Best Small Fire Proof Safe Worth Considering

Last updated: October 1, 2023


In the event of a break-in or fire, which occurs every 23 to 93 seconds in the U.S., a fireproof safe is the best way to protect your valuables. Finding the right fire-rated safe is critical whether you want to store a large number of items in a large floor-mounted safe or protect important documents and valuables, such as birth certificates, in a small portable safe.

Most fireproof models come with keys, electronic combination locks, or both. You can also select from a variety of sizes, thicknesses, and shelf configurations. Based on our extensive research, we have compiled a list of the best fire proof small safes, as well as a few reasons why we chose them. Here’s what you need to know. 

What To Consider When Looking For A Fireproof Safe

There are numerous options available in the market for fireproof safes nowadays. Beginners and first-time homeowners could easily get confused about what safe to buy. Here are a few things you should keep in mind when choosing a fireproof safe. 

Fire Resistance

A fireproof safe is expected to withstand high heat and flames, but not all safes are created equal. Some have low fireproof ratings and can only withstand extreme heat for 30 minutes before sustaining damage. Many models are rated for one hour of fire exposure, while the most robust safes are rated for two hours. Some fireproof safes are also waterproof or drop-tested.

A fireproof safe that could withstand 1,550 °F to 1,700 °F for 60 minutes offers good enough protection for your valuables.  


Fireproof safes are available in a variety of weights, which greatly affects how portable they are. Some larger safes can weigh 45 kilograms. or more, which can be a deterrent to thieves but not so much if you want to transport your safe. Choosing a lighter fireproof safe will be more convenient if you need one to carry around with you. There are many portable models that weigh between 4 and 7 kilograms. 

Lock Mechanism

Choose a strong locking mechanism for your fireproof safe to keep its contents safe. Traditional lock-and-key closures are available, but there is a risk of misplacing the key. Other fireproof safes include a keypad where you can enter a passcode to unlock the safe. However, some safes employ a combination lock, which eliminates the risk of lock-picking associated with a keyhole. Choosing the appropriate lock mechanism for your fireproof safe is entirely up to your preference, but we recommend going for a combination lock for improved protection.
