Reading listings: Check the product page for the stated fire class, water test, and bolt-down details. Prefer units with independently verified ratings.
How to Choose the Right Fireproof Safe
- Rating: For paper, look for listings that note UL Class 350 or equivalent testing. Longer time = more protection.
- Capacity: ~0.5–1.2 cu ft for documents; >1.2 cu ft for binders, drives, cameras.
- Water: Prefer ETL or listing-noted water protection; seals matter post-fire.
- Lock: Digital is fast; dial is simple; dual key adds redundancy.
- Bolt-down: Anchor uprights if the listing supports it.
Fire Rating Standards
UL Class 350: Paper protection. Interior kept below 350°F during the rated time/temperature.
Class 150 / 125: For magnetic/digital media. Lower interior temperatures.
ETL: Often verifies water and drop after heat. Read the listing details and the label on the unit.
Marketing claims without a stated test method or lab mean uncertainty. Favor clearly specified tests.
