A North Carolina commission authorizes an inspector to make inspections on boilers and pressure vessels and report on the suitability of said boilers and pressure vessels to the Chief Inspector. Those inspectors holding commissions as special inspectors shall be limited to making inspections on boilers and pressure vessels insured by their employer. Owner-user inspectors shall be limited to conducting inspections on boilers and pressure vessels operated by their respective employers.
A person seeking a commission from this State to conduct in-service inspections of boilers and pressure vessels must take and pass an examination on this Article and the rules adopted pursuant to this Article prior to receiving the commission. Any person who has had a commission in this State but who has been inactive for more than one year must take or retake and pass the State examination before conducting further in-service inspections of boilers and pressure vessels.
