Fairbanks, AK – Nearly two dozen Anchorage-based soldiers were treated in Fairbanks on Thursday

for carbon monoxide exposure they sustained during a morning field training exercise.

The soldiers, paratroopers from the 4th Infantry Brigade Combat Team (Airborne), 25th Infantry

Division at Joint Base Elmendorf-Richardson, were in a multi-day exercise at the Yukon Training

Area near Eielson Air Force Base when they began to show symptoms, according to an Army news

release.

Carbon monoxide is a colorless, odorless gas produced by combustion that causes headaches,

dizziness and potentially loss of consciousness and death in cases of prolonged exposure.

None of Thursday’s cases appear to be life threatening, said Army spokesman Lt. Col. Alan Brown.

There’s no reason to believe additional soldiers, including Fairbanks-based soldiers, sustained carbon monoxide poisoning, he said.

The Army is still investigating the cause of the exposure.

“It’s too early in the investigation to be able to say definitively, so I wouldn’t want to speculate at this time,” Brown said.

The soldiers were driven to Bassett Army Community Hospital at about 9:30 a.m.

Among the 21 soldiers who showed symptoms, four were admitted to the hospital and seven were

released.

Eight patients are awaiting lab results and two were still being evaluated Thursday evening. The

soldiers who were released from the hospital will spend the night at Fort Wainwright and will rejoin

their units Friday, Brown said.
