5 13R-1 Log #52 AUT-RSS Final Action: Accept in Principle (Entire Document) Submitter: Eddie Phillips, Southern Regional Fire Code Development Committee Recommendation: Reconsider the original proposal by either extracting the appropriate text from NFPA 13 or by the TC on Residential Sprinkler Systems writing their own text to address the deficiencies in the standard. If neither of these alternatives are acceptable to the TC at the ROC phase, we suggest creating a task group to reconsider this issue and appropriate text for the next edition of. Substantiation: The original proponent s proposal has compelling and technically correct substantiation. These issues do need to be addressed within to eliminate interpretation conflicts where there is no code on the topic. However, we also strongly concur with Mr. L. Brown s comment on the affirmative that any additional language must be maintained in so it can continue to be a stand alone document. A straight reference to NFPA 13 is not appropriate for this standard. No action on this log required. However, each item was addressed in separate ROC logs. Committee Statement: See each ROC log that addresses these concerns. 13R-2 Log #CC2 AUT-RSS Final Action: Accept (Entire Document) Submitter: Technical Committee on Residential Sprinkler Systems, Recommendation: Where text was accepted from NFPA 13 ensure that the requirements are consistent with the final text of NFPA 13. Substantiation: The committee wants to ensure that where they copied requirements from NFPA 13 that the requirements remain consistent with the new text. 13R-3 Log #CC3 AUT-RSS Final Action: Accept (Entire Document) Submitter: Technical Committee on Residential Sprinkler Systems, Comment on Proposal No: 13R-3a Recommendation: The committee tasks staff to editorially modify all accepted changes to ensure consistency with other accepted changes and to ensure compliance with the NFPA manual of style. Substantiation: The committee wants to ensure that the final text of is consistent with the committee s intent while complying with the NFPA Manual of Style. 13R-4 Log #6 AUT-RSS Final Action: Accept (1.1) Comment on Proposal No: 13R-6 Recommendation: Reject proposal 13R-6. Substantiation: The definition is not compatible with the building codes and will cause more problems than it solves. Building codes each define story in their own way and should be compatible with all of them. This will mean that the same exact building might not be able to be built in every jurisdiction, but that is the nature of local building codes. This comment is being submitted on behalf of the NFSA Engineering and Standards Committee. Requirement(s) of published Committee Approved change deleted without opportunity for Public Comment. 13R-5 13R-5 Log #47 AUT-RSS Final Action: Reject (1.1) Submitter: Maurice M. Pilette, Mechanical Designs Ltd. Recommendation: Change 1.1 to read as follows: 1.1 Scope. This standard shall cover the design and installation of automatic sprinkler systems for protection against fire hazards in buildings of residential occupancies up to and including four stories in height above and below the building s grade plane as defined and adopted by the applicable building code of the authority having jurisdiction. A.1.1 is This standard is appropriate for use as an option to NFPA 13, Standard for the Installation of Sprinkler Systems, only in those residential occupancies, as defined in this standard, up to and including four stories. in height. It is the intent of this standard that if is appropriate for use, that it be used throughout the entire building. It is recognized that an occupancy incidental to the operations of the residential occupancy might exist within that residential occupancy. Such incidental occupancy would be considered part of the predominant (residential) occupancy and subject to the provisions of the predominant (residential) occupancy by of NFPA 101, Life Safety Code, and similar provisions in many local building and fire codes adopted applicable codes of the authority having jurisdiction. Use of this standard throughout the entire building in this case is allowed shall be permitted. Where buildings are greater than four stories in height, or where buildings are of mixed use where residential is not the predominant occupancy, residential portions of such buildings should shall be protected with residential or quick-response sprinklers in accordance with of NFPA 13. Other portions of such buildings should shall be protected in accordance with NFPA 13. Where buildings of mixed use can be totally separated so that the residential portion is considered a separate building under the local codes adopted applicable codes of the authority having jurisdiction, can be used in the residential portion, while NFPA 13 is used in the rest of the building. Some of the above language has been taken from A.1.1 and modified to be included in the expanded language of 1.1 Scope of this standard, therefore: The entire first two paragraphs noted in A.1.1 commencing with the words A.1.1 is appropriate... in the first paragraph and ending in the second paragraph with the word building to be removed. The remaining two paragraphs commencing with the words The criteria in this standard... and ending in the last with the word standard to remain as is. Substantiation: Better defines the Committee s intent of the applicable use of as originally proposed and developed and first published in Development and construction of residential buildings for which applies are being constructed significantly different than originally envisioned such as construction on sloping grades, one or more levels below grade, mixed use occupancies (parking garage, mercantile, etc., below residential occupancies), with inadequate fire separation to be considered a separate building under the local building and fire codes. The addition of the language to further defines four stories in height above and below the building s grade plane as defined and adopted by the applicable building code of the authority having jurisdiction provides additional clarification and consistence with building codes. Committee Statement: See committee action and statement on Comment 13R-4 (Log #6). 13R-6 Log #49 AUT-RSS Final Action: Reject (1.1) Submitter: Rodney A. McPhee, Canadian Wood Council Comment on Proposal No: 13R-6 Recommendation: Do not adopt the new wording and instead revise 1.1 to read in part:...up to and including four stories in building height. Add new text in the Appendix note to read: A.1.1 The building height of the building in stories is determined in accordance with the applicable local building code. Substantiation: Different codes may use different reference points or terminology when determining the building height in stories. To avoid confusion, it is more appropriate to keep the requirement generic and give guidance in the Appendix as to the intent.

