Craig,
You've missed my point completely.
There are times when the 3,000 sq ft minimum from IFC would kick in.
The point WAS ... NFPA 13 AND the IFC work together to allow differing
densities in different areas, but sometimes the minimum remote area may be
larger than that specified in N
Cecil,
Connecting the IFC and NFPA 13 dots is not always easy. Many design
professionals and code officials use Section 2704.2.2.3 to reduce the

a minimum one-hour fire barrier separating the Group H use from any

Thanks for the advice. I did basically what you have suggested, but as far
as the suggestion about "a proposal to install a steel flat or angle

The fire protection design for oxidizers and many hazardous materials is
dependant on the proper classification of the hazardous material. You've
already asked about a deviation to NFPA 430 but it's unclear if the room
is separated to allow one to reduce the design area, which is allowed by
the IFC

If the space is only 450 sf, calculate just the room at the .20. There's no
point or requirement to calculate an entire 3750 sq. ft. area if the adjacent
areas do not require the same density based on their hazard and this space is
