  • Description

    The 2017 edition of NFPA 654 provides a comprehensive approach to managing fire and explosion hazards involving combustible particulate solids and hybrid mixtures.

    Tragic experiences in the United Stated attest to the need for detailed regulations on dust hazard mitigation. NFPA 654: Standard for the Prevention of Fire and Dust Explosions from the Manufacturing, Processing, and Handling of Combustible Particulate Solids is referenced by OSHA's Combustible Dust National Emphasis Program (NEP) for the purposes of identifying dust hazards and defining mitigation strategies that protect life and property.

    The 2017 edition of NFPA 654 presents the latest protocols.

    The 2017 edition of the Standard provides fundamental, industry-recognized safety practices for facility and systems design, process equipment protection, fugitive dust control and housekeeping, ignition source identification and control, fire protection, training and procedures, inspection, and maintenance. Although the requirement to perform a hazard analysis has been part of the Standard since the 2006 edition, this 2017 edition of NFPA 654 includes requirements to perform a dust hazard analysis (DHA) retroactively for facilities constructed prior to the 2006 edition.

    The 2017 edition of NFPA 654 works with first-time NFPA 652, to help users identify dust hazards and establish the most effective control measures for the hazard and the type of facility.

    This 2017 edition of NFPA 654 contains changes that help align the Standard with the 2016 edition NFPA 652: Fundamentals of Combustible Dust -- the industry's first Standard with general provisions for managing dust hazards. Definitions in new NFPA 654 are aligned with those in NFPA 652, and the objectives in Chapter 4 have been updated.

    NFPA 654 is essential for owner/operators of facilities that store, handle, or use combustible particulate solids; along with insurance professionals, design engineers, fire protection engineers, equipment manufacturers and vendors, enforcers, and testing laboratories or research facilities. Annexes include guidance on the application of area electrical classification for various dust accumulation levels. (Softbound, 44 pp., 2017)
