Are you an owner or operator of an antique boiler?If so, you need to know that the adoption of National Board Inspection Code (NBIC) Appendix “C” became effective January 1, 2006. In an effort to enhance antique boiler safety, the Washington State Board of Boiler Rules in conjunction with Department of Labor & Industries’ Boiler Section has adopted the inspection criteria for historical boilers in the NBIC. The following rule covers antique boiler safety: WAC 296-104-102 Inspections, What are the standards for in-service inspection? (2) The standard for in-service inspections of historical boilers of riveted construction preserved, restored, or maintained for hobby or demonstration use, shall be Appendix “C” of the National Board Inspection Code as referenced in subsection (1) of this section. The requirements from the NBIC, 2004 Edition, NBIC C2020, Recurring Inspection Requirements for antique boilers are: A. Annual visual internal and external inspection. B. Annual visual inspection of fusible plugs to determine the condition of the threads in the crown sheet and on the fusible plugs. C. Annual hydrostatic test at a pressure at least equal to MAWP up to 1.25 MAWP, but in no case shall the test pressure exceed 1.25 times MAWP by more than 6%. D. Every five years ultrasonic thickness testing. E. Additional testing and examination as deemed necessary by the inspector. Over the years, many of you have become accustomed to most of these inspection requirements and we have appreciated your much-needed cooperation. With the adoption of the NBIC Appendix “C,” we will also require all antique boilers granted a Washington State Special to have a third-party ultrasonic examination. This will be necessary every five years, so if your boiler has not had this non-destruction exam done in the last five years, you will need to make sure it is completed and documented. Please recommend the Boiler Room to other boiler professionals. They can sign up here to receive it via e-mail. - Linda Williamson, Acting Boiler Chief |
