What jumps out to me is the spray foam insulation. I’m not sure that the
requirements for a typical paint spray booth would be applicable. Two very
different products. I would look for any research or testing done on that
specific product. Also the MSDS for it as a liquid and a
See the video below. Fast forward to the spray foam test at about 3
minutes in. Spoiler: flashover takes 44 seconds. Since you are probably
acting as the only fire professional on this project, I would suggest you
share the video with your customer so they understand the gravity of the
And this seems to be the difference between the Classification of the
Occupancy/Commodity (hard part performed by EOR) and figuring out what
sprinkler and spacing to use in a particular compartment with clouds, soffits,
skylights, beams, joists, hidden spaces, piping configuration, hanger
Does anyone have advice as to how one would calculate a "spray booth" for
spraying foam insulation that is approximately 90' tall X 25' diameter with
five levels of working platforms?
Typically, when I have done paint booths for vehicles (even as large as fire
trucks) I have calculated the
I think making the new SC sprinklers standard-response is the best solution
in this particular situation.
I could see these EC sprinklers being used as both 20'x20' and 14'x14' in
the same compartment in order to protect odd-ball areas. Then adding new
SC sprinklers and deciding if they should
We follow how they are listed. If the 3mm bulbs are spaced at SR, we utilize SR
5mm bulbs for adjacent standard coverage sprinklers.

I would say if they're all being used as an SR sprinkler based on listing, I
would put in SR sprinklers. Is there an AHJ you can lean on? That's what I
would approach them with as far as logic.

Forumities,
This has likely been previously addressed, but it's just not coming back to
me . . .
I've got an existing ordinary hazard area that is protected by existing EC
sprinklers. The existing EC sprinklers have fast response (3mm) elements
and are listed as standard-response for the
FM also has some guidance in its data sheets. They are more conservative in
their design criteria though.

I wrote an article on this in the May/June issue of Sprinkler Age:

In general, minimum 15 minute duration, and then two different refill rates
depending if your stored capacity is less than or greater than 30 minutes.

I have never designed a system with a break tank, however I am working on one
project where this may be a viable option. Is there any good information one
designing a system with one of these?
