   (a)   Persons witnessing tests of gas piping systems in accordance with §27-921(b) of the Administrative Code, other than authorized plumbing inspectors of the Department of Buildings, shall be acceptable to the Commissioner of Buildings and shall meet the following prerequisites:
      (1)   Be either a registered architect, licensed professional engineer, licensed master plumber, or employee of a utility company; and,
      (2)   Have at least five years experience in inspection and testing of gas piping systems, or hold a current master plumbers license.
   (b)   The witnessing of the test in accordance with §27-921 and these rules shall be in person by the specifically designated person on the list maintained by the Commissioner. This authorization may not be delegated to anyone, nor can persons under his supervision witness the test in his behalf.
   (c)   Authorized persons on the list shall be required to maintain liability insurance of an amount acceptable to the Department.
   (d)   Failure of authorized persons to require compliance with law and these rules, and/or submission of a false statement will be grounds for immediate suspension or revocation of an authorized representative's authority to conduct inspections on behalf of the Department, and the immediate suspension of a Master Plumber License; be cause for immediate referral to the Division of Professional Conduct of the State Education Department, in the case of Architects or Engineers; and be cause for immediate referral to the Public Service Commission, in the case of utility companies.
   (e)   Reports of the inspections or tests are required to be submitted, and shall be made on forms acceptable to the Department.
   (f)   No reports shall be accepted for any installations for which a prior permit has not been previously obtained from the Department.
These regulations shall apply to high pressure steam piping system which is defined as a system operating at a steam pressure of more than fifteen (15) psi. In the application of these rules and regulations, loops, bends or offsets of the piping shall not be considered expansion joints.
   (a)   Existing systems. The following requirements are applicable:
      (1)   All expansion joints, anchorage and guides which are presently not accessible to permit a complete visual inspection, shall be made accessible. Where the integrity of any shaft enclosure is impaired hereby, proper means shall be provided to maintain its integrity. All joints, including the joints so exposed, shall be inspected for any signs, visual or audible, or any escaping steam or condensation. Where there is evidence of such escaping steam in a bellows joint, immediate appropriate action shall be taken including expeditious replacement of the joint. If the escaping steam is immediately adjacent to a tenanted area, the occupants of this area shall be evacuated and shall not be permitted to return until the joint has been replaced or removed. In all cases, the joint shall be kept under intensive surveillance by the owner until such replacement or removal. In the event that the leak is progressive and has progressed to an extent as to present a hazard, the steam system or any part thereof serviced by the affected joint shall be shut down and the Department of Buildings shall be notified immediately. The Commissioner may waive the requirement for the exposure of the structural attachments to the building of the anchorage or guides upon the certification of a professional engineer to the effect that the exposure would impair a structural element of the building and specifying the basis on which he predicates his conclusion as to the adequacy of the structural attachments to the buildings of the anchorage or guides without such exposure.  Upon exposure and initial inspection of the joints, the Commissioner shall be notified in writing by registered or certified mail. Such notification shall specify the type and location of the joints and the date inspected. The notification shall also contain the name of the person responsible for seeing that the inspections are made and properly recorded. Such inspections and exposure shall be made within two weeks from the effective date of this requirement. The initial inspection of the anchorage and guides shall be made within two months from the effective date of this requirement.  The Commissioner shall be notified in the same manner described above of any subsequent change of the person responsible for seeing that the inspections are made and records kept.  The notifications required in this paragraph shall be addressed to the Borough Superintendent of the Borough in which the system is located.
      (2)   Maintenance inspections.
         (i)   Expansion joints shall be inspected weekly.
         (ii)   The anchorage and guides shall be inspected annually. Exposure of the structural attachments to the buildings of the anchorages or guides shall not be required where the inspection reveals no improper movement or defects in the system.
         (iii)   A record of such inspections shall be kept by the person in charge of the mechanical equipment of the building or other qualified person designated by the owner and acceptable to the Commissioner. The records shall be available at the premises and subject to inspection by the Commissioner.
      (3)   No joint, anchorage or guides shall be repaired, replaced or relocated, unless and until an application has been filed and the approval of the Department is obtained. The application shall contain all pertinent information and shall be filed by a licensed professional engineer, knowledgeable as to high pressure steam piping systems. He shall be responsible for the controlled inspection of the proposed work in accordance with the approval of the Department. This provision shall not apply to tthe repacking of a slip or ball joint, however, records of such repacking shall be kept in the inspection records as hereinabove provided. When, in the opinion of the professional engineer, the requirement for prior approval by the Department of Buildings would create an imminent health or safety hazard, the professional engineer may permit the work to proceed without prior approval. In such cases, he shall, prior to the repair, replacement or relocation, notify by telephone the Borough Superintendent of the borough in which the building is located; and, if the emergency occurs at other than normal working hours, he shall notify the Emergency Section by telephone at 312-8298. This shall be followed up by the filing of the application and obtaining the approval specified above.
      (4)   The Commissioner, where he deems it necessary, shall require the replacement or relocation of any joints, guides or anchors. The Commissioner shall cause the joints in potentially hazardous locations such as those which are located adjacent to tenant occupied spaces to be relocated, unless means exist or are provided for eliminating the hazard.
      (5)   Applicability upon completion of new high pressure Steam piping systems. Upon the completion of a new high pressure steam piping system and the approval of same by the Department, the rules relating to existing high pressure steam piping systems affecting maintenance requirements and the keeping of records shall apply.
   (b)   New systems. For the purpose of the application of these rules and regulations, the replacement of existing steam piping systems, the installation of a new system in existing buildings, as well as installations in buildings hereafter constructed, shall be considered to be new high pressure steam piping systems.
