This publication supersedes the third edition of the Institute of Petroleum's Model Code of Safe Practice Part 7 Airports Safety Code, published in 1998, and the second edition of the American Petroleum Institute's Publication 1500 Storage and Handling of Aviation Fuels at Airports, which was withdrawn in 1998. It has been prepared jointly by the API Aviation Technical Services Subcommittee and EI Aviation Committee, in consultation with other industry stakeholders, and provides guidance on the siting, layout, design, construction, operation and maintenance of aircraft fuelling facilities, including the design and construction of fuellers, hydrant servicers and ancillary equipment used in fuelling aircraft. The guidance contained in this edition has been significantly revised from earlier editions to ensure that the safe practices contained herein are equally applicable in all areas of the world; to include adequate guidance for the large number of non-airline type facilities used by retail and consumer-type operations; to include suitable reference to environmental protection controls and facilities that are receiving increased emphasis and regulation in some regions and to ensure that the guidance reflects current levels of knowledge and industry experience. Essential reading for engineering contractors, aviation fuel handling equipment suppliers, aviation fuel suppliers, hydrant operators, into-plane fuelling companies, airlines and airport authorities worldwide.
