____________________________________________________________ 20-1 Log #CC3 Final Action: Accept (Entire Document) ____________________________________________________________ Submitter: Technical Committee on Fire Pumps Comment on Proposal No: 20-183 Recommendation: Modify the following sections: 3.3 General Definitions. 3.3.2 (NEW) Fire Pump Alarm. A supervisory signal indicating an abnormal condition requiring immediate attention. 3.3.35* Signal. An indicator of status. A.3.3.35 A response to signals is expected within two hours. 5.14.9* Devices in Suction Piping. (3) Suitable devices shall be permitted to be installed in the suction supply piping or stored water supply and arranged to activate a n alarm signal if the pump suction pressure or water level falls below a predetermined minimum. 5.23* Alarms. Other Signals. When required by other sections of this standard, alarms signals shall call attention to improper conditions in the fire pump equipment. A.5.23 In addition to those conditions that require alarm signals for pump controllers and engines, there are other conditions for which such alarms signals might be recommended, depending upon local conditions. Some of these supervisory alarm conditions are as follows: (1) Low pump room temperature (2) Relief valve discharge (3) Flowmeter left on, bypassing the pump (4) Water level in suction supply below normal (5) Water level in suction supply near depletion (6) Diesel fuel supply below normal (reference Proposal 20-167) (7) Steam pressure below normal Such additional alarms signals can be incorporated into the trouble alarms signals already provided on the controller, or they can be independent. 10.1.1.2 Accessory devices, including Fire Pump alarm monitoring and signaling means, are included where necessary to ensure the minimum performance of the aforementioned equipment. 10.4.5.6.2* Single Phase. A.10.4.5.6.2 The alarms signal should incorporate local visible indication and contacts for remote indication. The alarms signal can be incorporated as part of the power available indication and loss of phase signal [see 10.4.6.1 and 10.4.7.2(B)]. 10.4.5.6.2.1 Sensors shall be permitted to prevent a three-phase motor from starting under single-phase condition. 10.4.5.6.2.2 Such sensors shall not cause disconnection of the motor if it is running at the time of single-phase occurrence. 10.4.5.6.2.3 Such sensors shall be monitored to provide a local visible alarms signal in the event of malfunction of the sensors. 10.4.6* Alarm and Signal Devices on Controller. A.10.4.6 The pilot lamp for alarm and signal service should have operating voltage less than the rated voltage of the lamp to ensure long operating life. When necessary, a suitable resistor or potential transformer should be used to reduce the voltage for operating the lamp. 10.4.7* Fire Pump Alarm and Signal Devices Remote from Controller. A.10.4.7 Where unusual conditions exist whereby pump operation is not certain, a “failed-to-operate” Fire Pump alarm is recommended. In order to supervise the power source for the Fire Pump alarm circuit, the controller can be arranged to start upon failure of the supervised alarm circuit power. 10.4.7.1 Where the pump room is not constantly attended, audible or visible alarms signals powered by a source not exceeding 125 V shall be provided at a point of constant attendance. 10.4.7.2 These Fire Pump alarms and signals shall indicate the information in 10.4.7.2(A) through 10.4.7.2(D). (A) Pump or Motor Running. The alarm signal shall actuate whenever the controller has operated into a motor-running condition. This alarm signal circuit shall be energized by a separate reliable supervised power source or from the pump motor power, reduced to not more than 125 V. (B) Loss of Phase. (1) The Fire Pump alarm shall actuate whenever The loss of any phase at the line terminals of the motor contactor shall be monitored is lost. (2) All phases shall be monitored.

