The "Fireproof Bag" - Burning Questions

Our most frequently asked questions.

Is the bag really fireproof? Is it guaranteed to protect against any fire?

The bag is fire-resistant, which means that it will provide adequate protection for most fires. Beware of any manufacturers who claim that their bag is "fireproof". There is no such thing. Think about it. Not much will survive an intense multi-hour fire that burns a dwelling to the ground. Thankfully, that is a rare occurrence. The Flame Fortress® bag will protect against fire that is contained within a reasonable amount of time. It is an inexpensive and convenient alternative to owning a large, heavy "fireproof" safe, which still might not be 100% fireproof. Flame Fortress Inc. can not be liable for any losses when using the Flame Fortress® bag. Please read our Terms of Use for more details.

Has the bag been lab tested for fire resistance?

Absolutely! The bag has been tested by an independent lab to two different North American fire standards. All tests passed. More specifically, the material meets the performance criteria of the Standards Council of Canada CAN/CGSB-155.1-2001 Standard for protection against heat and flame, and meets the flame propagation requirements of the National Fire Protection Association NFPA 701-2015 Standard.

How many sheets of paper can the bag hold?

A lot! It's a huge 12 inches x 16 inches (30.5 cm x 40.6 cm) in size. The bag lies flat to start, so it doesn't really have much depth, but the sides expand as items are placed into the bag. Let's put it this way, it easily fits an entire package of 500 sheets of letter sized (8 1/2 inches x 11 inches) paper. Big Flame Fortress® Fire-Resistant Bag

Customers Love Our Fire Proof Bag

Read what our customers have to say about the Flame Fortress® fire-resistant document bag.

This is a very high quality product. I have no doubt that it will help to protect my childhood photos from fire. And it doesn't cut my hands like another fiberglass bag I purchased.

Vivian Oder

Toronto, Ontario

I use this to store my Will, deed to my property, and all of our family passports. I actually tried to light it on fire using a propane torch, and it did not burn.

Arthur Vardjas

Minneapolis, Minnesota

I hope I never need to find out how well this bag performs in a fire, but it is a very well-built, heavy-duty bag. I bought two and gave one to my grandmother --- she loved it!

Dave Hunter

Vancouver, B.C.

I was looking for a fireproof safe but found this bag instead. This is a much better solution for me. Much cheaper, big enough to store legal documents without folding them up, portable, and I can store it out of sight in a drawer. Highly recommended.
