About the Boiler Program

We insure public safety by performing safety inspections and issuing operating permits for more than 115,000 boilers and unfired pressure vessels throughout the state. State law requires a permit before you install, reinstall or move any boiler or unfired pressure vessel.

  • We investigate accidents involving boilers or pressure vessels.
  • We help owners, manufacturers, and repair firms understand the codes, rules and regulations.
  • We audit and review manufacturers of boilers and pressure vessels for conformance with national construction standards.
  • We administer national board and state examinations.


If you have any questions or need to report an accident, please contact the Boiler program.
