FORT BRAGG, N.C. (AP) - A family that went to the hospital with symptoms that suggested carbon monoxide poisoning has led military officials to warn dozens of families at Fort Bragg about possible exposure.

News outlets report military officials said Wednesday that a combination of factors caused the issue, including partially blocked air ducts that allowed carbon monoxide to build when the laundry room’s door was closed. The investigation began after the family’s hospital visit Aug. 4.

Fort Bragg Garrison Commander Col. Phillip Sounia says the base and housing contractor are working to find a permanent solution. The contractor will remove the laundry room doors on all affected homes and test unoccupied units this week.

Carbon monoxide is a gas that’s colorless, odorless and tasteless. It can be fatal because it displaces oxygen.
