When firefighters arrived, one side of the duplex was engulfed with heavy smoke and flames coming from the front window.

All residents got out of the home safely, but Ambulance NB assessed one man.

One side of the duplex is destroyed, while the other has water and smoke damage.

The Canadian Red Cross is assisting four residents.