A.14.2.13 To verify the operation of the alternate ECM, with the motor stopped, move the ECM selector switch to the alternate ECM position. Repositioning of this should cause an alarm a signal on the fire pump controller. Start the engine; it should operate normally with all functions. Shut engine down, switch back to the primary ECM, and restart the engine briefly to verify that correct switchback has been accomplished.    To verify the operation of the redundant sensor, with the engine running, disconnect the wires from the primary sensor. There should be no change in the engine operation. Reconnect the wires to the sensor. Next, disconnect the wires from the redundant sensor. There should be no change in the engine operation. Reconnect the wires to the sensor. Repeat this process for all primary and redundant sensors on the engines. Note: If desired, the disconnecting and reconnecting of wires to the sensors can be done while the engine is not running, then starting the engine after each disconnection and reconnection of the wires to verify engine operation. 14.3.2 The manual shall contain the following: (1) A detailed explanation of the operation of the component (2) Instructions for routine maintenance (3) Detailed instructions concerning repairs (4) Parts list and parts identification

(5) Schematic electrical drawings of controller, transfer switch, and Fire Pump control alarm panels Substantiation: There was no agreement with regards to the terms alarm and signal. This comment addresses the intent of numerous comments that were made relating to these terms. Committee Meeting Action: Accept Number Eligible to Vote: 27 Ballot Results: Affirmative: 25 Negative: 1 Ballot Not Returned: 1 Mezsick, S. Explanation of Negative:    HAAGENSEN, D.: The term ‘alarm signal’ is traditionally reserved for a signal that is generated as a result of a fire, and requires that the fire department respond in emergency mode. The term ‘fire pump alarm’ is confusing and such signals will erroneously be connected to fire alarm panels as an ‘alarm signal’. No one participating in the Task Group thought that any fire pump controller signal should be treated as a fire alarm signal. I am worried that firefighters responding to or returning from a ‘fire pump alarm’ signal could suffer needless casualties. Comment on Affirmative:    CASTLES, H.: I had a problem with the substantiation statement specifically “no agreement” part. My comment is to revise the substantiation statement for Comment 20-1 as follows:    Although there was discussion regarding the use of the term “signal”, agreement was achieved. There were various conflicting positions on the use of the term “alarm” making consensus difficult. This comment addresses the intent of numerous comments that were made relating to these terms.    WENZEL, L.: I understand that the task group did a great deal of work gyrating the intent of the proposal and the resulting comment. I agree that this proposal/comment is a step in the right direction, but feel that more work needs to be done.    As a member of the Technical Correlating Committee on Signaling Systems for the Protection of Life and Property (NFPA 72), I intend to bring the definition of “Alarm” to that committee, for clarification within that document, as a foundation for standardization of the term.    It will still be confusing to the user of both documents, and I feel that we have moved some of the way to correct the situation, but there has to be better consistency, in my opinion. ____________________________________________________________ 20-2 Log #11 Final Action: Accept in Principle in Part (2.3.5) ____________________________________________________________ Submitter: John D. Jensen, Fire Protection Consultant Comment on Proposal No: 20-2 Recommendation: Reconsider inclusion of this design reference in the standard by Creating a new Annex D that includes the complete text of the document. A reference should be included in Chapter 9 to Annex A as 9.1.3* and then to the new Annex D which would be the NEMA Publication ICS14-2001` Substantiation: This document is an important design document in sizing and arranging of the electrical system that feeds the fire pump installation and should be included to provide design guidance for the engineers designing the electrical system required by electric motor driven fire pumps Committee Meeting Action: Accept in Principle in Part Propose a new Section 10.1.3 to read as follows: 10.1.3 Design. 10.1.3.1* All electrical control equipment design shall comply with NFPA 70, National Electrical Code, Article 695, and other applicable documents. A.10.1.3.1 All electrical control equipment design should also follow the guidelines within NEMA Publication ICS14 – 2001. Committee Statement: Meets the intent of the submitter. Number Eligible to Vote: 27 Ballot Results: Affirmative: 25 Negative: 1 Ballot Not Returned: 1 Mezsick, S. Explanation of Negative:    KHEIR, H.: I think the intent of the submitter is to include the NEMA publication ICS14-2001 as new Annex D, which I think will be valuable information, especially for international user.    Also I think we need to change “ICS 14-2001” to ICS 14-2004”, as 2004 is the one existing now. ____________________________________________________________ 20-3 Log #8 Final Action: Reject (Chapter 3 Definitions (GOT)) ____________________________________________________________ Submitter: Thomas P.

