Call to Order. The Committee Chair, Joseph Fehr, called the meeting to order at 8:00 a.m. and presented the objective of the meeting, which is to review the use of interlock, trip, permissive, and related terms throughout chapters 1-4. 2. Introductions and Update of Committee Roster. The attendees introduced themselves and their affiliation, and the committee roster was acknowledged as part of the meeting agenda materials. 3. Staff Updates. The NFPA Staff Liaison, Laura Montville, gave general information on meeting procedures and revision cycle timelines in an opening PowerPoint presentation. She also reviewed Technical Committee appointments made at the August Standards Council meeting. Mary Elizabeth Woodruff gave a presentation (attached) on the data analysis and research services available to committee members through the Charles S. Morgan Library, the Fire Analysis and Research Department, and the Fire Protection Research Foundation. Committee members can contact research@ for more information. 4. Draft definitions for interlock, permissive, and trip. The Technical Committee discussed the draft definitions proposed by the Correlating Committee, and agreed upon the following language: Interlock: A function which prevents, limits, stops, or initiates the operation of equipment or a subsequent function. o Annex language: An interlock can consist of a sensing function, a control function, and an output or a final control element. The interlock can be accomplished with the use of any combination of electrical devices, mechanical devices, or logic.
Permissive: An interlock that functions only to allow initiation of the operation of equipment or a subsequent function Trip: An interlock that shuts down equipment when a predefined set of conditions exists. It was decided that permissive and trip should be subdefinitions under interlock, but they should also appear in alphabetical order with a reference back to the interlock section, similar to what is done for coal in 3.3.30. 5. Recommendations for other Chapters. The use of interlock and related terms was reviewed throughout Chapters 1-4, and the following recommendations were developed: Safety device, protective device, interlock device and safety interlock device appear to be synonymous. The Fundamentals Committee suggests using "interlocks" or "interlocks and associated devices" as appropriate. Safety function is similar to the new definition of an interlock. The Fundamentals Committee suggests using the term interlock. Master fuel trip device is not defined in Chapter 3, and is only used in Chapter 7 and its Annex. If this is intentionally different from a master fuel trip relay, it should be defined in Chapter 3. Otherwise, it should be replaced with master fuel trip relay. Safety shutdown is only used in Chapters 3, 4, and 5, and the Annex to Chapters 5 and 7. For consistency throughout the document, the Fundamentals Committee recommends replacement with trip or master fuel trip, as appropriate. The Fundamentals Committee will be removing the term from Chapters 3 and 4. Emergency shutdown is used in Chapters 4, 6, 7, 8, and 10, and the Annex to Chapters 4, 6, and 7, as well as Annex B. This appears to be the same as a safety shutdown, so the Committee recommends replacement with trip or master fuel trip as in the comment above. The Fundamentals Committee will be removing the term from Chapter 4. Abnormal shutdown is only used twice, both times in Chapter 6. This appears to be synonymous with trip and for consistency, that term should be substituted. 6. New Business. No new business was discussed. 7. Next Meeting. The next meeting will be scheduled after receiving feedback from the other NFPA 85 Technical Committees. The First Draft meeting will be held in early 2017. 8. Adjournment. The meeting adjourned at 3:10 p.m.

Role of the Foundation Plan, manage and communicate research in support of the NFPA mission Independent charitable organization Formed by NFPA in 1982 Intended to provide data to support the needs of NFPA codes & standards Research funds come primarily from: Private and public sector consortia Grants and government sources (e.g. DHS S&T, DOD, FEMA AFG, NIOSH, NIST, NSF, etc) Multiple other sources (including NFPA, e.g., Code Fund) How the Foundation operates I. Benchmarking state of the art symposia II. Agenda Setting research planning in emerging areas III. Research Programs Research projects to meet the needs of NFPA Committees and others Projects range from small literature search type studies to major fire testing programs 7
Project participants who are they? Funding (Sponsors): Where does it come from? Manufacturers, trade associations, NFPA, federal agencies, research organizations, nowhere, etc Contractors: Who Does the Work? Consultants, research organizations, test labs, universities, NFPA Fire Analysis, volunteers Advisory Oversight: Project Technical Panel Typically small (6 to 15) Meet at important stages of project (start/end/other) Underlying benefits of Foundation projects Independence Collaboration Cost sharing Credibility Pipeline to implementation Communications network The whole is greater than the sum of its parts - Aristotle WWW.NFPA.ORG/FOUNDATION 8
Background on NFPA Code Fund Characteristics: Intended to stimulate additional research Considered when lacking other obvious funding sources Funded directly by NFPA Annual evaluation process Focus on smaller one-year projects Code fund projects Blank form is available at: www./codefund Form is most helpful with efforts to package a particular project, no matter what funding venue is ultimately used. 9
