  1. Report on Fire Suppression Research for High-Density Storage Facilities Roberta Pilette Director, Preservation Department Yale University Library Hosted by ALCTS The Association for Library Collections and Technical Services

  2. HD Library Facility vs Warehouse HD Library Facility • Solid shelves spaced 12”-18” apart • Narrow aisles due to size of materials being retrieved • Long-term, homogeneous collections Warehouse • Open rack shelving • Large, open aisles to facilitate palletized delivery & retrieval • Short-term, ever-changing materials

  3. HD Library Facility vs Warehouse

  4. Project Development • June 2005 • Informal gathering of preservation librarians to determine next steps Columbia University Harvard University Library of Congress University of Chicago University of Michigan Yale University University of Illinois-Urbana Champaign • The informal gathering became an informal consortium

  5. Survey Results • Identified 51 institutions with high density facilities • Survey conducted February 2006; 51% responded • Questions asked regarding: • Type of facility • Environmental conditions • Age of facility • Construction details regarding the roof, exterior & interior walls and overall size with regards to length, height, width • Tier/shelving configuration • What materials are stored in the facility and how stored • Sprinkler/fire suppression systems

  6. Survey Results • What is stored and how • Bound items directly on shelf 68% • Mss & archival collections, non-plastic containers 88% • Analog audio disks, mechanical recordings, non-plastic containers 54% • Microfilm/fiche, non-plastic containers 47% • Magnetic media in trays on shelf 67% • Oversize maps & drawings in flat files & shelves 56%

  7. Survey Results • Storage within the a module • Interfile format types within a module 54% • Mixed formats within a section of shelving, the shelf, or within the range/aisle >33% • Fire Suppression systems • In-rack sprinklers 50% • No in-rack sprinklers 50%

  8. Project Timeline • July 2006 • Survey results in • Meeting at Yale to establish goals and expected outcomes • May 2007 • FMGlobal approves project • Project and testing design begins; research engineer assigned • Feb 2008 • Update on first set of tests • Lessons learned & reaffirmation of goals • March 2010 • All testing complete • Preliminary results & recommendations presented to consortium • June 2011 • Final Report

  9. Project Goals • Provide fire protection options for a typical high-bay, high-density storage arrangement • Develop loss mitigation methods to reduce non-thermal damage • If necessary, make recommendations for the future design of high density storage modules

  10. Terminology & Test Array Longitudinal flue Aisle Rack Sprinkler headsTransverse flue Overhead view of the shelving arrangement for tests.

  11. The Tests • Test #1 • In-rack sprinklers at 10 & 19 ft level at each transverse & longitudinal intersection • Ceiling sprinklers • Books in trays on shelves • Test #2 • Sprinklers same as #1 • Books in trays & Archive boxes on shelves • Test #3 • Sprinklers same as #1 BUT add face sprinklers at 10 & 19 ft level • Books in trays & Archive boxes on shelves

  12. Results & Conclusions • Smoke detectors in all tests went off prior to the first sprinkler head release. • The combination of in-rack and ceiling sprinklers provides adequate fire protection. • Additionally, in-rack sprinklers are effective in reducing the temperature of the racks thereby limiting the possibility of rack collapse. • Byadding face sprinklers it is estimated that there is 50% less damage to materials due to fire and water.

  13. Other Findings Along the Way • Narrow aisles make fire fighting difficult • Amount of material affected even in a small incident is large—remember this is ‘high-density’

  14. Slides from FM Global tests

  15. Other Findings Along the Way • Cardboard trays failed quickly • -Create falling book hazard • -Front of tray with barcode info is lost • -Weakened trays could not be used to pull books off shelf

  16. Final Recommendations • Early detection devices mean faster response and less damage • In-rack & ceiling sprinklers are good but adding face sprinklers provides the best protection • Local fire department needs to be familiar with facility and its potential challenges and hazards • Response & recovery plan are necessary • Considering replacing corrugated trays with something that is non-combustible and will not fail when wet

  17. Many thanks to David Fuller, Kristin Jamison & Mary Breighner at FMGlobal; Tom Gaitley at Copper Harbor Consulting, Inc; and fellow consortium members on this project.For copies of the FM Global report contact:David Fullerdavid.fuller@fmglobal.com Thank you roberta.pilette@yale.edu
