This document discusses safety ratings for safes. It explains that safes are rated based on their resistance to burglary tools like cutting torches, explosives, and hand/power tools. The most reliable rating system is performance ratings from independent labs like UL, which assigns codes designating the tools and length of time a safe can resist attack. Higher rated safes protect against more tools for longer periods. Fire safes also receive ratings from labs like UL based on the temperature and humidity they maintain for paper, electronics, or both. Proper selection depends on the contents being stored.
