Ohio Rev. Code Ann. § 4104.15 – Certificates of inspection and operation

(A) All certificates of inspection for boilers, issued prior to October 15, 1965, are valid and effective for the period set forth in such certificates unless sooner withdrawn by the superintendent of industrial compliance. The owner or user of any such boiler shall obtain an appropriate certificate of operation for such boiler, and shall not operate such boiler, or permit it to be operated unless a certificate of operation has been obtained in accordance with section 4104.17 of the Revised Code.
(B) If a boiler owner or user is in compliance with sections 4104.13, 4104.17, and 4104.18 of the Revised Code, the superintendent, upon application, shall issue the boiler owner or user a certificate of operation or renew the boiler owner's or user's certificate of operation. The certificate of operation shall:
1. (1) State the maximum pressure at which the boiler may be operated, as ascertained by the rules of the board of building standards, the name of the owner or user, the location, size, and number of each boiler, and the date of issuance;
2. (2) Be so placed as to be easily read in the engine room or boiler room of the plant where the boiler is located, except that the certificate of operation for a portable boiler shall be kept on the premises and shall be accessible at all times.
(C) If an inspector at any inspection finds that the boiler or pressure vessel is not in safe working condition, or is not provided with the fittings necessary to safety, or if the fittings are improperly arranged, the inspector shall immediately notify the owner or user and person in charge of the boiler and shall report the same to the superintendent who may revoke, suspend, or deny the certificate of operation and not renew the same until the boiler or pressure vessel and its fittings are put in condition to insure safety of operation, and the owner or user shall not operate the boiler or pressure vessel, or permit it to be operated until such certificate has been granted or restored.
(D) If the superintendent or a general boiler inspector finds that a pressure vessel or boiler or a part thereof poses an explosion hazard that reasonably can be regarded as posing an imminent danger of death or serious physical harm to persons, the superintendent or the general boiler inspector shall seal the pressure vessel or boiler and order, in writing, the operator or owner of the pressure vessel or boiler to immediately cease the pressure vessel's or boiler's operation. The order shall be effective until the nonconformities are eliminated, corrected, or otherwise remedied, or for a period of seventy-two hours from the time of issuance, whichever occurs first. During the seventy-two-hour period, the superintendent may request that the prosecuting attorney or city attorney of Franklin county or of the county in which the pressure vessel or boiler is located obtain an injunction restraining the operator or owner of the pressure vessel or boiler from continuing its operation after the seventy-two-hour period expires until the nonconformities are eliminated, corrected, or otherwise remedied.
(E) Each boiler which has been inspected shall be assigned a number by the superintendent, which number shall be stamped on a nonferrous metal tag affixed to the boiler or its fittings by seal or otherwise. No person except an inspector shall deface or remove any such number or tag.
(F) If the owner or user of any pressure vessel or boiler disagrees with the inspector as to the necessity for shutting down a pressure vessel or boiler or for making repairs or alterations in it, or taking any other measures for safety that are requested by an inspector, the owner or user may appeal from the decision of the inspector to the superintendent, who may, after such other inspection by a general inspector or special inspector as the superintendent deems necessary, decide the issue.
(G) Neither sections 4104.01 to 4104.20 of the Revised Code, nor an inspection or report by any inspector, shall relieve the owner or user of a pressure vessel or boiler of the duty of using due care in the inspection, operation, and repair of the pressure vessel or boiler or of any liability for damages for failure to inspect, repair, or operate the pressure vessel or boiler safely.
