When as a result of an external inspection or a determination by other objective means, it is the Inspector's opinion that continued operation of the boiler or pressure vessel constitutes a menace to public safety, the Inspector may request an internal inspection or an appropriate pressure test or both to evaluate conditions. In such instances the owner or user shall prepare the boiler or pressure vessel for such inspections or test as the Inspector designates.
