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.

A structure (s) or space other than the roadway usually used to house or contain operating, maintenance, or support equipment and functions. 3.3.43 Queue. A line of non-moving stored vehicles.Substantiation: Some ancillary facilities referred to in the document are not “stand alone” structures but are spaces that are apart or adjacent to the tunnel. Committee Meeting Action: AcceptNumber Eligible to Vote: 24 Ballot Results: Affirmative: 22 Ballot Not Returned: 2 Kroboth, III, J., LeBlanc, D.Comment on Affirmative: NELSEN, J.: I would suggest that this term should be “ancillary structure” rather than “ancillary facility” in keeping with the global attempt to differentiate between facilities, which contain a roadway and structures which do not. However doing so would also require making the same change in the following sections: 4.3.7* Ancillary Structures Facilities. All related ancillary structures facilities that support the operation of limited access highways, depressed highways, bridges and elevated highways, and road tunnels shall be protected as required by all applicable NFPA standards and applicable building codes except as modified in this standard. A.4.3.7 Protection of related ancillary structures facilities such as service areas, rest areas, toll booths and plazas, pump stations and substations, and buildings used for administration, law enforcement, and maintenance presents problems that basically do not differ from fire protection problems for all buildings. However, special consideration should be given to the fact that where located on, or adjacent to, limited access highways, such buildings can be located in isolated areas. (See NFPA 30 and NFPA 30A.) 12.3.1.1 All wiring installed in ancillary structures facilities shall not require additional physical protection as described in 12.3.1 provided that they are installed in a cable tray and are listed for cable tray use.

For road tunnels, bridges, and limited access highways, radio, telephone, and messaging throughout the facility. Emergency communications, where required, shall be by the installation of outdoor-type telephone boxes, coded alarm telegraph stations, radio transmitters, or other approved devices. A system for the protection of life by indicating the existence of an emergency situation and communicating information necessary to facilitate an appropriate response and action. 3.3.16.1 One-Way Emergency Communications System. One-way emergency communications systems are intended to broadcast information, in an emergency, to people in one or more specified indoor or outdoor areas. It is intended that emergency messages be conveyed either by audible, visible, or textual means, or any combination thereof. 3.3.16.2 Two-Way Emergency Communications System. Two-way emergency communications systems are divided into two categories, those systems that are anticipated to be used by building occupants and those systems that are to be used by fire fighters, police, and other emergency services personnel. Two-way emergency communications systems are used to both exchange information and to communicate information such as, but not limited to, instructions, acknowledgement of receipt of messages, condition of local environment, and condition of persons, and to give assurance that help is on the way. 3.X Emergency Communications System — Central Control Station. A mass notification system facility(s) with communications and control equipment serving one or more buildings where responsible authorities receive information from premises sources or systems or from (higher level) regional or national sources or systems and then disseminate appropriate information to a building, multiple buildings, outside campus areas, or a combination of these in accordance with the emergency response plan established for the premises. 3.XX Public Safety Radio Enhancement System.

Emergency communications, where required, shall be by the installation of outdoor-type telephone boxes, coded alarm telegraph stations, radio transmitters, or other approved devices. A.3.3.16 Emergency communications, where required, should be by the installation of outdoor-type telephone boxes, coded alarm telegraph stations, radio transmitters, or other approved devices (see 4.5).Substantiation: The NFPA Manual of Style requires definitions to be in single sentences. The added sentences should not be part of the definition (and in this case they are simply added explanations) but should be in the body of the document or in an annex note, as recommended in this proposal. In fact, section 4.5 has virtually the same language. Committee Meeting Action: Accept in PartThe committee Accepts the following:“3.3.16* Emergency Communications. For road tunnels, bridges, and limited access highways, radio, telephone, and messaging throughout the facility. Emergency communications, where required, shall be by the installation of outdoor-type telephone boxes, coded alarm telegraph stations, radio transmitters, or other approved devices.” The committee does not accept the addition of the following language:“A.3.3.16 Emergency communications, where required, should be by the installation of outdoor-type telephone boxes, coded alarm telegraph stations, radio transmitters, or other approved devices (see 4.5).”Committee Statement: The technical committee accepts the proposed language, however, rejected the inclusion of the proposed A.3.3.16 based on the fact that these same requirements are identified in 4.5.

(see 4.8) A material that, in the form in which it is used and under the conditions anticipated, will not ignite, burn, support combustion, or release flammable vapors when subjected to a fire or heat. Materials that are reported as passing ASTM E 136, Standard Test Method for Behavior of Materials in a Vertical Tube Furnace at 750°C, or other equivalent standards shall be considered noncombustible materials.4.8* Noncombustible Materials. A material that complies with any of the following shall be considered a noncombustible material: (1)* A material that, in the form in which it is used and under the conditions anticipated, will not ignite, burn, support combustion, or release flammable vapors, when subjected to fire or heat (2) A material that is reported as passing ASTM E 136, Standard Test Method for Behavior of Materials in a Vertical Tube Furnace at 750 Degrees C (3) A material that is reported as complying with the pass/ fail criteria of ASTM E 136 when tested in accordance with the test method and procedure in ASTM E 2652, Standard Test Method for Behavior of Materials in a Tube Furnace with a Cone-shaped Airflow Stabilizer, at 750 Degrees C. [5000:7.1.4.1.1] A.4.8 The provisions of 4.8 do not require inherently noncombustible materials to be tested in order to be classified as noncombustible materials.

