Fire system & Storage, Spec Haz,etc; Summary palcard posted on riser
(OP)
Chapter 24 of NFPA 13 has something i have never seen. This is a project summary of the storage heights, combustible liquids, etc that the sprinkler system design was based on. This is to be hung on the riser. Keep in mind, this is in addition to the typical hydraulic design placard that is required, that only gives the design, BOR flow, etc. Also, this is in addition to the high pile permit report that often gets filed away, and is never seen again. It's a placard sign on the riser. Seems like a great idea. I am in alot of buildings, and i have never seen one of these posted in so-cal. Curious what others are finding in their area. Link attached.

Have not seen one yet, but have not done a system that needs one
Also if you look in the 2010 edition under anti freeze, a placard is also required for anti freeze systems

FYI I wrote about this subject in the NFA Coffee Break Forum in March and I got about a dozen telephone calls or e-mails from jurisdictions who were not aware of this provision, which was first introduced in the 2007 edition of NFPA 13.

The metal hydraulic placards are one problem. As currently shown in the example in the 2010 handbook, most of the time these are filled out using magic markers but where I am it is hot, humid downright tropical. It might be the heat but I can tell you if you fill one of these out inside of five years you will not be able to read it. I don't know where the "ink" goes but it is gone usually replaced by one or two black dots.
How do you fill out the density area placard, that has to be metal, for an ESFR system or something that requires end head pressure? There is no "area" but a head count and there isn't a density either so how do you fill one out? What I do is put down "12 heads" in the area and "52 psi" or whatever in the density box then fill the required supply at the base of riser.
I got job we are finishing up tomorrow; 900 ESFR sprinklers and before me is the placards I just finished. Metal signs and magic marker.... looks pretty and all but I know in five years there is no way any of us will be able to read it. Yeah, and then there is the metal letter punches.... right, we all use that.
I would like to see the hydraulic and design placard combined into one sign and let's forget the metal... 1954 happened a long, long time ago. What we need is a special "picture frame" where you can seal a printed document inside so water/moisture can't destroy. I know it isn't metal but it would still last longer with our marked up metal magic marker signs. How about if NFPA 13 specifies "archive paper" and "archive in" in an "approved water proof frame" mounted next to the riser? I would like to see 8 1/2 x 11 frames so you could even include a small diagram showing where the riser is, locations of the inspectors test connection and any low point drains. 20 years from now whoever inherits that system will appreciate that little sign.
This way we could make up our own signs that more fit what we are doing.
