NFPA 654 - Standard for the Prevention of Fire and Dust Explosions from the Manufacturing, Processing, and Handling of Combustible Particulate Solids, 2006 Edition

This Standard provides critical requirements that ensure safety to life and property from fire and explosion associated with the manufacturing, processing, blending, pneumatic conveying, repackaging and handling of combustible particulate solids or hybrid mixtures. These up-to-date rules serve to maximize safety. The document has also been revised to improve consistency, usability, and readability. Approx. 34 pp.

The 2006 edition incorporates the following changes:

•  Revised the definition of combustible dust, deflagration, and hybrid mixture.
• Revised and expanded provisions applicable to intermediate bulk containers (IBCs) to bring the requirements up to the current state-of-the-art in IBC technology.
  
• New performance-based requirements (revised Chapter 4 and new Chapter 5) provide flexibility in applying the Standard.
  
• New Annex material provides expanded guidance on the application of area electrical classification for various dust accumulation levels and safeguards.