6 Committee Statement: See committee action and statement on Comment 13R-4 (Log #6). split be considered as ground floors, and thus requiring accessible exits on both levels, have increased the buildings safety for all occupants. It should also be noted that the proposed wording basing the height allowed on fire department access, although more restrictive, would also under certain circumstances allow the 4/5 split. The proposed change will adversely affect the apartment industry s ability to provide affordable housing.

(1.1) NMHC/NAA estimates it will cost at minimum $1,800 per apartment Submitter: Lawrence Brown, National Association of Home Builders Comment on Proposal No: 13R-6 Recommendation: Do not accept proposed change. Substantiation: From all of the documentation available on the reason for the four story height has nothing to do with the level of fire department vehicle access. All one need to do is read the Annex material on this Section to understand the intent of this wording. As this is the case no change is need to this provision. unit ($1.75 to $2.00 per square foot) to implement this change, adding unnecessarily to the cost of construction which ultimately is passed onto the consumer. Following are the requirements from the various codes and standards concerning the height for application of the sprinkler system. NFPA 5000: Section Where an automatic sprinkler system is installed, either for total or partial building coverage, the system shall be in accordance with Section 13.3, as modified by ; in buildings up to and including four stories in height above grade, systems in accordance with, Standard for the Installation of Sprinkler Systems in Residential Occupancies up to and Including Four Stories in Height, shall be permitted. [101: ] NFPA 101: Section Where an automatic sprinkler system is installed, 13R-8 Log #2 AUT-RSS Final Action: Accept in Principle either for total or partial building coverage, the system shall be installed (1.1 Scope) in accordance with Section 9.7, as modified by and In Submitter: Ronald G. Nickson, National Multi Housing Council & Schwartz Fire Specialists Comment on Proposal No: 13R-6 Recommendation: Revise text as Follows: 1.1 Scope. This standard shall cover the design and installation of automatic sprinkler systems for protection against fire hazards in residential occupancies up to and including four stories in height above the lowest level of fire department vehicle access building grade plane. Or, delete the new phrase in height above the lowest level of fire department vehicle access and leave the section as currently written in the 2002 edition. Substantiation: The added wording above the lowest level of fire department vehicle access should be revised to above the building grade plane, to reflect current code provisions, or removed leaving the section as it is in the 2002 Edition of NFPA13R. The proposed wording to establish the bases for height limitation for the sprinkler systems based on the lowest level of fire department vehicle access conflicts with the provisions of NFPA 5000, NFPA 101, the NFPA Automatic Sprinkler System Handbook, and locally adopted codes based on the International Building Code. In addition, it does not agree with past NFPA staff and other code organizations interpretations (copies attached), accepted practices, and the historical applications permitted by the building codes which have based the height upon the building grade plane. The proposed restriction to base the height allowed for application of the sprinkler systems on the height above the lowest level of fire department vehicle access was done without any supporting documentation to show that there is any safety problem or a need to restrict the use of systems beyond what is allowed by NFPA 5000, NFPA 101, the NFPA Automatic Sprinkler System Handbook, or local codes which uniformly set the allowable height based on the building grade plane. There is also no justification for establishing a different base for height determination for sprinkler system than what is used for all other applications in the above reference documents. In fact, quite the opposite is true as documented by NFPA fire data and information on performance of sprinkler systems. The data clearly shows that sprinkler systems are performing Ð they are saving lives and reducing property losses Ð with apartments, hotels, and motels (places where systems are typically used) being listed among the occupancies with the highest