3. The Chair stated there were several purposes for this meeting; to receive updates on fire hose
research being conducted and to discuss upcoming revision of fire hose documents.
4. The minutes from February 12, 2013 and June 26, 2014 were accepted as written.
5. Bob Duval, NFPA provided a brief overview of the 2014 Back Bay Fire on Beacon Street. He
discussed other incidents including a fire in Keokuk, Iowa.
6. Briefing on fire hose research projects.
a. Casey Grant from the Fire Protection Research Foundation (FPRF) provided a brief
presentation on how that group can facilitate and participate in research. Slides from the
presentation are provided. [Attachment A]
b. Kathy Notarianni and Raymond Ranellone from Worcester Polytechnic Institute (WPI)
gave a briefing on their department’s Center for First Responder Technology and their
current fire hose research project.
c. Adam St. John and Lisa Herb from the Bureau of Alcohol, Tobacco, Firearms and

from the presentation are provides. [Attachment B]
d. Committee members and guests discussed the presentations and the need for further fire
hose research.
e. Kathy Crosby-Bell addressed the committee on the efforts of the Last Call Foundation to
support research on fire fighter safety issues.
7. Dan Gorham reminded the committee that NFPA 1961 is in the Annual 2017 revision cycle. The
closing date for Public Inputs is July 6, 2015 and the First Draft Meeting must occur before
December 14, 2015.
8. Discussion of NFPA 1961 revision topics
Carl Peterson raised possible issues for consideration for the next edition of the standard.
a. Friction loss research – As the current edition of NFPA 1961 was being finalized, the
FPRF report “Determination of Fire Hose Friction Loss Characteristics” was being
finalized. Does the standard need to address friction loss in fire hose more than it
currently does?
b. Is there a need for third party listing of fire hose? Some NFPA fire service product
standards currently require third party testing.
c. Consider more requirements on resistance to heat and flame impingement based on
outcome of current research.
9. Other Fire Hose Committee Documents: NFPA 1962, 1963, 1964, and 1965
Carl identified 3 pending items for the next editions of the other documents the committee is
responsible for.
a. Develop annex material for NFPA 1962 to help users understand what constitutes hose
and coupling failure
b. Combine NFPA 1964 and 1965 into a single document. January 5, 2016 is the first draft
closing date for NFPA 1964 which is the cycle the combination needs to occur in.
c. Address the force to connect and disconnect hydrant caps raised by a proposed TIA to
NFPA 1963
10. New or Other Business
a. Dennis LeGear suggested developing a numerical rating system for fire hose to assist in
evaluation for purchasing.

5.1.1 Fire hose shall have a Hazen-Wiliams coefficient of not less than 135.
Results of the FPRF fire hose friction loss research show that today's fire hose has low friction loss characteristics. Factory Mutual's fire hose approval standard 2111 uses the Hazen-Wiiliams constant of 135 in determining friction loss requirements. An interior roughness of 135 is equivalent in smoothness to a little less than polyethylene plastic pipe. Using 135 will be in line with the FM (and UL) approval standards for friction loss in fire hose and bring friction loss measurements of modern fire hose close to the actual friction loss experienced in fire ground operations. It should be noted that going back to 1967 the fire hose standard has never included a requirement for friction loss in the standards but discussed friction loss characteristics in general in the annex. I do not know when or why FM and UL included friction loss characteristics in their standards or where the 135 came from. Knowing FM, I assume they did testing to come up with 135. Regarding the use of the Hazen- Williams 135 in the field, it should be noted that pressure gauges on apparatus fire pumps are checked annually for accuracy and only have to be within 10 psi of calibration.

Public Input No. 4-NFPA 1961-2013 [ Section No. 5.6.1 [Excluding any Sub-Sections] ]
Each length of fire hose shall be indelibly marked in letters and figures at least 1 in. (25 mm) high with the manufacturer's identification, the country of origin hose origin , the month and the year of manufacture, and the words “service test to [the service test pressure] psi (bar) per NFPA 1962 [Standard for the Inspection, Care, and Use of Fire Hose, Couplings, and Nozzles and the Service Testing of Fire Hose].”
Additional Proposed Changes
Some manufacturers are importing hose, marking it "Made In USA" using the reasoning that the cost of the couplings and labor to attach such couplings exceeds the cost of the "hose" justifying the Made in USA markings. County of Origin would resolve this issue and clarify where the actual hose is made.

