What is fire resistance?

A fire resistant safe is constructed in order to protect its contents against fire for a specified period of time. Not all information can be stored in the same way, there is a big difference between paper and data media. Fire resistance is always expressed in time (30-60-120 minutes). These times indicate how long a safe can stay in the fire before it reaches a critical temperature. Another important factor is whether the safe can be used for paper or data media.
 
Storing paper
Paper will show spontaneous chemical reactions like colouring and curling from a temperature of 176°C. Fire resistant cupboards and document safes have been designed to prevent this.
 
Storing image media
Image media, such as (micro)film are already damaged around 95°C, thus the maximum temperature in the safe should not exceed 75°C. It is advisable to store image media in a fire resistant data safe.
 
Storing digital media
A fire resistant data safe protects digital media such as CD/DVDs and data tapes against temperature higher than 52°C. Exposure to temperatures higher than 52°C can damage data media and data can be lost. A humidity exceeding 85% can also be fatal for data media.
 
Fire resistance norms
In Europe various fire resistant norms are used. Independent testing institutes expose safes for a period of 30, 60 or 120 minutes to a temperature of 1090°C. During the test the safe is dropped 9.15 meters to prove that the fire resistance is intact should the safe fall through a storey during a real fire.
 
During the test and after a natural cooling period of 12 hours, the temperature inside the safe should not be higher than the previously mentioned temperatures.
The most important and common test institutes for
fire resistance are:
  • UL: American test institute
  • VDMA: German test institute
Safes tested at testing institutes accredited by the ECB-S offer extra security. These safes are certified by the ECB-S which guarantees extra high quality and levels of reliability!
