NAC455C.162. Removal of covering; inaccessible parts.

     1. If a boiler or pressure vessel is covered so that the longitudinal seams of shells, drums or domes cannot be seen, sufficient covering, setting wall or other form of casing or housing must be removed to permit reasonable inspection of the seams, rivets and other areas necessary to determine the condition and safety of the boiler or pressure vessel if the information cannot be determined by other means.

     2. If the inspector or special inspector, as the result of conditions disclosed at the time of inspection, requires the removal of the interior or exterior lining, covering or brickwork to expose parts of the boiler or pressure vessel not normally visible, the owner of the boiler or pressure vessel or his or her agent shall remove such material to permit a proper inspection to ascertain the thickness and condition of the covered areas.
