Most likely, it means that the film has an Estar (or whatever Kodak called it back then) base instead of a celluloid base. The safety film ignited at a higher temperature than the older celluloid stuff. Thus - safety film. As far as EI goes, you'll just have to wait for someone more knowledgeable than me to reply.
Nope. Cellulose acetate was the "Safety Film". It replaced cellulose nitrate, the stuff that tended to spontaneously combust. Estar (same as Mylar) was a much later development.
