30、PA 820 Standard for Fire Protection in Wastewater Treatment and Collection Facilities 2016 Edition This edition of NFPA 820, Standard for Fire Protection in Wastewater Treatment and Collection Facilities, was prepared by the Technical Committee on Wastewater Treatment Plants. It was issued by the St

31、andards Council on May 26, 2015, with an effective date of June 15, 2015, and supersedes all previous editions. This edition of NFPA 820 was approved as an American National Standard on June 15, 2015. Origin and Development of NFPA 820 The Committee on Wastewater Treatment Plants was organized in 19

32、83 to have primary responsibility for documents on safeguarding against the re and explosion hazards specic to wastewater treatment plants and associated collection systems. This document includes the hazard classication of specic areas and processes. The need to develop NFPA 820 was based on re or

33、explosion incidents that, while infrequent, are relatively severe when they do occur. Initial work on the document was begun early in 1985 and resulted in the rst edition being issued in 1990. Extensive changes were made between the rst edition and the 1992 edition, with the most notable revision be

34、ing the document title, which was changed from Recommended Practice for Fire Protection in Wastewater Treatment Plants to Recommended Practice for Fire Protection in Wastewater Treatment and Collection Facilities. In addition, the document scope was revised to include storm sewer systems and their a

35、ppurtenances. In 1995 the document was changed from a recommended practice to a standard, which contains mandatory requirements. This was done because NFPA 820 was widely referenced by various jurisdictions. The 1999 edition of NFPA 820 was changed to include some editorial corrections and to make t

36、he document more enforceable. The denitions were also modied to conform to NFPAs Manual of Style. For the 2003 edition, the entire document was reformatted to conform to the Manual of Style for NFPA Technical Committee Documents. Denitions were revised to conform to the NFPA Glossary of Terms. The 2

37、008 edition included guidance on waste gas burners and enclosed aeration basins. Denitions were coordinated with the NFPA Glossary of Terms. The 2012 edition incorporated editorial changes to Table 5.2, Table 6.2(a), and Table 6.2(b). A new denition was added for waste gas burners, along with mitiga

38、tion steps to Section 10.11 on re and explosion prevention control procedures. Ventilation requirements and supporting language were revised to provide clarity and to tie in with an effort to better coordinate with associated industry documents. For the 2016 edition, all tables have been reformatted

39、 for better readability and reviewed and revised to provide clearer guidance on when the requirements apply. Combustible gas detector requirements have been modied in several locations in the tables. Construction requirements throughout the document have been revised to indicate that building codes

40、cover general building construction; components of the wastewater facility are covered by the requirements provided in the chapter tables. The 2016 edition requires alarm signaling for combustible gas detectors and ventilation since those systems are critical in preventing res and explosions. The do

41、cument also has been revised to better indicate conditions under which dual ventilation can be used.FIRE PROTECTION IN WASTEWATER TREATMENT AND COLLECTION FACILITIES 820-2 2016 Edition Technical Committee on Wastewater Treatment Plants Glenn E.
