Title:	NFPA 660: What you should know.
Authors:	Murphy, Michelle¹ (AUTHOR) murphy@micadhm.com, Cloney, Chris² (AUTHOR), Kreitman, Kevin L.³ (AUTHOR)

Subjects:	National Fire Protection Association, Safety standards, Bulk solids, Industrial safety, Dust control, Fire prevention, Regulatory compliance
Abstract:	NFPA 660, Standard for Combustible Dusts and Particulate Solids, became effective on December 6, 2024. This standard is the product of an effort, extending over a decade, to make the National Fire Protection Association (NFPA) requirements for the safe handling of combustible dust, easier for the user to understand and apply. This effort began in March 2011 and was complete in the fall of 2024, with the publishing of NFPA 660. The result, NFPA 660, is organized into chapters establishing requirements fundamental to all combustible dusts, followed by individual chapters providing additional requirements specific to each industry or commodity. In this article, the authors draw on their experiences working on multiple NFPA committees, conversations with committee members, and reviews of the NFPA 660 with multiple stakeholders, to describe the organization of the standard, provide a high‐level summary of the requirements, and share major updates and changes from previous combustible dust standards. Readers will gain an understanding of the requirements, learn what changes will need to be made to existing programs already in compliance with previous standards, and know how to navigate the standard to find the information they need to ensure safe operation of facilities processing and handling combustible dusts.
