Entrapment - Emergency Situation

In the Mumbai incident mentioned in the video, how long were two hospital employees pinned against the MRI scanner by an oxygen tank?. 30 minutes. 1 hour. Nearly 4 hours. 8 hours.

According to the video, why did a police officer's hand become trapped at the MRI scanner?. Her hand was stuck in the motorized patient table. Her hand was trapped between her service weapon (gun) and the MRI scanner. She was holding a metal clipboard that was pulled in. She was wearing a heavy metal watch that was attracted to the magnet.

What happened when an off-duty officer attempted to place his pistol on top of a cabinet in an MRI room?. The gun was safely secured. The gun was pulled into the device and spontaneously discharged a bullet into the wall. The gun became too heavy to lift but did not fire. The magnetic field caused the gun to jam permanently.

A steel oxygen tank weighing 10 lbs is pulled toward the magnet with a force of 1,500 times its weight. Approximately how many pounds of force does this represent?. 1,500 lbs. 5,000 lbs. 15,000 lbs. 150,000 lbs.

What is the definition of an MRI "Quench"?. A cooling cycle to prevent the magnet from overheating during a scan. The rapid boil-off of liquid helium to disable the magnetic field. A specialized cleaning procedure for the scanner bore. Turning off the electrical power to the technologist's computer console.

According to the video, in which specific situation should an emergency magnet quench be initiated?. If the computer software freezes during a patient scan. If a patient reports feeling claustrophobic inside the bore. If a person is pinned to the magnet by a ferromagnetic object that cannot be removed by one person. Whenever a fire alarm sounds in the hospital lobby.

How long does it typically take for the magnetic field to dissipate to a safe level after the quench button is pressed?. 5 to 10 seconds. 30 seconds to 2 minutes. Exactly 5 minutes. At least 15 minutes.

What physical danger is associated with the release of cryogen gas (helium) during a quench if the vent fails?. High levels of radioactivity in the room. Asphyxiation and severe cold burns. Risk of an electrical explosion. The floor becomes dangerously slippery from water condensation.

What should emergency responders do before entering the MRI scan room?. Run in immediately to address the emergency. Verify with MRI Personnel that it is acceptable to enter and undergo screening for metal. Turn off their radios and cell phones only. Wear a lead apron to block the magnetic field.

Why are MRI scanners considered "always on" unlike electromagnets in other industries?. Because they use liquid helium to cool energized copper windings, maintaining superconductivity without continuous external power. Because they are connected to a backup generator. Because the hospital is not allowed to turn them off by law. Because it takes 24 hours to turn the magnet back on once it is off.
