Committee Statement

CommitteeStatement:

At a recent ICC code hearing, there was extensive discussion about whether the 4-story limit inNFPA 13R relates to grade plane, as defined in the building code. It does not.

Although the existing NFPA 13R text was thought to be clear that the 4-story limit is not with respectto grade plane (which is why "in height" was repeated in the existing scope text), it has becomeapparent that the existing text needs to be slightly adjusted to better convey this point. This isparticularly important with respect to application of NFPA 13R to buildings that are constructed inaccordance with pedestal building options under model building codes. Proper application of thestandard to pedestal construction, consistent with this proposal, is clearly conveyed in the NFPAResidential Sprinkler Systems Handbook, but adjusting the scoping text should help to eliminate anyremaining confusion.

Committee Statement

CommitteeStatement:

In many residential buildings, there are private garages that exceed 400 square feet. However,many of these garages are protected with residential sprinklers or standard sprinklers with a .05density. These concealed spaces are generally wood floor trusses with dwelling units above. Theconcealed space itself is technically light hazard and in most cases it is a rated assembly. In thespirit of providing life safety verses property protection, non metallic piping should be allowed to runin these spaces even when the room is greater than 400 square feet.

New Section 5.2.2.1 is a clarification and makes NFPA 13R consistent with Section 6.3.9.6.1 ofNFPA 13.

In residential buildings with ordinary hazard rooms larger than 400 square feet, the installer isrequired to transition from listed nonmetallic pipe to metallic pipe. New Section 5.2.2.2.2 eliminatesthat issue. The requirement to install the pipe or tube within a 1-hour fire resistance-rated assemblywill insure the integrity of the piping systems until the sprinkler heads activate.

Committee Statement

CommitteeStatement:

Ventless clothes dryers placed within closets have the potential to raise ceiling temperatures above100 F (38 C) for sustained periods of time, potentially weakening the operating mechanisms ofordinary temperature rated fire sprinklers over months or years of use, leading to inadvertentoperations. While ventless clothes dryers have been used in Europe for many years, they are fairlynew to the North American market, where vented clothes dryers have been the norm. Moreexpensive than vented dryers, they generally incorporate condensers in a “two-loop” system to firstheat some incoming air, allowing it to absorb moisture from the damp clothes, then continuallycondense the heated moist air to release the water before recirculating the resulting dry air within theclothes dryer. Unlike vented dryers, where moist heated air is exhausted to the building exterior, thesedevices capture the water to a drain or pan, while the heat from the condensing cycle is exhaustedinto the immediate area.

The condensers in combination machines that both wash and dry the clothes are generally water-cooled, such that quantities of cold water are used to condense the moisture evaporated from theclothes during the drying cycle, and pumped away through the drain line. But the standalone dryerunits are air-cooled, using the ambient air as a heat sink. While this heat can be dissipated in a largelaundry room, it can be expected to raise the temperatures within a laundry closet to levelsunacceptable for ordinary temperature rated sprinklers. All standalone ventless dryers in the marketare reportedly of this type.

Text for 6.2.3.3.3.1: This is language that is similar to NFPA 13 8.3.2.5 (9). In many places HVAC Airhandlers do not produce high temperatures. The ability to ignore the spacing away from thesediffusers simplifies the installation.

A.6.6.5 An example of an open or exterior 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).] Note that although NFPA 13R does not require sprinklers in corridors that are open and attached, the adopted building code might require sprinkler protection in certain open-ended corridors. The 2015 IBC has added section 903.3.1.2.2, which requires sprinklers in open-ended corridors and associated stairways that are not separated. This requirement has been included in 1027.6, but the ICC felt it needed to flag the requirement in NFPA 13R. As this committee did with the sprinklers on porches in buildings of Type 5 construction, it should align with what is found in the IBC. Figure A.6.6.5(a) Example of Open Corridor — Arrangement 1.

