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
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
Project Development June 2005 Informal gathering of preservation librarians to determine next steps Columbia UniversityHarvard University Library of CongressUniversity of Chicago University of Michigan Yale University University of Illinois-Urbana Champaign The informal gathering became an informal consortium
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
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%
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%
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
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
Terminology & Test Array Longitudinal flue Aisle Rack Sprinkler heads Transverse flue Overhead view of the shelving arrangement for tests.
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
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. By adding face sprinklers it is estimated that there is 50% less damage to materials due to fire and water.
Other Findings Along the Way Narrow aisles make fire fighting difficult Amount of material affected even in a small incident is largeremember this is high-density
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
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
