Darien Fire/EMS Department recently placed five personal thermal imaging cameras in service for crew members. The thermal imaging cameras where purchased using funds donated by Thelma Meyer in memory of her late husband, Darien Fire Department Captain Richard Sawyer. During the years that Captain Sawyer served with the Darien Fire Department no one would have dreamed of being able to see through smoke, but today that is a reality for every firefighter responding on the fire engine in Darien, said Darien Fire Chief Justin Schuenke.
