NFPA 1931 Standardfor ManufacturersDesignofFireDepartmentGroundLadders 2015Edition This edition of NFPA 1931, Standard for Manufact

30、urers Design of Fire Department Ground Ladders, was prepared by the Technical Committee on Fire Department Ground Ladders. It was issued by the Standards Council on July 14, 2014, with an effective date of July 29, 2014, and supersedes all previous editions. This edition of NFPA 1931 was approved as

31、 an American National Standard on July 29, 2014. OriginandDevelopmentofNFPA1931 In 1959, new material was added to NFPA 193,FireDepartmentLaddersGroundandAerial, covering requirements for the construction of ground ladders while continuing to cover their use, maintenance, and testing. These requirem

32、ents recognized aluminum as a product for the construction of fire department ground ladders. In May 1972, a complete revision of the 1959 edition of NFPA 193 was adopted. In 1975, NFPA 193 was separated into two documents, NFPA 1931, Standard on Fire Depart- mentGroundLadders, and NFPA 1904,Recomme

33、ndedPracticefortheMaintenance,Care,Testingand Use of Fire DepartmentAerial Ladders and Elevating Platforms. The 1979 edition incorporated extensive revisions, including editorial and style changes. In 1984, the text of NFPA 1931 was again divided into two documents. NFPA 1931 con- tained the require

34、ments for manufacturers on design and design verification testing for new ground ladders. A companion document, NFPA 1932,StandardonUse,Maintenance,andService Testing of Fire Department Ground Ladders, covered requirements for the ground ladder user. The 1984 revision increased the requirements for

35、the strength of the ladder as well as dimen- sional requirements. The 1989 edition included additional requirements for labels, modified requirements for rung spacing, added requirements for securing halyards, and required staypoles to be stow- able against the base section if they could not be prop

36、erly deployed. The 1994 edition added a table of ladder duty ratings, added additional requirements for wood ground ladders, and modified some of the labeling requirements. The 1999 edition basically editorially revised and updated the standard to keep it current. This 2004 edition changed the title

37、 of the document toStandardforManufacturersDesignof Fire Department Ground Ladders and revised the scope and purpose statements to emphasize that the document is for the ground ladder manufacturer, not the end user. The entire document was revised into the current NFPAManual of Style and updated to

38、clarify vague or ambiguous language in the standard. The 2010 edition of this standard included multi-purpose ladders. NFPA 1901,Standardfor Automotive FireApparatus, recognized the installation of multi-purpose ladders in lieu of fold- ing ladders on apparatus. As such, a statement of construction

39、specification was necessary to ensure a minimum duty rating ladder is employed. The 2015 edition of NFPA 1931 sees little change from previous editions. The Technical Committee recognized its mature development and made only minor adjustments to manda- tory language. 19311 NFPA and National Fire Pro