percentage of operation success. According to the NFPA data, 94% of the fires in sprinkler apartments and 96% of the fires in sprinkler hotels and motels are confined to the room of origin. NFPA also has no record of a fire killing more than two people in a completely sprinklered residential building where the system was properly operating. Buildings with 13R sprinkler systems have an outstanding fire history best documented by Operation Live Safety (OLS). During the time in which OLS tracked fires in buildings with sprinkler systems, OLS reported that there were no deaths in the properties reported. OLS further concluded that there are no safety issues or concerns related to the use of the sprinkler system. Using the grade plane as a reference for the height does allow the typical 4/5 split apartment to be sprinklered with an sprinkler system. This however, does not have any impact on the safety of the building occupants or the ability of the occupants to egress the building in an emergency because of the code requirements for exits and egress openings. New provisions in the codes requiring that both levels in a 4/5 buildings up to and including four stories in height above grade, systems in accordance with, Standard for the Installation of Sprinkler Systems in Residential Occupancies up to and Including Four Stories in Height, shall be permitted. NFPA Sprinkler Handbook: Question: Does define the height of a story or the total height of a building? Response: does not define the height of a story for use in determining overall building height. The building height is anticipated to be determined in accordance with the applicable building code (e.g. NFPA 5000, Building Construction and Safety Code) or NFPA 101 Life Safety Code, each of which have their own method for determining building and story heights. International Building Code: Height determination and number of stories allowed with the installation of a sprinkler system was an issue brought forward in the ICC codes, due to changes in the definition of story when the three model codes were combined into a single code. The change to the definition of story was made without consideration of the implication on the application of the sprinkler system. As a result of that change and the resulting confusion ICC has issued the following official interpretation concerning the height application for sprinkler system. In addition, the IBC Code Development Committee has recommended for approval changes to the code specifically establishing that for the application of the sprinkler system the height is to be based on the building grade plane. It should also be noted that the building codes (NFPA 5000 and IBC) also include, in addition to the story limitation, a limitation on the total overall height of a building protected with a NFPA 13R sprinkler system. The IBC has other special provisions concerning the use of 13R sprinklers in buildings with mixed occupancies. ICC Official Interpretation: Question: Is an sprinkler system permitted in a Group R occupancy where four stories of the building are located above grade plane and one story is located below grade plane? Answer: Yes. The definition of Building Height Ð the vertical distance from grade plane to the average height of the highest roof surface Ð establishes the grade plane as the reference point for determining building height and number of stories. Section 503 and Table 503 establish the maximum building height and number of stories permitted for all occupancies above the grade plane. The maximum number of stories and building height in Table 503 can be modified as permitted by Section 504.2, Automatic sprinkler increases, when a sprinkler system is installed throughout in accordance with. With the modification in Section the building above the grade plane can be four stories provided the overall building height does not exceed 60 feet, measured to the average height of the highest roof surface. The type of occupancy permitted in the basement, including residential, is not controlled by the Code provided the basement is separated from the residential portions of the building in accordance with the mixed-use provisions of the Code. S- 2 occupancies can also be installed in the lower level of an R occupancy if they comply with the requirements of Section 508. The lower level, or basement, of the building must comply with the Code definition for basement. Note: Supporting material is available for review at NFPA Headquarters.

