Section 680IAC2-1-2. Title; scope; applicability; definition

   (a) This rule shall be known as the Indiana Boiler and Pressure Vessel Rules.

  (b) The purpose of this article shall be to specify minimum standards that govern the construction, installation, inspection, and repair of regulated boilers and unfired pressure vessels in Indiana.

  (c) This article does not presume to limit in any way the builder's right to choose any method of design or form of construction that conforms to the standards prescribed, or provided for in this article, as such standards cover certain fundamental features of construction and leave a number of details to the judgment of designers and acceptance of inspectors.

  (d) Any condition not covered by this article shall comply with the applicable provisions of the ASME code or the API-ASME code.

  (e) "Regulated boiler or pressure vessel" refers to any part of a boiler or pressure vessel not described in subsection (f). The vessels listed in subsection (f) are exempted from both ASME standard construction and periodic inspection by the boiler and pressure vessel safety section of the department of homeland security.

  (f) The term "regulated boiler or pressure vessel" does not include any of the following:

(1) Water heaters commonly known as domestic water heaters having a size and heat input that do not exceed that specified by the rules board.

(2) Pressure vessels other than nuclear vessels operated entirely full of water or other liquid that the rules board specifically found to be not materially more hazardous than water, if the temperature of the vessel's contents does not exceed one hundred eighty (180) degrees Fahrenheit.

(3) Boilers and pressure vessels under federal regulation.

(4) Pressure vessels meeting the requirements of the Interstate Commerce Commission for shipment of liquids or gases under pressure.

(5) Air tanks located on vehicles operating under the rules of other state authorities and that are also used for carrying passengers or freight.

(6) Air tanks installed on the right-of-way of railroads and used directly in the operation of trains.

(7) Pressure vessels that were installed before July 1, 1971, and that have a volume of:

(A) fifteen (15) cubic feet or less if located in a place other than a place of public assembly; and

(B) five (5) cubic feet or less if located in a place of public assembly.

(8) Pressure vessels, other than nuclear vessels that were installed after June 30, 1971, and that have a volume of:

(A) fifteen (15) cubic feet or less, if adequately protected by pressure relieving devices set to function at three hundred (300) pounds per square inch or less and located in a place other than a place of public assembly;

(B) five (5) cubic feet or less if adequately protected by pressure relieving devices set to function at two hundred fifty (250) pounds per square inch or less and located in a place of public assembly; or

(C) one and one-half (1 1/2) cubic feet or less regardless of pressure or location, unless otherwise covered by this article.

(9) Pressure vessels, other than nuclear vessels protected by adequate pressure relieving devices, set to function at not over fifteen (15) pounds per square inch gauge.

(10) Pressure vessels containing liquefied petroleum gases and regulated by the commission.

(11) Surgical sterilizers, coffee urns, and steam jacketed food cookers that do not exceed size limits specified by the rules board.

(12) Commercial toy boilers and miniature model boilers constructed as a hobby that do not exceed a size specified by the board.

(13) Pressure vessels containing anhydrous ammonia, used in transportation, distribution, or use storage of the product as a liquid fertilizer, and for which a general scheme of construction, installation, and safety requirements has been adopted by statute or rule of another state agency. This exemption does not apply to vessels in refineries or in manufacturing or processing plants.

(14) Nuclear vessels for the collection and disposal of nuclear waste from a nuclear energy system that are not subject to pressures greater than would prevail if they were vented to the atmosphere.

(15) Standard and miniature traction engine boilers and other boilers used solely for exhibition purposes.

(16) A locomotive boiler used only on a railway that is used as a tourist attraction.
