Notes
Hawaii regulates boiler and pressure vessel safety under HIOSH. Boiler inspectors require licensure, but individual boilermakers (installers/repairers) may not require a separate state occupational license. Verify current requirements with HIOSH, as Hawaii's requirements for boilermaker workers may differ from inspector licensing.
