Agreed.
This may be my last post for a while as I will be employed by another SC state 
agency.
I just want to say that I have greatly enjoyed the code discussions on this 
forum that help us all understand the codes and standards better.  I will not 
name names but I think we all appreciate those who are more knowledgeable than 
ourselves on certain subject donating their time to educate those of us who 
either didn't know something, didn't have the confidence we were right, or 
couldn't find something and were led to the answer.

Tomorrow is my last day here at the SC Office of State Fire Marshal as I am 
upgrading from my state level fire official role to a state level building 
official role.  I will be sure to have opportunities to educate the architects 
and engineers from that position on the proper utilization of fire sprinkler 
systems when I conduct my plan reviews as well as more time in the field making 
sure the plans are replicated in the actual construction.

Keep up the good work and if you do work on schools in South Carolina, you may 
see me involved on your project.

Respectfully,

David Blackwell

When the IBC/IFC doesn't provide a specific definition we are told (ref. 2018 
IFC) 201.4 Terms not defined. Where terms are not defined
through the methods authorized by this section, such terms shall have 
ordinarily accepted meanings such as the context implies. Merriam Webster's 
Collegiate Dictionary, 11th Edition, shall be considered as providing 
ordinarily accepted meanings.

Throughout means throughout.

We've just been through this definition issue with a local architect.  Omission 
of sprinklers in a Control room with Sapphire provided is acceptable as an 
alternative by the AHJ but the building loses all advantages or allowances that 
are given to a fully sprinklered building since taking out sprinklers and 
substituting a gaseous system no longer qualifies as being sprinklered 
throughout.  Basically any part of the code that allows you to do something a 
little more risky or bigger, higher, wider or of greater quantity or whatever 
based on a fully sprinklered building or where sprinklers are installed 
throughout, now goes away and you can't do those things.

The Commentary spells this out in great detail.  2018, IFC Commentary, 903.1.1.

Subject: [EXTERNAL] IBC "throughout"

There are countless sections in the IBC that say sprinklers shall be  " . . 
.installed throughout . ." or ". . .provided throughout . ." or  ". .equipped 
throughout . ." or something similar.  But I don't' see where the IBC tells me 
what "throughout" means.  I've assumed it meant sprinklers in all areas that 
the applicable NFPA standard (NFPA 13 in this case) requires them, but not in 
areas that the applicable NFPA standard allows them to be omitted.  I've 
learned, since the IBC doesn't define the term, there are jurisdictions that 
define it differently - more specifically they don't recognize the omissions 
that NFPA 13 allows, only the exempt locations listed in IBC section 
903.3.1.1.1.

Is anyone aware of an IBC document that would shed some light on this?  I've 
found a number of articles from consultants, associations, etc., but something 
directly from the IBC would carry a lot more weight.
