A malfunctioning sprinkler head reduced some historical documents kept in Columbia (USA) by the Missouri State Historical Society to waterlogged paper and soggy cardboard on October 1st, 2009.
Columbia firefighters arrived after receiving a report of a fire alarm sounding in the library and they have found the source of the alarm to be an activated sprinkler head in a storage room. The room was used to hold documents, in the lower level of the library.
Probably, it was some sort of mechanical failure in the head of the sprinkler system, which did cause water discharge. Firefighters shut off the sprinkler head and began cleaning the storage room. “In some cases, they may not be salvageable,” Executive Director Gary Kremer said.
Three shelves of books and documents were soaked. No one was in the room when the sprinkler head was triggered. “If the same system of sprinklers is throughout the facility, there are rooms — for example our art gallery — has tens of millions of dollars of artwork in it,” Mr Kremer said. “If the sprinklers were to malfunction there, that would be a catastrophe.”