Committee Statement

CommitteeStatement:

The change reflects recent revisions made to NFPA 13D, Section 8.3.5.1, recognizing that fuel-firedequipment in attics is not uniquely hazardous to warrant the complexity of having to install a singlesprinkler in an attic space that will often be required to be protected from freezing. Given thepending prohibition of anti-freeze systems, having to install a freeze-protected single sprinkler over afuel-fired appliance will become even more difficult in the future.

Section 6.6.6 and 6.6.6.1 require sprinklers in attics that are intended for living or storage purposesand for attics that contain fuel-fired equipment, and it is helpful to provide guidance on attic protectionin Chapter 7 to correlate. In addition, model building codes are adding requirements for some otherattics to be protected with sprinklers or other acceptable means for protection of concealed spaces. Itis important for NFPA 13R to provide guidance on protection of attics for these situations as well. Theproposal parallels the design guidance for garages by offering an option to use not less than a 0.05gpm/sqft density and not less than a 4 sprinkler design basis. However, the minimum density and

A.7.4.3 NFPA 13R does not require installation of sprinklers in attics that are not intended for occupancy or storage. However, model building codes sometimes require protection of attics in tall, combustible-framed residential occupancies that are otherwise allowed to follow NFPA 13R. Such protection is permitted to be provided by sprinklers or other means allowed by the model building code or NFPA 13, as specified for protection of combustible concealed spaces. Common methods of protection in lieu of sprinklers include filling the space with noncombustible insulation, using fire-retardant-treated wood, or using noncombustible materials. Even though sprinklers are not mandatory for attic protection under NFPA 13R, NFPA 13R offers appropriate design requirements for cases where sprinklers are provided and sets design benchmarks that parallel what is permitted for garages.

A.9.4.2 The connection to city mains for fire protection is often subject to local regulation of metering and backflow prevention requirements. Where connections are made from public waterworks systems, such systems should be guarded against possible contamination per AWWA M14, Recommended Practice for Backflow Prevention and Cross Connection Control.

A.9.5.1 Preferred and acceptable water supply arrangements are shown in Figure A.9.5.1(a), Figure A.9.5.1(b), and Figure A.9.5.1(c). Where it is necessary to use a meter between the city water main and the sprinkler system supply, an acceptable arrangement as shown in Figure A.9.5.1(c) can be used. Under these circumstances, the flow characteristics of the meter are to be included in the hydraulic calculation of the system. Where a tank is used for both domestic and fire protection purposes, a low-water alarm that actuates when the water level falls below 110 percent of the minimum quantity specified in Section 9.2 should be provided. Pumps that are owned and operated by a public or private waterworks utility are not required to meet NFPA 20 because the waterworks industry standards for reliability and redundancy take care of concerns regarding reliability for fire-fighting operations. If there is any concern over the use of these non–NFPA 20 pump installations, then the waterworks would not be considered reliable and would not be permitted as a water supply. An authority having jurisdiction has the authority to review a combined domestic/fire protection pump arrangement and determine whether or not the reliability and redundancy meets the intent of NFPA 20, even if the exact arrangement of equipment does not meet the rules of NFPA 20.

It has become quite common to have four-story single-family dwellings and four-story townhomes,which the International Building Code requires sprinkler design in accordance with NFPA 13R inorder to have the fourth story. It becomes extremely expensive and over-burdensome for eachdwelling unit to have six spare sprinklers. From almost all aspects other than sprinkler hydraulicdesign, these dwellings are practically identical to homes protected by sprinkler systems designed byNFPA 13D, which requires no spare sprinklers. By minimizing the required number of sparesprinklers required for four-story single-family dwellings, the cost to the home buyers is therebyreduced.

NFPA 13R is appropriate for use as an alternative to NFPA 13 only in those residential occupancies, asdefined in this standard, up to and including four aboveground stories in height., and limited to buildingsthat are It should be noted that model building codes contain special allowances for pedestal orpodium-style buildings, which permit the story height for structures above the pedestal to be measuredfrom the top surface of the pedestal, rather than from grade plane, and it is the intent of NFPA 13R tofollow this model building code method for determining the number of stories. Accordingly, it is possiblefor a four-story residential structure to be within the scope of NFPA 13R even when that structure isconstructed on top of a one-story pedestal. However, where this is allowed, model building codes willrequire the pedestal portion to be constructed using Type I construction, and the pedestal portion will berequired to be protected by an NFPA 13–compliant sprinkler system.

