The following information was provided by the licensee via email:

"On February 17, 2024, a Honeywell employee experienced a non-work-related medical condition that required off site medical support. The incident occurred at approximately 2140 CST in the Feed Materials Building at the Metropolis facility. Due to the nature of the employee's condition, the individual was transported to [Massac Memorial Hospital in Metropolis, IL]. Honeywell health physics staff accompanied the injured employee, provided guidance to emergency room personnel, and controlled the facilities prior to decontamination. A whole-body survey of the employee and plant clothing was performed; the maximum amount of contamination present on the employee's coveralls was 65,500 disintegrations per minute (dpm) per 100 centimeters squared. All contaminated clothing was removed from the employee and an additional whole-body survey was performed; no contamination above background levels was detected. An emergency medical technician's (EMT) pants leg, boot, and the gurney wheels were found to be contaminated. The maximum amount of contamination present was 13,000 dpm per 100 centimeters squared. The EMT's pants leg, boot, and gurney were decontaminated to background levels. Following medical evaluation, hospital facilities were monitored and found to be free of contamination prior to release for unrestricted use. All contaminated materials from the hospital and injured employee were returned to the Metropolis facility.
