are different kinds of electromagnetic fields.

Restricted access for personnel and objects into Zone four, all personnel entering this environment must be thoroughly screened. In the Static Magnetic Field there is a potential risk of Ferromagnetic projectiles. Ferromagnetic Projectiles are external [non-implanted] devices, objects, and equipment that can become a projectile risk. All portable metallic or partially metallic objects entering Zone three or Zone four must be labeled as M-R Safe, M-R Conditional, or M-R Unsafe. Unsafe Transport Equipment, such as, wheelchairs, Stretchers, and Gurneys should be tethered and fixed to an anchor point in Zone three. Portable Equipment in Zone four objects should only enter Zone four if required for immediate patient care, for example, M-R Conditional Ventilator, oxygen tanks, etc. The item should be labeled as M-R conditional, and conditions clearly documented and communicated to all personal. Ferromagnetic Projectiles include, Oxygen tanks, I-V Pumps, I-V Poles, Carts, Stretchers, Gurneys, Wheelchairs, Monitoring equipment [e.g., Pulse Oximeter, E-C-G leads], Stethoscopes.

Acoustic noise safety Hearing protection Noise safety Select the arrows on the left, to learn more about the acoustic noise safety considerations with these types of electromagnetic fields.. acoustic noise safety layer Appropriate hearing protection must be worn by patients and volunteers that lowers the noise to at least ninety-nine decibels. The Siemens headphones provided with the M-R system are not classified as hearing protection. The Siemens standard headphones are only intended for communication with the patient and should be used in combination with earplugs. All personnel should be trained to correctly apply hearing protection, and any personnel accompanying a patient in the examination room must also wear hearing protection during the examination that lowers the noise to at least eighty-five-decibels. [for example: nurses, anesthesiologists, and any other personnel in the M-R scanner room]. It is mandatory to provide anesthetized or unconscious patients with hearing protection. Hearing protection for these patients should not be omitted even at moderate sound levels. Neonates and infants, require special attention and training of personnel is required to ensure that hearing protection is properly positioned. Researchers and veterinarians should also use hearing protection for animals during an M-R-I exam. If the patient refuses hearing protection, facilities should have a process and procedure in place to discuss the risks of proceeding without hearing protection and they may even consider canceling the exam. hearing protection layer To properly insert the ear-plugs perform the following steps: With clean hands, roll and compress the foam earplug. Hold the ear plug between thumb and forefinger. Roll and progressively compress the entire tapered end of the earplug to a small, crease-free, cylinder. Reach hand over head and gently pull ear upward. Insert the foam earplug. Hold for at least twenty-to-thirty seconds as the foam earplug expands.

Cosmetics containing metallic particles (e.g., eye makeup, magnetic eyelashes, glitter hair spray, bobby pins, etc.). Metallic drug patches. Face masks should not include any metal in the nose pieces or fibers incorporated into the mask. Preliminary safety screening Preliminary safety screening Aids in the prevention of scheduling patients that may be inappropriate candidates for MR examinations. Alerts that the patient has an implant or device, so the implant or device can be verified if MR Safe, MR Conditional, or MR Unsafe [e.g., pacemaker, aneurysm clip, cochlear implant, etc.] Schedule patients on the correct magnet [e.g., cardiac exams, breast exams] Screens patients for claustrophobia, so medication can be requested from their ordering physician in preparation for the MR examination Special considerations are needed for pediatric patients, minors, and mentally impaired patients Pregnant patients Imbedded metal fragments from military activities Permanent make-up Reference: MR Safety | American College of Radiology (acr.org) Preliminary safety screening The preliminary safety screening, aids in the prevention of scheduling patients that may be inappropriate candidates for M-R examinations. It alerts the M-R Technologists, that the patient has an implant or device, so the implant or device can be verified if it is M-R Safe, M-R Conditional, or M-R Unsafe, for example if they have a M-R unsafe pacemaker, aneurysm clip, cochlear implant, etc. It allows the facility to schedule patients on the correct magnet, for example, for a cardiac exams, or breast exam. It screens patients for the claustrophobia, so medication can be requested from their ordering physician in preparation for the M-R examination. It brings awareness to the M-R Technologists in case there are any special considerations, for example, a pediatric patient, a minor, pregnant, or mentally impaired patient. Let’s the M-R technologist know if there is any imbedded metal fragments from military activities, or if the patient has permanent make-up. Comprehensive safety screening Reference: MR Safety | American