Thanks, these references are right on target. However, they are
somewhat vague, presumably because as NFPA 909, A.16.4.8 says, Compact
storage systems present a severe fire challenge that requires
engineering solutions specifically designed for each installation.
Todd, there aren't any catwalks
His reasoning is flawed - He says that the dry system will result in a delay
in water getting to the fire. True enough, but that is why the increased
remote area usually. The engineer specified that the any method of calcs
allowed in NFPA 13 would be acceptable; therefore the largest room rule
Eric,
A couple more questions worth asking. What is the value of the art?
Are we talking Picasso or Elvis on black velvet? Also, are there a
lot of water colors? Sprinklers don't do water colors any favors, nor
does is do any for most paintings. The water damage issue could be
significant.
I went down his road once, thinking that if an area wasn't subject to freezing
then a dry system can't be used. After all, that's just the reverse of the
requirement that if an area IS subject to freezing then a dry system MUST be
used.
There are some who specify this, but after doing much
I would bet money that he is confusing Quick Response with water
delivery time and as others have pointed out the latter is compensated
for in the increased design area when using area density. This I
interpret to be a property protection issue. As to life safety
