Boilers and Pressure Vessels

The primary objective of the DNREC Boiler Safety Program is to protect the public from unsafe boilers, pressure vessels. It does so by providing registration and inspections of boilers and pressure vessels under the state’s Boiler Safety Regulations.

The program, part of the DNREC Division of Waste and Hazardous Substances, ensures that boilers and pressure vessels meet state regulations and current American Society of Mechanical Engineers (ASME) standards when manufactured and when repairs are made.

The program is charged with maintaining minimum standards of inspector competency and professionalism. It provides inspections of boilers and pressure vessels, maintains data on boilers and pressure vessels in Delaware, monitors complaints brought against inspectors and advises the department on the development of related rules and regulations.

Delaware has had a boiler safety program in place since 1919, when the Board of Boiler Rules was created. In 1972, the function was moved to the state’s Dept. of Public Safety. It was moved to DNREC in the early 2000s.
