Abstract:

The car rental agencies at Phoenix Sky Harbor Airport have combined their service/filling facilities in the new terminal's parking garage. This permits customers to pick up and return their cars next to the terminal, where the cars remain close to customers. This eliminates both unnecessary rental auto traffic and the need for shuttle buses. The unconventional facility needed extra design care to make it safe. The only available space for fuel dispensing that was acceptable to the car-rental agencies was on the second floor of the new parking structure, and the six agencies required six segregated fueling islands, each with a dual dispenser. Both characteristics varied from the National Fire Prevention Code's NFPA 30A specification, which the city has adopted. We solved the emergency-exit/fire-fighter access problem by recommending two pedestrian walkways from the second floor to the adjacent overhead roadway via sliding steel bar gates. Other features include double-wall fiberglass tanks with sensors in the annular space capable of detecting leaks as small as 0.02 gal./hr.; six leak detection/inventory control systems; fire detectors that sense both infrared and ultraviolet light; switches throughout the fueling area that cut off the fuel flow to all six islands; remote fill piping and Stage I and II vapor-recovery systems.
