A compilation of NFPA® TechnicalCommittee Reports on Proposals for public review and comment

Public Comment Deadline: August 31, 2012

Information on NFPA Codes and Standards Development

I. Applicable Regulations. The primary rules governing the processing of NFPA documents (codes, standards, recommended practices, and guides) are the NFPA Regulations Governing Committee Projects (Regs). Other applicable rules include NFPA Bylaws, NFPA Technical Meeting Convention Rules, NFPA Guide for the Conduct of Participants in the NFPA Standards Development Process, and the NFPA Regulations Governing Petitions to the Board of Directors from Decisions of the Standards Council. Most of these rules and regulations are contained in the NFPA Directory. For copies of the Directory, contact Codes and Standards Administration at NFPA Headquarters; all these documents are also available on the NFPA website at “www.nfpa.org.”

The following is general information on the NFPA process. All participants, however, should refer to the actual rules and regulations for a full understanding of this process and for the criteria that govern participation.

II. Technical Committee Report. The Technical Committee Report is defined as “the Report of the Technical Committee and Technical Correlating Committee (if any) on a document consisting of the ROP and ROC.” A Technical Committee Report consists of the Report on Proposals (ROP), as modified by the Report on Comments (ROC), published by the Association.

III. Step 1: Report on Proposals (ROP). The ROP is defined as “a report to the Association on the actions taken by Technical Committees and/or Technical Correlating Committees, accompanied by a ballot statement and one or more proposals on text for a new document or to amend an existing document.” Any objection to an action in the ROP must be raised through the filing of an appropriate Comment for consideration in the ROC or the objection will be considered resolved.

IV. Step 2: Report on Comments (ROC). The ROC is defined as “a report to the Association on the actions taken by Technical Committees and/or Technical Correlating Committees accompanied by a ballot statement and one or more comments resulting from public review of the Report on Proposals (ROP).” The ROP and the ROC together constitute the Technical Committee Report. Any outstanding objection following the ROC must be raised through an appropriate Amending Motion at the Association Technical Meeting or the objection will be considered resolved.

V. Step 3a: Action at Association Technical Meeting. Following the publication of the ROC, there is a period during which those wishing to make proper Amending Motions on the Technical Committee Reports must signal their intention by submitting a Notice of Intent to Make a Motion. Documents that receive notice of proper Amending Motions (Certified Amending Motions) will be presented for action at the annual June Association Technical Meeting. At the meeting, the NFPA membership can consider and act on these Certified Amending Motions as well as Follow-up Amending Motions, that is, motions that become necessary as a result of a previous successful Amending Motion. (See 4.6.2 through 4.6.9 of Regs for a summary of the available Amending Motions and who may make them.) Any outstanding objection following action at an Association Technical Meeting (and any further Technical Committee consideration following successful Amending Motions, see Regs at 4.7) must be raised through an appeal to the Standards Council or it will be considered to be resolved.

VI. Step 3b: Documents Forwarded Directly to the Council. Where no Notice of Intent to Make a Motion (NITMAM) is received and certified in accordance with the Technical Meeting Convention Rules, the document is forwarded directly to the Standards Council for action on issuance. Objections are deemed to be resolved for these documents.

VII. Step 4a: Council Appeals. Anyone can appeal to the Standards Council concerning procedural or substantive matters related to the development, content, or issuance of any document of the Association or on matters within the purview of the authority of the Council, as established by the Bylaws and as determined by the Board of Directors. Such appeals must be in written form and filed with the Secretary of the Standards Council (see 1.6 of Regs). Time constraints for filing an appeal must be in accordance with 1.6.2 of the Regs. Objections are deemed to be resolved if not pursued at this level.

VIII. Step 4b: Document Issuance. The Standards Council is the issuer of all documents (see Article 8 of Bylaws). The Council acts on the issuance of a document presented for action at an Association Technical Meeting within 75 days from the date of the recommendation from the Association Technical Meeting, unless this period is extended by the Council (see 4.8 of Regs). For documents forwarded directly to the Standards Council, the Council acts on the issuance of the document at its next scheduled meeting, or at such other meeting as the Council may determine (see 4.5.6 and 4.8 of Regs).

