Call to order. The meeting was called to order at 9:10 a.m. on January 20, 2015 by Technical Committee (TC) Chair, Dr. Christina Baxter. 2. Welcome & Introductions. Dr. Baxter welcomed everyone to the Second Draft meeting for NFPA 1991 and the First Draft meeting for NFPA 1992 and. Members and guests introduced themselves and their affiliation. Dr. Baxter thanked everyone for their participation in this meeting to address the public comments received on the first draft of NFPA 1991 and public input on NFPA 1992 and. She outlined the plan for this meeting. 3. Approval of Minutes. The minutes from the NFPA 1991 First Draft meeting held on September 30 October 1, 2014 in Dallas/Fort Worth were approved by the TC. 4. NFPA Staff Report and Discussion of Document Revision Process. The NFPA Staff Liaison, Mr. Dave Trebisacci, provided general information on NFPA procedures and timelines in an opening presentation. He addressed NFPA antitrust and patent policies to be adhered to as well as composition and balance of the TC. Mr. Trebisacci stated that the Hazmat TC is in balance. All principal members should designate an alternate member if they have not already done so. NFPA 1991 - Mr. Trebisacci noted that NFPA 1991 is in the fall 2015 cycle and is expected to be on the NFPA Standards Council agenda for approval in November 2015. If approved, NFPA 1991 will carry a 2016 cover date. NFPA 1992 and - Additionally, Mr. Trebisacci reminded the TC that NFPA 1992 and NFPA 1994 are in the fall 2016 revision cycle. The Public Input stage of the revision process closed January 5, 2015. A second draft meeting will need to be held between November 2015 and January 2016. 2
5. Actions on Public Comments to NFPA 1991. Actions that can be taken on the comments are to (1) Accept, (2) Reject, but see related SR, (3) Reject and (4) Reject, but hold. It was noted that any public comments that are determined to be a hold will automatically become Public Input for the next revision to NFPA 1991. Dr. Baxter discussed her review of the comments received and noted that 75% of the comments could be addressed in certain groupings. Issue groupings addressed were: Encapsulating Vs. Non- Encapsulating, Cumulative Permeation vs. Breakthrough Time, MIST vs. SF6, Visor Impact, Flame Melt vs. Drip, Field of Vision, Single Layer, Flame Break Open Resistance. During the October 2014 TC meeting, the committee developed an approach which merged the cumulative permeation and breakthrough time measurements. Changes were made throughout the document to address the approach for all chemical permeation testing. Endpoints were finalized. Based on round robin testing conducted since October 2014, values for the MIST performance requirements were established to address the gap left from elimination of the SF6 test. It was agreed that the appropriate respiratory protection for NFPA 1991 is NIOSH certified CBRN SCBA that is also certified to NFPA 1981. Revised criteria was incorporated from public comments for cut resistance and puncture resistance. The new ASTM F2913 will be used for slip resistance testing. New tests for visor high mass resistance and puncture resistance replace old methods. Replacement methods for testing footwear toes and footwear soles and heels were added. The TC decided to move all proposed requirements for non-encapsulating ensembles to a new Class 1 contained in. Therefore, NFPA 1991 will not contain any non-encapsulating ensemble performance or test requirements. A master response was created to address the substantiation for this action. Suit closure systems were discussed in great detail, and it was decided to include an Annex item to address limitations of current closure technology to educate the end users. Currently the technology does not exist for testing of closures. Inclusion of a test for flame break open resistance was put on hold to allow for manufacturer garment testing and test laboratory validation. Storage life will now be required to be stated in years with the date of manufacture as a basis. A field of view performance requirement was finalized. It was decided that testing across laboratories needs to be conducted with test garments as worn to incorporate a test in the next revision to address prediction of body burn. A standard table format was finalized for reporting compliance information as part of technical data requirements. 3
6. NFPA 1992 Public Input Review. Following extensive discussion, the TC agreed to the importance of maintaining the ability to certify ensemble elements. Language relating to requirements, including definitions, for hoods will be incorporated throughout the standard. In discussing the intent to have NFPA 1992 address materials that are known or suspected human carcinogens, it was decided to include language in the Annex and call attention to the need to conduct a risk assessment for selection/use based upon the hazard. With regard to the definition of bootie, it was generally agreed to change this to emphasize the use of a bootie is intended to be worn inside of a boot. Other high level issues addressed include the potential addition of Evaporative Resistance as an indicator of breathability, incorporation of a new chemical battery, non-encapsulating language, changes to requirements relating to permeation vs. penetration resistance in 7.1.3, the Overall Heat Transfer Performance Test, a fatigue procedure for suit closure assemblies, incorporation of changes relating to visors per NFPA 1991 and specification of the respirator during certification testing. A proposed list of chemicals was developed for section 8.4.4.1 for use in the chemical penetration resistance testing. 7. Public Input Review. Discussion occurred on the scope section of the standard to ensure the HazMat operations are addressed in the standard. It was suggested that the title may need to be revised as well. It was also mentioned that garments have been submitted for Class 4, and, therefore, requirements for this class should be maintained. 8. Next Meeting. The next meetings of the Hazmat PC&E TC will be held as teleconferences on January 30, February 4, 6, 13, 16 and 17, 2015. 9. Adjournment. There being no further business before the TC, the meeting adjourned. Respectfully submitted by: Patricia Gleason Secretary NFPA Haz Mat PC&E TC 4
