Sec. 2. (a) This article 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 design, construction, installation, examination,
inspection, repair, and alteration of regulated boilers and unfired pressure vessels in Indiana.
(c) This article does not 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 specifically covered by the provisions in this section through 675 IAC 30-11-6 shall comply with the
applicable provisions of the ASME B&PVC and the NBIC, as adopted in section 1 of this rule.
(e) Any boiler or unfired pressure vessel not described in subsection (f) is regulated by this article, regardless of whether it is stationary,
portable, leased, rented, or owned and qualifies as a regulated boiler or pressure vessel as mentioned in IC 22-15-6-0.5. The vessels listed
in subsection (f) are exempted from the ASME B&PVC construction standards, inspection requirements, and operating permit
requirements.
(f) The following vessels are not regulated by this article:

(ii) a residential structure with fewer than seven (7) apartments; or
(iii) a place other than a place of public assembly, if not used for residential occupancy.
(B) Operated for heating purposes, either at a pressure not exceeding fifteen (15) psig, if qualifying as a steam boiler, or at a pressure not
exceeding thirty (30) psig, if qualifying as a hot water heating boiler.
(C) Having a gross output rating not exceeding two hundred fifteen thousand (215,000) Btu per hour.
(2) Exhibition traction engine boilers as defined in 675 IAC 30-4-16 or another boiler used solely for exhibition
purposes.
(3) Historical boilers as defined in 675 IAC 30-4-18.4.

(6) Model boilers as defined in 675 IAC 30-4-30.
(7) Vessels subject to federal regulation.
(8) Unfired pressure vessels installed before July 1, 1971, for which the volume of each chamber in the vessel is:
(A) fifteen (15) cubic feet or less, if located in a place other than a place of public assembly; or
(B) five (5) cubic feet or less, if located in a place of public assembly.
(9) Unfired pressure vessels, other than nuclear vessels, installed after June 30, 1971, if the volume of each chamber is:
(A) fifteen (15) cubic feet or less, if adequately protected by pressure relieving devices set to function at three hundred (300) psig 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) psig, 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.
(10) Unfired pressure vessels, other than nuclear vessels, that have each of their chambers protected by an adequate pressure relieving
device set to function at not over fifteen (15) psig.
(11) Unfired pressure vessels, other than nuclear vessels, where each of their chambers are operated entirely full of water, or other
liquid that is not materially more hazardous than water, if the temperature of the vessel's contents does not exceed one hundred eighty (180) degrees
Fahrenheit.
(12) Unfired pressure vessels used as part of a fire protection or suppression system regulated by another article of the commission's
rules.
(13) Unfired pressure vessels located on vehicles operating under the rules of other state agencies and used for carrying passengers
or freight.

(15) Unfired pressure vessels containing liquefied petroleum gases and regulated by another article of the commission's
rules.
(16) Unfired pressure vessels containing anhydrous ammonia that are used in transportation, distribution, or end-user 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 a refinery, utility, or manufacturing or processing plant.
(17) Unfired pressure vessels with a nominal capacity of no more than eighty-five (85) gallons that are used for the temporary storage
of chemical or nuclear waste.
(18) Unfired pressure vessels used as an integral part of an electrical circuit breaker.
(19) Unfired pressure vessels containing multiple chambers where each chamber meets one (1) of the criteria described in any of the
subdivisions of this subsection for an unfired pressure vessel.
(20) Domestic water heaters as defined in 675 IAC 30-4-15.
(21) Fired process heaters as defined in 675 IAC 30-4-18.1.
(22) Instant-on water heaters as defined in 675 IAC 30-4-25.1.
(23) Pool/spa heaters, either as defined in 675 IAC 30-4-38.1 or that are regulated by another state agency.
