Fire rating –when considering a safes ability to withstand a fire it is important to select one which is fire rates, not just fire resistant. By being doing this you can be assured the design has been specifically tested in terms of maximum temperature and duration. The average house fire burns at approximately 1100 degrees for 20-30 minutes. When selecting a safe these two numbers should be considered a minimum level of protection. Most rated safe will have been tested by the Underwriter’s Laboratory (UL), although a number of third parties also conduct similar testing.

Interior temperature- the safe’s ability to withstand fire is but one level of protection, it is also important to consider how well it protects against rises in interior temperatures. Protection of documents, files, passports etc. will require internal temperatures of less than 350 degrees. If you will be looking to protect electronics (CD’s, memory sticks etc.) you will need an internal temperature of no more than 125 degrees.

Waterproof- If you do fall victim to a fire chances the fire department will respond. However, once the fire department arrives and attempts to put the fire out you will face an additional threat – the very water they use to safe your home. Having a safe which is both fire and water resistant will provide a higher level of protection from both threats. The seals and tight fitting doors necessary to achieve waterproofing also provide a higher level of temperature protection as well as protection against smoke damage.