IX. Petitions to the Board of Directors. The Standards Council has been delegated the responsibility for the administration of the codes and standards development process and the issuance of documents. However, where extraordinary circumstances requiring the intervention of the Board of Directors exist, the Board of Directors may take any action necessary to fulfill its obligations to preserve the integrity of the codes and standards development process and to protect the interests of the Association. The rules for petitioning the Board of Directors can be found in the Regulations Governing Petitions to the Board of Directors from Decisions of the Standards Council and in 1.7 of the Regs.

X. For More Information. The program for the Association Technical Meeting (as well as the NFPA website as information becomes available) should be consulted for the date on which each report scheduled for consideration at the meeting will be presented. For copies of the ROP and ROC as well as more information on NFPA rules and for up-to-date information on schedules and deadlines for processing NFPA documents, check the NFPA website (www.nfpa.org) or contact NFPA Codes & Standards Administration at (617) 984-7246.

A properly installed and maintained system should be free of ground faults. The occurrence of one or more ground faults should be required to cause a ‘trouble’ signal because it indicates a condition that could contribute to future malfunction of the system. Ground fault protection has been widely available on these systems for years and its cost is negligible. Requiring it on all systems will promote better installations, maintenance and reliability.

Sequence of Events Leading to Issuance of an NFPA Committee Document

Step 1 Call for Proposals

▼ Proposed new document or new edition of an existing document is entered into one of two yearly revision cycles, and a Call for Proposals is published.

Step 2 Report on Proposals (ROP)

▼ Committee meets to act on Proposals, to develop its own Proposals, and to prepare its Report.

▼ Committee votes by written ballot on Proposals. If two-thirds approve, Report goes forward. Lacking two-thirds approval, Report returns to Committee.

▼ Report on Proposals (ROP) is published for public review and comment.

Step 3 Report on Comments (ROC)

▼ Committee meets to act on Public Comments to develop its own Comments, and to prepare its report.

▼ Committee votes by written ballot on Comments. If two-thirds approve, Report goes forward. Lacking two-thirds approval, Report returns to Committee.

▼ Report on Comments (ROC) is published for public review.

Step 4 Association Technical Meeting

▼ “Notices of intent to make a motion” are filed, are reviewed, and valid motions are certified for presentation at the Association Technical Meeting. (“Consent Documents” that have no certified motions bypass the Association Technical Meeting and proceed to the Standards Council for issuance.)

▼ NFPA membership meets each June at the Association Technical Meeting and acts on Technical Committee Reports (ROP and ROC) for documents with “certified amending motions.”

▼ Committee(s) vote on any amendments to Report approved at NFPA Annual Membership Meeting.

Step 5 Standards Council Issuance

▼ Notification of intent to file an appeal to the Standards Council on Association action must be filed within 20 days of the NFPA Annual Membership Meeting.

▼ Standards Council decides, based on all evidence, whether or not to issue document or to take other action, including hearing any appeals.

The Association Technical 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 Association Technical Meeting that takes place at the NFPA Annual Meeting.

The Association Technical Meeting 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 an Association Technical Meeting. The following presents some of the main features of how a Report is handled.

The Filing of a Notice of Intent to Make a Motion. Before making an allowable motion at an Association Technical Meeting, 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 Association Technical Meeting.

Consent Documents. Often there are codes and standards up for consideration by the membership that will be noncontroversial and no proper Notices of Intent to Make a Motion will be filed. These “Consent Documents” will bypass the Association Technical Meeting and head straight to the Standards Council for issuance. The remaining documents are then forwarded to the Association Technical Meeting for consideration of the NFPA membership.

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 NFPA Conference & Expo, takes place in June of each year. A second Fall membership meeting was discontinued in 2004, so the NFPA Technical Committee Report Session now runs once each year at the Annual Meeting in June.

Who Can Make Amending Motions. NFPA rules also define those authorized to make amending motions. 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, the NFPA Regs should be consulted.

