I have heard this quoted from various sources :

"The National Fire Protection Association has no record of more than two deaths 
in a completely sprinkled building where the system was properly operating. 
Fire sprinkler systems are very effective and may cut fire deaths by one-half 
to two-thirds in properties where they are installed. (Congressional Fire 
Services Institute)"

Subject: RE: Boat Storage

Given a properly designed, installed and maintained sprinkler system.  

Do exits matter?  How many cases do we have of a bedroom catching on fire where 
the sleeping occupant wakes up from getting wet or in the recent case didn't 
wake up.

Do rated separations matter?  I've seen fires in the unsprinklered side go 
through code complying rated walls only to be stopped by the sprinklers with no 
fire damage to the sprinklered side.  How about the high rise fires that burn 
until they reached a sprinklered floor.

Does smoke control matter?  If there is residual smoke it's minor and well 
diluted.

Do fire hydrants and access roads matter?  In 10 years with an average of 16 
sprinklered fires in St. Paul, MN I was only aware of the use of the FDC 4 
times.  And actually 2 of those were for the standpipes in unsprinklered 
buildings.  I talked to the Chief's on most of those calls about issue they 
had. 

Fire alarms?  I contented if it's sprinklered fire alarms should not operate.  
Fire alarms are to warning people about uncontrolled fires that are a threat.  
Uh, if the sprinklers operated is it a threat? Do you know there is a trend in 
FD's only sending a Chief or one company to investigate water flow alarms or 
fire alarms.  The FD's get it, the number of alarms where that is the only 
indication of a problem that result in fire is about 0 (not 0 but real close).  
In 18 years of riding big red trucks I never went to a fire that was only 
reported by an alarm.  These FD's send a full assignment if they get a phone 
call that follows up on the alarm. 

Basically where is the body count?  I've been on this forum for a very long 
time I don't recall any discussion ever about a fire death in a sprinklered 
building.  I've always asked national figures in conversation about actual fire 
deaths in sprinklered buildings that they have been a part of.  So far none is 
the answer.  Back in '99-'00 when I saw shepparding through the IFC requirement 
for all buildings with an R be sprinkler I asked the committee about their 
knowledge of fire deaths and sprinklers.  Either they had none
or thought I was being rhetorical.   Where is the cost benefit of further
mitigated losses with the other stuff after sprinklers?     

So one might argue about the balanced design crap and the possibility of 
sprinkler failure.  If it's properly designed, installed and maintained has 
there ever been a failure?  Maybe but rare.  We also know really bad sprinkler 
jobs still put out a lot of fire.  We tried all the other fire protection 
schemes with in my opinion limited success.  Talking about the code from 
Hammurabi to the early 1980's.  So if the proper or incorrect sprinklers fail 
we are back to the designs of the yesteryear and we know the outcome.  We have 
the choice to put money into the backup plans which will fail or money into the 
sprinkler to make sure they don't.  This is a cultural shift that is occurring 
since the late 1980's.  And just like our vested interests pushing on direction 
the lobbies for the other interests are arguing the opposite slowing the proper 
transformation.

So I wasn't bashing FPE's.  I also wasn't suggesting how one gets a proper 
system - that may or may not involve an FPE.  I was summarizing all the other 
FPE type stuff as marginal effect after proper sprinklers.  

I know there are exceptions to every thing I said.  For every exception anyone 
can come up with 1000's of examples exist of the normal.  Perhaps someone has 
knowledge of a fire death in a properly sprinklered building.  I think Joe 
Hankins once spoke of 4 deaths but I recall something wasn't right.  From a 
minimum public policy point of view I don't see the point in planning for the 
exception when they are very, very, very rare. 

Or perhaps it's just my memory?

Curious comment. Care to expand on that?