7 13R-9 Log #55 AUT-RSS Final Action: Reject (1.1.2) Submitter: Richard Pehrson, Futrell Fire Consult & Design Comment on Proposal No: 13R-7 Recommendation: Revise text to read: A building provided with a fire sprinkler system designed and installed in accordance with the requirements of this standard, including its allowable omissions, shall be considered fully sprinklered throughout for life safety purposes, but not property protection. Substantiation: The scope of is to provide for life safety, not the complete level of property protection afforded by NFPA 13. As long as all occupants successfully exit a building on fire protected with an system, the performance would be a success, even if the entire building burned to the ground. It is becoming more difficult to explain this situation to the public as to why a sprinklered building was destroyed by fire. To characterize a building protected with a system as fully sprinklered, which it clearly is not, will do more harm than good in the long run. This issue should be addressed in the building and fire codes, not. Committee Statement: The standard does provide certain level of property protection and the proposed statement is incorrect. 13R-10 Log #4 AUT-RSS Final Action: Reject (1.1.2 and 4.1) Submitter: Ivan J. Humberson, City of Gaithersburg, MD Comment on Proposal No: 13R-7 Recommendation: Change the action on this proposal to reject. Substantiation: The determination as to what constitutes fully sprinklered should not be part of the installation standard. The Building Code or Life Safety Code should specify which standard the system installation must comply with in order for the building to be considered fully sprinklered. For example, the International Building Code only allows area increases for buildings protected in accordance with NFPA 13, but allows height increases for residential buildings protected in accordance with or NFPA 13. The Building Code or Life Safety Code should specify which standard to use, and the installation standard should be limited to how the installation must be accomplished. Committee Statement: It is within the scope of this document to determine what requirements will determine fully sprinklered for buildings within the scope of this document. Use of the term fully sprinklered is applicable to the use and application of. 13R-11 Log #11 AUT-RSS Final Action: Reject ( ) Comment on Proposal No: 13R-53 Recommendation: Delete all of 13R-53 and insert a new section as follows: Sprinklers shall not be required for skylights not exceeding 32 sq ft, which shall be permitted to have a plastic cover. Substantiation: There is no substantiation for the 100 cubic foot pocket. Serious delays can occur that will affect the ability of the sprinkler to maintain reasonable conditions in the room of fire origin. Residential sprinklers are very different than other sprinklers and parallels from other standards are not necessarily adequate. The skylight provision is permitted in NFPA 13 for residential sprinklers and is reasonable given the limitation on the area of the pocket. With a maximum of 32 sq ft in area, all of the hot gasses from the fire should not go up in the pocket and the sprinkler might react in a reasonable time. It would be nice to have some data to back up the assumption. This comment is being submitted on behalf of the NFSA Engineering and Standards Committee. Committee Statement: The committee continues to support the position established in the Report on Proposals. It is the intent of the committee that the smaller permitted volume addresses the concerns raised about the difference between NFPA 13 and. 13R-7 13R-12 Log #50 AUT-RSS Final Action: Reject (Chapter 3) Submitter: Robert Bourke, Northeastern Regional Fire Code Dev.

The portion of a building located between the upper surface of a floor and the upper surface of the floor or roof next above. (5000: ) Substantiation: There needs to be better clarification on when the standard applies and the addition of the definition of story from NFPA 5000 will assist the user of the document. Leaving it up to the building code in the area provides misapplication of the standard. The proposed text accepted by the committee in the proposal actually increases the height of most buildings further confusing the issue.

Ordinary hazard (Group 1) occupancies shall be defined as occupancies or portions of other occupancies where combustibility is low, quantity of combustibles is moderate, stockpiles of combustibles do not exceed 8 ft (2.4 m), and fires with moderate rates of heat release are expected Ordinary Hazard (Group 2). Ordinary hazard (Group 2) occupancies shall be defined as occupancies or portions of other occupancies where the quantity and combustibility of contents are moderate to high, stockpiles do not exceed 12 ft (3.7 m), and fires with moderate to high rates of heat release are expected. Annex: A Light hazard occupancies include occupancies having uses and conditions similar to the following: Churches, Clubs, Eaves and overhangs, if of combustible construction with no combustibles beneath, Educational, Hospitals, Institutional, Libraries, except large stack rooms, Museums, Nursing or convalescent homes, Offices, including data processing, Residential, Restaurant seating areas, Theaters and auditoriums, excluding stages and prosceniums, and Unused attics. A Ordinary hazard occupancies (Group 1) include occupancies having uses and conditions similar to the following: Automobile parking and showrooms, Bakeries, Beverage manufacturing, Canneries, Dairy products manufacturing and processing, Electronic plants, Glass and glass products manufacturing, Laundries, and Restaurant service areas A Ordinary hazard occupancies (Group 2) include occupancies having uses and conditions similar to the following: Dry cleaners, Horse stables, Libraries Ñ large stack room areas, Mercantile, Post offices, Repair garages, and Stages. Substantiation: The terms are used throughout and need to be defined here if we are not going to refer to NFPA 13. The text here was taken from Sections 5.2 and 5.3 of NFPA 13 and modified by dropping those annex examples that are not appropriate for occupancies. Insert new definitions and annex text as follows: Hazard Classifications Light Hazard Occupancy: Light hazard occupancies shall be defined as occupancies or portions of other occupancies where the quantity and/or combustibility of contents is low and fires with relatively low rates of heat release are expected Ordinary Hazard (Group 1).

