Recovery of the dried film depends on the extent of damage and how much
moisture it was exposed to and what format film was flooded.
If it is reels of silver film and it was soaked with water, the layers
of wound film re-adhered to both sides, thus "cementing" the entire roll
of film together. Attempting to unwind the film in this condition will
only result in torn film. Even if the film did not "cement" together,
standing in water or extreme moisture for any period of time will "lift"
the emulsion from the base of the film. This is also true of silver
film inserted in jackets or inserted/mounted on aperture cards. If it
is reels of diazo film, then the "cementing" may not occur, but you may
still have some sticky film in spots, depending on how wet it got and
how warm the room was after the flood.
If it is silver microfiche that is stacked or filed together with no
enclosures, then you will have the same result only in "clumps" of
"cemented" fiche. Again, even if the fiche did not "cement" together,
standing in water or extreme moisture for any period of time will "lift"
the emulsion from the base. If individual silver fiche were enclosed in
an envelope, then you may only have emulsion loss, and not sticking
together. If the fiche is diazo, there may not be as much sticking
together and you may be able to salvage some of fiche, again depending
on how wet it got and how warm the room was after the flood.

Good Afternoon,
Several months ago we had a flood in the Records Center which has
damaged some microfilm. Problem being this was just discovered and the
film has since dried. Most information I have read states wet microfilm
must be sealed in a plastic bag while still wet and kept in cool
temperature until restored. Wet microfilm is to be transported to the
recovery lab within 48 hours. Has anyone had experience with a similar
situation? Just wondering if it is too late to recovery these records.
Can anyone recommend a good disaster recovery vendor?
Thank you in advance.
