What is the difference between a 1-hour and 2-hour fire rating?

A 1-hour UL-rated fireproof cabinet is tested to maintain its interior below 350°F for at least 60 minutes during a fire. A 2-hour rated cabinet provides double the protection duration. Industry guidance recommends 1-hour protection for standard commercial environments where fire response times are typically under 10 minutes. Records management facilities, data vaults, and organizations storing irreplaceable documents should specify 2-hour or higher ratings. At OfficeFurniture2go.com, we carry both ratings — call 1-800-460-0858.
