(2) The requirements of 11.1.2 (1) shall not apply where the areas are separated by a barrier partition that is capable of preventing delayingheat from a fire in one area from fusing sprinklers in the adjacent area.

(3) The requirements of 11.1.2 (1) shall not apply to the extension of more demanding criteria from an upper ceiling level to beneath a lowerceiling level where the difference in height between the ceiling levels is at least 2 ft (0.6 m).


The terminology between sections 11.1.2(1) and 11.1.2(2) needs to be consistent. One currently uses the terminology "delay" while the other uses the term "prevent". Since "prevent" has a more permanent connotation, its use here is inappropriate. All we are trying to do is delay the operation of sprinklers in the remote area until sprinklers over the fire have had a chance to open.

NOTE: This proposal appeared as Comment 24-1 (Log #3) which was held from theA12 ROC on Proposal 24-4.

Do not take the action in Proposal 24-4. Instead, revise section 5.1.3 and insert an annexnote as follows: 5.1.3* Where the volume and pressure available from a water supply are determinedthrough a waterflow test, an adjustment shall be made to the test data to account for dailyand seasonal fluctuations. A.5.1.3 Flow tests that are run during the middle of a business day often do not accountfor peak water demands at other times of the day or water use during other times of year. Under ideal circumstances, NFPA 24 would have a specific value to apply to all situations,but that is not practical given the wide variations of water supplies in use and thevariations of when waterflow tests are conducted. Waterflow tests conducted close topeak water usage times would need less of an adjustment than waterflow tests conductedduring low water usage times. Consultation with the water authority may be necessary todetermine an appropriate adjustment factor. Use of 24 hour gages at a hydrant can behelpful in determining day to day fluctuations. In addition, the user should also considerother water usage factors such as simultaneous industrial use, the potential for futuredemand on the system in the area of the test (depending on how well developed the areaalready is) and other conditions that would affect the water supply.



Open 24_PI_56_Held_Comment_24-1_Kelly_.pdf Held Comment 24-1


While some of the material currently in section 5.1.3 is more appropriate in the annex, the basic concept of requiring some adjustment to the data is still needed in the body of the standard. It is completely irresponsible to conduct a waterflow test at a hydrant at a time of very low water


http://submittals.nfpa.org/TerraViewWeb/XmlImageManager?objId=/TerraView/Content/24-2013.ditamap/2/C1369323440256.xml:=root&imageId=24_PI_56_Held_Comment_24-1_Kelly_.G1369323599553.pdf&altImageId=G1369323599553



demand and believe that you are going to have all of that flow and pressure available when a fire occurs a few hours later during a regular and known peak demand time. As proposed, the rule would only apply in those situations where the waterflow test is being performed and would not apply to the development of water supply data from other sources. The concept of evaluating the water supply for possible interruptions from flood or ice conditions has been intentionally dropped from the language because this does not have to do with the flow or pressure available. This concept should be a part of the determination as to whether the water supply is “reliable” enough to use at all, which is a completely different concept and should not be tied to evaluating data from a flow test.

5.2.1 Private Fire Service Mains.

Pipe smaller than 6 in. (152 mm) in diameter shall not be installed as a privateservice main supplying hydrants. A minimum 8 in. (203.2mm) diameter pipeshall be utilized for systems supplying multiple fire hydrants unless it canbe demonstrated that a smaller main will provide the proposed and futuredevelopment with adequate pressure and fire-flow.


Makes this standard compatible with AWWA and other regional standards. Fire hydrants should only be connected to water mains adequately sized to carry necessary fire flows. Private fire service mains that serve residential, industrial, or commercial developments may require larger mains to assure adequate pressure and fire-flow for current and future development needs.

5.9.1.4

Fire department connections shall be equipped with listed plugs or caps that aresecured and arranged for easy removal by fire departments.





There is no need to utilize listed plugs or caps for a fire department connection. Often, the nice new brass ones that come with a listed FDC go missing and have to be replaced. To avoid repetitions of such losses, one option that building owners may choose is to replace them with vandal resistant “break away” or “knock off” caps, which are economical, unattractive to brass scavengers and they generally make poor ash trays. These devices are not usually listed and they do not need to be, because components such as FDC caps and plugs do not affect system performance.





















5.9.1.6 The AHJ shall have the authority to require locking fire departmentconnection ( FDC ) plugs or caps on all water-based fire protection systems. (1:13)


Makes this standard compatible with NFPA 1 Chapter 13 and gives AHJ's the ability to require locking caps for FDC’s on private water systems where jurisdictions do not utilize NFPA 1.

5.9.4.2.1

The automatic drip shall be permitted to be buried where permitted by the authority havingjurisdiction.

5.9.4.2.2

Where the automatic drip is buried as allowed by 5.9.4.2.1, the outlet shall discharge intoa bed of crushed stone or pea gravel.


