Do fireproof cabinets also protect against water from fire sprinklers?

UL fire testing for filing cabinets includes a water hose test (simulating sprinkler and firefighting water) following the fire exposure. Cabinets that pass this test are rated for both fire and water intrusion. Check whether the specific cabinet you're considering carries both fire and water certifications, as some models are fire-only rated. The drawer seals that prevent flame entry also provide some water resistance. OfficeFurniture2go.com can confirm water resistance ratings — call 1-800-460-0858.
