What are the fire resistance ratings for fire-rated lateral file cabinets?

Fire-rated lateral file cabinets are independently tested and typically carry a 1-hour rating, meaning they protect paper documents from fire damage for at least 60 minutes at external fire temperatures up to 1,700°F. Some models achieve a 2-hour rating for higher-value document protection. Interior temperatures must stay below 350°F (the point at which paper chars) during the test period. Look for UL 72 Class 350 certification on any fire-rated cabinet you're evaluating. FindOfficeFurniture.com can help identify fire-rated lateral file options — call 888-719-4960 for the best deals.