The 2013 edition was modified to require access to the ball drip. Many AHJ's require that fire department connections (FDC) are remote. NFPA suggests that the check valve for the FDC be located as close to the connection to the system as possible. This could leave long sections of underground piping with no pressure. This piping could get cut and one will not know about it until an NFPA 25 inspection is performed or the fire department pumps into the connection. Many AHJ's want water brought as close to the FDC as possible to avoid this situation. By requiring access to the ball drip, this could require a vault or deep meter box costing hundreds of dollars. This new section gives the AHJ an allowance to require the automatic drip close to the FDC and still have water on the underground piping for supervision.





















5.9.4.3

An automatic drip shall not be required in areas where the piping is not subject tofreezing.


There are many areas in the country where the temperature of the air will dip below 32 degrees Fahrenheit but will never last long enough to freeze a 4" or 6" pipe. Technically this means that freezing has been achieved because water freezes at 32° FH. This change gives allowance for these climate areas.





















5.9.4.3

An automatic drip shall not be required in on fire department connections forsystems located in areas not subject to freezing.


As presently written, this requirement may be confused as to mean that the location of the automatic drip cannot be in an area where it would freeze. In actuality, the automatic drip is not required on any part of a system that is located in a geographical area that is not subject to freezing climates.

This is important information that should be located in this section. Renumber accordingly.





















5.9.5.1 *

Fire Remote fire department connections shall be located at the nearest point offire department apparatus accessibility or at a location approved by the authorityhaving jurisdiction.


the section needs to be specific in that it is referencing remote fire department connections. Fire department connections mounted on buildings are under the jurisdiction of NFPA 13. Identifying "remote" keeps the informatoin specific to remotely located hydrants.





















5.9.5.2 *

Fire Remote fire department connections shall be located and arranged so thathose lines can be attached to the inlets without interference.























5.9.5.3 *

Each fire remote fire department connection shall be designated by a sign asfollows:

(1) The sign shall have raised or engraved letters at least 1 in. (25.4 mm) inheight on a plate or fitting.

(2)


















* The sign shall indicate the type of system for which the connection isintended.






5.9.5.4

Where the system demand pressure exceeds 150 psi (10.3 bar), the sign requiredby 5.9.5.3 a sign located at the fire department connection shall indicate therequired design inlet pressure.


Almost all the fire department connection plates indicating the connection type (autosprinkler, standpipe or both) are bought directly from the fire department connection manufacturers. Engraving these with the required inlet pressure is impractical. Also, since the sign referred to requires one inch high letters, it could be construed that the pressure information should also be the same size. In the fire sprinkler business, when a higher pressure requirement must be posted, we have custom made signs produced and placed on or at the FDC.





















5.9.5.5

Where a fire remote fire department connection only supplies a portion(s) of thebuilding, a sign shall be attached to indicate the portion(s) of the building supplied.























6.1.1

All Except as permitted by 6.2.1, all valves controlling connections to watersupplies and to supply pipes to sprinklers water-based fire protection systemsshall be listed indicating valves.





During the previous revision cycle the words “listed indicating” were deleted from 6.2.1. This created a conflict whereby 6.1.1 and 6.2.5 call for listed indicating valves on water supplies, but 6.2.1 does not. The proposed text is offered as a resolution to this conflict. Additionally the modification to 6.2.1 would require the configuration to be acceptable to the AHJ and the proposed Annex text would offer an explanation for the matter.Also, in 6.1.1 the specific reference to “sprinklers” was revised to “water-based fire protection systems”, since private fire service mains supply other types of systems as well.























6.2.1.1 When more than one valve is installed in a water system, all valves shall be of thesame opening direction.


addresses the possibility of installing different opening direction valves in the same system by requiring that all valves be of the same operating characteristic

2006 Fire code section 508.5.6 states that hydrants subject to impact by motor vehicles, shall be provided with guard posts or other approved means that comply with section 312.

Section 312 states that the spacing between posts shall not exceed 4 (four) foot on center and not less than 3 (three) feet from protected object. The demensions stated have been investgated numerous times in the field to confirm that it is not possible to provide the protection required using 4 (four) posts.

Currently architects/designers are calling for the use of 4 posts, it is not possible to maintain the 4 foot on center between posts and the 3 foot clearance from the protected object without adding an additional post.

This concern is usually handled through the architect of record for the project, but it comes with a change order/additional cost to the owner.

13.2 Mains Not Supplying Hydrants.

For mains that do not supply hydrants, sizes smaller than 6 in. (152 mm) shall bepermitted to be used, subject to the following restrictions:

(a) Automatic sprinkler systems

(b) Open sprinkler systems

(c) Water spray fixed systems

(d) Foam systems

(e) Class II standpipe Standpipe systems

(2) Hydraulic calculations shall show that the main is able to supply the totaldemand at the appropriate pressure.

(3) Systems that are not hydraulically calculated shall have a main at least aslarge as the riser.





This change is proposed to align 13.2 (e) with the text of 5.2.2 (e), which was revised during the last cycle to delete the “Class II” reference. As discussed then, there should not be a requirement which specifies a 6” minimum water supply for all Class I & III standpipes. NFPA 14 requires that all new standpipes be hydraulically calculated, so this standard should not dictate a minimum size for the private fire service mains that supply them.

