  • Reason
    One facility reported to ge on february 21, 2016, about a magneto quench event with subsequent release of cryogen gas into the magnet room. at this facility, the magneto heater probe connection disconnected. this resulted in the accumulation of ice inside the magnet, blocking the venting of the cryogen. as the ventilation was blocked by ice, the quench back of the magnet caused the gas to be released into the magnet room. the occurrence of the fault described in this notification can generate ice accumulation inside the magnet, blocking the cryogenic ventilation, which may cause the cryogenic gas to release into the magnet room. this release may result in a critical oxygen deprivation for users and patients. however, the danger situation is detectable due to the intense sound generated by the magneto quench, allowing the opportunity for evacuation or response of the emergency professionals before the occurrence of an injury.