Materials that are reported as passing ASTM E 136, Standard Test Method for Behavior of Materials in a Vertical Tube Furnace at 750°C, or other equivalent standards shall be considered noncombustible materials. Note: Tunnel fires may exceed 1200 C and test methods should reflect the potential temperature. A.3.3.37 Noncombustible Material. Standards other than ASTM E 136, Standard Test Method for Behavior of Materials in a Vertical Tube Furnace at 750°C, exist that are used to assess non-combustibility of materials.

A standard test that represents the potential temperatures found in the tunnel should be used.Substantiation: Most tests do not recognize the potential temperatures found in tunnels. Changing the definition is necessary to ensure designers/ engineers recognize the potential. Annex language change allows the currently listed tests for lower temperatures, but calls for use of a standard test that reflects the temperatures that might be found. Committee Meeting Action: RejectCommittee Statement: The technical committee acknowledges the standard test for the “temperature range” of concern does not exist.

Report on Proposals A2013 — Copyright, NFPA NFPA 502Comment on Affirmative: NELSEN, J.: Conceptually I agree with the action on this proposal however I would suggest the term “building” as defined in NFPA 5000, Building Construction and Safety Code, 2012 Edition may be more appropriate in this context. 3.3.69* Buildings. Structures, usually enclosed by walls and a roof, constructed to provide support or shelter for an intended occupancy. [ASCE/SEI 7:1.2.1] _______________________________________________________________ 502-27 Log #67 Final Action: Reject(3.3.43 Quantified Risk Assessment (QRA) (New) )_______________________________________________________________ Submitter: Ian E. Barry, IEB Consulting Ltd.Recommendation: Add a definition for Quantified Risk Assessment (QRA) - suggest inserting this in 3.3.43 using the following wording: 3.3.43 Quantified Risk Assessment (QRA) – is a Risk Evaluation used to identify specific operational risks and to select appropriate fire and life safety mitigation measures for any specific tunnel or facility. The current definition at 3.3.43 (Queue) moves to 3.3.44 and the remainder of the definitions follow chronologically. Substantiation: The Technical Committee has assigned Task Group 12 to address QRA’s and is committed to address this QRA issue during the current revision cycle. Committee Meeting Action: RejectCommittee Statement: The technical committee has determined that the definition of “Quantify Risk Assessment” is not necessary since the term itself is not used within the body of this document. Number Eligible to Vote: 24 Ballot Results: Affirmative: 22 Ballot Not Returned: 2 Kroboth, III, J., LeBlanc, D.Comment on Affirmative: BARRY, I.: The TC agreed that Quantified Risk Assessment should be considered by TG12 and incorporated into revised text concerning “Engineering Analysis” during the current revision cycle VAN DEN BOSCH, R.: The TC agreed that Quantified Risk Assessment should be considered by TG12 and incorporated into revised text concerning “Engineering Analysis” during the current revision cycle. _______________________________________________________________ 502-28 Log #56 Final Action: Accept(3.3.45 Rijkswaterstaat (RWS))_______________________________________________________________ Submitter: Arthur G.

English, Seattle Fire DepartmentRecommendation: Add new text to read as follows:4.2.1 Standpipe Installations in Tunnels Under Construction.*4.2.1.1 A standpipe system shall be installed in tunnels under construction in accordance with NFPA 241. 4.2.1.1.1 A standpipe system shall be installed before the enclosed tunnel has

exceeded a length of 61 m (200 ft) beyond any access shaft or portal and shall be extended as work progresses to within 61 m (200 ft) of the most remote portion of the enclosed tunnel. 4.2.1.1.2 Standpipes shall be sized for approved water flow and pressure at the outlet, based upon the maximum predicted fire load. 4.2.1.1.3 Reducers or adapters shall be provided and attached for connection of the contractor’s hose. 4.2.1.1.4 Reducers or adapters shall be readily removable through the use of a fire fighter’s hose spanner wrench. 4.2.1.1.5 Outlets shall be clearly identified with contrasting markings and with signs to readily identify the location in the tunnel and which standpipe is being used. 4.2.1.1.6 Outlets shall be readily accessible for fire department use. 4.2.1.1.7 Risers and outlets shall be protected from accidental damage. A.4.2.1.1 Tunnel Boring Machine cooling water may be used for the standpipe line provided this line is always charged and functional, and the pressures needed for standpipe outlets do not exceed pressure limits of the TBM. This may be achievable by using the return cooling line from the TBM with a double back flow preventer to prevent overpressuring the TBM. Substantiation: This was approved in the 2011 cycle, but left out of the document. Slight changes have been made to the text for clarity, and annex language added to clarify a potential use that saves the expense of installing a dedicated standpipe line. Committee Meeting Action: RejectCommittee Statement: The proposal does not match NFPA 241, Standard for Safeguarding Construction, Alteration, and Demolition Operations language. The technical committee recognizes the issues brought forth in this proposal and has generated 502-31 (Log #CP9) to more accurately address the requirements for standpipes in tunnels under construction in coordination with NFPA 241.
