Mr. Devlin noted the spelling of Schirmer Engineering was incorrect. The mistake will be corrected. 4. Fire Protection Research Foundation Project Review. Bill Koffel and Diana Hugue from Koffel Associates gave a presentation on the project Quantifying Smoke Barrier Performance. This project was initially proposed by the BLD/SAF-FIR Technical Committee during the ROC meeting in the Fall of 2007 and was conducted by the Fire Protection Research Foundation. See attachment A - Pg. 4. 5. Standardization of Language Where Supervision of Sprinkler Systems Is Required. The committee addressed this issue and no further action was taken. 6. Consistency of List Based Options i.e., when all conditions must be met or some conditions must be met. A task group was formed to address the sections

Quantifying Smoke Barrier Performance William E. Koffel, P.E., FSFPE Diana E. Hugue, P.E. Koffel Associates, Inc. In conjunction with The Fire Protection Research Foundation Overview Scope: Provide a literature review regarding quantifying the performance of penetrations of smoke barriers to include: Code change proposals Codes and standards Additional resources Provide a review of existing or proposed test methodologies concerning smoke barriers Provide recommendations for additional research 1
Smoke Barriers NFPA 101 Section 3.3.20 Barrier, Smoke : A continuous membrane, or a membrane with discontinuities created by protected openings, where such membrane is designed and constructed to restrict the movement of smoke. Smoke Barrier Penetrations 2
Background UL 1784, Air Leakage Tests of Door Assemblies Acceptance criteria = 3 cfm/sq ft of door opening 1991 Life Safety Code Allowed openings up to 20 sq in. in the lower half of corridor walls in health care occupancies Subsequently increased to 80 sq in. in smoke compartments protected with automatic sprinkler protection Smoke Barriers NFPA 101 Section 3.3.20 Barrier, Smoke : A continuous membrane, or a membrane with discontinuities created by protected openings, where such membrane is designed and constructed to restrict the movement of smoke. Duct penetrations addressed Door openings addressed in various ways Through penetrations not addressed 2009 IBC Background 3
Recent Code Development Activity Proposal 101-181 Limit combined leakage rate in a smoke barrier to 0.75 cfm/ sq ft of total wall area at 0.1 in. water column Based on permitted leakage for doors and opening limitation Recent Code Development Activity Proposal 101-187 Require materials sealing penetrations to be listed for restricting transfer of smoke No values given 4
Additional Resources NFPA 105, Recommended Practice for the Installation of Smoke-Control Door Assemblies NFPA 12A, Standard d on Halon 1301 Fire Extinguishing Systems, Annex B Principle of Smoke Management, J. Klote and J. Milke 5
Test Methodology Air Pressurization ASTM E779-03 Standard Test Method for Determining Air Leakage Rate by Fan Pressurization Overall building air leakage Determines tightness of building envelope Test Methodology Sound Meters An Acoustic Method of Leak Flow Measurement By C. Lin, S. Wtki Watkins, and dw. Walker Looked at circular leak holes in piping under various pressure conditions and pipe materials Test Methodology Other ASTM E1186 03 Standard Practices for Air Leakage Site Detection in Building and Air Barrier Systems Smoke Leakage Through Wall Openings in a Fire, W. Chan-Wei, et. al. Environmental Tobacco Smoke Leakage from Smoking Rooms, J. Wagner, et. al. 6
Test Methodology Other US Patent 5535253 Method and device for detecting leaks in penetrations of a nuclear reactor vessel head during operation ASTM E547 97 Water penetration of exterior windows, curtain walls, and doors by cyclic static air pressure differential An Air Barrier System in Cambridge, M. MeLampy, et. al. Determining the Criteria Leakage of individual penetrations Simple to determine Uses cold smoke Current approach for dampers, doors, and when addressed, through penetrations Total wall-leakage criteria Technically more valid Enforcement difficult Is it acceptable to merely require the design to comply? Must the actual assembly, as constructed, meet the criteria? 7
Determining Test Methods Depends on whether individual penetrations are to be considered or the barrier as a whole Type of smoke? Temperature Particulates Inconsistencies between current test criteria Future Research CFD Modeling for typical smoke barrier assemblies Use leakage values for individual penetrations Sound or infrared test methods 8
