12 Hospitalized After Carbon Monoxide Poisoning At Credit Union

ODENTON, Md. (WJZ) -- Twelve people were taken to area hospitals after what Anne Arundel County Fire officials believe was a carbon monoxide poisoning.

County firefighters responded to the Navy Federal Credit Union at 1179 Annapolis Road sometime after 8 a.m. Tuesday for a report of workers experiencing symptoms associated with carbon monoxide poisoning.

The construction crews said around 5 a.m. they worked and used a propane-powered saw for about two to three hours in the building.

Some of the workers started to feel ill and they called 911.

Firefighters identified carbon monoxide levels as high as 850 parts per million inside the building, according to officials. Carbon monoxide levels above 800 parts per million can cause headache, nausea, and dizziness after 45 minutes, collapse and unconsciousness after one hour and death within 2-3 hours.

Six people were taken to Shock Trauma to be treated in their hyperbaric chamber, while six others were taken to University of Maryland Medical Center to treat various symptoms.

The victims are 11 men and 1 woman, ranging in ages from 22 years old to 55 years old.

Three of the patients transported had symptoms that were serious, but not believed life-threatening and the other patients had possibly serious symptoms.

Anne Arundel County Fire officials remained on scene to help ventilate the building.

Staff who work at the Navy Federal Credit Union began reporting for work before 9 a.m. but were denied entry into the building while ventilation was completed.

Around 9:45 a.m. there were no carbon monoxide readings in the credit union and the building was turned over to the branch staff.
