Fire Protection for Paper Documents

Each Phoenix fire-resistant model is independently tested to European or American standards for fire protection and carries certification labels from the testing agency that identify the product’s fire protection level. Products that provide fire protection for paper records are listed with the designation of “Class 350.” Tests for products designed to protect paper records range from 60 to 120 minutes in temperatures ranging from 1700°F to 1859°F. By comparison, a typical fire lasts 20 minutes and reaches 800°F. During the fire test, the internal temperature of the product is monitored to ensure that it does not rise above a level that would endanger the paper documents stored within the product. The designation tag also indicates the length of the fire test as “1 HR, 1 ½ HR, or 2 HR” and is located next to each model number.
