Fire-resistant safe

Fires occur regularly in Belgium and represent a real risk for residential buildings, offices and businesses. Each year, fire services respond to thousands of fire incidents, showing that fire is unfortunately not an exceptional event.

According to fire prevention organisations such as ANPI, fires remain a frequent cause of significant damage to buildings and their contents.

Although much information is now stored digitally, important documents and assets are often still kept in physical form. This includes contracts, property deeds, notarial documents, wills, backups, keys and cash, but also items whose original value is difficult to replace, such as photographs, archives, rare books or works of art.

In the event of a fire, these documents and objects can be lost or permanently damaged within a short time. Temperatures can exceed 800 °C, making adequate protection essential.

To protect documents and valuable contents against these risks, a fire-resistant safe is commonly used.

A fire-resistant safe is designed to keep the internal temperature below a critical threshold during a fire. For paper documents, this limit is around 170 to 180 °C, while digital media such as hard drives, tapes and USB devices can be damaged at temperatures from approximately 55 °C. For this reason, a clear distinction is made between protection for paper and protection for data media.

Fire-resistant safes are tested according to standardized fire tests that simulate a severe fire using a predefined temperature curve. During these tests, temperatures rise rapidly to over 500 °C within minutes and can exceed 1,000 °C over time. The safe must ensure that the internal temperature remains within the permitted limits.

After testing, fire-resistant safes are certified by independent certification bodies, such as ECB-S. Fire resistance is expressed as a time rating, typically 30, 60 or 120 minutes, depending on the applied standard and the type of content to be protected (paper or digital media).

More information about standards and test methods can be found on
fire resistance classes and test methods.

The choice of a fire-resistant safe is not only determined by the contents to be protected, but also by the environment in which the safe is installed. Local conditions can have a significant impact on the development and intensity of a fire.

Certain locations present a higher fire risk or contain larger amounts of combustible materials. In environments such as attics with wooden structures, fuel storage areas, timber warehouses or parking garages with vehicles, a fire can develop more rapidly and last longer. Based on these factors, the required fire resistance class or standard can be determined to ensure adequate protection.

The position of the safe within the building is also important. A safe installed under a roof structure or in a poorly compartmentalised space may be exposed to higher temperatures than a safe placed in a more protected environment.

In addition to fire itself, secondary risks should also be considered. During firefighting operations, large amounts of water may be used, which can lead to partial flooding of the area where the safe is located.

Depending on these risks, additional measures may be appropriate, such as fire compartmentation, fire-resistant walls and doors, or automatic fire suppression systems. These measures can help limit the impact of a fire and improve the protection of the safe’s contents.

At Atelier Boonen, a fire-resistant safe is not considered a standard product, but a solution that must be adapted to the application and its environment. The selection depends not only on the required fire resistance, but also on the type of contents to be protected (paper or digital media), the installation location and the possible need for burglary protection.

As a Belgian family business, Atelier Boonen supports both private and professional clients in selecting fire-resistant safes in Belgium, based on a concrete assessment of risks and requirements. The advice is independent and not limited to a single brand or product range.

Atelier Boonen also provides the delivery, installation and anchoring of fire-resistant safes, carried out by its own team. This ensures correct installation and consistent follow-up.

By operating exclusively in Belgium, Atelier Boonen guarantees a reliable and structured service, from initial advice to installation and aftercare.
