Boiler and Pressure Vessel Safety Inspections


Proposed new rules.  The Boiler and Pressure Vessel Board has proposed several rule changes.  Among the proposals are updated references to national codes and new recordkeeping requirements for certain repairs.  To view the changes, click here.

The Iowa Division of Labor regulates boilers and unfired steam pressure vessels according to Iowa Code Chapter 89.  Some hot water heating boilers used for pools or spas are regulated by the Iowa Department of Public Health.

If you have a covered boiler or pressure vessel you must make sure it is inspected by a state inspector or an authorized insurance company inspector.  Ten-day notice of new installations must be provided pursuant to Iowa Code Section 89.6.  Click here for a 10-day notice form.  Certain repairs and alterations must be authorized in advance by an authorized inspector.  Covered objects must be inspected by state inspectors or authorized insurance company inspectors.

You may request the Boiler and Pressure Vessel Board review an inspection report, grant a variance from a rule, or change a rule.  Click here for more information about the Boiler and Pressure Vessel Board.
