The 2026 NFPA 660 Checklist: Is Your Facility Ready?

The regulatory landscape has shifted. With the consolidation of combustible dust standards into the unified NFPA 660 Standard, the "gray areas" of compliance are gone.

If your facility completed its initial Dust Hazard Analysis (DHA) around the 2020–2021 cycle, you are now in the mandatory 5-year revalidation window. Auditors are moving through industrial sectors looking for gaps between your paperwork and your plant floor.

We created this self-assessment tool to bridge that gap. Based on the new NFPA 660 guidelines, this checklist helps you identify "invisible" risks before an inspector does.

The Hidden Risks in Plain Sight

Compliance is rarely about the obvious hazards; it’s about the invisible ones. You might have a dust collector in place, but do you know exactly which materials in your facility are creating combustible dust during normal operations?

Consider this: Under NFPA guidance, dust particles smaller than approximately 250 microns—roughly half the size of a grain of sugar—can present a severe combustible dust hazard. These micron-sized particles often accumulate in places standard housekeeping misses: on overhead beams, inside lighting fixtures, and behind heavy machinery.

If your housekeeping team is using compressed air to blow this dust down, they aren't cleaning; they are creating a suspended fuel cloud. If they are using standard shop vacuums with non-conductive hoses, they are introducing a high-voltage ignition source into that fuel cloud. 

It challenges you to answer the hard questions before an external auditor asks them:

• Is your DHA current? Has it been updated to reflect changes in your materials, processes, or facility layout in the last five years?
• Is your equipment safe? Are your vacuums fully bonded and grounded to prevent static discharge during routine cleaning?
• Is your team trained? Are housekeeping methods consistent across every shift, or does safety drop off when the sun goes down?

The DuroVac Standard

Our systems are built to answer "Yes" to every compliance question. Whether it's the PowerLift Series for heavy spill recovery, the Lifetime Series for sub-micron filtration, or our specialized Elevator Series for hazardous metal dusts, we ensure your equipment is an asset to your safety program, not a liability.