____________________________________________________________ 20-11 Log #40 Final Action: Accept in Principle (5.15.10) ____________________________________________________________ Submitter: Kenneth E. Isman, National Fire Sprinkler Association Comment on Proposal No: 20-39 Recommendation: Accept proposal 20-39. Substantiation: No justification has even been given by the committee that substantiates any prohibition against pressure reducing valves. Other fire protection committees are convinced of the reliability and safety of these valves. For the committee to know that they are being used in other positions and then prohibit them in the discharge piping does not make sense. If they are going to be installed, the best location is in the discharge piping so that they will be exercised each time the pump is flow-tested and so that the pump test header can be used to also test the pressure reducing valve. If the valve is installed downstream of the discharge piping, it will need some additional test header to be tested and maintained correctly. This just adds needless cost to the system. During committee discussion, the concern seemed to be over single pressure reducing valves. Our proposal would not have allowed a single pressure reducing valve. It would only have allowed two pressure reducing valves in parallel, which would have increased reliability over the single valve installation.    A Task Group of several NFPA committees met recently to discuss the use of pressure reducing valves throughout the NFPA standards. The conclusion of this task group was that pressure reducing valves are reliable and can be used safely on fire protection systems. After this Task Group meeting, the NFPA Standpipe committee met and discussed the use of master pressure reducing valves on standpipe systems to control large zones. This committee concluded that mast pressure reducing devices could be used, but wanted to take care of the situation where failure of the device in an open position might occur. They required two devices to be installed in series to prevent this from becoming a problem. The NFPA 20 committee could do something similar.    To continue to prohibit the use of a listed and reliable device without any technical substantiation is a restraint of trade and may become a significant legal problem for the NFPA. Committee Meeting Action: Accept in Principle Add new text to read: A.5.7.4.2 It is not the intent to restrict the use of pressure reducing valves down stream of the discharge isolation valve for the purpose of meeting the requirements of Section 5.7.4. Committee Statement: The reliability of these pressure reducing valves in fire protection application has not been established and design options are available to avoid the use of these valves. If installed as a “master” pressure reducing valve downstream of the fire pump, the valve represents a single point of failure that could impair the entire system. Committee members have experienced several failures of pilot operated valves. While the current experience can not be analyzed statistically, it does point out the need to establish the reliability of the valves before encouraging their use.    It may be theoretically possible to improve reliability by using multiple pressure reducing valves, however, the valves may fail either open or closed. Valves in parallel are required to reduce the possibility of depriving the fire protection system of water in case a valve failed shut. However installing valves in parallel increases the possibility of over pressurizing the system from a valve failing open. Valves in series are required to reduce the possibility of over pressurizing the system if a valve failed open. However installing valves in series increases the possibility of depriving the fire protection system of water in case a valve failed shut. In addition failure of multiple valves cannot be statistically treated as independent events, because the valves are in a similar environment and the most likely causes of failure are environmentally related.    Pressure reducing valves also have a limited operating flow range, which results in the need to install smaller valve(s) in parallel with the main pressure reducing valve. Low flow rates in larger valves may result in wide swings in discharge pressure.    A manual bypass could be installed to allow bypassing the pressure reducing valve in the event the valve failed closed, however, this is likely to result in over-pressurization. Emergency manual operation of a normally closed bypass in the event the pressure reducing valve failed closed during a fire may be acceptable if it results in a nominal overpressurization, however, a catastrophic failure is likely if it results in a severe over-pressurization. A severe over-pressurization is likely if the situation involves pressure reducing valves for multiple vertical zones supplied from a single pump. If used in a vertical zone application, overpressurization and failure in a low zone could deprive a higher zone of water.    Unlike pressure reducing valves used on individual hose valves or floors whose failure still allows use of hose valves from other floors, the failure of a “master” pressure reducing valve impairs the entire system. Number Eligible to Vote: 27 Ballot Results: Affirmative: 24 Negative: 2 Ballot Not Returned: 1 Mezsick, S.

