1Report on Fire Suppression Research for High-Density Storage FacilitiesRoberta PiletteDirector, Preservation DepartmentYale University LibraryHosted by ALCTS The Association for Library Collections and Technical Services
2HD Library Facility vs Warehouse Solid shelves spaced 12”-18” apartNarrow aisles due to size of materials being retrievedLong-term, homogeneous collectionsWarehouseOpen rack shelvingLarge, open aisles to facilitate palletized delivery & retrievalShort-term, ever-changing materials
4Project Development June 2005 Informal gathering of preservation librarians to determine next stepsColumbia University Harvard UniversityLibrary of Congress University of ChicagoUniversity of Michigan Yale UniversityUniversity of Illinois-Urbana ChampaignThe informal gathering became an informal consortium
5Survey Results Identified 51 institutions with high density facilities Survey conducted February 2006; 51% respondedQuestions asked regarding:Type of facilityEnvironmental conditionsAge of facilityConstruction details regarding the roof, exterior & interior walls and overall size with regards to length, height, widthTier/shelving configurationWhat materials are stored in the facility and how storedSprinkler/fire suppression systems
6Survey 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%
7Survey Results Storage within the a module Fire Suppression systems Interfile format types within a module 54%Mixed formats within a section of shelving, the shelf, or within the range/aisle >33%Fire Suppression systemsIn-rack sprinklers 50%No in-rack sprinklers 50%
8Project Timeline July 2006 May 2007 Feb 2008 March 2010 June 2011 Survey results inMeeting at Yale to establish goals and expected outcomesMay 2007FMGlobal approves projectProject and testing design begins; research engineer assignedFeb 2008Update on first set of testsLessons learned & reaffirmation of goalsMarch 2010All testing completePreliminary results & recommendations presented to consortiumJune 2011Final Report
9Project GoalsProvide fire protection options for a typical high-bay, high-density storage arrangementDevelop loss mitigation methods to reduce non-thermal damageIf necessary, make recommendations for the future design of high density storage modules
10Terminology & Test Array Longitudinal flueAisleRackSprinkler heads Transverse flueOverhead view of the shelving arrangement for tests.
11The Tests Test #1 Test #2 Test #3 In-rack sprinklers at 10 & 19 ft level at each transverse &longitudinal intersectionCeiling sprinklersBooks in trays on shelvesTest #2Sprinklers same as #1Books in trays & Archive boxes on shelvesTest #3Sprinklers same as #1 BUT add face sprinklers at 10 & 19 ft level
12Results & ConclusionsSmoke 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.
13Other Findings Along the Way Narrow aisles make fire fighting difficultAmount of material affected even in a small incident is large—remember this is ‘high-density’
15Other 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
16Final Recommendations Early detection devices mean faster response and less damageIn-rack & ceiling sprinklers are good but adding face sprinklers provides the best protectionLocal fire department needs to be familiar with facility and its potential challenges and hazardsResponse & recovery plan are necessaryConsidering replacing corrugated trays with something that is non-combustible and will not fail when wet
