How are safes Rated?
Many fire–protection, anti–theft, and media safes come with a rating from Underwriters Laboratories, an independent, not–for–profit product–safety testing and certification organization. Underwriters Laboratories rate anti–theft safes based on how long it would take someone to burglarize them. For fire–protection and media safes, the company says “the hourly rating signifies the amount of time the device can withstand a standardized fire of controlled extent and severity.” Staples offers fire–protection safes rated for ½ hour, one hour, and two hours of protection.
