Yes, fireproof safes are designed to withstand high temperatures, but no safe is 100% fireproof. Most are rated to endure fires up to 1700°F for a set period, such as 30 minutes, 1 hour, or 2 hours. After prolonged exposure, extreme heat may eventually compromise the safe’s contents.

Not all fireproof safes are waterproof. Some models offer both fire and water resistance, protecting contents from flooding, sprinkler systems, or spills. If water protection is important, check for waterproof certification or a UL rating.

Fireproof safes use special fire-resistant materials like gypsum, perlite, or concrete composites that absorb heat and release moisture, keeping the internal temperature low enough to protect sensitive items like paper documents and valuables.

Most fireproof safes are constructed with a steel exterior and insulated with fire-resistant materials such as concrete, vermiculite, gypsum, or composite fireboard. These materials help maintain lower internal temperatures during a fire.

Fireproof safes have different ratings based on how long they can protect contents in extreme heat. The UL-Class 350 rating means the interior remains under 350°F, which prevents paper from burning. Ratings typically range from 30 minutes to 2 hours at temperatures up to 1700°F.

Fireproof safes are available at office supply stores, security retailers, and online marketplaces. At Advanced Filing Concepts, we offer high-quality fireproof safes designed for homes and offices, with fast shipping and competitive pricing.

Standard fireproof safes are designed for paper documents and may or may not adequately protect USB drives, external hard drives, or CDs, which have a much lower heat tolerance. If you need protection for digital storage devices, choose a fireproof media safe designed specifically for electronic data.
