PUBLIC INPUT

Public Input No. 492-NFPA 13-2013 [ Section No. 9.3.7.1 [Excluding any Sub-Sections] ]

Where seismic protection is provided, C-type clamps (including beam and large flange clamps) used to attach hangers to the building structure shall be equipped with a restraining strap unless the provisions of 9.3.7.1.1 are satisfied. C-type clamps with or without restraining straps shall not be used to attach hangers of any pipe for which lateral bracing has been omitted per the provisions of 9.3.5.5.10 or any pipe attached to that pipe.

Statement of Problem and Substantiation for Public Input

Where lateral bracing is omitted, piping will be subject to large and repeated lateral deflections that could damage or displace c-clamp hangers on the pipe for which the bracing is omitted or on the attached pipe (e.g., branch lines attached to a cross main).

10.8.3.4.1 Material selected shall be compatible with the piping material to be installed.


material compatibility is necessary to avoid potential electrolysis between dissimilar metals



Public Input No. 453-NFPA 13-2013 [ New Section after 10.10.2.4.1 ]

10.10.2.4.1.1 Opening and closing of hydrants shall be completed under both static pressure (no flow) and flow conditions.


by adding that the hydrant has to be operated under no flow and flow conditions, ensures proper operation of the hydrant




11.1.2* Adjacent Hazards or Design Methods. For buildings with two or more adjacent hazards or design methods, the following shall apply:

(1) Where areas are not physically separated by a barrier or partition capable of delaying heat from a fire in one

area from fusing sprinklers in the adjacent area, the required sprinkler protection for the more demanding design basis shall extend 15 ft (4.6 m) beyond its perimeter.

(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 delaying heat 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 lower ceiling 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.

PVC-O solves the problem of the low impact of PVC-U at low temperatures and the problem that PVC-u is more sensitive to water hammer. PVC-O is not. This type of pipe is in use all over the world, produced by a number of different companies and with a good track record. The pipe is in use since approx. 1990. Several of our customers have asked to use this pipe also for fire fighting lines, but it failes to be registered in NFPA24

NOTE: This proposal appeared as Comment 24-1 (Log #3) which was held from the A12 ROC on Proposal 24-4. Do not take the action in Proposal 24-4. Instead, revise section 5.1.3 and insert an annex note as follows:

5.1.3* Where the volume and pressure available from a water supply are determined through a waterflow test, an adjustment shall be made to the test data to account for daily and seasonal fluctuations.

A.5.1.3 Flow tests that are run during the middle of a business day often do not account for 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 the variations of when waterflow tests are conducted. Waterflow tests conducted close to peak water usage times would need less of an adjustment than waterflow tests conducted during low water usage times. Consultation with the water authority may be necessary to determine an appropriate adjustment factor. Use of 24 hour gages at a hydrant can be helpful in determining day to day fluctuations. In addition, the user should also consider other water usage factors such as simultaneous industrial use, the potential for future demand on the system in the area of the test (depending on how well developed the area already 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

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.

shall be utilized for systems supplying multiple fire hydrants unless it can

be demonstrated that a smaller main will provide the proposed and future

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 are secured 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 department

connection ( 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.

The use of the term "system piping" has caused confusion on just where a fire department connection (fdc) can be installed. They read this as meaning that you cannot have any shutoff valve between the fdc and the system sprinkler system.

The term "fire service main" is used in Figure A.5.9(b).

5.9.4.2.1

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

5.9.4.2.2

Where the automatic drip is buried as allowed by 5.9.4.2.1, the outlet shall discharge into a 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 to freezing.


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 for systems 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.

5.9.5.1 * Fire Remote fire department connections shall be located at the nearest point of fire department apparatus accessibility or at a location approved by the authority having 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 that hose 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 as follows:

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

(2)

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






5.9.5.4 Where the system demand pressure exceeds 150 psi (10.3 bar), the sign required by 5.9.5.3 a sign located at the fire department connection shall indicate the required 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 the building, a sign shall be attached to indicate the portion(s) of the building supplied.

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.

10.4.5 Pipe under railroad tracks shall be buried at a minimum depth of 4 ft (1.2

requirements .





