When choosing a safe, another important factor in choosing the right safe is the fire rating. Fire ratings indicate the degree of protection the safe has in the event of a fire. The purpose of having a fire rated safe is to protect documents and its other contents. Fire rated safes come in many different ranges of fire ratings including (and not limited to) 30 minutes, 45 minutes, 1 hour and 2 hours. Safes can be rated by different testing authorities using multiple different methods.
