A firefighter has been taken to the hospital for evaluation following a two-alarm house fire in Danbury.  Firefighters responded to Carriage Lane shortly after 8am yesterday.  Responding firefighters reported heavy smoke throughout the house.  Tankers from West Redding, Georgetown and Ridgefield responded with mutual aid due to the lack of hydrants in the area.  A medic was also called to the scene.  The cause of the fire is under investigation.  The 7 occupants were displaced and were assisted by American Red Cross Connecticut. The firefighter has since been released from the hospital.
