The fireproof cabinets are equipped with fire protection systems to isolate the products stored inside. The level of protection is called by the acronym FR (Fire Resistance) followed by a digit indicating the number of minutes of protection.
This type of cabinets have a double objective:
- Isolate the inside of the cabinet by closing the doors and the ventilation ducts tightly, protecting the products stored inside the cabinet.
- In the case of hazardous products, the level of protection (FR) indicates to the firemen the time margin they have before the products stored inside the cabinets are ignited or exploded.
