Thanks everyone for the information. I figured it couldn’t be as simple as
a paint spray booth. I will check with the specifying engineer for more
information. They didn’t mention the dust collector on their initial basis
of design. It was added as an alternate to our contract. My first
Thanks, I will check there.

I have done many Dust Collectors and find FM Data Sheet 7-73 as a good guide.

When NFPA 654 refers back to NFPA 13, the only section dealing with protection
of ducts conveying hazardous material is in the Special Occupancy section under
Spray Application Using Flammable or Combustible Materials as you mentioned.
It also wasn’t stated what type of dust as that can also
Is the "dust collector and associated ductwork" combustible or is it all
made of metal and the dust combustible? Sorry, I couldn't help myself. You want
to look at *NFPA 91, Standard for Exhaust Systems for Air Conveying of
Vapors, Gases, Mists, and Particulate Solids.*
Flamex has been around for several decades, I believe under a couple different
corporate ownerships. It is not a new technology.
I’m more used to seeing as part of an overall dust explosion control system.
Usually I’ve worked with a mechanical engineer whose specialty is dust
explosion

I have a little experience with this. I have seen a system brand called
"Flamex" on the dust collection ducts. This system uses flame sensors and
solenoids to extinguish a fire in the duct, which is a better system than
just installing sprinklers in there. I can say that installing sprinklers
I am trying to figure out the proper design criteria for a combustible dust
collector and associated duct work.
NFPA 654-2020ed section 9.3.5.2
NFPA 652-2019ed section 9.8.5.3
Both refer you back to NFPA 13
There is no section on NFPA 13-2013 for dust collectors. The closest I can
find is
