Are there fire-rated lateral file cabinets?

Fire-rated lateral cabinets are tested under UL 72 / UL Class 350 and are available in 1-, 2-, and 4-hour ratings. They maintain internal temperature below 350°F. A 4-drawer fire-rated unit may weigh 600–900 lbs and costs significantly more than standard units.
