Unless I'm mistaken (I've been mistaken before!), "safety film" refers
to the flammability of the film base, and has nothing to do with a safe
light for processing.
From Google/Wiki: "Cellulose acetate film, or safety film, is used in
photography as a base material for photographic emulsions. It was
introduced in the early 20th century by film manufacturers and intended
as a safe film base replacement for unstable and highly flammable
nitrate film."

Had that happen once too. In that case though I knew what was on it, and although there might have been some interesting flower pictures lost, that would not be nearly as bad a losing one that had your great grandmother on it when she was young.
I'm wondering if a film scanner that feeds from the sprockets could get the film flat enough. My flat bed with its holder I am sure wouldn't. Got two labs that might be able to do it. Anyone recognize 3LIM or 31IM? It is a safety film, which might mean this film could have been processed under a safe light. My search has turned up nothing. Just knowing that might be an important piece of information.

Doing a project with very old family photos. I have a strip of
35mm negative that on it says safety ILM 3 I think it is, but
that isn't the biggest problem. It was over the years creased
like paper that had been folded. Some of the folds are through
the middle of the image. Any way to flatten.
I have no idea what is one them. Judging from the prints found
with it, I would wager a best guess of about 50 years. They
don't appear to be scratched up.
First idea is to contact print them with glass on top to see what
I have. I could probably copy them from a contact print, but
would rather have the wet print if possible. Would leaving them
sandwiched between two plates of glass with some weight on top do
any good. Though about soaking them, but thought better of that
pretty quickly. Might or might not help. Ideas and thanks everyone
I’d second your instinct that soaking might not be ideal. I have
had some poor experiences where old emulsion just sloughed off the
substrate when trying to clean old negatives with water.
