The earliest officialNFPA st
31、andard on this subject was adopted in 1921. Revised editions were adopted by theassociation in 1926, 1928, 1929, 1930, 1931, 1932, 1936, 1938, 1942, 1945, 1950, 1953, 1955,1956, 1957, 1958, 1959, 1961, 1962, 1963, 1965, 1966, 1967, 1968, 1969, 1970, 1972, 1973,1974, 1975, 1978, and 1981. In 1965, th
32、e previous editions were divided into two separatetexts, one covering installation and the second covering maintenance and use. The 1974edition recombined all the information previously contained in NFPA 10 and NFPA 10A. Anew appendix was added to the 1974 edition to include information about the se
33、lection offire extinguishers for home hazards. Information on selection and distribution of fire extin-guishers was added to the appendix of the 1978 edition. Major revisions to provide simplifi-cation and uniformity were made in the 1984 edition. The standard was revised in 1988, 1990,and 1994.In 1
34、998, NFPA 10R, Recommended Practice for Portable Fire Extinguishing Equipment in FamilyDwelling Units and Living Units, was withdrawn.

35、 edition of this standard included changes to comply with the Manual of Style forNFPA Technical Committee Documents by removing unenforceable terms.

36、ss Class D extinguishingagents and the phase-out of listed halon extinguishers. The definition of halocarbons hasbeen expanded to permit the use of any halocarbon agent acceptable under the U.S. EPASignificant New Alternatives Policy program. The list of NFPA documents that contain addi-tional requi
37、rements that supersede those found in this standard was significantly expandedfor easy reference. New travel distances for obstacle, gravity/three-dimensional, and pressurefire hazards have been added. Chapter 7, Inspection, Maintenance, and Recharging, andAnnex E, Distribution, have been significan
38、tly revised and restructured.
