The Department of Fire Services helps local fire departments enforce state fire and electrical codes. We provide code compliance support across Massachusetts. We also issue licenses and permits for: boilers and pressure vessels, aboveground storage tanks, blasting and explosives, cannons and mortars, commercial hood cleaning, crowd managers, fireworks and special effects, fire extinguishers, and marine fueling. We administer licensing exams. DFS also provides plan reviews for self-service gas stations.
