AFSA Technical Update ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ A newsletter dealing with codes and other technical issues May 24, 2013 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ NFPA 13R Exterior Corridor "I have an AHJ quoting the 2013 NFPA 13R referring to the open walkway and is saying that sprinklers are required since it is a balcony. What is your interpretation of this requirement?" We have reviewed NFPA 13R, 2010 edition that you indicated as the applicable standard as well as the 2013 edition. Our informal interpretation is that sprinklers are not required in the corridor. The 2013 edition is very similar to the 2010 edition requirements. The 2013 edition in Section 6.6.5 is explicit where it 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 annex for this section says an example of an open corridor, stair, or breezeway is one that is exposed to the outside atmosphere (temperature). Another example is an exterior wraparound corridor that is typical in a two- to three-story motel. [See Figure A.6.6.5(a) through Figure A.6.6.5(e).] The 2013 handbook commentary says that 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 new 6.6.5.1 in the 2013 edition also states, "Where a roof or deck is provided above, sprinklers shall be installed to protect attached exterior balconies, attached exterior decks, and ground floor patios serving dwelling units in buildings of Construction Type V." The handbook commentary under this section says that the committee has made a major shift regarding porches, balconies, decks, and ground floor patios serving dwelling units in buildings of Type V construction. Type V construction applies to the entire building, and not just the construction of the balcony. This rule applies to the exterior or "open" spaces accessible only from the dwelling unit itself, and not a corridor or breezeway that is shared among multiple dwelling units. The previous sentence provides a key statement regarding your question. As such, sprinklers are not required in the corridor. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ NFPA 13 Public Inputs Due May 31st NFPA is soliciting input for the 2016 edition of the NFPA 13 standards.
