It shall be unlawful for any utility company to supply gas to a building, place or premises in which new meters other than replacement are required until a certificate of approval of gas installation from the department is filed with such utility company. When new gas service piping has been installed it shall be locked-off by the utility either by locking the gas service line valve or by installing a locking device on the outside gas service line valve. The lock shall not be removed until the gas meter piping (other than utility-owned) and gas distribution piping has been inspected and certified as required by the department as being ready for service.
Immediately after the gas is turned on into a new system or into a system that has been initially restored after an interruption of service, the piping system shall be tested for leakage. Where leakage is indicated, the gas supply shall be shut off until the necessary repairs have been made.
The following will be required prior to placing equipment in operation as applicable:
1. Required fire protections systems (sprinkler or standpipe) are completed, inspected and ready for service.
2. Such equipment and related gas pipings are inspected by the department or authorized inspector.
3. Associated fire suppression system is inspected and approved by the Fire Department.
