Guidance on System Layout
Modifications to NFPA 13 Contained in Other NFPA Documents KEN WAGONER | Parsley Consulting
NFPA 13, Standard for the Installation of Sprinkler Systems, is a lengthy document, and it provides guidance on design of fire sprinkler systems for a variety of hazards, including factories, dwelling units, water-cooling towers and marine piers, wharves and terminals. Starting with the 1999 edition, it included the consolidation of the standards related to storage of various commodities into its pages, which made NFPA 13 the resource for layout of an automatic sprinkler system for most conditions. However, there are still situations where NFPA 13 alone does not provide the criteria needed for design.
In Section 2.2 of NFPA 13, 2010 edition, the document lists 28 documents which are to be considered as part of the standard. These range from NFPA 11, Standard for Low, Medium and High Expansion Foam, to NFPA 5000, Building Construction and Safety Code. It would be fairly well under- stood by most layout technicians that some familiarity with
NFPA 14, Standard for the Installation of Standpipes and Hose Systems, would be a requirement for design and installation of a standpipe and hose system, just as an understanding of the information in NFPA 20, Standard for the Installation of Stationary Pumps for Fire Protection, is necessary when provid- ing a stationary pump for a sprinkler system. While NFPA 13 does contain extracts from other documents, such as Chapter 10 which is lifted directly from NFPA 24, Standard for the Installation of Private Fire Service Mains and Their Appurtenanc- es, the information in Chapter 21 (moving to Chapter 22 in the 2013 edition) serves to direct the layout technician to another standard which contains information that must be adhered to in sprinkler system design. Some of the paragraphs in that chapter contain explicit design criteria while some only identify additional documents to be followed.
Two such examples of referenced documents containing mandatory information for sprinkler system layout would
