Thanks, Travis. I thought that I had the wrong reference.
Once upon a time it SAID don't use 1/2" heads when the density is .25 or
more.
Or, am I crazy?
Forum moderator: Please limit number of answers!
thanks, Vince

The key thing in NFPA 13 is LOCATION MATTERS. The statement about needing ≥K8
at ≥0.20 density and ≥K11.2 at ≥0.34 density is in Chapter 12 of the 2016
edition. Chapter 12 is for storage. So, you could extra hazard grp II and use
K8 sprinklers because it is not storage.
As Roland Huggins would always remind me. LOCATION MATTERS.
So, if your project is storage, that comes in to plan in the General
Requirements for Storage section. If it is not storage, then those sections
don’t apply.

Subject: .25 or better
Good morning, forum
Can someone give me chapter & verse of the NFPA 13
statement that you can't use 1/2" heads when the density
is .25 or better?
thanks, Vince
