Charles, Ron, this is off topic. I can beat the story about the cardboard
box. There is a resturant here in Eastern Oregon, I serviced the Ansul
once. The Ansul defiencies bothered me enough so I would not do the service
again. The hood was made of alumiminum and single wall duct, not grease
tight. A few years later, a class reunion was held in the resturant. We
went, and I noticed the exhaust hood and appliances were gone! The kitchen
was moved into the back room. I went over and peaked in the back room and
there was a new hood over the appliances. I was disappointed to see the new
exhaust hood was not protected by a fire suppression system. But the lack
of a suppression system was not the real problem. The hood did not meet any
UL, NFPA or IMC standards. It was made of cardboard! Yes, the hood was
made of cardboard. The duct tape that held the cardboard to the wall and
the duct probably did not meet code either. But, they did not have to worry
about grease build-up in the hood, they just replaced the cardboard box.
You just cannot make this stuff up!

Hello Ron,
Actually happened in a body shop here after the city inspector told them
they needed "Sprinklers" in the spray booth (non sprinkled building) 3/8"
poly from the saddle tap under the water cooler ran 50' across the building,
Then split to the 2 heads in the spray booth. City inspector "approved"
their installation 5-6 years ago and is still like that.

increase that to a really big pipe like 1" after tapping the line that
goes
to the water cooler.

Hi School, Sophomore to Senior
Permit? Not a chance, No Way. Does that cost more?
This is the third sheet rock booth I have seen. None were permitted or
inspected.

Is this a K-12 school, or a community college. Adult education usually
defaults to a B-occupancy, then goes to special occupancies or uses. If
it
is a high school it should be an E-occupancy.
Spraying in an E-occupancy normally requires a paint spray room. Booths
are not an option in E occupancies. See IFC 2404.2, IBC, IMC, and adopted
electrical code.
Was the booth installed under benefit of permit?

Not sure there's a recognized 90 minute assembly. There are one and two
hour, but I think the architect would have a hard time gaining approval
for a 90 minute assembly without an appeal or approval of alternative
means and methods of construction. For this type of booth (we've done 3
in
high schools recently) the industry standard for pre manufactured is
either one or two hour.

Can the room design method be applied provided the walls of the room in
which the paint booth is located, are 90 min fire rated ?
If the room is under 2500 sq ft it will make a big difference in the
water
supply and storage.

Yes, but if it's not rated I would say you need to do a design for EH II
that encompasses the booth, the mixing room, and adjacent spaces
(assuming
no 2-hour separations from adjacent uses) up to the required design area
in
11.2.3.1.1.

I have been asked by a local school district about protecting an
automotive
paint booth. The catch, the booth is 2 x 4 framed, covered with sheet
rock.
The exhaust duct work does not have filters, and the exhaust fan may not
be
rated for hazardous paint fumes. The booth does not meet any UL
standards,
so I cannot install a dry chemical suppression system. Will a water
based
sprinkler work?
