Do laundries within residential buildings require a standard-spray sprinkler, or can they also use residential-style sprinklers? What about corridors?

A building can be designated 13R with portions of the building sprinklered per NFPA 13. An example would be a commercial kitchen within a hotel that is otherwise13R sprinklered, done as an Ordinary Hazard. The laundry should be light hazard sprinklered per NFPA 13 as well as offices, but the corridors should be 13R if the rooms are 13R.

I just want to clarify how Pete answered. He isn't wrong, but he makes it seem you can use both NFPA 13 and 13R in a building, which is not the case.

To clarify, this is the section in the 2007 NFPA 13R. Might be a little dated, so just check which NFPA year the local code adopted.

I may have been mistaken. NFPA 13R allows you to design using NFPA 13 in areas outside the dwelling units. Section 6.8.2.

JAMES, It is confusing, but to clear it up..13R is a permutation of 13. NFPA shouldn't re-write everything in 13 on density-area and pipe schedule calculations,etc. And 13 is more a more stringent standard than 13R. It stands to reason that in most cases 13 can replace 13R, but the devil is in the details. I would certainly get the standard that is current for the jurisdiction and double check everything. I'm looking at the 2013 13R, and there are several areas that point the designer back to 13 for various situations outside of the dwelling units.

Check the code review drawings, and check your state (and/or city) building code. Leave a Reply. |