30 January 2015 Teleconference 0900 1200 NFPA 1991 A review of NFPA Table 5.3.1.2 was completed for inclusion in NFPA 1991. There were no other comments from the TC to address. NFPA 1992 The draft, proposed chemical battery prepared at the TC meeting in San Diego was reviewed and modified for inclusion as a committee comment. Testing laboratories will need to provide further input on any testing issues or safety concerns with the proposed list of chemicals, especially Nitric Acid. Manufacturers will also need to conduct preliminary testing to provide the TC feedback on their results. Language was provided to clarify tests in Section 8 for hoods and interfaces to incorporate in NFPA 1991 & NFPA 1992 as needed. Public Inputs were reviewed by the TC in sequential order and updated sections were discussed. 4 February 2015 Teleconference 0900 1200 NFPA 1991 Chapters 5, 6, 7 & 8 were sent to the TC for a final review prior to today s meeting. Clean-up edits were completed by the TC. NFPA 1992 Issues were addressed regarding protective hood elements in sections 6.7. and 7.7. The TC agreed to move forward with changes to the shower test in 8.2 and the overall integrity test in 8.3. Various options were discussed for chemical penetration resistance in 8.4. Additional language was added to address testing closure assemblies with fatigue, testing hood materials after flexing and abrading and testing interface gasket materials. Ten chemicals were kept in the table in 8.4.4.1. Nitric Acid was deleted and Sodium Hydroxide was added. It was suggested that the CAS No. s and concentrations be listed. The annex will provide explanatory information on how the chemicals were chosen. A review of Public Inputs was initiated to allow for consistent actions to be taken as a result of decisions made for NFPA 1991 and NFPA 1992. 5
6 February 2015 Teleconference 0900 1200 A table was provided as the basis for review of Public Inputs remaining to be addressed. The TC discussed the Scope and modifications to the title and Chapter 1. The proposed title is Protective Ensembles for First Responders to Hazardous Materials and CBRN Terrorism Incidents. It was decided that a table should be included in the Annex to specify what each of the Haz Mat standards address to compare the property that is evaluated, the test method and measurement used and the performance criteria for each standard. A draft will be provided for the next conference call. For section 5.1.1.9 it was decided to add the total heat loss (THL) Value to the label and break out into 3 components for consistency, i.e. THL, conductive transfer resistance (RCT) and evaporative resistance (RET). A First Revision will be drafted for 6.2.7 for the TC to review. A First Revision will also be drafted for 6.4.10 to address the booties v socks issue. 13 February 2015 Teleconference 0900 1200 NFPA 1991 An additional review of NFPA 1991 found errors in 7.3 and 7.5 which were discussed and corrected per the agenda for this call. Chapter 8 Public Inputs were reviewed with the goal of maintaining consistency across the project. Concentrations and PAD locations for the MIST test were revised accordingly. Modifications to the liquid tight integrity test were completed. Additionally, more details were provided on the analytical techniques used in permeation testing to correlate with NFPA 1991. Interface gasket material references were incorporated. For the particle inward leakage test it was determined four specimens of any size and two test subjects will be used. Discussion on a new DoD TOP aerosol method for this test concluded with additional information should be provided to the TC prior to further action. It was noted that the full test method will be needed for the second revision step in the cycle. It was decided that correlation testing should occur between certification labs due to high reactivity issues in test conditions and repeatability issues with the test method used for certain challenge chemicals referenced in 8.7.6.3. Necessary language can be drafted based on results. A table will be added to the Annex to explain concentrations used for the various Classes. With regard to elimination of flexing requirements in 8.7.13.4 &.5, the Testing Task Group was requested to explore viable methods for flexing. 6
It was generally agreed that total heat loss of the certified ensemble is an important performance attribute, and ensemble testing using a thermal mannequin will be incorporated into the draft. The ensemble shall include all elements which were required to meet the protection requirements of the standard such as, but not limited to, garment, respirator, gloves, and boots. It was decided to include Requirements for Total heat loss of the certified ensemble for Classes 2 (when claiming breathability only), 3 & 4 including all elements which were required to meet the protection requirements of the standard. The manufacturer will select one representative certified ensemble configuration for this testing. 16-17 February 2015 Teleconference 0900 1200 NFPA 1992 Additional corrections were made to NFPA 1992 in sections 5.1.7, 6.4.4.1, 6.5.5.1 and 7.1.25, 7.6.3 for consistency with NFPA 1991. The TC reviewed the 21 chemicals from NFPA 1991 and TIC s to be incorporated in the Class 1 battery. The TC discussed the need for operationally relevant chemicals and the challenge to obtain consistent data. Following extensive discussion a revised table was drafted. Also discussed were the inclusion of several optional tests including audible signature (NIJ), color (NIJ) and flash fire. 7
