Combustible Dust - How Concerned Should You Be?
Did you know that combustible dust is a leading cause of industrial fires and explosions, costing businesses billions annually? These fine particles, accumulating on surfaces and in the air, pose severe risks to operations and safety. Beyond threatening lives and infrastructure, dust infiltration can clog machinery, accelerate wear, and drive-up maintenance costs. Frequent downtime for cleaning and repairs further disrupts production and impacts profitability. To safeguard employees and ensure operational continuity, businesses must prioritize effective dust management, routine maintenance, and strict adherence to NFPA standards.

What is the NFPA?
The National Fire Protection Association (NFPA) is the leading organization for dust management and safety. Its standards are vital for protecting industrial workers and their environments. To address combustible dust hazards, the NFPA has established a series of requirements to minimize risks. Among these, the NFPA recommends maintaining dust concentrations below the Minimum Explosible Concentration (MEC) — the threshold at which dust suspended in air can ignite and explode. Furthermore, NFPA mandates that combustible dust should not accumulate in work areas or HVAC systems. Regular maintenance, including filter replacement and post-production clean-up, is essential.
Transition to NFPA 660: A Unified Standard
The NFPA has consolidated six combustible dust standards into a single, comprehensive standard: NFPA 660. This new standard, titled 'Standard for Combustible Dusts and Particulate Solids,' was officially released in 2024 and supersedes the previous standards NFPA 61, 484, 652, 654, 655, and 664. This unified approach aims to streamline compliance, provide consistent guidelines, and enhance workplace safety. Facilities must take proactive steps to understand and implement the updated requirements, including reviewing their current Dust Hazard Analyses (DHAs) and updating safety practices.
Key Updates Under NFPA 660
While NFPA 660 retains many of the principles from previous standards, it introduces new expectations:
- Enhanced DHA Procedures: Facilities must conduct thorough DHAs to identify all potential sources of combustible dust and assess the consequences of an explosion.
- Stricter Housekeeping Requirements: More rigorous guidelines to monitor and limit dust accumulation in production areas and systems.
- Risk Assessment Methodologies: Greater emphasis on standardized risk assessments to ensure consistent evaluations across industries.
Facilities should act now to evaluate how these changes may affect their operations and ensure they are prepared for compliance.
IAC's Dust Hazard Analysis Services
At IAC, we specialize in helping facilities identify and mitigate combustible dust hazards.

Example of How IAC Helped a Customer with the DHA & How it Improved their Operation and Employee Health
Many of IAC’s customers work with dangerous and hazardous materials. When creating solutions for handling harmful materials, IAC works quickly to help these organizations create safer processes for their employees and production. IAC did this recently by taking a few fast measurements and rapidly creating a custom component to eliminate the spread of a harmful powder in an ingredient facility, which took numbers from three and a half times the exposure limitation to less than 10% of the threshold.
