We just had a GC doing demo on a wall and cut the sprinkler off with a
saws-all. This sprinkler was on the OTHER side of the wall. Of course this
was at 9:00pm on a Sunday night. I figured about 600 gallons later the FD
shut the PIV. I'd say leaving them in the wall would be a bad thing.

Good morning to All:

My past experience says that (where the sprinklers are in the  walls) -
someone is going to come along and drive a screw, nail, punch a hole  for
whatever reason and then, Bingo. My fear is future wall penetrations - we
have experienced this with the sprinkler piping when we ran vertically  up
walls with sidewalls, sure enough, some drove screws in to the CPVC
"hidden"  in the walls. Code or no Code, they are asking for real trouble.
Won't  even hazard a guess as to how the insurance carrier would handle
the  "loss"...

Regards-

Jerry

>From  NFPA 1 (2012) with cross references to NFPA 101. Note that the last
sentence  in the Annex implies that the equipment in concealed spaces

4.5.8.3* Existing life safety features obvious to the public,  if not
required by the Code, shall be either maintained or  removed.
[101:4.6.12.3]

A.4.5.8.3 Examples of such features include  automatic sprinklers, fire
alarm systems, standpipes, and portable fire  extinguishers.
The presence of a life safety feature, such as  sprinklers or fire alarm
devices, creates a reasonable expectation  by the public that these safety
features are functional. When  systems are inoperable or taken out of
service but the devices remain,  they present a false sense of safety.
Also, before taking any life safety  features out of service, extreme care
needs to be exercised to ensure that  the feature is not required, was not
originally provided as an alternative  or equivalent, or is no longer
required due to other new requirements in  the current Code. It is not
intended that the entire system or  protection feature be removed.
Instead, components such as  sprinklers, initiating devices, notification
appliances, standpipe hose,  and exit systems should be removed to reduce
the likelihood of relying  on inoperable systems or features. Conversely,
equipment, such as fire or  smoke dampers, that is not obvious to the
public should be able to be taken  out of service if no longer required by
this Code. [101:  A.4.6.12.3]

Yes, it is true that we install sprinklers in concealed  spaces that are
not "visually" inspected because it is not required by NFPA  25. However,
those situations are required by code. This situation provides an
inherent risk with no real benefit. Can you imagine the egg on your
face/the  industry if someone tried to punch a wire/conduit through the
wall and  activated the sprinkler causing water damage? I say take it out.

Subject: sprinklers buried in  walls

I have a job that has an existing upright sprinkler system in  which the
GC has already built the walls to the deck and has encased some of  the
existing sprinkler heads in the walls.  He is asking if we can just  leave
them and cut in new heads as needed.  Is this acceptable per NFPA  13?

Thanks,

Dewayne
