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 other things. 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.