Explanation of Negative:    KHEIR, H.: I need to ask again the committee members to reconsider moving from APR to Reject, the technical committee of NFPA 20 spent years, and years rejecting to include this type of valves in the code. This statement was clear.    Actually till 1996 edition, NFPA included in the formal interpretation attachment F.I. 83-6A, the technical committee was clear not to accept the pressure regulating valve, also it was clear that the committee against including this in the code section, and rejected 20-10, Log #1.    In Log #40, the Substantiation was clear about the problem we feel about this kind of valves, I clearly indicated actual field problems, which many came with more information, and agreement about the operation of the fire pumps, with direct effect on jockey pump, with change of failure during fire case, we not even indicated how to solve the problems will result of this type of valve.    To say the Annex is not code, so there is no responsibility for use, but we need to consider that it is still explanatory material from the committee, and in international market it can be bad use, we not speaking here about the legalities, but about risk life, even NFPA 24, still not in full acceptance of pressure regulating valve (please refer to 5.3.1, No pressureregulating valve shall be used in the water supply, except by special permission of the authority having jurisdiction.)    In our discussion I indicated distance which I tested in the field many times to reduce the effect of such valve on the operation of fire pumps, this was rejected, without indication or field tests which show the safe distance.    I hope the submitter will provide field reports indicating the right distance for fitting the pressure regulating valve, before we even consider putting this statement as Annex material.    Members of the technical committee need to understand that international users, consultants, and authorities look for NFPA document with respect, both as a code, and Annex materials.    ROY, M.: Recommend that the Committee Reject the Comment.    Substantiation: The Fire Pump Technical Committee’s position on the reliability of pressure reducing valves is based on prior experience in application of these valves in “standby” or “intermittent” service. My experience with these valves is that their reliability is subject to many sitespecific conditions such as water quality, maintenance procedures, valve design, and proper application (arrangement and setting). Further evidence in fire protection applications of “master” pressure reducing valves suggests that these valves do fail with some frequency when applied in standpipe systems. The results of such application have been multimillion dollar property losses and the loss of life. The One Meridian Plaza fire in Philadelphia and First Interstate Bank Tower fire in Los Angeles are two such cases. These failures are documented in both NFPA and FEMA reports which should be reviewed by the submitter.    As a final note on evidence and experience, the submitter of the original proposal provided no experimental evidence of reliability of these valves in this application. In order to make important changes to fire protection codes and standards, the burden of evidence is on the submitter, not on the committee reviewing the proposals to provide otherwise.    Regarding the restraint of trade comment, all committee members must consider commercial issues and fair business practices in regulating or restricting the use of products. The restriction or prohibition of pressure reducing valves on standpipe systems is one such example where the committee must decide what the trade offs are between the cost of a fire protection system and the resulting property damage and loss of life. Fire protection is a business, but it is most importantly a duty and obligation to the public. I cannot in good conscience support compromising public safety and the safety of those in the fire services by supporting the committee action to recognize the application of master pressure reducing valves. Comment on Affirmative:    HAAGENSEN, D.: It is interesting to note that the Committee voted to Accept in Principal. This would mean that the recommendation of Proposal 20-39 has been accepted, in addition to the Committee adding the language that appears in the Committee Action of this Comment. If only the text that appears in the Committee Action of this Comment is added, and not that in the recommendation of Proposal 20-39, the Committee would have Rejected this Comment to signal that it entirely disagrees with the intent of the submitter.    ISMAN, K.: With respect to Comment 20-11, we agree with the committee’s action, but are concerned with the committee statement, which at times is in conflict with the committee action. Ultimately, we believe that if the committee is going to allow pressure reducing devices in the supply pipe to a fire protection system, they should also allow them in the discharge piping of the pump so that they can be tested. The Fire Pump Committee is allowing a device to be installed in a position where it is least likely to be tested and prohibiting the device from being installed in the position where it is most likely to be tested. Since the performance is the same except for the testing implications, we think the committee is actually decreasing the reliability of the pump installation.

