Standard on Airport Terminal Buildings, Fueling Ramp Drainage, and Loading Walkways

1.1 Scope. This standard specifes the minimum fre protection requirements for the construction and protection of airport terminal buildings. It specifes the minimum requirements for the design and maintenance of the drainage system of an aircraft fueling ramp to control the fow of fuel that can be spilled on a ramp and to minimize the resulting possible danger. In addition, it contains the minimum requirements for the design, construction, and fre protection of aircraft loading walkways between the terminal building and aircraft.
1.2 Purpose. The purpose of this standard is to provide a reasonable degree of protection for life and property from fre at airport terminal complexes.
1.2.1 Requirements applicable to ramp drainage systems are intended to limit the fre hazard from fuel spillage in the following ways: (1) Controlling the spread of a fuel spill to limit exposure to buildings, aircraft loading walkways, concourses, or elevated structures in order to prevent the fuel’s liquid or vapors from reaching a source of ignition or accumulating within structures (2) Limiting the spread of the fuel spill over the ramp surface and preventing the transmission of vapors by the drainage system from exposing aircraft or other equipment parked or operating on the ramp 1.2.2 The purpose of this standard is also to specify minimum criteria for fre protection of aircraft loading walkways that can serve as egress routes from aircraft in the event that a fre caused by a fammable liquid spill on the airport ramp exposes the walkway and the aircraft.
1.3 Application. It is not intended that the provisions of this document be applied to facilities, equipment, structures, or installations that existed or were approved for construction or installation prior to the effective date of the document, except in those cases where it is determined by the authority having jurisdiction that the existing situation involves a distinct hazard to life or adjacent property.
