AFSA Technical Update ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ A newsletter dealing with codes and other technical issues June 6, 2014 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ NFPA 13R Carports "We have a 13R project that is a 4-story structure, stick framed that has parking on the first level. On the bid documents these areas are listed as "carports". Based on section 6.6.5 and associated commentary, sprinklers may be deleted from these areas. The AHJ is telling us that because there are three walls that this is not a carport but it is a garage (based on the city's definition of a carport). There are three walls and the front is open. Are sprinklers required?" We have reviewed NFPA 13R, 2013 edition as the applicable standard. Our informal interpretation is that sprinklers are not required for carports. Section 6.6.5 states, "Except as provided for in 6.6.5.1, sprinklers shall not be required in any porches, balconies, corridors, carports, porte-cocheres, and stairs that are open and attached." The intent is that these do not require protection since they are open and exposed to the outside atmosphere. The commentary from the Automatic Sprinkler Systems for Residential Occupancies Handbook provides a pretty good explanation. It says since NFPA 13R is concerned primarily with providing life safety by way of affordable installations, these exterior areas are allowed to remain unprotected, while still providing an acceptable degree of building protection. Protection of these spaces requires some sort of system that is sensitive to freeze protection in many areas. Providing a dry system, antifreeze system, or listed heat tracing system to protect these portions of the building can add substantial cost with a limited return in life safety. It is understood that this standard is used in many areas where freezing conditions are not an issue. Based on the statistics provided in Table A.1.2, the limited number of fatalities caused by fires that start in these areas does not warrant the sprinkler protection being required in these spaces. Owners can require that their design professionals incorporate sprinklers into these areas, if so desired. The term porte-cochere has been added to the list of exterior areas that do not require sprinkler protection. The word is synonymous with carport, but many authorities were not allowing omission of sprinklers because porte-cocheres were not specifically listed in 6.6.5. There is no requirement to protect porte-cocheres, even if there is occupiable building space above. The word "open," used in 6.6.5, has been a point of contention since the earliest (1989) edition of NFPA 13R. Beginning in the 2010 edition, the committee clarified that if one of these spaces was to be considered open, it was "exposed" to the outside temperature. This differs from requirements in the building codes, fire codes, and NFPA 13. NFPA 13 is very clear that a corridor must be 50 percent open to be considered "open" and remain unprotected. However NFPA 13 is a property protection standard and does not apply in NFPA 13R installations. The model building and fire codes have varying definitions of what they consider to be open. For the 2013 edition, the Technical Committee on Residential Sprinkler Systems has made it very clear that any corridor, stair, breezeway, porch, balcony, carport, or like structure that allows the temperature of the outside atmosphere to permeate into that space is considered "open." ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ firesprinkler.org [http://r20.rs6.net/tn.jsp?e=001ybGXDfoSEUMwWE6UK-glRcTPNPYZUiqnxx-FXQQfJ9ikuQ7UB26tG6poSBDdjS-ZphQFzOa7sUeyDgtjHcNTeiExzjYNiLvbHJI8WO4VIWs=] Hosted by the American Fire Sprinkler Association ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Technical Update is prepared by the Technical Services Dept. of the AFSA: Vice President of Engineering and Technical Services Roland Huggins, a PE registered in fire protection engineering; Phill Brown, a NICET IV certified automatic sprinkler technician and NFPA Certified Fire Protection Specialist (CFPS) and Tom Wellen, a PE registered in fire protection engineering.
