    Its a Pass, Fail, or Not Applicable methodology, boiler with 9 sq ft heating area might pass one case but would fail the other if 20kw were applied.

    Here am I thinking state governments area PITA and we only have 6 plus 2 territories.

    I certainly don't envy you guys with 50 plus a federal district.

    Bob,
    To make matters worse there are boilers regulated by the Federal Government.
    Locomotive boiler law is in CFR Chapter 49. (Code of Federal Regulations)
    Merchant ship boilers are in CFR Chapter 46 these are the ones I worked on.

    I have never located the regulation for Navy ships or other government installations.
    I mean who repairs the boilers at Fort Knox or Area 51?

    The whole point of this thread is to locate any exemptions for model boilers in the state codes.
    Notice the similarity between the language from the Texas code and the Missouri code.

    Texas exemption:
    3) manually fired miniature boilers that:
    (A) are constructed or maintained for locomotives, boats, tractors, or stationary engines only as a hobby for exhibition, recreation, education, or historical purposes and not for commercial use;
    (B) have an inside diameter of 12 inches or less or a grate area of two square feet or less; and
    (C) are equipped with a safety valve of adequate size, a water level indicator, and a pressure gauge;

    Missouri exemption:
    (4) Steam boilers of a miniature model locomotive or boat or tractor or stationary engine constructed and maintained as a hobby and not for commercial use, having an inside diameter not to exceed twelve inches and a grate area not to exceed one and one-half feet and that is equipped with a safety valve of adequate capacity, a water level indicator and a pressure gauge;

    How many other states are using the same rules? This thread has not located exemptions for even half of the US States yet.

    The head in the sand approach has never worked well for me... :big: your milage may vary.

    Any help reading this code stuff is very welcome.

    Thanks
    Dan

    Gee it was 1966 but the term USN Buships publications comes to mind.

    For UK/Oz BR 3000 and BR 3001 (BR=Book of Reference).

    BR 3000 is the what when book. BR 3001 is the how book.

    Strangely they are 12":1' models.

    Hope this Helps

    Best Regards
    Bob

    1988 c 254 § 20; 1983 c 3 § 174; 1972 ex.s. c 86 § 2; 1951 c


    Main that seems to cover all hobby use


    79.070 Existing installations—Conformance
    required—Miniature hobby boilers. (1) All boilers and
    unfired pressure vessels which were in use, or installed ready
    for use in this state prior to the date upon which the first rules
    and regulations under this chapter pertaining to existing
    installations became effective, or during the twelve months
    period immediately thereafter, shall be made to conform to
    the rules and regulations of the board governing existing
    installations, and the formulae prescribed therein shall be
    used in determining the maximum allowable working pres-
    sure for such boilers and unfired pressure vessels.
    (2) This chapter shall not be construed as in any way pre-
    venting the use or sale of boilers or unfired vessels as referred
    to in subsection (1) of this section, provided they have been
    made to conform to the rules and regulations of the board
    governing existing installations, and provided, further, they
    have not been found upon inspection to be in an unsafe con-
    dition.


    (3) An inspection certificate may also be granted for
    miniature hobby boilers that do not comply with the code
    requirements of the American society of mechanical engi-
    neers adopted under this chapter and do not exceed any of the
    following limits:
    (a) Sixteen inches inside diameter of the shell;
    (b) Twenty square feet of total heating surface;
    (c) Five cubic feet of gross volume of vessel; and
    (d) One hundred fifty p.s.i.g. maximum allowable work-
    ing pressure, and if the boiler is to be operated exclusively not
    for commercial or industrial use and the department of labor
    and industries finds, upon inspection, that operation of the
    boiler for such purposes is not unsafe. [2009 c 90 § 2; 1995 c
    41 § 1; 1993 c 193 § 1; 1951 c 32 § 7.]




    So for this State a certificate/inspection is required with the key word MAY be granted


    Robert



    Edit:

    70.79.320 Operating without inspection certificate
    prohibited—Penalty. (1) It shall be unlawful for any per-
    son, firm, partnership, or corporation to operate under pres-
    sure in this state a boiler or unfired pressure vessel, to which
    this chapter applies, without a valid inspection certificate as
    provided for in this chapter.
    (2) The department may assess a penalty against a person
    violating a provision of this chapter. The penalty shall be not
    more than five hundred dollars. Each day that the violation
    continues is a separate violation and is subject to a separate
    penalty.
    (3) The department may not assess a penalty until it
    adopts rules describing the method it will use to calculate
    penalties for various violations.
    (4) The department shall notify the violator of its action,
    and the reasons for its action, in writing. The department
    shall send the notice by certified mail to the violator that a
    hearing may be requested under RCW 70.79.361. The hear-
    ing shall not stay the effect of the penalty. [2005 c 22 § 6;
    1986 c 97 § 2; 1951 c 32 § 31.]



