Currently, the fire department includes 38 pieces of equipment. All vehicles are radio equipped as part of the mutual assistance program covering Shelton and surrounding cities.

The Chairman of the Board of Fire Commissioners is appointed by the Mayor. The Board of Fire Commissioners, the Fire Chief and his assistants supervise the purchase of equipment and estimate the department's expenses for the coming year. The Fire Marshall and his deputies investigate suspicious fires, prepare fire reports and issue blasting and burning permits.

Except for the Fire Marshall, all of Shelton's firefighters are volunteers and at least 18 years old. 56% have earned a national certification of at least Firefighter 1 - the same held by professional firefighters. Some companies maintain a fire brigade, composed of 16 to 18 year-olds, that train as future volunteers.

The department is also actively involved in education and fire prevention. Fire prevention is highlighted annually during Fire Prevention Week when firemen visit schools and talk about fire safety. Once a year the Fire Marshall and his deputies also provide a complete fire safety inspection of all schools, factories and retail stores in the City.
