Does a fireproof cabinet also protect against water damage?

Standard UL-rated fireproof cabinets are not waterproof — the insulating core actually produces steam during a fire, and that steam can damage unprotected media inside the cabinet. UL testing covers structural integrity and heat resistance, not water exclusion. If you need protection from both fire and water — including sprinkler systems and flood events — you need a fire-and-water-rated unit with a separate waterproof certification.