    Operate a home built without paying the fees and the SHALL notify which without a consequence for failure makes it meaningless, WILL become a fine to transfer coin from your pocket to the States

    Robert,
    I had spotted the exemption but missed the penalty which is considerable at $500 per day.

    I added the references to the first post.

    Here is another section of the Washington code that states construction must conform to the rules.

    70.79.060 Construction, installation must conform to
    rules—Inspection certificate. (1) Except as provided in
    subsection (2) of this section, no power boiler, low pressure
    boiler, or unfired pressure vessel which does not conform to
    the rules and regulations formulated by the board governing
    new construction and installation shall be installed and operated
    in this state after twelve months from the date upon
    which the first rules and regulations under this chapter pertaining
    to new construction and installation shall have
    become effective, unless the boiler or unfired pressure vessel
    is of special design or construction, and is not covered by the
    rules and regulations, nor is in any way inconsistent with
    such rules and regulations, in which case an inspection certificate
    may at its discretion be granted by the board.
    (2) An inspection certificate may also be granted for
    boilers and pressure vessels manufactured before 1951 which
    do not comply with the code requirements of the American
    Society of Mechanical Engineers adopted under this chapter,
    if the boiler or pressure vessel is operated exclusively for the
    purposes of public exhibition, and the board finds, upon
    inspection, that operation of the boiler or pressure vessel for
    such purposes is not unsafe. [2009 c 90 § 1; 1984 c 93 § 1;
    1951 c 32 § 6.]

    Thanks Terry,

    That exemption is very similar to TX only we do not need an ASME stamp on the safety valve. I added the info to the first post.

    The current official Pennsylvania stance is there will be NO exemption based on size. They're saying all boilers operation in public (over 15psi) need a state inspection.

    In Ohio, they seem not inclined to bother those with barrels less than 16"

    Allen,
    What is the source of this information? Is that from a Pennsylvania boiler inspector?

    This might cause some of the model shows to rethink their policy. Cabin Fever has always had a Gauge 1 live steam track in operation and G1 boilers have been mostly ignored by state officials.

    It came direct from the guy who supervises the inspectors here in Western, Pa. Our local inspector inquired the end of July to see if my roller actually needed inspection, since it doesn't in Ohio.

    Cabin Fever, and the various ride on live steamer groups, have pretty much been "flying under the radar". Something which is not really an option at an antique machinery show when the inspector is already there anyway.

    The gauge 1 guys can always try to argue they are "toys", but larger stuff might not fare so lucky if they ever come to the communewealth's attention.

    The ghost of John Payton is very much still with us....

    I think every hobby machinist has at one time wanted to use live steam. It's all good until that creeping feeling of knowing you are next to a potential bomb makes you appreciate a good old air pump. Personally, I'd rather be trained by someone that really knows how to operate a boiler!

    I still haven't heard of any incident where someone has actually blown a model up. With reasonable precautions, correct safety components, decent construction, and a responsible operator its likely to be statistically safer than driving with a cell phone or gasing up your car.

    Don't forget that while your boiler may fit an exemption in your home state it may not in the state where you are showing it. As an example, some rules seem to exempt boilers with an operating pressure of under 150 psi but others seem to exempt at under 100 psi. :wall:

    The definition of "Model Boiler" is now online for Indiana:

    680 IAC 2-1-2 Title; scope; applicability; definition

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

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

    680 IAC 2-4-30 "Model boiler" defined
    Authority: IC 22-13-2-8
    Affected: IC 22-12-4; IC 22-15-6
    Sec. 30. "Model boiler" means any boiler that does not exceed any of the following limits:
    (1) Two (2) cubic feet total gross volume (exclusive of casing and insulation).
    (2) One and one-half (1 1/2) square feet of grate area.
    (3) One hundred (100) psig maximum allowable working pressure.

    I can not figure out how to modify the first post of this thread to add the exemption. Could someone with ADMIN privileges add the exemption and definition to the state of Indiana in the first post.

    Thanks
    Dan
