Automatic Sprinkler Systems Handbook


The first automatic fire extinguishing system on record was
patented in England in 1723 and consisted of a cask of
water, a chamber of gunpowder, and a system of fuses. In
about 1852, the perforated pipe system represented the first
form of a sprinkler system used in the United States. In
1874, Henry S. Parmelee of New Haven, Connecticut,
patented the first practical automatic sprinkler.
C. J. H. Woodbury of the Boston Manufacturers Mutual
Fire Insurance Company and F. E. Cabot of the Boston
Board of Fire Underwriters completed a study on the performance
of sprinklers for the Factory Mutual Fire Insurance
Company in 1884. This study was the basis for the first
set of rules for the installation of automatic sprinkler systems
that were developed by John Wormald of the Mutual
Fire Insurance Corporation of Manchester, England, in
1885. In 1887, similar rules were prepared in the United
States by the Factory Improvement Committee of the New
England Insurance Exchange.
By 1895, the commercial growth and development of
sprinkler systems were so rapid that a number of different
installation rules had been adopted by various insurance organizations.
Within a few hundred miles of Boston, Massachusetts,
nine radically different standards for the size of
piping and sprinkler spacing were being used. This problem
led to the creation of NFPA 13 and the formation of the National
Fire Protection Association in 1896.
In many respects, the issues that led to the development
of the first edition of NFPA 13 are relevant today. The unprecedented
development of sprinkler system products, design
techniques, and installation practices over the past
several years is offering numerous options for effective system
design. While this increased flexibility provides numerous
advantages, it also requires more diligence by those
designing, installing, and approving sprinkler systems as the
rules for various system components become less uniform.
As has been the case for more than 100 years, the intent
of NFPA 13 is to provide a means for analyzing sprinkler
system information and presenting it in a form that will lead
to effective system designs and installations. This task continues
to become increasingly demanding as scientific and
other discoveries generate information at an increasingly accelerated
rate. In response to these challenges, in 1997
NFPA expanded the scope of NFPA 13 so that it became the
most comprehensive document addressing sprinkler systems.
NFPA 13 addresses sprinkler system installations for all
types of facilities regardless of the type of fire hazards present.
NFPA 13 contains sprinkler system design and installation
information from more than 40 NFPA codes and
As the scope of NFPA 13 has expanded, so has that of
the Automatic Sprinkler Systems Handbook. This 11th edition
includes new and updated commentary on the protection
of three new special storage arrangements in Chapter 20
and new shelf storage arrangements.
Other major changes in the 11th edition include revisions
to the density/area curves for the protection of storage
occupancies and the combining of large drop sprinkler and
the specific application control mode sprinkler information
and revising the terminology to now identify them as control
mode specific application sprinklers (CMSA).
In Chapter 9, a number of changes occurred regarding
sway bracing of sprinkler systems, including the introduction
of new zone of influence tables for Schedule 5 steel
pipe, CPVC, and Type M copper tube. The basis of the values
in these tables is described in a new Annex E.
To continue to correlate with SEI/ASCE 7-05, Minimum
Design Loads for Buildings and Other Structures,
NFPA 13 has adopted the SEI/ASCE approach to converting
strength design to allowable stress design, which is further
detailed in Chapter 9, Annex E, and the related commentary.
Other significant changes include those for calculating
the rack shelf area. In addition, the handbook includes updated
commentary on those portions of NFPA 13 that have
been revised. Also, there are three new supplements intended
to provide up-to-date information on sprinkler statistics,
new and on-going sprinkler system research, as well as
an international perspective on fire sprinkler technology and
installation experience. Another new supplement included in
this edition highlights the major code changes in NFPA 13