Regardless of whether a building does or does not involve a pedestal, NFPA 13R systems are alwayslimited to structures that do not exceed 60 ft (18 m) or less in height above grade plane, which is . Notethat model building codes do not allow building height to be measured from the top of a pedestal. Thatallowance only applies to determining the number of stories. The 60-foot overall height limit is consistentwith limits established by model building codes for buildings of Type V construction. The height of abuilding structure above grade plane is determined by model building codes, which base the height on theaverage height of the highest roof surface above grade plane. For further information on the buildingheight story limits, see model building codes.

Buildings that contain multiple occupancies (either separated or nonseparated), accessory occupancies,or incidental uses are often subject to special rules that may might restrict the use of NFPA 13R. Refer tothe adopted building code to determine whether such restrictions are applicable.

The criteria in this standard are based on full-scale fire tests of rooms containing typical furnishings foundin residential living rooms, kitchens, and bedrooms. The furnishings were arranged as typically found indwelling units in a manner similar to that shown in Figure A.1.1(a), Figure A.1.1(b), and Figure A.1.1(c) .Sixty full-scale fire tests were conducted in a two-story dwelling in Los Angeles, California, and 16 testswere conducted in a 14 ft (4.3 m) wide mobile home in Charlotte, North Carolina. Sprinkler systemsdesigned and installed according to this standard are expected to prevent flashover within thecompartment of origin where sprinklers are installed in the compartment. A sprinkler system designed andinstalled according to this standard cannot, however, be expected to completely control a fire involving fuelloads that are significantly higher than average for dwelling units [10 lb/ft2 (49 kg/m2)], configurations offuels other than those with typical residential occupancies, or conditions where the interior finish has anunusually high flame spread index (i.e., greater than 225).

To be effective, sprinkler systems installed in accordance with this standard need to open the sprinklersclosest to the fire before the fire exceeds the ability of the sprinkler discharge to extinguish or control thefire. Conditions that allow the fire to grow beyond that point before sprinkler activation or that interfere withthe quality of water distribution can produce conditions beyond the capabilities of the sprinkler systemdescribed in this standard. Unusually high ceilings or ceiling configurations that tend to divert the rising hotgases from sprinkler locations or change the sprinkler discharge pattern from its standard pattern canproduce fire conditions that cannot be extinguished or controlled by the systems described in thisstandard.

NFPA 13R references NFPA 13 in many aspects (i.e., hanging and bracing, design densities and spacingoutside of dwelling unit, painting and finish of sprinklers, welding, etc. and so on ). If this standard does notspecifically address a situation, NFPA 13 is a good resource that can be utilized by the installer and theauthority having jurisdiction for a solution. It is not the intent of this standard to require compliance withNFPA 13 when NFPA 13R is silent on a subject. Only AHJ approval should be required.

Various levels of sprinkler protection are available to provide life safety and property protection. Thisstandard is designed to provide a high, but not absolute, level of life safety and a lesser level of propertyprotection. Greater protection to both life and property could be achieved by sprinklering all areas inaccordance with NFPA 13 , which permits the use of residential sprinklers in residential areas. both lifesafety and property protection, but to a lesser degree than would be achieved by using NFPA 13 .

This standard recommends, but does not require, sprinklering of all areas in the building; it permitssprinklers to be omitted in certain areas. These areas have been proved by NFPA statistics to be thosewhere the incidence of life loss from fires in residential occupancies is low. Such an approach provides areasonable degree of fire safety. (See Table A.1.2 for deaths and injuries in multifamily residentialbuildings.)

It should be recognized that the omission of sprinklers from certain areas could result in the developmentof untenable conditions in adjacent spaces. Where evacuation times could be delayed, additional sprinklerprotection and other fire protection features, such as detection and compartmentation, could benecessary.