Number Eligible to Vote: 27 Ballot Results: Affirmative: 25 Negative: 1 Ballot Not Returned: 1 Mezsick, S. Explanation of Negative:    HAAGENSEN, D.: This establishes a double standard within NFPA 20, whereby the fire protection system designer can design for suctions supplying less than the 150 percent rated capacity of the fire pump through the use of an inherently less reliable break tank arrangement. The standard does not currently permit the design of the fire pump suction to consider less than 150 percent pump rated capacity. ____________________________________________________________ 20-14 Log #14 Final Action: Reject (6.3.4, 6.3.4.3) ____________________________________________________________ Submitter: Frank L. Moore, Moore Pump and Equipment, Inc. Comment on Proposal No: 20-50 Recommendation: Reinsert entire section as printed in 2003 NFPA 20. Substantiation: Serviceability was a major issue on allowing inline pumps into the 1996 NFPA 20. Inline strainers was the option the committee elected to use. This proposal does not address the lifting required for large inline pumps. Committee Meeting Action: Reject Committee Statement: Current experience indicates that accessing the impeller on in-line pumps is less difficult than horizontal split case pumps and can be done without disconnecting the electrical connection. Under these circumstances the concern for preventing small objects from entering the impeller is overridden by the concern over the strainer restricting the water supply to the fire pump. Number Eligible to Vote: 27 Ballot Results: Affirmative: 25 Negative: 1 Ballot Not Returned: 1 Mezsick, S. Explanation of Negative:    DORINI, A.: I agree that service is a problem on large in-line fire pumps. The committee agreed when this was added to the document. Alternate methods given in committee action are fine but I do not think the primary method of serviceability for these type pumps, the strainer should be taken out. Removing the text from the document no longer allows the use of the strainer. It is important and should remain in the document. ____________________________________________________________ 20-15 Log #2 Final Action: Reject (8.4.5) ____________________________________________________________ Submitter: James Copeland, Federal Express Corp.

The overflow line shall be continuous piping, without valves or traps, to the source tank or collection system. The capacity of the overflow line shall exceed the delivery capacity of the supply lines to the fuel tank. Substantiation: The NFPA 20 (1998) code does not incorporate NPFA 37 5-5.2.

Nasby, Master Control Systems, Inc. Comment on Proposal No: 20-69 Recommendation: Consider adding submitter’s (Dana Haagensen) power quality material from proposed clauses 9.3.1 thru 9.4 as main body or to Appendix (Annex A). Reword (should –vs- shall) and renumber clauses as needed. A re-write as appendix material as follows:    A.9.3.2 Other Sources. Except for an arrangement described in 9.3.3 or 9.3.4, at least one back-up source of power may be required when one or more of the following conditions of the normal source of power exists:    (1) The source power plant has experienced any shut downs of longer than 4 continuous hours in the year prior to plan submittal. Note that NFPA 25 begins to require special undertakings (i.e. fire watches) when a water-based fire protection system is taken out of service for longer than 4 hours. If the normal source power plant has been intentionally shut down for longer than 4 hours in the past, it is reasonable to require a back-up source of power.    (2) Power outages have been experienced in the area of the protected facility caused by failures in the power grid that were not due to natural disasters or electric grid management failure. Note that this standard does not require that the normal source of power is infallible. NFPA 20 does not intend to require a back-up source of power for every installation using an electric motor driven fire pump. Should the normal source of power fail due to a natural disaster (hurricane) or due to a problem with electric grid management (regional blackout), the fire protection system could be supplied through the fire department connection. However, if the power grid is known to have had problems in the past (i.e. switch failures or animals shorting a substation), it is reasonable to require a back-up source of power.    (3) The normal source of power is supplied on-site by overhead conductors outside the protected facility. More and more often, fire departments responding to an incident at the protected facility will not operate aerial apparatus near live overhead power lines, without exception. A back-up source of power is required in case this scenario occurs and the normal source of power must be shut off. Additionally, many utility providers will remove power to the protected facility by physically cutting the overhead conductors. If the normal source of power is provided by overhead conductors, which will not be identified, the utility provider could mistakenly cut the overhead conductor supplying the fire pump.    (4) Disconnect switches or overcurrent protection devices are installed in the normal source of power that do not comply with 9.2. Power disconnection and activated overcurrent protection should only occur in the fire pump controller. The provisions of 9.2.3 for the disconnect switch and overcurrent protection essentially require disconnection and overcurrent protection to occur in the fire pump controller. If unanticipated disconnect switches or overcurrent protection devices are installed in the normal source of power that do not meet the requirements of 9.2.2, the normal source of power must be considered not reliable and a back-up source of power is necessary.    (5) Other conditions that would make the normal source of power be considered not reliable.    A.9.3.2.1(A) A back-up source of power may not be required where a back-up engine driven or back-up steam turbine driven fire pump is installed in accordance with NFPA 20.    A.9.3.2.1(B) A back-up source of power may not be required when acceptable to the authority having jurisdiction. Note that this standard recognizes that prescriptive standards cannot address every possible situation. Thus, the authority having jurisdiction may accept a normal source of power as reliable based on a project specific situation even though the normal source of power does not comply the regular requirements of Section 9.2.    A.9.3.2.2 When provided, the back-up source of power shall not be supplied through overhead conductors outside the protected facility.    A.9.3.2.3 For fire pump installations using the power supply arrangement of 9.2.2.4 (Old 9.2.5.3 - Campus Style Feeder Sources), and having more than one disconnecting means supplied by a single feeder, the overcurrent protection device(s) in each disconnecting means shall be selectively coordinated with any other supply side overcurrent protective device(s) to avoid unnecessary loss of power to other emergency loads. Substantiation: Field personnel frequently look for additional guidance regarding suitable fire pump power supplies.

