Understanding NFPA 660 | Just Venting

In industries where combustible dust is present, ensuring workplace safety is paramount. The National Fire Protection Association (NFPA) has taken a significant step forward in simplifying and consolidating safety regulations with the introduction of NFPA 660. This new standard represents a unified approach to combustible dust safety, merging multiple existing standards into a single, comprehensive document. But what does this mean for your business, and how can you stay compliant? Let’s take a closer look.

What is NFPA 660?

NFPA 660 is a new standard designed to consolidate and replace several existing NFPA combustible dust standards, including:

• NFPA 61: Agricultural and Food Processing Facilities
• NFPA 484: Standard for Combustible Metals
• NFPA 652: Fundamentals of Combustible Dust
• NFPA 654: General Industry Dust Handling and Processing
• NFPA 655: Sulfur Fires and Explosions
• NFPA 664: Wood Processing and Woodworking Facilities

By bringing these standards together, NFPA 660 aims to simplify compliance, reduce confusion, and create a more streamlined approach to managing combustible dust hazards across various industries.

Key Changes and Updates

With the introduction of NFPA 660, businesses need to be aware of some critical changes, including:

1. Unified Requirements: Rather than navigating multiple documents, facilities will now reference a single standard, making it easier to ensure compliance.
2. Risk-Based Approach: NFPA 660 emphasizes a performance-based approach, allowing facilities to tailor their safety measures based on specific risks.
3. Dust Hazard Analysis (DHA) Requirements: The standard maintains the requirement for DHAs but refines the process to align with a more unified framework.
4. Improved Clarity: The consolidation removes redundancies and provides clearer guidance on how to assess and mitigate combustible dust hazards.
5. Industry-Specific Chapters: While NFPA 660 provides overarching safety requirements, it also includes industry-specific provisions to address unique risks.

Structure of NFPA 660

The standard is organized into chapters that cover both general and industry-specific requirements for combustible materials:

• Chapters 1-9: These initial chapters update and expand upon the fundamentals previously outlined in NFPA 652. They address topics such as:
  • Scope, purpose, and application of the standard.
  • Definitions and terminology.
  • General requirements for managing combustible dust hazards.
  • Hazard identification and risk assessment methodologies.
  • Dust Hazard Analysis (DHA) procedures.
  • Management systems and organizational responsibilities.
  • Hazard prevention and mitigation strategies.
• Chapters 10-15: These chapters incorporate industry-specific guidelines from the previously separate standards, providing tailored requirements for:
• Annexes: The annexes offer supplementary information, including:
  • Examples of Dust Hazard Analyses.
  • Guidance on material characterization and testing.
  • Details on fire and explosion protection measures.
  • Methods for isolation and prevention of deflagration propagation.

Implications for Industries

The introduction of NFPA 660 has several implications for industries handling combustible dust or combustible solids:

1. Simplified Compliance: With all relevant guidelines consolidated into a single document, facilities can more easily identify and implement the necessary safety measures.
2. Consistency Across Operations: The unified standard promotes a consistent approach to hazard management, reducing the potential for discrepancies in safety practices across different facilities or sectors.
3. Regulatory Alignment: While NFPA standards are not laws, they are often referenced by regulatory bodies such as the Occupational Safety and Health Administration (OSHA). Adhering to NFPA 660 can help facilities demonstrate compliance with safety regulations and industry best practices.

Proactive Hazard Management: The emphasis on regular Dust Hazard Analyses and updated management systems encourages facilities to adopt a proactive stance in identifying and mitigating risks, thereby enhancing overall safety.

Why Compliance Matters

Failure to comply with NFPA 660 can result in serious consequences, including workplace accidents, regulatory fines, and legal liabilities. Combustible dust incidents have led to devastating explosions, injuries, and even fatalities in the past. By staying compliant, businesses can enhance safety, protect their workforce, and avoid costly penalties.

Steps to Prepare for NFPA 660

To ensure compliance with NFPA 660, consider the following steps:

• Review the Standard: Familiarize yourself with NFPA 660 and understand how it applies to your facility.
• Conduct a Dust Hazard Analysis (DHA): If you haven’t already, perform a DHA to identify and mitigate potential hazards.
• Update Safety Procedures: Adjust your safety protocols and training programs to align with the new standard.
• Invest in Proper Equipment: Ensure you have the right dust collection, ventilation, and housekeeping systems in place.
• Work with Experts: Consulting with combustible dust safety professionals can help streamline compliance and enhance workplace safety.
• Consult with an industrial vacuum specialist to create a dust collection system for your facility.

The Bottom Line

NFPA 660 marks a significant shift in how combustible dust safety is regulated. By consolidating multiple standards, the NFPA has created a clearer, more efficient framework for industries handling combustible dust. Now is the time for businesses to familiarize themselves with the new requirements, update their safety programs, and take proactive steps to protect their operations and employees.

One of the most important and effective ways to ensure that facilities are safe is to provide routine housekeeping, which includes cleaning methods, frequency and types of equipment used. Not just any vacuum can be used. Goodway offers a complete line of vacuums designed to work with many different types of combustible dust and in different classified environments. Each application and each area of the facility could require a different solution or level of protection.

Solutions may include:

It’s important to consult with experts that are well versed in the safety requirements, and can provide equipment that can vacuum the specific material, amounts of material and filter the material to create a long lasting solution. From portable to multi-user regional vacuum systems with specialized attachments to clean high reach and hard to reach overhead areas.
