NFPA 652 Standard on fundamentals of combustible dust
The standard became effective on Sept. 7, 2015. It outlines the general requirements for controlling combustible dust hazards and refers to NFPA’s five industry- or commodity-specific standards when applicable: NFPA 61: Standard for the Prevention of Fires and Dust Explosions in Agricultural and Food Processing Facilities; NFPA 484: Standard for Combustible Metals; NFPA 654: Standard for the Prevention of Fire and Dust Explosions from the Manufacturing, Processing, and Handling of Combustible Particulate Solids; NFPA 655: Standard for the Prevention of Sulfur Fires and Explosions; and NFPA 664: Standard for the Prevention of Fires and Explosions in Wood Processing and Woodworking Facilities
NFPA 652 complements NFPA 654 by providing more specific guidelines on general dust combustibility and when to use those standards for all industries. The standard emphasizes the need for both fire protection and explosion protection to a greater degree than NFPA 654.
