32、ire safety. The first edition of NFPA 801, whose coverage was limited tolaboratories handling radioactive materials, was adopted at the 1955Annual Meeting.In 1970, the format was revised and the document was updated to reflect current thinkingand practices.The document was also expanded to apply to
33、all locations, exclusive of nuclearreactors, where radioactive materials were stored, handled, or used.The 1975 edition was a reconfirmation of the 1970 edition with editorial changes.The 1980 edition included a clarified statement regarding the presence of and levels ofradiation; cautionary stateme
34、nts about the assumption of risks by the fire officer and theimportanceoftraininginthehandlingofradioactivematerialsbyfiredepartmentpersonnel;a clarification concerning the variations of the intensity of a radiation field; and a restyling ofthe document to conform with the NFPAManual of Style.The 19
35、85 edition revised and updated previous material for clarification in recognition oftechnology and terminology changes.The 1991 edition was a total revision of the document, which included a complete reorga-nization of the chapters.