College of Radiology (acr.org) Comprehensive Safety Screening Written or electronic MR screening form is essential to prevent unsafe exposure to Zone IV in the MR environment for any personnel. This includes patients, guardians, research participants, MR personnel, non-MR personnel, and ancillary staff. MR Level 2 personnel reviews the screening form with the patient, guardian, research participant, non-MR personnel, or ancillary staff. Printed or electronic form to document the screening procedure All questions must be answered [yes or no], no empty responses are accepted, additional information requested must be provided Patient, guardian, research participant, etc., and the MR Level 2 personnel performing the screening must both physically or electronically sign the completed safety screening form after the interview Safety Screening Form should become part of the individual’s medical record Additional written or verbal information for inclusion on a screening form must be provided by a physician or an advanced practice provider or another reliable source and documented in writing [e.g., knowledge about specifics related to an implanted device] Comprehensive safety training Audio Comprehensive Safety Screening consists of a written or Electronic M-R Screening form. It is essential to prevent unsafe exposure to Zone four in the M-R environment for any personnel. This includes patients, guardians, research participants, M-R personnel, non-M-R personnel, and ancillary staff The M-R Level-two personnel then reviews the screening form with the patient, guardian, research participant, non-M-R personnel, or ancillary staff. This can be either a printed or electronic form documenting the screening procedure. All questions must be answered [yes or no], no empty responses are accepted, additional information requested must be provided. The patient, guardian, research participant, etc., and the MR Level-two personnel performing the screening must both physically or electronically sign the completed safety screening form after the interview. Then the M-R Safety Screening Form should become part of the individual’s medical record. Additional written or verbal information for inclusion on a screening form must be provided by a physician or an advanced practice provider or another reliable source and documented in writing. For example, knowledge about specifics related to an implanted device. Patient screening form https://www.acr.org/Clinical-858 Resources/Radiology-Safety/MR-Safety. Patient screening form Pediatric, minors, and teenagers, should be screened twice by Level 2 MR Personnel: Once, in the presence of parents or guardians Second time, separately, to maximize the possibility that all potential dangers are disclosed Screening Pediatric and Minor Patients These patients are required to complete a written or electronic MR Safety screening questionnaire prior to entering Zone III. At least one of these screenings must be performed by Level 2 MR Personnel verbally and/or interactively with the patient. Screening Conscious, Nonemergent Patients All MR Personnel must undergo initial on boarding MR screening. A yearly review of MR safety screening must be performed. Significant changes in screening status must be reported to the MRMD immediately before returning to the MR environment. Screening Staff/Personnel Screening Screening additional patients & personnel Untitled Slide Audio When screening staff or when preforming personnel screening, remember that all M-R Personnel must undergo initial onboarding and M-R Screening. A yearly review of M-R Safety screening must be performed. Any significant changes in screening status must be reported to the M-R-Medical-Director immediately before returning to the M-R environment. When screening conscious, or non-emergency patients, remember that these patients are required to complete a written or electronic M-R Safety screening questionnaire prior to entering Zone three. At least one of these screenings must be performed by Level-two M-R Personnel verbally and, or interactively with the patient. When screening pediatric and minor patients, remember that pediatric, minors, and teenagers, should be screened twice by Level-two M-R Personnel. They must also be screened, in the presence of parents or guardians and then screened again separately to maximize the possibility that all potential dangers are disclosed. All pediatric, minor, and teenage patients are recommended to change into M-R Safe pocketless garments to ensure that no metallic objects, toys, or other unsafe items enter Zone four. Emergency patients and their accompanying non-MR Personnel may be screened only once by Level 2 MR Personnel. In cases of extenuating circumstances, there must be an agreement between the ordering physician and the MR MD acknowledging the risks of a decision not to screen prior to proceeding. Screening Emergency Patients If deemed appropriate to accompany or remain with the patient, companions should be screened using the same criteria as anyone else entering Zone IV. Screening Companions in Zones III and IV Screening of Unconscious, Unresponsive, Altered-Consciousness, Mentally Impaired Patients Family members or