Greetings list,
I'd like to just offer yet another opinion on the thread going on regarding
the SC Sofa Store fire and a question earlier on what do / can local
authorities do when / if they find a building with an over taxed or under
designed system in it.
Presumably if you are performing inspec
Need more info. Where is coming from? What is it crossing? If it runs thru
the building there is fire resistant wiring. It must be protected from fire.

Depending on which code you're using, the back-up power circuit from a
generator or alternate second source must be rated cable or
concrete-encased. Not sure about the primary ...

Jamie,
With 13D, usually no domestic demand is required. The exception is when a
multipurpose piping system is being used and it is serving more than one
dwelling unit. See 13D 6.3 2002 ed.

I've used the NCI unit, nice but you can't calibrate it.
I was asked to check one against a playpipe once by FM (at the convention
ctr. here in Boston, site of the NFPA show) and it was WAY off, not even
close at multiple flows, both under and over. I wouldn't recommend it. I

Great question. The answer is yes we can legally stop them from storing
illegally. If the building is sprinklered and the commodity changes,
they have to prove to the AHJ that there is enough density in the system
to handle the commodity. I explain to the responsible party that they

John,
I'd appreciate hearing some of the feedback you get. I'm looking at a
job where that might be appropriate.

Ditto.
I see it regularly. 11,500 square foot spec building with 25 foot
ceilings and 14 foot tall doors. Just under our local requirements for
sprinklers -- actually one guy split his building into three so he
didn't have put sprinklers in. Nearly every time I see a new tenant move

It will come down to the fact that as the local AHJ said, when the
building was built sprinklers weren't required. And if
not required why waste the money on something that will never be used.
Since there are no retrofit laws on the books, no requirement to update
the building. Do what you wan
Anyone know if this building was considered or registered as historic?
That might explain the absence of sprinklers, but not the permission to
occupy with a furniture warehouse store.

Most departments have an entry protocol. Unfortunately, the initial

It is scary that as many as 15 firemen were in an unsprinklered building
when the roof collapsed. There could be 15 dead firemen instead of 9.
I have never been a fireman but don't they have procedures for entering
