For the purpose of this chapter, certain terms shall be defined as follows:
A. DOWNSTREAM OF GAS UTILITY METER. Shall refer to all customer owned gas piping.
B. RESIDENTIAL BUILDING. Shall mean any single-family dwelling, duplex, multifamily dwelling, apartment building, condominium building, townhouse building, lodging house, congregate residence, hotel, or motel.
C. EXCESS FLOW GAS SHUT-OFF DEVICE. Shall mean those values or devices that are not actuated by motion, but are activated by significant gas leaks or overpressure surges, which can occur when pipes rupture inside the structure. The design of the device shall provide a proven method to provide automatically for expedient and safe gas shutoff in an emergency. The design of the device shall provide a capability for ease of consumer or owner resetting in a safe manner. The device shall be certified by the state architect or the operational and functional design of the device shall meet or exceed the device certified by the office of the state architect. The determination of whether the operational and functional design of the device is at least equal to the device certified by the state architect may be made by one of the following: the Independent Laboratory of the International Approval Services (IAS), Underwriter's Laboratory (UL), International Association of Plumbing and Mechanical Officials (IAPMO), or other recognized listing and testing agency.
D. SEISMIC GAS SHUT-OFF DEVICE. Shall mean a system consisting of a seismic sensing means and actuating means designed to actuate automatically a companion gas shut off means installed in a gas piping system in order to shut off the gas downstream of the location of the gas shutoff means in the event of a severe seismic disturbance. The system may consist of separable components or may incorporate all functions in a single body. The device shall be certified by the state architect and the operational and functional design of the device shall meet or exceed the device certified by the office of the state architect. The determination of whether the operational and functional design of the device is at least equal
to the device certified by the state architect may be made by one of the following: the Independent Laboratory of the International Approval Services (IAS), Underwriter's Laboratory (UL), International Association of Plumbing and Mechanical Officials (IAPMO) or other recognized listing and testing agency.
E. UPSTREAM OF GAS UTILITY METER. Shall refer to all gas piping installed by the utility up to and including the meter and the utility's bypass tee at the connection to the customer owned piping.
F. GAS SHUT-OFF DEVICE. As used in this chapter, shall refer to either a seismic gas shutoff device or excess flow gas shut-off device. (Ord. 01-101 § 2(part), 2001).