Committee Statement: The committee agreed with the submitter, but wanted to further clarify the text as it applies to. Ballot Results: Affirmative: 23 Negative: 1 Explanation of Negative: BENN, F.: This committee statement does not state what changes would be made to this proposal. A large number of items in this proposal are not applicable to systems. BROWN, L.: NAHB is somewhat in agreement with the Ballot Comment by Mr. Benn. In addition, it would seem the standard would be more user-friendly if it contained only the provisions necessary to install the most widely used type of system in low-rise residential buildings. Provisions for installation criteria that is not normally used in low-rise residential construction should only be by a reference to NFPA 13. If these rarely used systems are installed the installer would most likely already be familiar with the provisions of NFPA 13. Although NAHB votes Affirmative with the Committee Action, NAHB believes this is a Substantive Change as defined in the ANSI Essential Requirements. Thus, in accordance with the ANSI Essential Requirements Section 2.4, this Substantive Change is required to be listed in Standards Action in order to provide an opportunity for public comment. In addition, in accordance with ANSI Essential Requirements Section 2.5, this TC shall consider all written views and objections as a result of the public comment listing in Standards Action. Type of ANSI Substantive Change: Addition, Deletion or Revision of Requirements, i.e., New requirement(s) added without opportunity for Public Comment (Comment based on published Proposal that was Rejected). 13R-14 Log #7 AUT-RSS Final Action: Accept in Principle (4.1.2) Comment on Proposal No: 13R-13 Recommendation: Revise the 6 ft width to 7 ft. Substantiation: The intent was to allow double doors. At the time of the ROP meeting we thought that a 6 ft width would accommodate such doors, but upon further review, we find that 7 ft might be more realistic for many double door combinations. This comment is being submitted on behalf of the NFSA Engineering and Standards Committee. See committee action and statement on Comment 13R-15 (Log #58).

A space completely enclosed by walls and a ceiling. The compartment enclosure is permitted to have openings in walls to an adjoining space if the openings have a minimum lintel depth of 8 in. (203 mm) from the ceiling and the openings do not exceed 8 6 ft in width. Substantiation: Changing the dimension to 8 feet from 6 feet should pose no problem in relationship to the concern outlined in the Submitter s Substantiation. The 8-foot dimension is more applicable to the nominal opening between adjoining rooms found in the field. Also, one would be hard-presses to raise this concern as shown in the Submitter s Substantiation as a room only 8 feet wide would probably not be considered the largest room of a dwelling in relationship to avoiding the four-head calculation. Requirement(s) of published Committee Approved change revised without opportunity for Public Comment. 13R-8 13R-16 Log #36 AUT-RSS Final Action: Accept (4.3) Recommendation: Add a new Section 4.3 as follows: 4.3* Basic Requirements * The requirements for spacing, location, and position of sprinklers shall be based on the following principles: (1) Sprinklers shall be installed throughout the premises. (2) Sprinklers shall be located so as not to exceed maximum protection area per sprinkler. (3) Sprinklers shall be positioned and located so as to provide satisfactory performance with respect to activation time and distribution. (4) Sprinklers shall be permitted to be omitted from areas specifically allowed by this standard (see Section 6.8). (5) When sprinklers are specifically tested and test results demonstrate that deviations from clearance requirements to structural members do not impair the ability of the sprinkler to control or suppress a fire, their positioning and locating in accordance with the test results shall be permitted. (6) Clearance between sprinklers and ceilings exceeding the maximums specified in this standard shall be permitted provided that tests or calculations demonstrate comparable sensitivity and performance of the sprinklers to those installed in conformance with these sections. Substantiation: This language is taken from Section 8.1 of NFPA 13 and modified to reference the correct section where sprinklers are permitted to be omitted (6.8). While it could be argued that Section 6.8 of already covers some of this material, much of it (using sprinklers within their protection area and allowing alternative placement when tests or calculations can show comparable performance) is only implied by the current wording in. More specific language is necessary for most AHJ s. Current requirement(s) revised and/or deleted and new requirement(s) added without opportunity for Public Comment (Comment based on published Proposal that was Rejected). 13R-17 Log #37 AUT-RSS Final Action: Accept in Principle (5.1.1) Recommendation: Add new subsections (and an annex note) to as follows: Unless the conditions of or exist, sprinklers shall be installed in accordance with their listing.
