NFPA 24 — May 2002 ROP — Copyright 2001, NFPA(Log #4)Committee: AUT-PRINFPA 2424- 4 - (4-1.1): RejectSUBMITTER: James W. Cragun, Phillips Petroleum Co.RECOMMENDATION: Revise text as follows:“4-1.1 .A valve shall be installed in the hydrant connection.”.Change “shall” to “should.”SUBSTANTIATION: Guard post can be used to protect the hydrantsin traffic areas.Self closing hydrants can be used.Sectional valves in mains between three or four hydrants.COMMITTEE ACTION: Reject.COMMITTEE STATEMENT: The Committee feels that the valve isnecessary for individual hydrant maintenance, not just for protectionof the device. Secondly, the NFPA Manual of Style prohibits the useof “should” in the body of the document.NUMBER OF COMMITTEE MEMBERS ELIGIBLE TO VOTE: 23VOTE ON COMMITTEE ACTION:AFFIRMATIVE: 20NOT RETURNED: 3 Lake, Mowrer, Trigg(Log #CP2)Committee: AUT-PRI24- 1 - (1-1 Scope): AcceptSUBMITTER: Technical Committee on Private Water Supply PipingSystemsRECOMMENDATION: Modify the scope to read as follows:1.1 Scope. This standard establishes the minimum requirementsfor installation of private fire service mains and their appurtenancessupplying automatic sprinkler systems, open sprinkler systems, waterspray fixed systems, foam systems, private hydrants, monitor nozzles,standpipe systems and hose houses. This standard also applies to“combined service mains” used to carry water both fire service andother use. The authority having jurisdiction shall always be consultedbefore installation or remodeling of private fire service mains.SUBSTANTIATION: The committee wanted to further clarify thescope of NFPA 24 and to remove redundant language.COMMITTEE ACTION: Accept.NUMBER OF COMMITTEE MEMBERS ELIGIBLE TO VOTE: 23VOTE ON COMMITTEE ACTION:AFFIRMATIVE: 20NOT RETURNED: 3 Lake, Mowrer, Trigg(Log #5)Committee: AUT-PRI24- 5 - (4-3.3and A-4.3.3 (New)): Accept in PrincipleSUBMITTER: Don Turno, Westinghouse Savannah RiverRECOMMENDATION: Revise text to read as follows:“The center of a hose outlet shall be not less than 18 in. (457 mm)[nor greater than 36 in. (914 mm)] above final grade, or whenlocated in a hose house, 12 in. (305 mm) above the floor.”Add new text to read as follows:A-4-3.3 In setting hydrants, due regard should be given to finalgrade line.(Log #7)Committee: AUT-PRI24- 2 - (3-3): Accept in PrincipleSUBMITTER: Tariq Bsharat, Nat’l Fire Sprinkler Assn.RECOMMENDATION: Delete Section 3-3.SUBSTANTIATION: Post Indicating Valves are not necessary onunderground lines to individual fire protection systems. The systemcontrol valve required by installation standards is sufficient forcontrolling the water supply.COMMITTEE ACTION: Accept in Principle.COMMITTEE STATEMENT: See the draft of NFPA 24 at the end ofthis report.NUMBER OF COMMITTEE MEMBERS ELIGIBLE TO VOTE: 23VOTE ON COMMITTEE ACTION:AFFIRMATIVE: 20NOT RETURNED: 3 Lake, Mowrer, Trigg(Log #2)Committee: AUT-PRI24- 3 - (3-6.2(c)): Accept in PartSUBMITTER: John F. Marthens, Alexander & Alexander, Inc.RECOMMENDATION: Change the existing sub-paragraph to read:(c) Valves locked in the open position.SUBSTANTIATION: Presently, the existing wording is not inagreement with a similar sub-section contained in NFPA 13, Section4-6.1.1.3(c). This disagreement may lead to confusion and conflictand should be eliminated.Additionally, wording in NFPA 24, Section 3-6.2(c) concerning thephrase “correct position” should be made to agree with NFPA 13.COMMITTEE ACTION: Accept in Part.Part 1: The correct position is not always the “open position”. Thispart is rejected.Part 2 is covered in NFPA 25.COMMITTEE STATEMENT: See the draft of NFPA 24 at the end ofthis report.NUMBER OF COMMITTEE MEMBERS ELIGIBLE TO VOTE: 23VOTE ON COMMITTEE ACTION:AFFIRMATIVE: 20NOT RETURNED: 3 Lake, Mowrer, TriggFigure A-4-3.3 Typical hydrant connection with minimum heightrequirements.Figure A-4-3.3 Typical hydrant connection with maximum heightrequirements.SUBSTANTIATION: When installing hydrants many contractors addspool pieces that when final grading is completed the hydrantsbecome to high for safe operation. When asked to lower the hydrantthe contractor states that they have met the code. There are no1092

