I am confused. Happens very easily.

If the AHJ determines that you cannot pass through the stair, you can always
provide a rated enclosure (1 hr or 2 hr) around your piping so that the piping
is not "in" the stair enclosure. This is often done with other utility risers.

You need to tread carefully on this one. 2006 IBC 1020.1.2 states
"Penetrations into and OPENINGS THROUGH ...". Peel back to 1020.1 which
states "Interior exit stairways and interior exit ramps shall be
enclosed with fire barriers constructed in accordance with Section 706".
Peel back to 706.6

It's my understanding that the 3 times rule only applies to structural
members when dealing with light hazard (8.6.5.2.1.4) I believe my situation
would fall under 8.6.5.1.2

Brian,
I wouldn't jump to that conclusion... It does say "required" in the IBC
verbiage below which I assume applies to the whole list of exceptions. One
could argue that the only "required" sprinkler piping in the stair enclosure is
the pipe feeding a sprinkler or sprinklers in the stairway.

Standpipe risers in stairs are common, but pipes just passing through the stair
are often disallowed.
Better make sure you know what the local AHJ's perspective is on the matter
because there can be great inconsistency on this issue.

Be careful with this one, in Seattle the Building Official does not allow
sprinkler pipe penetrations of stairways unless is strictly to serve a
sprinkler in the space (eg: no pass through arrangements).

Based on language in NFPA 13-8.6.5.2.1.1 and 8.6.5.2.1.2, the light would be
considered an obstruction. This appears to be clarified in the commentary,
A-8.6.5.2.1.4.
But, why do you need 24"? Using the three times rule, for a light 5" deep,
you would need to be 15" away.
The options could be: (A)
You'll still need to remember to protect any penetrations with fire stopping
details equal to the rating of the stairwell shaft rating.

So if it's a single stairway I can pass my sprinkler pipe straight through,
awesome. I've always routed the pipe out and around a stairway. Thanks for
the info.

I just had an architect send me this since we were running a dry riser thru
a stair shaft to feed attic; technically sounded like he was right, I called
AHJ and he blessed my galv steel pipe running in there, along with the FDC
line and wet system that did service the stairs.

Thanks Rich. The builders loved it, the fire guys hated it. Nice to be
speaking in the past tense about it. It joins the other Haighisms on
the trash heap along with life safety systems (Seattle version), Class
I manual dry standpipes in high rises, etc.). What a wonderful world
it must have been.
Forum,
I've always been taught that you cannot pass a pipe through a stairway, can
someone point me to that section in the code book and or give me your
thoughts on it?

There is certainly some judgment to use. Is a light really a solid
continuous obstruction? String the lights end to end over a bunch of heads
and I'm with you. One light judgment time. OK it's the only head in the
room so all the heads are obstructed so maybe it is a solid continuous
obstruction
Cleaning out the stuffing box drains, every pump room should have one.

Thank you, Tom.

For the record, the allowance to which Ron speaks in Seattle is on the way out
now that NFPA 13R became more explicit in the 2010 edition. And I might add,
that allowance came well before my time here, I just try to clean up the messes.
