The Sandy Hook fire company was formally established in 1938, and among the five independent volunteer companies in town, that responds to most of the calls. The company has 75 regular members and eight in the junior corp. There also is a Ladies Auxiliary support group for the company.
It is the only fire company in town with two stations—the main one at 18-20 Riverside Rd. and a substation at 249 Berkshire Rd. The fire chief is Bill Halstead, who also is the town's fire marshal and a former fire chief at Fairfield Hills Hospital during the time the institution was opened.
Volunteers meet twice a month, the second Sunday and fourth Monday. Classes are frequently held in topics, such as ice rescue, rope rescue and medical response.
