(430 ILCS 75/10) (from Ch. 111 1/2, par. 3211)
    Sec. 10. Inspection of boilers and pressure vessels.
    (a) Each boiler or pressure vessel used or proposed to be used within this State, except boilers or pressure vessels exempt under this Act or rules and regulations of the Board, shall be thoroughly inspected as to its construction, installation, condition, and operation as follows:
        (1) Power boilers shall be inspected annually both
internally and externally while not under pressure and shall also be inspected annually externally while under pressure if possible; provided that any power boiler or steam generator, the operation of which is an integral part of or a necessary adjunct to other continuous processing operations, shall be inspected internally at such intervals as are permitted by the shutting down of the processing operations. The Board may provide by rules and regulations for extension of time within which power boilers are required to be inspected based upon type, function, or manner of operation.
        (2) Low pressure steam, hot water heating, and hot
water supply boilers shall be inspected biennially as required by the rules and regulations of the Board.
        (3) Traction steam engine boilers and other boilers
constructed before the effective date of this amendatory Act of 1992 and operated solely for exhibition purposes may be issued an inspection certificate by the Chief or Deputy Inspector, provided the owner can establish and document that the design, materials, fabrication, examination, testing, and operation are in accordance with the rules and regulations of the Board. Traction engine boilers and other boilers used solely for exhibition purposes shall be inspected every 2 years.
        (4) Pressure vessels subject to internal corrosion
shall receive a certificate inspection every 3 years as required by rules and regulations of the Board. However, the standards of inspection and repair of pressure vessels in service by an owner-user authorized under Section 15 shall, at the option of the owner-user, be either (1) the applicable rules and regulations in the National Board Inspection Code, or (2) the applicable section in the American Petroleum Institute API-510, "API Recommended Practice for Inspection, Repair, and Rating of Pressure Vessels in Petroleum Refining Service".
        (5) Pressure vessels not subject to internal
corrosion shall receive certificate inspection at intervals set by the Board, but internal inspection shall not be required of pressure vessels containing materials that are known to be noncorrosive to the material of which the shell, heads, or fittings are constructed, either from the chemical composition of the materials or from evidence that the materials are adequately treated with a corrosion inhibitor, provided that the vessels are constructed in accordance with the rules and regulations of the Board.
    A grace period of 2 months beyond the period specified in this Section may elapse between internal inspections of a boiler while it is not under pressure and between external inspections of a boiler while it is under pressure. The Board may, in its discretion, permit longer periods between certificate inspection.
    The inspections herein required shall be made by the Chief Inspector, a Deputy Inspector, or a Special Inspector provided for in this Act.
    (b) If at any time a test is deemed necessary for a stated cause by the inspector, the owner or user shall perform a test acceptable to the inspector in the presence of and under the direction of the inspector.
    (c) All boilers and pressure vessels, except those otherwise exempted by the Board, shall be inspected during construction, as required by the applicable rules and regulations of the Board, by an inspector authorized to inspect boilers and pressure vessels in this State or, if constructed outside of the State, by an inspector holding a Certificate from the National Board of Boiler and Pressure Vessel Inspectors or a Certificate of Competency as an inspector of boilers and pressure vessels for a jurisdiction that has a standard of examination substantially equal to that of this State as provided in Section 9.
