NFPA 654-2020 PDF Download

The NFPA 654-2020 standard is a comprehensive guide for managing fire and explosion hazards related to combustible particulate solids and hybrid mixtures. It is an important resource recognized by OSHA's Combustible Dust National Emphasis Program (NEP) to identify dust hazards and define mitigation strategies.

The standard covers various aspects of safety practices, including 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. It also provides guidance on the application of area electrical classification for different levels of dust accumulation.

NFPA 654-2020 has undergone a significant reorganization to align with NFPA 652, the "Standard on the Fundamentals of Combustible Dust." This restructuring involves moving existing requirements and clarifying retroactive code requirements. New provisions have been added to address hazards associated with ultrafine particles and additive manufacturing. Additionally, requirements for static, conductivity, and portable vacuum cleaners have been extracted from NFPA 652 and incorporated into NFPA 654-2020.

This standard is crucial for facility owners/operators, engineers, enforcers, insurance professionals, equipment manufacturers, and testing and research facilities involved in the storage, handling, or use of combustible particulate solids. It provides up-to-date protocols and measures to effectively identify dust hazards and establish control measures to mitigate fire and dust explosion risks.