guardians of these patients that have appropriate knowledge should complete a written or electronic MR safety screening questionnaire prior to the patient entering Zone III. Screening additional patients & personnel If no reliable patient history can be obtained, and if the requested MR examination cannot reasonably wait until a reliable history might be obtained it is recommended that these patients be physically examined and undergo plain-film radiography as necessary to exclude potentially harmful embedded or implanted metallic foreign bodies, implants, or devices. Screening of Unconscious, Unresponsive, Altered-Consciousness, Mentally Impaired Patients Untitled Slide When screening unconscious, unresponsive, altered-consciousness, or mentally impaired patients, the family members or guardians that have appropriate knowledge should complete a written or electronic M-R safety screening questionnaire prior to the patient entering Zone three. If no reliable patient history can be obtained, and if the requested M-R examination cannot reasonably wait until a reliable history might be obtained it is recommended that these patients be physically examined and undergo plain-film radiography as necessary to exclude potentially harmful embedded or implanted metallic foreign bodies, implants, or devices. When screening emergency patients, the emergency patient and their accompanying non-M-R Personnel only need to be screened once by Level-two M-R Personnel. In cases of extenuating circumstances, there must be an agreement between the ordering physician and the M-R Medical Director acknowledging the risks of a decision not to screen prior to proceeding. When screening companions in Zones three and four, it is deemed appropriate to accompany or remain with the patient. These companions should be screened using the same criteria as anyone else entering Zone four. Safety in alternative MR environments MR Systems are increasingly being operated in alternative environments outside of conventional diagnostic facilities. Each of these represents unique challenges regarding MR Safety, particularly regarding unique devices, procedures, personnel, site-access restrictions, screening, site contamination, infection control, and adverse event management. Alternative MR Environments include: PET/MR MR Interoperative & Interventional MR-guided Radiation Therapy Specialized personnel with MR safety training and specific training to the workflows and procedures in these alternative environments is recommended. Reference: MR Safety | American College of Radiology (acr.org) Safety in Alternative MR Environments M-R Systems are increasingly being operated in alternative environments outside of conventional diagnostic facilities. Each of these represents unique challenges regarding M-R Safety, particularly regarding unique devices, procedures, personnel, site-access restrictions, screening, site contamination, infection control, and adverse event management. Alternative M-R Environments include: PET/M-R M-R Interoperative and Interventional, and M-R-guided Radiation Therapy Specialized personnel with M-R safety training and specific training to the workflows and procedures in these alternative environments is recommended. The M-R Medical Director at these facilities should ensure there are specific Standard-Operating-Procedures in place defining roles and responsibilities for the M-R Personnel. Standard-Operating-Procedures should include: Identification of the responsible person to ensure the safety of the patient, M-R Personnel, and other personnel who may care for the patient while in these alternative environments. Personnel working in the M-R Environment should have a minimum of Level-one M-R Training or be supervised by Level-two M-R Personnel. Processes to educate all other personnel who need access to Zone four should be developed, for example, for nurses, anesthesiologists, respiratory technologists, surgeons, etc. Personnel working in an alternative M-R environment should have a minimum of Level-one M-R training or be screened and directly supervised by Level-two M-R Personnel. In a PET and M-R environment, M-R Safety and radiation regulatory requirements often have and require shared responsibilities between the two medical directors [M-R Medical Director and the nuclear medicine authorized user]. In the intraoperative and interventional M-R environment, policies and procedures must clearly indicate which specific Level-two M-R Personnel are responsible for overseeing M-R safety. For mobile M-R scanners, siting may be associated with additional challenges around M-R Zone restrictions. At seven-Tesla, the risk of accidents due to projectiles or complications related to implanted devices substantially increases. M-R Conditional status at seven-Tesla cannot be assumed from existing M-R Conditional status at three-Tesla or other field strengths. Point of Care MRI Systems have a lower risk of missile-effect projectile incidents. However, there is insufficient data to assess safety related to scanning in the presence of active implanted medical devices and other devices. All involved staff, including non-M-R Personnel, should follow appropriate safety procedures.