Action on Motions at the Association Technical Meeting. In order to actually make a Certified Amending Motion at the Association Technical Meeting, 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 Association Technical Meeting 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.

Hirschler, GBH InternationalRecommendation: Revise definitions to read as follows: 3.3.1* Foam. Fire-fighting foam, within the scope of this standard, is a stable aggregation of small bubbles of lower density than oil or water that exhibits a tenacity for covering horizontal surfaces. Air foam is made by mixing air into a water solution, containing a foam concentrate, by means of suitably designed equipment. It flows freely over a burning liquid surface and forms a tough, air-excluding, continuous blanket that seals volatile combustible vapors from access to air. It resists disruption from wind and draft or heat and flame attack and is capable of resealing in case of mechanical rupture. Firefighting foams retain these properties for relatively long periods of time. 3.3.1.1* Alcohol-Resistant Foam. Used for fighting fires involving water-soluble materials or fuels that are destructive to other types of foams. Some alcohol-resistant foams may be capable of forming a vapor-suppressing aqueous film on the surface of hydrocarbon fuels. 3.3.1.2* Aqueous Film-Forming Foam (AFFF) Concentrate. A concentrated aqueous solution of one or more hydrocarbon or fluorochemical surfactants that forms a foam capable of producing a vapor-suppressing aqueous film on the surface of hydrocarbon fuels. The foam produced from AFFF concentrates is dry-chemical compatible and is therefore suitable for use in combination with that agent. 3.3.1.3* Film-Forming Fluoroprotein (FFFP) Foam Concentrate.

Substantiation: The committee has added this new requirement to address when this type of foam might be used. Committee Meeting Action: AcceptNumber Eligible to Vote: 29 Ballot Results: Affirmative: 20 Negative: 6 Ballot Not Returned: 3 Deniston, H., Greenup, M., Voisine, P.Explanation of Negative: BAGOT, K.: There is not enough supporting documentation to allow the use of 1% foams in ARFF. The original submitter provided a USAF report from the 90’s which only had 3 test fires and no statistical validity. The USAF which sponsored that work did not even take any actions based on the results. BORDELEAU, P.: Per the reference ( P-19 precision metering and one percent AFFF large scale fire performance test Dated April 1992) which was supplied at the committee meeting held in Jan-Feb 2012 concerning 1% Foam. The standard used in the reference stated that the foam concentrate tolerance should be + or - 10% (+ or -.1). the correct concentration for all nozzles should be.9 and 1.1% not 1.0 and 1.3 as listed in the current edition of the revision. MATHESON, G.: The stated allowable foam concentration range of 1.0% to 1.3% seems arbitrary and does not allow for a level slightly below the nominal percent concentration as is done in 5.2.2* & 5.2.3. Also the wording of this proposal does not follow that in 5.2.2* & 5.2.3, as there is no differentiation between the allowable foam concentrations from a turret, hand line, etc. PHILLIPS, P.: Concerns regarding basis for the change. STEYN, D.: Data presented is not current (dates back to April 1992). This issue is not addressed in the MIL specification MIL-F-24385. TONNACLIFF, M.: The information presented at the meeting was not conclusive. The information was based on a report that was more than 20 years old and the data was not current. The data I feel was old and not significant enough to warrant a change in the standard. Also, there is not significant enough use of 1%.

Refractive index or conductivity readings of the test sample shall be compared to the calibration curve and the corresponding foam solution concentration read from the graph. 6.2.2.3.1 Portions of solution drained during the drainage test described in 6.3.2.2 shall be used as a source of test sample for the concentration determination. 6.2.2.3.2 Refractive index or conductivity readings of the test sample shall be compared to the calibration curve and the corresponding foam solution concentration read from the graph. A.6.2.2.3 Because of the high sensitivity of the conductivity meter, it is necessary to collect a larger sample of drainage before making the determination. This will allow for the variation in conductivity of the drained liquid caused by small changes in the chemical composition of AFFF solution as it drains over a period of time. The equipment used to determine concentration should enable the user to accurately measure whether the foam solution produced by proportioning equipment is within the tolerance specified in 5.2.2 and 5.2.3. Examples include one handheld refractometer— American Optical Co. Model No. 10430 or equivalent — or one handheld conductivity meter — Omega Model CDH-70 or equivalent. ATAGO Co. Ltd. Model No. N10, AO Model No. 10441, or equivalent showing 0–10 on the Brix scale is recommended to enable low readings given by AFFF solutions to be read easily. Conductivity meters should

