Final answer:
In the event of a fire, the most critical action is to remove the patient from the MRI equipment and ensure the safety of the technician. Other actions like addressing the power supply and cooling system are secondary to human safety. Patients and technicians should be familiar with the location of safety equipment like fire extinguishers in such emergencies.
Step-by-step explanation:
In the event of a fire, the first priority is to ensure the safety of human life. Therefore, the correct action would be to remove the patient and ensure that the technician is also safe. While it is important to shut down the power supply and attend to the cooling system to prevent damage to the equipment, these actions come after ensuring that all individuals are safe and out of harm's way. MRI equipment in such emergency scenarios should be handled by trained professionals who know how to safely power down the system to prevent additional hazards such as quenching, which involves the rapid vaporization of the liquid helium cooling the MRI magnets.
The MRI machine generates a large magnetic field to create detailed images, and the proper safety protocol, including how to evacuate the scanning room, should always be adhered to in the event of an emergency. Furthermore, individuals with pacemakers should avoid MRI scans as the strong magnetic fields could interfere with the functioning of the pacemaker. In case of fire, safety equipment locations like fire extinguishers and eyewash stations should be known to all personnel working in the vicinity. Also, if a patient experiences adverse symptoms such as dizziness or strange tastes during a scan, the procedure should be stopped and the patient should be assessed by medical professionals.
