  • Description

    Help mitigate risks of fire and explosion in electric generating plants by complying with the latest recommended safety practices.

    There are special concerns for fire and life safety in plants and facilities that produce or convert the current of electricity. NFPA® 850, Recommended Practice for Fire Protection for Electric Generating Plants and High Voltage Direct Current Converter Stations, 2020 edition, is an essential resource for assisting in maximizing the safety of personnel, facilities, and the community at large. Criteria apply to new and existing oil, gas, coal, and alternative fuel electrical generating plants, including high voltage direct current converter stations and combustion turbine units used for electric generation.

    The document provides the framework for creating a Fire Protection Design Basis Document that takes into account potential risks to the particular facility, including flammable liquids, fuels, lubricating oils, dust explosions, and electrical equipment. NFPA 850 also covers the protection and continuity of installations and personnel, systems and components, and plant operations.

    The NFPA 850, 2020 edition, provides access to cutting-edge criteria for fire prevention and protection of plants generating electricity.

    Developed to provide a document specifying fire protection measures for all types of non-nuclear electric generating plants, the revised NFPA 850 reflects the most current industry knowledge and best practices.

    Significant changes to the 2020 edition include:

    • Complete reorganization of the document for accuracy and clarity
    • Grouping of information in a more logical layout to assist users in navigating the document faster and more efficiently
    • Addition of new chapters on flywheel energy systems and compressed air energy storage (CAES) to address technologies being used in the industry

    Get the support you need to help identify and reduce risks to lives and property in electrical generating plants.

    NFPA 850, Recommended Practice for Fire Protection for Electric Generating Plants and High Voltage Direct Current Converter Stations, is a must-have for facility managers, designers, installers, inspectors, and authorities having jurisdiction. Assist in avoiding downtime, damages, and loss and in increasing safety and productivity by ordering your copy of the 2020 edition.

    2015 Edition

    Reduce fire and explosion risks with the 2015 edition of NFPA 850 for fire protection in electric generating plants.

    NFPA 850, Recommended Practice for Fire Protection for Electric Generating Plants and High Voltage Direct Current Converter Stations outlines fire safety recommendations for gas, oil, coal, and alternative fuel electric generating plants including high voltage direct current converter stations and combustion turbine units used for electric generation. Provisions apply to both new and existing facilities.

    Gain confidence that your fire protection plan addresses all relevant hazards.

    NFPA 850's recommendations address the safety of construction and operating personnel, physical integrity of plant components, and the continuity of plant operations. NFPA 850 requires the development of a Fire Protection Design Basis Document that identifies relevant hazards -- such as the presence of fuels, lubricating oils, flammable liquids, electrical equipment, and dust explosions -- along with how installations will be protected.

    The expanded 2015 edition of NFPA 850 gives designers, installers, facilities managers, and inspectors a comprehensive go-to source:

    • The complete 2010 edition of NFPA 851, Hydroelectric Generating Plants has been incorporated into NFPA 850 in a stand-alone chapter.
    • Added coverage of active carbon injection systems reflects increasing use in the field. The powdered active carbon used in these types of systems could present an explosion hazard. The 2015 NFPA 850 increases awareness of the risks and offers mitigation strategies.

    Information in the 2015 NFPA 850 not only helps users provide a high-level of safety for facility personnel and the surrounding community, it also helps reduce the risk of serious equipment damage and costly unexpected downtime which could have serious economic consequences.
