There are NFPA 14 excerpts, with commentary, included in the front of the 2007 NFPA 20 Handbook for Stationary Fire Pumps
Depending on what you are looking for, this may help.

Just a thought,
the general storage rules in NFPA 13 state that OH1 can protect Clkass I and Class II Commodities. It says nothing about Class III or Class IV or Group A Plastics. These fall under OH2.
May seem to be picking nits, but I find it difficult to believe that these closets, no...
Based on this information, YES, you must provide branchline restraint for the 2-in. branchlines.

It depends. You may not dismiss branchline restraint just because the mains attached are braced.
What size are the branchlines? How long is the run between the mains? How are the branchlines hung, ie, how long is the hanger assembly?

Other than the exceptions for sidewalls underneath garage doors in NFPA 13, sidewall heads need a ceiling above them and a wall behind them.
I'd be curious to hear that equivalency suggestion.

Just because you got it past the reviewing authority does not make it right. Many authorities do not have the expertise needed to catch this...
Arsnman4,
Firstly, I agree with Travis. Clearly ESFR does not work for very many flammable/combustible liquid design scenarios.
Secondly, you need to get an FPE involved and determine what level of protection you actually need besides the ESFR.
Thirdly, is this a situation where they want the...
They would only possibly have standard response heads if they were already previously sprinklered, thus the wording
"modifications or additions to EXISTING systems"
If you are providing new sprinkler protection systems, then they will be Quick response, not standard response.
Thanks for the...
If you have no fire protection design experience, I am wondering how you could possibly supervise fire protection designers. This is not something you can "cram" for.
Good luck to you in your interview.

Shawn,
You may need to get help from a qualified (competent) engineer on this one. If you do not use the tables and parameters outlined within NFPA 13 (which many have argued contains all the engineering so you don't have to), then (as others have argued previously), you are interpretting...
Travis,
Honorable Mention:
The requirement to include additional ESFR heads (installed due to obstructions) in hydraulic calculations has gone away.

Stookey,
I stand corrected, partially.
You are correct in that IBC requires control valves and flow switches on any riser, whether it is a combination standpipe riser or dedicated sprinkler riser, in High Rise.
However, IBC also refers to NFPA 14. NFPA 14, 2007, 6.3.5.1 states that "each...
Travis,
as you are finding here in this situation, Building Codes and locally adopted Ordinances ALWAYS trump the NFPA 13 Standard (NOT a Code). In general, I think many believe (not necessarily You) and incorrectly so, that NFPA 13 is it, and if they comply with NFPA 13, they are finished...
pipesnpumps,
I want to know why an expert opinion advisor for the State of NJ and NICET Level 3 ITM who wants to stamp drawings did not already know this.
pipesnpumps,
We are saying the same thing here. An FPE does not have to be an engineer that attended Univ of Maryland and received a Fire protection degree, but rather, an engineer that took and passed the FPE PE exam. That would be most preferable, but I would also agree there are many other...
Along the same lines of what pipesnpumps is saying, I will take it one step further.
You are NOT qualified to be making these decisions. I suggest you consult a qualified fire protection engineer or contractor for assistance.
Exposed expanded plastics is very dificult to protect, even with ESFR. You combination of 35-ft high roof deck, and 25-ft. max storage height is almost a loser.
It appears that you could make K25 ESFR work using a 12-hds@60-psi design. This design is for exposed expanded plastics up to 25-ft...
