A flood in the library caused by a burst pipe.
An accidental fire sprinkler discharge resulting in a voluminous mist spraying down on bookshelves.
Heavy rains lead to an unexpected roof leak in the early hours of the morning.
These scenarios strike fear in the heart of any person working in libraries and archives as they think of precious collections potentially being damaged beyond repair. Unfortunately, these scenarios aren't just the stuff of bad dreams: a water disaster - big or small - can happen at the most unsuspecting of times.
