Boilers Licenses

The Boiler Program is in charge of issuing Boiler permits and performing inspections for boilers and pressure vessels in the State of Washington. The Boiler Program currently offers two licenses related to Boiler work; Boiler and Pressure Vessel Inspector and Boiler Operator

For inspectors, the Program issues a work card through The Department of Labor & Industries, which allows an inspector to perform work within the state. As for the Boiler Operator license, a license is not needed in the State of Washington. Nonetheless, three cities are the exception to this since they require a valid license to perform Boiler work. These cities, along with their licensure information and contact numbers, are listed below:
