Dedham is served by a volunteer fire department with 26 active members, all of whom have obtained Firefighter 1 certification. The department has two pumper tankers and two four-wheel drive quick attack vehicles, stored in its two fire houses.
As a department, the members play an active role in the Dedham community. In addition to working the annual Dedham celebration as a unit, the fire department also coordinates parking for town functions and mounts the city's Christmas decorations. It has hosted CPR classes and Carroll County Fire Association's meetings.