It is not unusual for a user/operator of a railroad track to require a minimum of 10 ft from top of rail to top of pipe passing under their rail. This could be a very costly error for the installer if they failed to contact the owner/operator of the railroad track.




13.2 Mains Not Supplying Hydrants. For mains that do not supply hydrants, sizes smaller than 6 in. (152 mm) shall be permitted to be used, subject to the following restrictions:

(1) The main shall supply only the following types of systems:

(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 total demand at the appropriate pressure.

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

(1) For private fire service mains with direct connections from public waterworks mains only or with fire pumps installed in the connections from the street mains, no tanks or reservoirs, no physical connection from other water supplies, no antifreeze or other additives of any kind, and with all drains discharging to atmosphere, dry well, or other safe outlets, an approved double check valve assembly is recommended.

(2) For private fire service mains with direct connections from the public water supply main plus one or more elevated storage tanks or fire pumps taking suction from aboveground covered reservoirs or tanks (all storage facilities are filled or connected to public water only, and the water in the tanks is to be maintained in a potable condition), an approved double check valve assembly is recommended.

(3) For private fire service mains directly supplied from public mains with an auxiliary water supply, such as a pond or river on or available to the premises and dedicated to fire department use; or for systems supplied from public mains and interconnected with auxiliary supplies, such as pumps taking suction from reservoirs exposed to contamination or rivers and ponds; driven wells, mills, or other industrial water systems; or for systems or portions of systems where antifreeze or other solutions are used, an approved reduced- pressure zone-type backflow preventer is recommended.

(4) For private fire service mains with fire department connections located within 1750 ft (533.4 m) of a non potable water source, an approved reduced- pressure zone-type backflow preventer is recommended.


This is an AWWA requirement that is being increasingly enforced. Since this standard includes

annex language on backflow prevention, this should be added.

As there is normally no circulation of water in private fire mains, they require greater depth of covering than do public mains. Greater depth is required in a loose gravelly soil (or in rock) than in compact soil containing large quantities of clay.

A.10.8.3

A method for providing thrust restraint is the use of restrained joints. A restrained joint 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 balances the thrust forces.

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

The following documents apply to the design, calculation, and determination of restrained joint systems:

The pressure that exists at a given point under normal distribution system conditions 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 Universal Transverse Mercator (UTM) numerical grid. Every modest size home in a discrete area (city) can be described using 8-digits (e.g., 1234 5678). By adding a two-letter prefix (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, an 8-digit coordinate would uniquely identify the location and it could be used to calculate approximate distances, when necessary.

Annex A Explanatory Material Annex A is not a part of the recommendations of this NFPA document but is included 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 NFPA documents in a broad manner, since jurisdictions and approval agencies vary, as do their responsibilities. Where public safety is primary, the authority having jurisdiction may be a federal, state, local, or other regional department or individual such as a fire chief; fire marshal; chief of a fire prevention bureau, labor department, or health department; building official; electrical inspector; or others having statutory authority. For insurance purposes, an insurance inspection department, rating bureau, or other insurance company representative may be the authority having jurisdiction. In many circumstances, the property owner or his or her designated agent assumes the role of the authority having jurisdiction; at government installations, the commanding officer or departmental official may be the authority having jurisdiction. A.3.2.2 Listed. The means for identifying listed equipment may vary for each organization concerned with product evaluation; some organizations do not recognize equipment as listed unless it is also labeled. The authority having jurisdiction should utilize the system employed by the listing organization to identify a listed product. A.4. 11.2 Consider US National Grid coordinates for Location of hydrants, in addition

to any other standard description. A coordinate to a precision of eight

digits equates to an area of 10 meters square (33' x 33'). In practically all

cases, this will uniquely define the hydrant. Two oordinates can also be

used for distance calculations between hydrants. Example: 17R NM 3877 4016

A.4. 13.1 When flow test data are needed, such data should not be more than 5 years old since conditions in the piping and system demands can change. It is not the intent of 4.13.1 to require routine 5-year testing of each hydrant if there is no immediate need for flow test data or if test data less than 5 years old are available from an adjacent 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
