NFPA 25: 4.1.8 Information Sign

NFPA 25: 4.1.8 Information Sign

NFPA 25: 4.1.8 Information Sign

(OP)
So. NFPA 25: 4.1.8 Information Sign.
4.1.8.1 A permanently marked metal or rigid plastic information sign shall be placed at the
system control riser supplying an antifreeze loop, dr y system, preaction system, or auxiliary
system control valve.
4.1.8.2 Each sign shall be secured with a corrosion-resistant wire, chain, or other approved
means and shall indicate at least the following information:
(1) Location of the area served by the system
(2) Location of auxiliary drains and low-point drains for dry pipe and preaction systems
(3) The presence and location of antifreeze or other auxiliary systems
(4) The presence and location(s) of heat tape

This is shown with the vertical bar next to it indicating it’s a new item for the 2011 edition, but as per the handbook:
The sign required in 4.1.8 is needed to provide anyone maintaining a system with vital information
that might not otherwise be readily known. The sign is particularly useful in addressing
freeze threats by identifying any locations with heat tape, and acknowledging that auxiliary
and low-point drains are installed on the system along with their number and location. If
this information is not known, the system can be damaged due to freezing of water in the
trapped sections of pipe. It is important to recognize that this is a retroactive requirement. For
example, system information signs were not required by NFPA 13 prior to the 2007 edition,
so many systems may not have them. Because it is a retroactive requirement in NFPA 25, it is
required for compliance.

We have started to do these as part of the report; our guys fill out a sheet while they’re doing the inspection and we simply laminate the sheet and either go back and attach it ourselves or send it with the report to the owner / owners rep. I’m pretty sure a laminated piece of paper doesn’t meet the intent of 4.1.8.1 above but doing so would be both time consuming and expensive. I was wondering what others might be doing here if they are doing it yet.

RE: NFPA 25: 4.1.8 Information Sign

Light,

I also use laminated papers and attach to the Riser.
Until the industry makes these steel signs what else can we do?
I'm not going to custom mfr a sign that nobody else is installing

RE: NFPA 25: 4.1.8 Information Sign

OK guys,

While we are in the subject, how do you use to input the information in the sign above? I have seen grease pencil, sharpie. I tell them that they can scribe the information or take the sign to a trophy shop and have the input the information. I have seen too many signs with the information rub off to allow permanent marking.