____________________________________________________________ 20-33 Log #10 Final Action: Reject (11.6.4) ____________________________________________________________ Submitter: John D. Jensen, Fire Protection Consultant Comment on Proposal No: 20-135 Recommendation: Change the “2/3” fuel tank level requirement to “The level required for twice the duration of the maximum required water flow for the engine supplied operating at 150 percent of rated capacity”. Substantiation: Many diesel fuel tanks are being oversized to accommodate storage of fuel for longer than one year. The fuel requires changing and/or additives to prevent clogging up the engine and so it is important to know how much fuel is required as a minimum and how much fuel is being stored for future use. Often, the fuel tank and the engine installed are not coordinated, this results in too little fuel or too much fuel. Committee Meeting Action: Reject Committee Statement: The current language provides clear guidance and adequate fuel supply. The submitter’s comments are unclear as to how tank size should be determined. Number Eligible to Vote: 27 Ballot Results: Affirmative: 26 Ballot Not Returned: 1 Mezsick, S. ____________________________________________________________ 20-34 Log #13 Final Action: Reject (11.6.4) ____________________________________________________________ Submitter: Shane M. Clary, Bay Alarm Company Comment on Proposal No: 20-135 Recommendation: Accept in Principal Proposal 20-135.    A fuel level switch shall be provided to activate at the 2/3 tank level. A supervisory signal circuit in accordance with the requirements of NFPA 72 shall be provided to the building fire alarm system, where present.    The revised text is “in accordance with the requirements of NFPA 72 shall be provided to the building fire alarm system, where present.” Substantiation: The Technical Committee did not fully provide a reason why the signal should not be supervised by the building fire alarm system. The revised text makes it clear that one does not need to install a fire alarm system to provide this supervision, but if a system is within the protected premises, then this signal shall be supervised.    While this signal should be annunciated at the pump controller, being also supervised by the building’s fire alarm system will assure that the pump fuel level is addressed in a timely manner. Committee Meeting Action: Reject Committee Statement: This is a minimum standard with the intent to provide local fuel level indication. Additional switches for remote annunciation are allowed. See Committee Action on 20-35 (Log #6). Number Eligible to Vote: 27 Ballot Results: Affirmative: 26 Ballot Not Returned: 1 Mezsick, S. ____________________________________________________________ 20-35 Log #6 Final Action: Accept in Principle (11.6.4.1) ____________________________________________________________ Submitter: Gayle Pennel, Schirmer Engineering Corporation Comment on Proposal No: 20-135 Recommendation: Change the word “possible” to “practical” in 11.6.4.1 as follows:    11.6.4.1 The fuel storage tanks shall be kept as full as practical possible at all times, but never less than 66 percent (2/3) of tank capacity. A fuel level switch shall be provided to activate at the 2/3 tank level. Substantiation: The words “tanks shall be kept as full as possible at all times” is impractical, and may be unenforceable. It is “possible” to keep the tanks full at all times by filling the tanks even while the engine is running. Committee Meeting Action: Accept in Principle    Revise language as follows:    In addition to the submitter recommendations, change “switch” to “indicator”.