have an automatic temperature compensation feature, and should measure a conductivity range of 0 - 199.9 µS/cm in a low scale, and 0 - 199.9 mS/cm in a high scale. However, low-range refractometers (e.g., 0–10 Brix) might not be able to provide a 100 percent concentration reading of the foam concentrate when using Method B.

Petit, Akron Brass CompanyRecommendation: Revise text to read as follows: 1/16 in. (1.6 mm) 3/32 in. (2.4 mm) inside diameterSubstantiation: The 1/16” (1.6 mm) opening in the valve can lead to misleading foam drainage data. For example, an experiment was conducted where 533 mL of water was placed into the 1600 mL foam sample container. This is the amount of liquid in the container for a foam of 3:1 expansion. The valve on the bottom of the container was opened, and the amount of time for 133 mL of liquid to drain out was recorded. 133 mL was chosen since it is the ¼ volume of 533 mL. The time required for 133 mL to drain out was 54 seconds. The minimum allowable per table 5.1 is 45 seconds. Therefore, it is possible for pure water to meet the ¼ drain requirement of 45 seconds listed in table 5.1 for Method ‘B’. Increasing the opening to 3/32” (2.4 mm) reduces the time required for the same volume to 22 seconds. Using this modification, it is not possible for pure water to pass the ¼ drain requirement of 45 seconds listed in table 5.1 for Method ‘B’.

The container shall then be placed on the balance. The total weight of the foam sample and container shall be determined to the nearest gram. The weight of the foam sample in the container shall be determined by subtracting the weight of the empty container from the weight of the container filled with the foam. The weight of the foam sample in grams shall be divided by 4 to obtain the equivalent 25 percent drainage volume in millileters.6.3.3.2.3 The foam sample container shall then be placed on a suitable support and a graduated cylinder placed below the drain spout. At 30-second intervals, the accumulated solution in the bottom of the foam sample container shall be drawn off into the graduated cylinder and the amount recorded. If the expected expansion ration is more than 5:1, then a 100 ml graduated cylinder shall be used to collect the drainage; if the expected expansion ratio is 5:1 or less, then a 250 ml graduated cylinder shall be used.

Insert new paragraph after 6.3.3.2.3: 6.3.3.2.x The foam sample container complete with any remaining foam will then be weighed to the nearest gram. The graduated cylinder used to record the drainage and the collected foam will then be weighed in the same manner.

The expansion of the foam shall be calculated by the following equation: Expansion=1600/(full weight)-(empty weight in grams) net weight of foam sample in gramsSubstantiation: As the document is currently written, the recording of the drainage data is delayed until after the foam sample container is dried and weighed. This frequently causes the 30 second and 1 minute readings to be missed. Weighing the foam sample container at the end of the test will not change the results and it will permit the recording of the 30 second and 1 minute drainage readings.

The following is a suggested method for evaluating the basic extinguishing capability of the foam fire-fighting system. This method can be used to determine fire fighting capability of systems that do not meet the requirements listed in NFPA 414. B.1.3.1 The resistance of the foam blanket to the fire is important. Wind plays a big role in the determination of this property and repeat results are difficult to obtain with an outdoor test. Another factor, but one easier to control, is the size of the fire area at the start of re-ignition. To standardize this, a short section of stovepipe 12 in. (30.5 cm) in diameter is dropped into the foam blanket like a cookie cutter. The foam is removed from the inside, and the fuel surface is ignited and allowed to burn for 1 minute before the stovepipe is removed. The rate of enlargement of the fire is then observed. A long period of confinement is desired. The delay period after end of foam application and start of re ignition can be varied, but for comparative tests, it must be kept constant. Burnback performance requirements can be referenced using Underwriters Laboratories Inc.