A.5.1.1
The friction loss characteristics of fire hoses are an important consideration in the selection of hose. Friction loss varies considerably depending on the construction and design of the hose, the roughness of the lining, and its internal diameter, which may be different for different grades of hose. The type of couplings can also affect the friction loss.
Where friction loss is important, side-by-side comparisons are recommended. The following test is recommended.
All comparative tests should use 300 ft (90 m) of each type of hose to be tested laid side-by-side on a level surface. Commercially available line pressure gauges should be installed at the inlet and the outlet of the first 300 ft (90 m) of hose to be tested.
A smooth bore nozzle of the size shown in Table A.5.1 should be used for the tests. Pressurize the test hose while the nozzle is fully open until a pitot gauge reading of the discharge reads 50 psi (3.5 bar). Read the pressure shown on the inlet and outlet line gauges. Subtract the outlet pressure from the inlet pressure and divide by 3 to determine the friction loss per 100 ft (30 m) of hose. Repeat the test for the next type hose to be tested. The hose with the lowest friction loss will flow the most amount of water for a given inlet pressure.

ATTACHMENT C
Fire Hose Performance Task Group
In 2010 through 2012, the Fire Protection Research Foundation conducted a research project on the friction loss in modern fire hose. A report on that research was published in April 2012 with revisions published in October, 2013. Currently NFPA 1961 has no requirements for maximum friction loss in fire hose and only briefly discusses it in Annex A.5.1. While that annex states “Where friction loss is important, side-by-side comparisons are recommended”, this is not practical in many fire departments that purchase small amounts of hose each year and do not have the capability to get standardized comparison data.
Friction loss in fire hose is a measure of performance but there are others. The Fire Hose Performance Task Group should develop criteria that are useful to the purchaser of fire hose as well as the user in the field in evaluating the expected differences in performance of fire hose, review relevant research aimed at evaluating performance, and make recommendations on how to measure and report such performance, whether through a grading system or some other standardized manner.
Fire Fighter Equipment Operational Environment Task Group
The environment in which the fire service operates when extinguishing fires has changed dramatically over the past several years due to new material of construction, contents of buildings and more aggressive tactics. The firefighter and his or her tools are a system, the weakest component of which is the limitation on the system. Fire fighters rely on water carried through fire hose and discharged through nozzles as a component of their protection.
The Task Group on Fire Hose Operational Environment should review current research on modern fire fighter operating environments to determine potential criteria for fire hose based on expected operating conditions. This Task Group should work with other technical committees responsible for equipment expected to operate in the modern firefighting environment. Initially this task group should focus on the structural fire fighting environment.
Possible committees to collaborate with:
FAE-SPF: Structural and Proximity Fire Fighting Protective Clothing and Equipment FAE-RPE: Respiratory Protection Equipment FAE-ELS: Electronic Safety Equipment
Fire Hose Test Procedures Task Group
The Task Group on Fire Hose Test Procedures should review NFPA 1961 for compatibility with the fire hose design, performance criteria, and test procedures in currently referenced test standards ANSI/UL 19 “Lined Fire Hose and Hose Assemblies” and FM Class 2111 “Lined Fire Hose and Hose Assemblies” as well as international standards including DIN 14811 “Fire- Fighting Hoses - Non-Percolating Layflat Delivery Hoses And Hose Assemblies For Pumps And Vehicles” and BS 6391 “Specification for non-percolating layflat delivery hoses and hose assemblies for fire fighting purposes”. In addition this task group should monitor developing or on-going research that could be used to evaluate fire hose performance to determine its application to the requirements in NFPA 1961.
Evaluation of Inspection and Service Test Results Task Group
NFPA 1962 covers the inspection and service testing of fire hose, couplings, nozzles, and fire hose appliances. The Task Group on Evaluation of Inspection and Service Test Results should review the document for wording that appears to leave no leeway but for a literal interpretation and develop guidance for the user if there is any tolerance permitted in interpretation of results. For example, 4.5.1 states “ Physical inspection shall determine if the hose and couplings have been vandalized, are free of debris, and exhibit no evidence of mildew, rot, or damage by chemicals, burns, cuts, abrasion, and vermin.” Paragraph 4.8.5.2.17.2 states “If the hose assembly shows any sign of coupling slippage, the hose assembly shall have failed the test.” Both of these can be subject to interpretation. Where appropriate, the task group should recommend guidance including artwork or photographs for inclusion in the Annex to assist the user in making an appropriate interpretation of the committee’s intent.
Task Group to guide the combining of NFPA 1964 and NFPA 1965
This task group should identify the common requirements and the unique requirements between NFPA 1964 and 1965, determine if some of the unique requirements should be broadened to apply to both spray nozzles and fire hose appliances, and make recommendations for consideration by the full committee for any changes. The task group should also develop a title, scope, and purpose for the combined document and propose a format for the combined document. It will be the intent to merge NFPA 1965 into NFPA 1964 and withdraw NFPA 1965 once that is completed.