The refill... minimum of 5 times at suction pressure no higher than guaranteed by the water supplier. Substantiation: This test should be repeated annually to insure changes in supply pressure has not rendered the system inoperable. This system must be confirmed to be operable at minimum supply pressure to the pump. Committee Meeting Action: Reject Committee Statement: Periodic inspections are defined in NFPA 25. Number Eligible to Vote: 27 Ballot Results: Affirmative: 26 Ballot Not Returned: 1 Mezsick, S. ____________________________________________________________ 20-38 Log #7 Final Action: Accept (Table 14.5) ____________________________________________________________ Submitter: Bill M. Harvey, Harvey & Associates, Inc. Comment on Proposal No: 20-159 Recommendation: Insert revised Table 14.5 “Summary of Components Replacement Testing Requirements”. Revised Table 14.5 is shown on the following page.    All other text and substantiations to remain as proposed. Substantiation: The revised Table 14.5 further defines the requirements for component replacement testing requirements. A revised version of this table should be submitted by the Committee to the NFPA 25 committee to align the proposed Table 8.6.1. Committee Meeting Action: Accept    Revise table further as shown following the recommendation table. Number Eligible to Vote: 27 Ballot Results: Affirmative: 25 Negative: 1 Ballot Not Returned: 1 Mezsick, S. Explanation of Negative:    ISMAN, K.: With respect to Comment 20-38, we are concerned that the committee did not give enough thought to the items that require a full acceptance test of the pump. An old pump may have some wear and not perform as well as it did when it was originally installed, but still may be fine for the fire protection system. If an item is replaced, the whole pump should not be required to meet the original acceptance criteria, which mandates the replication of the manufacturer’s shop curve exactly (within the accuracy of the equipment used for the test). Some drop-off in performance should still be allowed similar to the 5 percent allowed by NFPA 25 for existing pumps. ____________________________________________________________ 20-39 Log #32 Final Action: Reject (A.5.7.1) ____________________________________________________________ Submitter: Dana R. Haagensen, Massachusetts Office of the Fire Marshal Comment on Proposal No: 20-161 Recommendation: Delete the words “and private” in the first sentence of A.5.7.1, and delete “as is typical in municipal water systems” in the last sentence of A.5.7.1 Substantiation: 1. This section is intended to explain that the requirements of the standard do not contemplate a pump used in municipal waterworks systems. Such pumps are covered by other standards.    2. The committee cannot state in the annex that the standard does not apply to private fire protection pumps when that is explicitly the scope of the document according to section 1.1.    3. If a private development (campus) needs a fire protection pump, this is typically accomplished by installing a dedicated fire pump (in accordance with NFPA 20) in parallel with a domestic pump or as a branch/loop off of the water supply. The statement in exisitng A.5.7.1 would allow any developer to bypass NFPA 20 requirements by installing combined domestic/fire main(s).    I can see developers putting garden hose connections on “fire mains” for a building, citing existing A.5.7.1, as justification for installing “any old” pump. See my companion comment on this section. Committee Meeting Action: Reject Committee Statement: Introduces a topic that was not previously considered. Number Eligible to Vote: 27 Ballot Results: Affirmative: 25 Negative: 1 Ballot Not Returned: 1 Mezsick, S. Explanation of Negative:    HAAGENSEN, D.: The topic of dual purpose pumps was raised in Proposal 20-161, so the Comment should not have been considered new material. The Committee should have properly resolved the conflict within NFPA 20 between the requirements in Section 1.1 and the information in Annex Section A.5.7.1.