In case of emergency, the relevant switch should be pressed.... Select the numbers to review each switch, its effect, and the emergency it should be used for.... The Magnet Stop, shuts down the static magnetic field. This is also referred to as a Quench. A Quench is only performed in emergencies related to accidents with attracted metal parts. For example, a patient gurney, cart, is attached to the magnet. Or in cases where physical harm may occur, for example, patient trapped between gurney and magnet, or in case of a fire. The Emergency Shut-down, switches off the electric power to the entire M-R system, however, it is important to note that the magnet remains at field. The Emergency Shut-down switch is used in emergencies related to fire. The Table Stop, halts the motorized table movement. This is used in emergencies, related to accidents, or related to injury due to table movement. Always, follow the instructions regarding which switches should be used in case of emergency.

Magnet stop switch 2. Magnet stop switch on alarm box Magnet stop switch (Quench) The Magnet Stop Switch triggers a controlled Magnet Quench. During a quench, the super-conductivity of the magnetic field is shut down. However, the M-R System is not disconnected from the power. The Liquid helium (coolant) boils off rapidly and is released outside via an exhaust vent line. The escape of helium may be noisy (loud roaring noise) due to high gas flow. There are two different locations for the Magnet Stop switch on the M-R System. The individual magnet stop switch removes the static magnetic field. The magnet stop switch on the alarm box, also removes the static magnetic field. Both locations for the magnet stop switches quench the magnet and should only be used in cases of an EMERGENCY. After the Magnet Stop [Quench], switch is pressed, a WARNING LED will light up and an alarm signal will sound. The formation of droplets due to condensation during a quenching is dangerous. The quench creates dangerously high pressure and displaces oxygen from the room. This can cause asphyxiation and hypothermia is induced within a very short time. Personal injury may include, for example frostbite. So, it is important that you don’t touch the exhaust line or quench pipe and that you do not stand under the exhaust line. Immediately evacuate all personnel from the Magnet Room and remove the patient or volunteer from magnet bore and the magnet room. Restrict all access to the examination room and notify the Siemens Healthineers Customer Service Engineer and the Siemens Customer Care Center following a quench. Only Siemens authorized personnel can put the magnet back into operation. After the Magnet Stop [Quench] switch is pressed, a WARNING LED will light up and an alarm signal will sound.

Fire All facilities should provide MR Safety training to educate the local fire marshals, firefighters, police, and security personnel about potential hazards of responding to emergencies in the MR Magnet room [Zone IV]. It should be assumed in the event of a fire or other emergency in Zone IV, that the magnetic field is present, fully operational, and potentially dangerous. Free access to Zone III and IV by firefighters or other Non-MR Personnel with air tanks, axes, crowbars, or other firefighting equipment might prove catastrophic or lethal to responders. Reference: MR Safety | American College of Radiology (acr.org) MR Staff Response to Fire Rescue any personnel in danger only if safe to do so Activate the nearest Alarm, call to provide specific information about the event Contain fire by closing ALL doors or the room/are, including fire doors MR Conditional fire extinguisher may be used to control the fire, only if it is safe and that personnel have been properly trained Evacuate if instructed to do so by the fire department If a fire is in the magnet room [Zone IV] and cannot be contained by an in-room sprinkler or by safe use of an MR Conditional fire extinguisher, the fire department will require access to the room. In this instance, the magnet should be QUENCHED to avoid potentially serious injury to any personnel or damage to the MR equipment or scanner MR Emergency procedures - Fire MR personnel, safety officers, and cleaning Untitled Slide The following section will discuss M-R personnel & safety officers, along with cleaning precautions and recommendations. MR Level 1 & 2 personnel American College of Radiology (ACR) definitions Non-MR personnel Patients, visitors, or facility staff who don’t meet the criteria of Level 1 or Level 2 MR personnel.
