Room-sized fireproof vaults

For larger volumes of heat-sensitive materials, a modular room-sized vault is much more economical than purchasing and storing many fire rated safes. Typically these room-sized vaults are utilized by corporations, government agencies and off-site storage service firms. Fireproof vaults are rated up to Class 125-4 Hour for large data storage applications. These vaults utilize ceramic fiber, a high temperature industrial insulating material, as the core of their modular panel system. All components of the vault, not just the walls and roof panels, must be Class 125 rated to achieve that overall rating for the vault. This includes the door assembly (a double door is needed since there is no single Class 125 vault door available), cable penetrations, coolant line penetrations (for split HVAC systems), and air duct penetrations.

There are also Class 150 applications (such as microfilm) and Class 350 vaults for protecting valuable paper documents. Like the data-rated (Class 125) structures, these vault systems employ ceramic fiber insulation and components rated to meet or exceed the required level of protection.

In recent years room-sized Class 125 vaults have been installed to protect entire data centers. As data storage technologies migrate from tape-based storage methods to hard drives, this trend is likely to continue.

UL certification for safes

Underwriters Laboratories (UL) testing certifications for safes are known to be the some of the most rigorous and most respected in the world. They are only matched by B.T.U/VDMA certifications (Germany). J.I.S. (Japan) and CSTB (France) preheat the oven with the safe inside until the temperature reaches the desired setting (as opposed to a sustained temperature of the rating), then the safe is cooled artificially (as opposed to naturally). Also, J.I.S. and CSTB only drop their safes from 13–15 feet (as opposed to 30). Rarely are safes dropped 15 feet (4.6 m) or more and they are usually artificially cooled by the fire department. UL also runs an indirect explosion test on all safes. Additionally UL-768 certifies the combination lock against tampering. UL-140 certifies a relocking mechanism that will permanently lock the safe bolts, in case an electronic lock fails or a UL-768 rated lock is compromised.

Class 125

The safe sustains an internal atmosphere of 125 °F (52 °C) and 80% humidity. This class was introduced with the emergence of floppy disks. The safes are tested with only non-paper media, but are clearly sufficient to hold paper. New, more durable computer media, such as data on compact disks crystallize at 350 °F (177 °C),[4] which make this type of safe overly-sufficient to store these media.

However, Underwriters Laboratories have not tested whether data on Blu-ray disks, DVDs or CDs are altered during testing. They have just tested floppy disks, which are not a common storage medium these days.

An added benefit of this safe is that it is waterproof due to a gasket on the door and the label will state this. These class ratings are used in conjunction with hour ratings such as: ½, 1, 2, 3, or 4.

Class 150

The safe sustains an internal atmosphere less than 150 °F (66 °C) and 85% humidity. This class was introduced with the emergence of computer data tapes or magnetic reel-to-reel tapes. UL tests this with paper and non-paper articles. This safe is also sufficient in storing some optical media, such as compact disks. Cases can be purchased that will meet Class 125, if they are placed inside a Class 150 safe. Some may be waterproof due to a gasket on the door and the label will state this. These class ratings are used in conjunction with hour ratings such as: ½, 1, 2, 3, or 4.

Class 350

The safe sustains an internal atmosphere of less than 350 °F (177 °C) and 85% humidity. This is the most basic of U.L. tests and specifically tests for the storage of paper. The ignition point of paper is 450 °F (232 °C), so this safe is sufficient for storage of paper. Cases can be purchased that will meet Class 125, if they are placed inside a Class 350 safe. These class ratings are used in conjunction with hour ratings such as: ½, 1, 2, 3, or 4.

Class TL-15

This is a combination locked safe that offers limited protection against combinations of common mechanical and electrical tools. The safe will resist abuse for 15 minutes from tools such as hand tools, picking tools, mechanical or electric tools, grinding points, carbide drills and devices that apply pressure.

Class TL-30

This is a combination locked safe that offers moderate protection against combinations of mechanical and electrical tools. The safe will resist abuse for 30 minutes from tools such as hand tools, picking tools, mechanical or electrical tools, grinding points, carbide drills, devices that apply pressure, cutting wheels and power saws.

Class TL-40

This is a combination locked safe that offers moderate protection against combinations of mechanical and electrical tools. The safe will resist abuse for 40 minutes from tools such as hand tools, picking tools, mechanical or electrical tools, grinding points, carbide drills, devices that apply pressure, cutting wheels and power saws.

Class TRTL-30

This is a combination locked safe that offers high protection against combinations of mechanical, electrical, and cutting tools. The safe will resist abuse for 30 minutes from tools such as hand tools, picking tools, mechanical or electrical tools, grinding points, carbide drills, devices that apply pressure, cutting wheels, power saws, impact tools and, in addition, can withstand an oxy-fuel welding and cutting torch (tested gas limited to 1,000 cubic feet (28 m3) combined total oxygen and fuel gas.)

Class TRTL-60

This class will withstand the same assaults as Class TRTL-30 for 60 minutes.

Class TXTL-60

This class meets all the requirements for Class TRTL-60 and, in addition, can withstand high explosives such as nitroglycerin or equivalent to not more than 4 ounces (110 g) of nitroglycerin in one charge (entire test must not use more explosive than that equivalent to 8 ounces (230 g) of nitroglycerin).

European Safe Standards

Depending on the usage CEN has published different European Standards for safes. Testing and certification according to these standards should be done by an accredited body.

EN 1143-1 is the main testing standard for safes, ATM safes, strongroom doors and strongrooms. For safes it features eleven resistance grades (0, I, II to X). From one grade to the next the security rises by approximately 50%. Testing is based on a free choice of attack tools and methods. Testing requires partial access (hand hole) and complete access attempts, on all sides of the product. The security is calculated by using ratings of tools and the attack time. The result is expressed in resistance units (RU).

EN 14450 is a testing standard for secure safe cabinets. The standard covers products meant for purposes where the security resistance required is less than that of EN 1143-1.

For fire resistant safes the EN 1047-1 (fire resistance standard similar to the fire resistance safe standard of UL) and EN 15659 (for light fire storage units) were published.
