The National Fire Protection Agency (NFPA) is in the process of creating a new standard, NFPA 660 Standard for Combustible Dusts, that will combine all existing combustible dust standards. NFPA 660 standard for combustible dust will provide industry-specific standards for managing combustible dusts, prevention of fire, and promoting best practices to safeguard facilities from related fires and dust explosions.
NFPA 660 is in the Fall 2024 cycle due to the Combustible Dust Document Consolidation Plan approved by the NFPA Standards Council. As part of process, the NFPA 660 combustible dust standard will be all encompassing and combines the NFPA Standards NFPA 61, NFPA 484, NFPA 652, NFPA 654 (with sulfur fires), NFPA 655, and NFPA 664.

All In One Source, for Standards
The new NFPA, one combustible dust standard will incorporate the following existing NFPA standards that outline how to manage and prevention of fire and dust hazards:
NFPA 484: Standard for Combustible Metals
NFPA 652: Standard Fundamental of Combustible Dust
NFPA 655: Standard for Prevention of Sulfur Fires and Explosions
NFPA 660: Revolutionizing Combustible Dust Safety Standards
In industrial settings where dust accumulates in dust collection systems, and combustible dusts particles linger in the air, the risk of fires and dust explosions is a looming threat. These combustible dust hazards pose significant challenges for safety professionals and facility managers, necessitating robust standards and guidelines to mitigate potential dust explosions and risks. Recognizing this imperative, the National Fire Protection Association (NFPA) is considering introducing the new standard, a groundbreaking, all encompassing standard with existing standards, specifically tailored to address a combustible dust hazard.

Scheduled for release in the Fall 2024 cycle, this new combustible dust standard is poised to revolutionize the landscape of combustible dusts safety standards, and as a standard for the prevention of future dust explosions. By combining critical guidelines from existing standards, the new NFPA standard aims to provide a comprehensive framework, with the fundamentals of combustible dust, and increase minimum requirements, for managing combustible dusts hazards across diverse industrial sectors.
Understanding the Need for the new NFPA 660 Standard
The need for a specialized standard like NFPA 660 stems from the inherent risks associated with combustible dusts. When fine particles of combustible materials accumulate in dust collection systems and in the air, they can ignite and lead to devastating fires and explosions. Industries such as agriculture, food processing facilities, metalworking, coal processing, wood processing, woodworking facilities, additive manufacturing, 3D printing, and chemical processing are particularly susceptible to combustible dust hazards with combustible metals accumulating inside a dust collection system. A dust collection system and dust collectors, may require extra attention for a root cause analysis, with dust accumulation. The wood processing, agriculture industry and combustible metals industry are especially prone to a dust explosion hazard. Combustible metals, wood dust in woodworking facilities, and dry goods in dust collection systems within these industries, continue to be problematic. The new standard would be a significant change for combustible metals nfpa and associated combustible dusts involved.
Historically, addressing combustible dust hazards has been challenging due to the lack of specific guidelines and combustible dust NFPA standards, and commodity specific standards. Existing NFPA combustible dust standards, including the NFPA Standards: NFPA 61, NFPA 484, NFPA 652, NFPA 654, NFPA 655 (with sulfur fires), and NFPA 664, each focus on specific aspects of combustible dusts safety. NFPA 664 (Standard for the Prevention of Fire and Dust Explosions from the Manufacturing, Processing, and Handling of Combustible Particulate Solids) has been picked up largely unchanged in Chapter 13 of NFPA 660 standard for combustible dusts. NFPA 654 Standard for the Prevention of Fire and Dust Explosions from the Manufacturing, Processing, and Handling of Combustible Particulate Solids, will allow for the base in understanding the new standard. However, the absence of a consolidated, all encompassing standard has led to inconsistencies in safety protocols and hazard management across industries.
The Creation of the NFPA 660 Standard
The new combustible dust standard emerges as a response to the pressing need for a unified approach to dust safety. The Combustible Dust Document Consolidation Plan, approved by the NFPA Standards Council, lays the groundwork for the development of NFPA 660. This plan integrates key combustible dust existing standards, streamlining guidelines, commodity specific standards and best practices into a single, comprehensive document.
By consolidating combustible dust standards such as NFPA 61, which focuses on agricultural and feed processing facilities, and the existing combustible dust NFPA standards of NFPA 654 and NFPA 652, which addresses manufacturing and handling of combustible particulate solids. The NFPA 660 ensures that industries have access to relevant and practical guidance tailored to their specific operations, and increase minimum requirements for safety.
Key Components of the new NFPA 660 Standard
The new standard NFPA 660 encompasses a wide array of topics and guidelines to effectively manage dust hazards. Some of the key components of the new standard NFPA 660 include:
- Risk Assessment and Hazard Identification: the new standard NFPA 660 provides methodologies for conducting a thorough dust hazard analysis and risk assessments and identifying potential dust hazards within industrial facilities.
- Preventive Measures and Controls: The standard outlines preventive measures and engineering controls, such as a dust collection system, to mitigate the risk of dust accumulation, ignition sources, and potential ignition sources.
- Housekeeping and Maintenance Practices: NFPA 660 emphasizes the importance of regular housekeeping and maintenance practices to minimize the accumulation of dust, including a dust collection system, and ensure the proper functioning of safety systems.
- Training and Education: The standard underscores the importance of comprehensive training and education programs for personnel involved in handling, processing, and managing combustible materials.
- Emergency Response and Preparedness: NFPA 660 provides guidelines for developing emergency response plans and procedures to effectively mitigate the impact of fires and explosions caused by dust incidents.
By addressing these critical components, NFPA 660 combines combustible dust standards, equips industries with the tools and knowledge needed to create safer work environments, and minimize the risk of dust related incidents.
Implications for Industry Professionals
The introduction of NFPA 660 carries significant implications for industry professionals involved in safety management, facility operations, and regulatory compliance. As NFPA 660 becomes the benchmark for dust safety standards, professionals must familiarize themselves with its provisions, and additional information, and integrate them into their safety protocols and practices.
Furthermore, compliance with NFPA 660 not only enhances workplace safety but also helps organizations mitigate potential liabilities associated with dust hazards. By adhering to the guidelines outlined in NFPA 660, industries can demonstrate their commitment to safety, with fundamentals of combustible dust, and minimize the risk of costly fines, litigation, and reputational damage resulting from preventable secondary explosions.
Looking Ahead: Implementation and Adoption
As the release of proposed standard NFPA 660 draws near, industry stakeholders must prepare for its implementation and adoption, after the final review. Training programs, educational resources, and outreach initiatives can help disseminate additional information about NFPA 660 and facilitate its integration into existing safety management systems.
Moreover, collaboration among industry associations, regulatory agencies, and stakeholders will be instrumental in promoting the widespread adoption of NFPA 660 and driving continuous improvement in dust safety practices.
