Safety shall formulate regulations for the design, construction, installation, repair, use
and operation of boilers in Connecticut. Such regulations shall conform as nearly as
possible to the Boiler Code of the American Society of Mechanical Engineers, and the
National Board Inspection Code, both as amended, and shall prescribe requirements as
to the construction, installation, repair, use and inspection of boilers in the interest of
public safety. The Commissioner of Public Safety shall hold hearings for the purpose
of securing aid in the formulation of such regulations. Such hearings shall be public and
representatives of all parties interested shall be given an opportunity to be heard. Sec. 29-233. (Formerly Sec. 19-430). Department of Public Safety boiler inspectors. The Department of Administrative Services may call upon the Commissioner
of Public Safety to assist in formulating the examination requirements and the examination questions for candidates for the positions of boiler inspectors within the Department
of Public Safety. The Commissioner of Public Safety shall issue a commission as boiler
inspector to any person employed as boiler inspector who has been in the Department
of Public Safety after being appointed in accordance with the provisions of chapter 67
or certified as competent as a result of such examination. Sec. 29-234. (Formerly Sec. 19-431). Special inspectors. In addition to department boiler inspectors, the Commissioner of Public Safety shall, upon the application
of any company authorized to insure against loss from explosion of boilers in this state,
issue to any boiler inspectors of said company commissions as special inspectors, provided each such inspector before receiving his commission shall pass satisfactorily the
examination provided for in section 29-235. The Commissioner of Public Safety may
recognize in lieu of such examination a certificate of competency as an inspector of
boilers for a state that has a standard of examination substantially equal to that of the
state of Connecticut, or a commission as an inspector of boilers from the National Board
of Boiler and Pressure Vessel Inspectors. Such special inspectors shall receive no salary
from, nor shall any of their expenses be paid by, the state, and the continuance of a
special inspector's commission shall be conditioned upon his continuing in the employ
of such a boiler inspection and insurance company, and upon his maintenance of the
standards imposed by this chapter. Each such company shall promptly notify the commissioner of any special inspector's termination of employment. Such special inspectors
shall inspect all boilers insured by their respective companies, and the owners or users
of such insured boilers shall be exempt from the payment of inspection fees, as provided
for in this chapter. Each company employing such special inspectors shall, within fifteen
days following each internal inspection made by such inspectors, file a report of such
inspection with the Department of Public Safety upon appropriate forms as promulgated
by the Commissioner of Public Safety, who may use the standards of the American
Society of Mechanical Engineers. Sec. 29-235. (Formerly Sec. 19-432). Examination for special inspector's commission. Examinations for candidates for special inspectors' commissions shall be given
at least once each year by the Commissioner of Public Safety or by at least two examiners
appointed by said commissioner. All examinations shall be in writing, shall be uniform
for all candidates and shall be confined to questions formulated by the commissioner
and designed to determine fitness and competency as a boiler inspector. The written
examination may be supplemented by an oral examination or an interview by the commissioner or his designee which shall conform in general character with the written
examination. Each candidate whether he passes the examination or not shall be notified
by the board of his standing and grade as soon as possible after the examination has
been completed. If an applicant for a special inspector's commission fails to pass the
examination, he may appeal to the commissioner or his designee for a hearing on his
grade. The decision after such hearing shall be final, but an applicant who desires to
improve his rating shall have the right to take another examination within ninety days.
The record of an applicant's examination, whether original or modified after appeal,
shall be accessible to him and his employer. Sec. 29-236. (Formerly Sec. 19-433). Commission required. Suspension or revocation. Appeal. No person shall inspect boilers under this chapter unless he holds a
commission issued to him by the Commissioner of Public Safety as provided in this
chapter. This provision shall not apply to boiler inspectors in the state classified service
on October 1, 1953. Such commission may be suspended or revoked by the commissioner upon evidence of incompetency or untrustworthiness of the holder thereof or for
falsification of any matter or statement contained in his application or in a report of any
inspection. A person whose commission is suspended or revoked shall have the right
to appeal to the commissioner within two weeks after such suspension or revocation.
The commissioner or his designee shall hold a hearing on such appeal at which the
appellant may be present in person. Any person aggrieved thereby may appeal in accordance with section 4-183. Sec. 29-237. (Formerly Sec. 19-434). Inspection. All boilers included under this

The owner or user of a boiler required by this chapter to be inspected by the Commissioner of Public Safety or by state boiler inspectors shall pay to the commissioner at the
time of inspection a fee as follows: Sec. 29-239. (Formerly Sec. 19-436). Certificate required. Conformity to standards. No owner or user of a boiler shall operate such boiler under pressure in this state
without an operating certificate as provided for in section 29-238. Any person who
operates a boiler without such certificate or at pressure exceeding that specified in such
certificate shall be subject to the penalty provided by section 29-243. No boiler which
does not conform to the provisions of this chapter or to the boiler regulations formulated
or adopted by the board shall be installed in this state. All boilers shall be inspected during
construction by an inspector authorized to inspect boilers in this state or, if constructed
outside the state, by an inspector holding a commission from the National Board of Boiler
and Pressure Vessel Inspectors and a report of each such inspection made available to
the Commissioner of Public Safety. Said chapter shall not be construed as preventing
the use or sale of boilers in this state which have been installed or in use in this state
prior to October 1, 1953, and which have been made to conform to regulations for
existing installations. Sec. 29-240. (Formerly Sec. 19-437). Report of violations. Orders to comply.
