30、Association . All Rights Reserved. NFPA 418 Standard for Heliports 2016 Edition This edition of NFPA 418, Standard for Heliports, was prepared by the Committee on Helicopter Facilities. It was issued by the Standards Council on November 14, 2015, with an effective date of December 4, 2015, and super
31、sedes all previous editions. This edition of NFPA 418 was approved as an American National Standard on December 4, 2015. Origin and Development of NFPA 418 The development of NFPA 418 began in 1965 after the NFPA Sectional Committee on Aircraft Hangars and Airport Facilities was asked to provide gui
32、dance on the construction and protection of elevated heliports. Earlier work had been done by the NFPA Sectional Committee on Aircraft Rescue and Fire Fighting with regard to re protection in the event of accidents during ight operations, and the NFPA Sectional Committee on Aircraft Fuel Servicing d
33、eveloped the safeguards needed for the prevention of re accidents during fueling operations at such locations. In 1967, a Tentative Standard on Elevated Heliport Construction and Protection was approved at the NFPA Annual Meeting. The 1968 edition was a revision of the tentative standard, including
34、a change in title, and the 1973 edition was a complete revision of the 1968 edition. The 1979 edition contained further amendments. The 1990 edition added chapters for land-based facilities and offshore heliports, and the title was changed from Standard on Rooftop Heliport Construction and Protectio
35、n to Standard for Heliports. The standard was revised for the 1995 edition, and criteria for rooftop helicopter hangars were added for the 2001 edition. The 2006 edition was a partial revision. The 2011 edition revised the requirements for means of egress, fuel equipment locations, and suppression s
36、ystem design and testing, and a requirement for emergency response planning was added. Those changes were intended to address problems that had contributed to recent helipad res. For the 2016 edition, the committee wanted to build on the improvements in the previous edition. This edition adds a retr
37、oactivity clause to provide a means for ensuring the safety of existing heliports without requiring full compliance. New criteria for determining noncombustibility of helipad materials have been incorporated. The authority having jurisdiction is required to approve the emergency response plan, to en
38、sure that the plan is coordinated with rst responders. The committee has also reorganized the section on re protection for rooftop heliports for clarity while also addressing the following technical issues: (1) The foam discharge duration is increased from 5 minutes to 10 minutes to better align wit
39、h other standards and to allow additional time for rst responders to reach the rooftop heliport. (2) Signs to identify the foam system activation stations are now required to ensure that personnel are able to locate and identify the correct pull station in an emergency. (3) The foam system shutoff c
40、ontrols are required to be located where they will be accessible during a re on the helipad. The committee also assigned a task group to further study the implications of requiring compliance with the latest edition of FAA AC 150/5390. A second task group was assigned to review the requirements for
41、portable extinguishers. Following the task group reports, the committee reafrmed the existing requirements.HELIPORTS 418-2 2016 Edition Technical Committee on Helicopter Facilities Raymond A.
