(Or maybe once every five years, depending on how productive they are :-) . ) That's a UL Class 350 1-hour rating. My understanding is that photographic materials aren't safe at that temperature and humidity level (350 degrees F, 85% humidity), and that the Class 125 or class 150 is necessary (so-called "media" safes, developed for floppies and optical disks); but I can't find any authoritative source online saying what they think is safe for photo materials. Do you have a good source for what experts consider survivable? (My position seems to be commonly repeated by random posters online, but I can't find anywhere that I take seriously that either confirms or denies it.) -- David Dyer-Bennet, dd-b@xxxxxxxx; http://dd-b.net/ Snapshots: http://dd-b.net/dd-b/SnapshotAlbum/data/ Photos: http://dd-b.net/photography/gallery/ Dragaera: http://dragaera.info Nikon DSLR photo list: http://d4scussion.com
