The earliest officialNFPA st

31、andard on this subject was adopted in 1921.

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.

The list of NFPA documents that contain addi-tional requi

37、rements that supersede those found in this standard was significantly expandedfor easy reference.
