Testing, inspection, and maintenance should be documented with written procedures, results, and followup corrective actions recorded and tracked for closure. Impairments. A written procedure should be established to address impairments to fire protection systems and other plant systems that impact the level of fire hazard (., dust collection systems, HVAC systems). As a minimum this procedure should address the following: (1) Identify equipment not available for service (2) Identify personnel to be notified (., plant fire brigade leader, public fire 中國(guó)最龐大的資料庫(kù)下載 Copyright NFPA 中國(guó)最龐大的資料庫(kù)下載 department, plant fire protection coordinator, control room operator, etc.) (3) Increase fire surveillance as needed [see 23(f)] (4) Provide additional protected measures as necessary (., temporary water supplies, additional hose, etc.) Table Reference Guide for Fire Equipment Inspection, Testing, and Maintenance Item NFPA Document No. Supervisory and Fire Alarm Circuits 72 Fire Detectors 72 Manual Fire Alarms 72 Sprinkler Water Flow Alarms 25/72 Sprinkler and Water Spray Systems 25/72 Foam Systems 11A/16/25 Halogenated Agent, Chemical and CO2 Systems 12/12A/17/20xx Fire Pumps and Booster Pumps 25/72 Water Tanks and Alarms 25/72 and . amp。F (176。S), CA [SE] (Alt. to H.

It was issued by the Standards Council on January 14, 20xx, with an effective date of February 11, 20xx, and supersedes all previous editions. This edition of NFPA 850 was approved as an American National Standard on February 11, 20xx. Origin and Development of NFPA 850 The Committee on NonNuclear Power Generating Plants was anized in 1979 to have primary responsibility for documents on fire protection for nonnuclear electric generating plants. Begun early in 1980, the first edition of NFPA 850 was officially released in 1986 as the Remended Practice for Fire Protection for Fossil Fueled Steam Electric Generating Plants. The second edition of NFPA 850 was issued in 1990 under the revised title of Remended Practice for Fire Protection for Fossil Fueled Steam and Combustion Turbine Electric Generating Plants. This second edition incorporated a new Chapter 6 on the identification and protection of hazards for bustion turbines. In 1991 the mittee changed its name to the Technical Committee on Electric Generating Plants. This simplified name was made to reflect the mittee’s scope to cover all types of electric generating plants except nuclear. The 1992 edition of NFPA 850 incorporated a new Chapter 7 on alternative fuel electric generating plants. As part of these changes, the document title was revised to the Remended Practice for Fire Protection for Electric Generating Plants. Various other technical and editorial changes were also made. The 1996 edition of the standard added a new Chapter 8 on fire protection for high voltage direct current (HVDC) converter stations. In addition, the title was changed to Remended Practice for Fire Protection for Electric Generating Pla
