Carbon monoxide causes evacuation of The Bridge homeless shelter in Dallas

The Bridge homeless shelter was evacuated Sunday morning due to carbon monoxide.

Dallas Fire-Rescue crews were called to the scene just before 11 a.m. for a medical call.

While treating the person for the initial call, others started complaining about feeling sick.

Firefighters then tested the area for carbon monoxide, and got a positive reading.

Everyone inside the homeless shelter, about 200 people, were evacuated as a precaution.

There were more than a dozen people transported to the hospital, including four Dallas Fire-Rescue members.

The gas was shut off, and crews worked to ventilate the “Welcome Building.”
