General Overview of all UL ratings
The Underwriters Laboratories (UL) is the trusted source across the globe for product compliance. A product with an Underwriters Laboratories mark is said to be "UL Listed.” and will bear a metal label that states the appropriate UL fire rating and testing standard. All FireKing files will have a metal label attached to the top drawer. Safes bear these labels on the inside of the door and often on the outside bottom edge.

Installing a safe or file without a UL, ETL, Omega Point or Western Fire Center is often considered to be a waste of time and money. In some cases it can also insurance requirements or federal government compliance regulations including HIPAA, Sarbanes-Oxley (SOX) and other PCI or PHI standards.

UL Fire Ratings
As with all fireproof safes and fire files, a UL listing will give you specific information on the standard of protection the fireproof box or container provides its contents (paper or LTO Tapes, DLT, CD's DVD's or hard drives ) when exposed to fire. Every file, hard drive or safe is subject to various test conditions that will expose all six sides to a raging fire (simulating a real world fire disaster). This is accomplished by putting the file cabinet or safe in a large furnace that heats all exposed surfaces to the temperature conditions specified in the test standard.

Underwriters Laboratories use several listings to evaluate records protection equipment safes, storage and file cabinets:

1. Class 350-rated files and safes protect paper documents (wills, deeds, titles, etc)
2. Class 150-rated files and media safes protect magnetic tapes and photographic film
3. Class 125-rated files and data safes protect flexible computer disks, tapes, DVD’s, CD’s and hard drives from heat and humidity

Fire disasters often include a structural collapse or building destruction. All FireKing files and most safes have a UL impact rating standard, one more reason FireKing is the best records protection you can buy. The impact rated file or safe is able to withstand a fall from up to three (3) stories or 30 feet. The actual UL test to get the Impact rating means that the safe or filing cabinet it is heated to 1,550º F in a fire testing furnace, it is then attached to a crane and lifted three stories in the air and dropped onto a pile of concrete rubble and bricks, then put back in the furnace and reheated. To to meet the listing requirement, temperatures inside can't have risen above 350 degrees Fahrenheit (well below the charring and burning temperature of paper) and sample testing papers that are left inside the safe or file cabinet mus be readable.
