35、rd on September 3,2014.Origin and Development of NFPA 101The Life Safety Code had its origin in the work of the Committee on Safety to Life of theNational Fire Protection Association, which was appointed in 1913. In 1912, a pamphlet titledExit Drills in Factories, Schools, Department Stores and Thea
36、ters was published following its presen-tation by the late Committee member R. H. Newbern at the 1911 Annual Meeting of theAssociation. Although the pamphlets publication antedated the organization of the Commit-tee, it was considered a Committee publication.For the first few years of its existence,
37、 the Committee on Safety to Life devoted its attention toa study of the notable fires involving loss of life and to analyzing the causes of this loss of life. Thiswork led to the preparation of standards for the construction of stairways, fire escapes, and otheregress routes for fire drills in vario
38、us occupancies, and for the construction and arrangement ofexit facilities for factories, schools, and other occupancies. These reports were adopted by theNational Fire Protection Association and published in pamphlet form as Outside Stairs for Fire Exits(1916) and Safeguarding Factory Workers from
39、Fire (1918). These pamphlets served as a groundworkfor the present Code. These pamphlets were widely circulated and put into general use.In 1921, the Committee on Safety to Life was enlarged to include representatives of certaininterested groups not previously participating in the standards developm
40、ent. The Commit-tee then began to further develop and integrate previous Committee publications to providea comprehensive guide to exits and related features of life safety from fire in all classes ofoccupancy. Known as the Building Exits Code, various drafts were published, circulated, anddiscussed
41、 over a period of years, and the first edition of the Building Exits Code was publishedby the National Fire Protection Association in 1927. Thereafter, the Committee continued itsdeliberations, adding new material on features not originally covered and revising variousdetails in the light of fire ex
42、perience and practical experience in the use of the Code. Neweditions were published in 1929, 1934, 1936, 1938, 1939, 1942, and 1946 to incorporate theamendments adopted by the National Fire Protection Association.1011101, Life Safety Code, NFPA, and National Fire Protection Association are register

Public attention to exit m
44、atters wasfurther stimulated by the series of hotel fires in 1946 (LaSalle, Chicago 61 dead; Canfield, Dubuque 19 dead; andWinecoff, Atlanta 119 dead). The Building Exits Code, thereafter, was used to an increasing extent for regulatorypurposes. However, the Code was not written in language suitable
45、 for adoption into law, because it had been drafted asa reference document and contained advisory provisions that were useful to building designers but inappropriate forlegal use. This led to a decision by the Committee to re-edit the entire Code, limiting the body of the text to require-ments suita
46、ble for mandatory application and placing advisory and explanatory material in notes. The re-editingexpanded Code provisions to cover additional occupancies and building features to produce a complete document.The Code expansion was carried on concurrently with development of the 1948, 1949, 1951, a
47、nd 1952 editions. Theresults were incorporated into the 1956 edition and further refined in subsequent editions dated 1957, 1958, 1959,1960, 1961, and 1963.In 1955, NFPA 101B, on nursing homes, and NFPA 101C, on interior finish, were published. NFPA 101C was revisedin 1956. These publications have s
48、ince been withdrawn.In 1963, the Committee on Safety to Life was restructured to represent all interested factions and to include onlythose members with broad knowledge of fire matters. The Committee served as a review and correlating committee forseven sectional committees whose personnel included
49、members having a special knowledge and interest in variousportions of the Code.Under the revised structure, the sectional committees, through the Committee on Safety to Life, prepared the 1966edition of the Code, which was a complete revision of the 1963 edition. The Code title was changed from Building ExitsCode to Code for Safety to Life from Fire in Buildings and Structures. The Code text was written in enforceable “code lan-guage,” and all explanatory notes were placed in an appendix.The Code was placed on a 3-year revision schedule, with new editions adopted i