Many times the contractor may addbackfill around the hydrant to meet the 18 in. requirement. However,all this does is create a mound around the hydrant. This is still notsafe to operate.COMMITTEE ACTION: Accept in Principle.COMMITTEE STATEMENT: See the draft of NFPA 24 at the end ofthis report.NUMBER OF COMMITTEE MEMBERS ELIGIBLE TO VOTE: 23VOTE ON COMMITTEE ACTION:AFFIRMATIVE: 20NOT RETURNED: 3 Lake, Mowrer, Trigg(Log #1)Committee: AUT-PRI24- 9 - (Chapter 9): RejectSUBMITTER: Gene Dorman, Publix Super Markets, Inc.RECOMMENDATION: Add minimum of one fire hydrant to firemain in order to remove foreign material that might have entered themain during the course of repair during a break in the main.SUBSTANTIATION: Without a hydrant on the main, when a breakoccurs to flush, foreign material will enter sprinkler system.COMMITTEE ACTION: Reject.COMMITTEE STATEMENT: This is outside the Scope of thisstandard. Flushing after repairs is (and should be) covered by NFPA25. Additionally, proposed wording is too restrictive; there are othermethods to flush private fire service mains (e.g., through the firedepartment connection).NUMBER OF COMMITTEE MEMBERS ELIGIBLE TO VOTE: 23VOTE ON COMMITTEE ACTION:AFFIRMATIVE: 20NOT RETURNED: 3 Lake, Mowrer, Trigg(Log #6)Committee: AUT-PRI24- 6 - (4-3.6): RejectSUBMITTER: Richard A. Pashkow, Sr., St. Petersburg Fire & RescueRECOMMENDATION: To be the same as NFPA 25, 4-2.2.4 for DryBarrel Hydrants. To be tested annually.Revise text to read as follows:4-3.6 To ensure proper functioning, all private hydrants are to betested at least annually, or by the requirements of the authorityhaving jurisdiction, and/or follow NFPA 25, Chapter 4 requirements.SUBSTANTIATION: NFPA 24, Chapter 4, 4-3.6 and NFPA 25,Chapter 4, 4-2.2.4 will be consistent with each other for Dry BarrelHydrants.COMMITTEE ACTION: Reject.COMMITTEE STATEMENT: This is outside the Scope of NFPA 24,and is covered in NFPA 25 where it belongs.NUMBER OF COMMITTEE MEMBERS ELIGIBLE TO VOTE: 23VOTE ON COMMITTEE ACTION:AFFIRMATIVE: 20NOT RETURNED: 3 Lake, Mowrer, Trigg(Log #9)Committee: AUT-PRI24- 10 - (9-2.2 Exception (New) ): Accept in PrincipleSUBMITTER: Tariq Bsharat, Nat’l Fire Sprinkler Assn.RECOMMENDATION: Add an Exception after 9-2.2 as follows:“Where required for safety measures, the pipe and joints shall bepermitted to be backfilled provided the sprinkler contractor takes theresponsibility for locating and correcting leakage in excess of thatpermitted in 9-2.3.2 and 9-2.3.2.”SUBSTANTIATION: Contractors must leave trenches exposed forlong periods of time while waiting to schedule tests with inspectionauthorities. They should be permitted to cover their work as long asthey take the responsibility for correcting problems. This concept isconsistent with the appendix.COMMITTEE ACTION: Accept in Principle.COMMITTEE STATEMENT: See the draft of NFPA 24 at the end ofthis report.NUMBER OF COMMITTEE MEMBERS ELIGIBLE TO VOTE: 23VOTE ON COMMITTEE ACTION:AFFIRMATIVE: 20NOT RETURNED: 3 Lake, Mowrer, Trigg(Log #3)Committee: AUT-PRI24- 7 - (7-1.1): Accept in PrincipleSUBMITTER: James W. Cragun, Phillips Petroleum Co.RECOMMENDATION: Delete the following:“7-1.1 .Steel Piping shall not be allowed for use in private fireservice main applications.”SUBSTANTIATION: Steel piping has been used successfully forservice mains in refineries and chemical plants for many years. Wheninstalled correctly and cathodically protected has provided manyyears of dependable service. This action puts steel piping in anunwarranted disadvantage which could result in legal action.COMMITTEE ACTION: Accept in Principle.COMMITTEE STATEMENT: See the draft of NFPA 24 at the end ofthis report.NUMBER OF COMMITTEE MEMBERS ELIGIBLE TO VOTE: 23VOTE ON COMMITTEE ACTION:AFFIRMATIVE: 20NOT RETURNED: 3 Lake, Mowrer, Trigg(Log #12)Committee: AUT-PRI24- 11 - (10-1.2): AcceptSUBMITTER: Richard W.