I

The Technical Report Session of the NFPA Annual Meeting The process of public input and review does not end with the publication of the ROP and ROC. Following the completion of the Proposal and Comment periods, there is yet a further opportunity for debate and discussion through the Technical Report Sessions that take place at the NFPA Annual Meeting. The Technical Report Session provides an opportunity for the final Technical Committee Report (i.e., the ROP and ROC) on each proposed new or revised code or standard to be presented to the NFPA membership for the debate and consideration of motions to amend the Report. The specific rules for the types of motions that can be made and who can make them are set forth in NFPA’s rules which should always be consulted by those wishing to bring an issue before the membership at a Technical Report Session. The following presents some of the main features of how a Report is handled. What Amending Motions are Allowed. The Technical Committee Reports contain many Proposals and Comments that the Technical Committee has rejected or revised in whole or in part. Actions of the Technical Committee published in the ROP may also eventually be rejected or revised by the Technical Committee during the development of its ROC. The motions allowed by NFPA rules provide the opportunity to propose amendments to the text of a proposed code or standard based on these published Proposals, Comments and Committee actions. Thus, the list of allowable motions include motions to accept Proposals and Comments in whole or in part as submitted or as modified by a Technical Committee action. Motions are also available to reject an accepted Comment in whole or part. In addition, Motions can be made to return an entire Technical Committee Report or a portion of the Report to the Technical Committee for further study. The NFPA Annual Meeting, also known as the World SafetyConference and Exposition®, takes place in June of each year. A second Fall membership meeting was discontinued in 2004, so the NFPA Technical Report Session now runs once each yearat the Annual Meeting in June. Who Can Make Amending Motions. Those authorized to make these motions is also regulated by NFPA rules. In many cases, the maker of the motion is limited by NFPA rules to the original submitter of the Proposal or Comment or his or her duly authorized representative. In other cases, such as a Motion to Reject an accepted Comment, or to Return a Technical Committee Report or a portion of a Technical Committee Report for Further Study, anyone can make these motions. For a complete explanation, NFPA rules should be consulted. The filing of a Notice of Intent to Make a Motion. Before making an allowable motion at a Technical Report Session, the intended maker of the motion must file, in advance of the session, and within the published deadline, a Notice of Intent to Make a Motion. A Motions Committee appointed by the Standards Council then reviews all notices and certifies all amending motions that are proper. The Motions Committee can also, in consultation with the makers of the motions, clarify the intent of the motions and, in certain circumstances, combine motions that are dependent on each other together so that they can be made in one single motion. A Motions Committee report is then made available in advance of the meeting listing all certified motions. Only these Certified Amending Motions, together with certain allowable Follow-Up Motions (that is, motions that have become necessary as a result of previous successful amending motions) will be allowed at the Technical Report Session. Consent Documents. Often there are codes and standards up for consideration by the membership that will be non-controversial and no proper Notices of Intent to Make a Motion will be filed. These “Consent Documents” will bypass the Technical Report Session and head straight to the Standards Council for issuance. The remaining Documents are then forwarded to the Technical Report Session for consideration of the NFPA membership. Important Note: The filing of a Notice of Intent to Make a Motion is a new requirement that takes effect beginning with those Documents scheduled for the Fall 2005 revision cycle that reports to the June 2006 Annual Meeting Technical Report Session. The filing of a Notice of Intent to Make a Motion will not, therefore, be required in order to make a motion at the June 2005 Annual Meeting Technical Report Session. For updates on the transition to the new Notice requirement and related new rules effective for the Fall 2005 revision cycle and the June 2006 Annual Meeting, check the NFPA website.

Action on Motions at the Technical Report Session. In order to actually make a Certified Amending Motion at the Technical Report Session, the maker of the motion must sign in at least an hour before the session begins. In this way a final list of motions can be set in advance of the session. At the session, each proposed Document up for consideration is presented by a motion to adopt the Technical Committee Report on the Document. Following each such motion, the presiding officer in charge of the session opens the floor to motions on the Document from the final list of Certified Amending Motions followed by any permissible Follow-Up Motions. Debate and voting on each motion proceeds in accordance with NFPA rules. NFPA membership is not required in order to make or speak to a motion, but voting is limited to NFPA members who have joined at least 180 days prior to the session and have registered for the meeting. At the close of debate on each motion, voting takes place, and the motion requires a majority vote to carry. In order to amend a Technical Committee Report, successful amending motions must be confirmed by the responsible Technical Committee, which conducts a written ballot on all successful amending motions following the meeting and prior to the Document being forwarded to the Standards Council for issuance. Standards Council Issuance One of the primary responsibilities of the NFPA Standards Council, as the overseer of the NFPA codes and standards development process, is to act as the official issuer of all NFPA codes and standards. When it convenes to issue NFPA documents it also hears any appeals related to the Document. Appeals are an important part of assuring that all NFPA rules have been followed and that due process and fairness have been upheld throughout the codes and standards development process. The Council considers appeals both in writing and through the conduct of hearings at which all interested parties can participate. It decides appeals based on the entire record of the process as well as all submissions on the appeal. After deciding all appeals related to a Document before it, the Council, if appropriate, proceeds to issue the Document as an official NFPA code or standard. Subject only to limited review by the NFPA Board of Directors, the Decision of the Standards Council is final, and the new NFPA code or standard becomes effective twenty days after Standards Council issuance. The illustration on page 9 provides an overview of the entire process, which takes approximately two full years to complete.
