The National Board of Boiler and Pressure Vessel Inspectors is the worldwide leader in pressure equipment safety. It was established in 1919 to promote greater safety to life and property through uniformity in the construction, installation, repair, maintenance, and inspection of pressure equipment. National Board members are the chief boiler and pressure vessel inspectors representing most states and all provinces of North America, and many major cities in the United States. Members oversee adherence to laws, rules, and regulations related to pressure equipment.