Committee Statement

CommitteeStatement:

Clarification of intent. NFPA 13R is both a life-safety and property-protection standard. It isrecognized for property protection by model building codes, which grant construction incentives tobuildings protected by NFPA 13R systems, and sprinklers required for protection of balconies andgarages are primarily provided for property protection. Certainly, NFPA 13 provides an increasedlevel of protection for both life-safety and property protection, and the proposed revision makes thisclear.

First Revision No. 33-NFPA 13R-2016 [ Section No. A.3.3.1 ]

A.3.3.1 Bathroom.

A room is still considered a bathroom if it contains just a toilet. Additionally, two bathrooms can be that areadjacent to each other and are considered separate rooms, provided they are enclosed with the requiredlevel of construction. .



Committee Statement

CommitteeStatement:

The requirement that the bathrooms "are enclosed with the required level of construction" shouldbe removed as the 20 minute thermal barrier behind fixtures was no longer required beginning inthe 2007 NFPA 13R. As long as each adjacent bathroom meets the definition of a bathroom, theyshould be considered separate rooms.

A.6.6.6

Concealed spaces are permitted to have small openings such as grilles for return air when the space isbeing used as a plenum. Such small openings do not disqualify the space from being considered as aconcealed space, and sprinklers are still permitted to be omitted. (See Section 7.5 for additionalinformation on attic sprinklers.)

These connections should be installed so that the valve can be opened fully and for a sufficient timeperiod to ensure a proper test without causing water damage. The drain should be designed and sized toverify the sufficiency of the water supply.



Committee Statement

CommitteeStatement:

The purpose of the test connection is to verify that the water flow device is in proper workingorder. The way to verify the sufficiency of the water supply is to conduct a water flow test, notrunning water through the test connection.

A.7.1.1.3

All residential sprinklers have been investigated under a flat, smooth, 8 ft (2.44 m) high horizontal ceiling.Some residential sprinklers have been investigated and listed for use under specific ceiling configurationssuch as a horizontal beamed ceiling. The performance of residential sprinklers under flat, smooth,horizontal ceilings has been well documented throughout the life of NFPA 13R. Prior to 2010, severalmanufacturers of residential sprinklers had performed testing and received listings for residentialsprinklers under certain slopes and in certain beam conditions. In 2010, the Fire Protection ResearchFoundation (FPRF) conducted a research project consisting of 76 FDS simulations and 12 full-scale firetests. The results have been used to develop system design criteria in a generic manner in order tosimplify the use of residential sprinklers. Some residential sprinkler listings still exist for situations beyondthe scope of the generic design. ( See the FPRF report, “Analysis of the Performance of ResidentialSprinkler Systems with Sloped or Sloped and Beamed Ceilings,” dated July 2010, for more information.)

For examples of selecting a compartment for consideration, see Figure A.7.1.1.3(a) and FigureA.7.1.1.3(b), which show examples of design configurations for compartments based on the presence oflintels to stop the flow of heat.

Committee Statement

CommitteeStatement:

NFPA 13R, 2016 Figure A.7.1.1.3(b) depicts a minimum 8" lintel between the Dining Room andLiving Room. The 8" lintel alone does not meet the compartment definition which requires that theopening is limited to 8' width on any wall. Figure A.7.1.1.3(b) should be modified to depict amaximum 8' opening per the definition of a compartment found in NFPA 13R section 3.3.2.

A.7.3.4

Garages serving a single dwelling unit include garages that are directly connected to the dwelling unit andgarages that are served by a common corridor with access limited to a single owner or tenant.

Residential sprinklers and quick-response sprinklers at 0.05 gpm/ft2 (2.04 L/min/m2) densities have notbeen tested for use in garages. However, field experience has shown that they will activate, sound analarm, and provide water distribution that will assist in controlling a fire.



Committee Statement

Committee Statement: The fuel load/fire threat is effectively the same as that of an attached garage.Response Message:
