Most home safes fulfill one of two important functions. Either the safe protects against theft, or it shields contents from fire damage. It's a serious, but common, mistake to assume home safes with a burglar-proof rating also protect against fire, or that a fire-proof safe will foil a determined burglar. If you need protection against both fire and theft, you need a composite safe specifically designed to meet both threats. To ensure a home safe meets both demands, it must undergo rigorous testing.
