      • 6 to 8 minutes to isolate water with approximately 25,000 litres of water infiltrating floors
      • Emergency Evacuation Plan was instigated
      • Disaster Recovery Plan instigated to include protection of collections and removal of flood water from building
    • Damage to Collections
      • Some 4000 books affected by the flood
      • Thousands of manuscript items were laid out to dry
      • Overview of air drying material in reading room
      • 516 Items required conservation treatment
      • Boxing of collections protected items from flood
    • Drying methods
      • Interleaving
      • Air drying
      • Wind Tunnels
      • Material with coated paper were bagged and frozen
    • Damage to Building
      • Some 25,000 litres of water cascaded through the building
      • Water entered from level 12 and cascaded to level 2 ground floor
    • Residual Moisture Investigation
      • Consultant engaged to establish damage
      • Moisture mapping of affected areas took place
      • Residual moisture measured
      • Mycoflora and environmental monitoring
      • Contact samples of moulds
    • Residual Moisture Investigation
      • There was water damage from level 12 through to ground floor
      • Floor coverings were lifted to determine residual moisture at surface and 40mm depth
      • Moisture levels high
    • Residual Moisture Investigation
      • High moisture levels could lead to potential problems of infestation by microorganisms to books
    • Recommendations
      • Dry out masonry to acceptable levels
      • Use oil filled radiators and oscillating fans to introduce gentle heating and ventilation
    • Recommendations
      • Closely monitor flood damaged areas for mould infestation
      • Closely monitor environmental conditions
      • Install Air movers on all floors
    • Discovery of Toxic Mould
      • Toxic mould (Stachybotrys chartarum)
      • Confined to level 8 strongroom area
      • Infected area was sealed
      • Boxed material was vacuumed and moved to a holding area
      • PPE was worn at all times
    • Discovery of Toxic Mould
      • Dr Singh recommended a specialist company expert in toxic mould removal to remediate the area
    • Action taken
      • Company established plan to remove the mould and reinstate the affected area
    • Risk assessment
      • Toxic mould presented an obvious health risk which could only get greater if not treated
      • Danger of infecting the collections
      • Danger of infecting the building
    • Action taken
      • Fire retardant polythene enclosure constructed to encompass the areas of contamination
      • Shelving was removed before cleaning and reinstatement
      • Smoke extraction fans provided adequate negative pressure to suppress spores
    • Action taken
      • Operatives were required to wear specialist respiratory protective equipment providing organic and dust protection
      • Affected areas were treated with ‘Jati’ mould remover
      • Further one metre of flooring was removed to ensure mould had not spread
    • Action taken
      • All contaminated flooring and walls were removed and sprayed with the mould remover before being double bagged
      • The waste was carefully removed at set times to reduce the contact with staff and keeping to routes avoiding contact with collection material
    • Action taken
      • Once all mould contamination had been removed the area was then subject to two atmospheric decontaminations using the mould remover through an atomising device
      • This was to ensure that any airborne spores were removed
      • Finally the area was then cleared of plant and materials and subject to a final clean
