DNREC's Boiler Safety Program has the responsibility of overseeing the construction, installation and repair of all boilers and pressure vessels that are installed in the State of Delaware, except those exempted by Title 7, Chapter 74B, located in a "place of public assembly."

• Brought under the Department of Public Safety, the name was changed to the Division of Boiler Safety in 1972.
• The Division of Boiler Safety was organizationally moved under the Department of Natural Resources and Environmental Control on July 1, 2003.
