Substantiation: Fiberglass-reinforced tanks are allowed by the standard, so they should be included in the list of permitted materials. See also our proposal regarding a new chapter of the standard to handle the rules for using such tanks. Committee Meeting Action: Accept Number Eligible to Vote: 18 Ballot Results: Affirmative: �4 Ballot Not Returned: 4 Hochhauser, D., Mitchard, J., Mow, B., Rosenwach, A. _______________________________________________________________ 22-4 Log #7 Final Action: Accept in Principle (4.3.2 and Chapter 11) ________________________________________________________________ Submitter: Kenneth E. Isman, National Fire Sprinkler Association Recommendation: Move all of 4.3.2 to a new Chapter �� as follows and renumber the existing Chapter �� through �6 as Chapter �2 through �7. Chapter �� Fiberglass-Reinforced Plastic Tanks ��.� Fiberglass-reinforced plastic tanks shall be permitted to be used for fire protection systems when installed in accordance with the rules of this standard, including this chapter. ��.2* Fiberglass-reinforced plastic tanks shall only be permitted for underground storage of water at atmospheric pressure. ��.3 Fiberglass-reinforced plastic tanks shall meet the requirements of AWWA D�20, Standard for Thermosetting Fiberglass-Reinforced Plastic Tanks. ��.4 Protection of Tanks. ��.4.� Tanks shall be located completely below the frost line to protect against freezing. ��.4.2 Where protection from frost is not a factor, the tank shall be buried in accordance with ��.4.2.� through ��.4.2.3. ��.4.2.� The tank shall be buried with a minimum depth of cover of at least 0.8 m (2.5 ft) to prevent mechanical damage. ��.4.2.2 The tank shall be buried with a minimum depth of cover of 0.9 m (3 ft) below driveways and parking lots. ��.4.2.3 The tank shall be buried with a minimum depth of cover of �.2 m (4 ft) below railroad tracks. ��.4.3 The depth of cover shall be measured from the top of the tank to the finished grade and due consideration shall be given to future or final grade and the nature of the soil. ��.5 At least 305 mm (�2 in.) of pea gravel, crushed stone or sand shall be backfilled around the tank. ��.6 If the tank is not installed above the maximum ground water level, suitable methods of anchoring the tank shall be permitted so that the buoyancy of the tank when empty do not force it upward.

��.7 The tank shall be designed to resist the pressure of earth against it. ��.8 Tank Connections. ��.8.�* Tanks shall have a vent that extends above ground to prevent against pressurization of the tank during filling and creation of a vacuum during use. ��.8.2* Tanks shall have an indication above ground of the level of water in the tank. ��.8.3* Tanks shall have an accessible method of filling the tank above ground. ��.8.4* Tanks that are used as cisterns for providing fire flow to fire department apparatus shall have a dry hydrant assembly with threads acceptable to the authority having jurisdiction. ��.9 Tanks used as cisterns for providing fire flow to fire department apparatus shall be located such that the lowest water in the tank used for fire protection is not more than 4.6 m (�5 ft) below the grade where the fire department apparatus will site to extract water out of the tank. A.��.2 Fiberglass tanks are only permitted to be used for underground water storage because of concerns over combustibility and damage. While it is difficult to get fiberglass tanks to burn while they are full of water, the potential would exist with an aboveground tank for a fire exposure to potentially damage the tank and compromise fire protection. More importantly, fiberglass tanks above ground could suffer structural damage after being struck. Placing the tank below ground eliminates these concerns. See Figure A.��.2 for an example of a fiberglass tank being used underground as a cistern to supply fire flow for fire department apparatus in a rural area.

Figure A.��.2 Fiberglass tank as an underground cistern. A.��.8.� See Figure A.��.8.� for an example of a combination vent and sight assembly, which allows the tank to stay at atmospheric pressure while allowing the user to know the water level in the tank. While these two devices are not required to be combined, it is convenient since they are both required to be above ground.

Substantiation: The rules of fiberglass tanks are currently in 4.3.2, which is inappropriate. Chapter 4 is general information that is supposed to apply to all tanks. Since all other tank materials have a chapter telling the user what to worry about when using that material to make the tank, fiberglass tanks should be the same. In writing the new chapter, new material was added to provide better guidance to the user for issues to consider when using a fiberglass tank for private fire protection. The new information fits better into a new chapter than it would have in the existing Chapter 4. In writing the new chapter, the term “fiberglass” has been changed to “fiberglass-reinforced plastic tank” in the body of the standard. This appears to be more consistent with the product that is being permitted by the standard. We recognize that this will be a very short chapter. But it will still be longer than existing Chapter �6 (one section) making it the second shortest chapter in the book. The following is separate substantiation for each new section in the new chapter: ��.� Establishes that fiberglass tanks are permitted to be used, which is a frequently asked question and needs to be addressed by the standard. ��.2 A rewrite of existing 4.3.2. ��.3 A rewrite of existing 4.3.2.�. ��.4 A new heading to consolidate some protection issues. ��.4.� A rewrite of existing 4.3.2.�.�. ��.4.2 (and its subsections) These rules were taken from NFPA 24 (�0.4.2 through �0.4.5). There needs to be some consideration to how deep to bury the pipe in climates where freezing is not a problem. There still needs to be some protection from mechanical damage, especially where heavy objects may roll over the surface above the tank. ��.4.3 is necessary to standardize the measurement of how far below the surface the tank will be. There needs to be some requirement to consider how the grade will be finished and how the soil might settle over time. This rule is also adapted from NFPA 24 regarding underground pipe. ��.5 is rewritten from 4.3.2.�.2 in the current standard. ��.6 is rewritten from 4.3.2.�.3 in the current standard. ��.7 is rewritten from 4.3.2.�.4 in the current standard. ��.8 (and its subsections) are common sense items that need to be added to the standard. While other tanks need similar connections, these rules need to be in this location to make it clear that these connections need to be above ground. ��.9 is added to the standard to make clear to users that there is a maximum

capability for fire department pumpers to draw water up into a centrifugal pump. A large tank buried too deep will prevent the fire department from using water towards the bottom of the tank. Annex material has been added to clarify the intent of the text in the body. The figures were taken from Figures A.9.4(f) and A.9.4(g) of NFPA ��42. Committee Meeting Action: Accept in Principle Revise text to read as follows: Chapter 11 Fiberglass-Reinforced Plastic Tanks 11.1 Fiberglass-reinforced plastic tanks shall be permitted to be used for fire protection systems when installed in accordance with the rules of this standard including this chapter. 11.2* Fiberglass-reinforced plastic tanks shall only be permitted for underground storage of water at atmospheric pressure.

(“Consent Documents” that have no certified motions bypass the Technical Committee Report Session and proceed to the Standards Council for issuance.)

▼ NFPA membership meets each June at the Annual Meeting Technical Committee Report Session 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 Technical Committee 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 Committee Report Sessions that take place at the NFPA Annual Meeting.

The Technical Committee 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 Committee 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 Safety Conference and Exposition®, 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. Those authorized to make these motions are 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 Committee 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 Committee Report Session.

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 Technical Committee Report Session and head straight to the Standards Council for issuance. The remaining Documents are then forwarded to the Technical Committee Report Session for consideration of the NFPA membership.

Action on Motions at the Technical Committee Report Session. In order to actually make a Certified Amending Motion at the Technical Committee 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, recommended practice or guide. Subject only to limited review by the NFPA Board of Directors, the decision of the Standards Council is final, and the new NFPA document 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.
