The Annadale Hose Company 1 serves Clinton Township in northern Hunterdon County. In 1891, a major fire destroyed 23 buildings on Main St. neighboring Clinton. At that time, residents didn't have fire protection other than a bucket brigade made up of the towns people. Firefighters from Flemington, Phillipsburg, and Easton Pennsylvania responded to assist the towns people who were battling the blaze with bucket brigades. Flemington firefighters responded with manpower only and no apparatus, and it took two hours for fire apparatus and firefighters from Phillipsburg and Easton to arrive. The citizens of Clinton and Clinton Township petitioned to start their own fire departments. In 1897, the Annandale Hose Co. 1 was formed with 16 volunteer members enrolled. When the department was formed they responded with a hand-drawn hose cart from the Hummer Brothers carriage house. It wasn't until 1925 when the department purchased its first motorized fire engine a Ford Model T.

Today, the Annandale Fire Hose Company operates nine pieces of fire apparatus out of two firehouses. The department also maintains a 1944 Mack Type 45 pumper as a parade piece.