The figure needs to be revised. The pipe leading up to the transition to the riser does not need to be ductile iron. Any type of acceptable underground should be permitted. This is consistent with the change to NFPA 24 last cycle to allow up to 24 inches of pipe above ground to make the transition to the riser.

A.10.8.3

A method for providing thrust restraint is the use of restrained joints. A restrainedjoint is a special type of joint that is designed to provide longitudinal restraint.Restrained joint systems function in a manner similar to that of thrust blocks,insofar as the reaction of the entire restrained unit of piping with the soil balancesthe thrust forces.

The objective in designing a restrained joint thrust restraint system is to determinethe length of pipe that must be restrained on each side of the focus of the thrustforce. This will be a function of the pipe size, the internal pressure, the depth ofcover, and the characteristics of the solid surrounding the pipe.

3.3 General Definitions.

3.3.1 Rated Capacity.

The flow available from a hydrant at the designated residual pressure (ratedpressure), either measured or calculated.

3.3.2 Residual Pressure.

The pressure that exists in the distribution system, measured at the residualhydrant at the time the flow readings are taken at the flow hydrants.

3.3.3 Static Pressure.

The pressure that exists at a given point under normal distribution systemconditions measured at the residual hydrant with no hydrants flowing.

3.3.4 US National Grid

An alphanumeric point reference system that has been overlaid on the UniversalTransverse Mercator (UTM) numerical grid. Every modest size home in a discretearea (city) can be described using 8-digits (e.g., 1234 5678). By adding a two-letterprefix (e.g., XX 1234 5678) the location is uniquely identified regionally (state-wide).US National Grid is functionally identical to Military Grid Reference System(MGRS), used by US military and NATIO since 1949. In the case of hydrants, an8-digit coordinate would uniquely identify the location and it could be used tocalculate approximate distances, when necessary.


Defines what US National Grid is and how it can benefit hydrant location information.

Annex A Explanatory Material

Annex A is not a part of the recommendations of this NFPA document but isincluded for informational purposes only. This annex contains explanatory material,numbered to correspond with the applicable text paragraphs.

A.3.2.1 Authority Having Jurisdiction (AHJ).

The phrase “authority having jurisdiction,” or its acronym AHJ, is used in NFPAdocuments in a broad manner, since jurisdictions and approval agencies vary, asdo their responsibilities. Where public safety is primary, the authority havingjurisdiction may be a federal, state, local, or other regional department or individualsuch as a fire chief; fire marshal; chief of a fire prevention bureau, labor department,or health department; building official; electrical inspector; or others havingstatutory authority. For insurance purposes, an insurance inspection department,rating bureau, or other insurance company representative may be the authorityhaving jurisdiction. In many circumstances, the property owner or his or herdesignated agent assumes the role of the authority having jurisdiction; atgovernment installations, the commanding officer or departmental official may bethe authority having jurisdiction.

A.3.2.2 Listed.

The means for identifying listed equipment may vary for each organizationconcerned with product evaluation; some organizations do not recognize equipmentas listed unless it is also labeled. The authority having jurisdiction should utilize thesystem employed by the listing organization to identify a listed product.

A.4. 11.2

Consider US National Grid coordinates for Location of hydrants, in additionto any other standard description. A coordinate to a precision of eightdigits equates to an area of 10 meters square (33' x 33'). In practically allcases, this will uniquely define the hydrant. Two oordinates can also beused for distance calculations between hydrants. Example: 17R NM 38774016

A.4. 13.1

When flow test data are needed, such data should not be more than 5 years oldsince conditions in the piping and system demands can change. It is not the intentof 4.13.1 to require routine 5-year testing of each hydrant if there is no immediateneed for flow test data or if test data less than 5 years old are available from anadjacent hydrant on the same grid.





The preferred coordinate system designed for land based operations is US National Grid. It is the standard for Florida, Minnesota, FEMA, DHS, etc.and is effectively the same system used by the military since 1949. The system uses no decimals, degrees, minutes, seconds and is scalable. 3 digits equates to and area of 100 meters square and 4 digits equates to an area of 10 meters square (33 feet x 33 feet). Practically everywhere, there would be only one hydrant per 10 meter square. Using simple math the distance between hydrants can be determined. Example: Hydrant1 at 17R NM 3877 4015, Hydrant2 at 17R NM 3877 4034. If easting and northing were not the same, use Pythagoras's theorem. In this case easting is the same, 3877 - 3877 = 0, 4034 - 4015 = 19 (10s) or 190 meters. Conversion to feet is easily done. US National Grid is widely available in GPS and smart phone applications.. It can be in the hands of hydrant testers for no cost in most cases. http://www.fgdc.gov/usng http://www.mngeo.state.mn.us/committee/emprep/download/USNG/index.html Summary: a technical enhancement for location identification
