Card filing cabinets designed with appropriate insulation to provide resistance against fire. Some cabinets include separate insulation for each drawer, making them fireproof individually. These cabinets are available in several classes according to the protection that they offer against external temperature for a predetermined time (e.g., 927 degrees Celsius/1,700 degrees Farenheit or 1,093 degrees Celsius/2,000 degrees Farenheit for one, two, three, or four hours), keeping the internal temperature at an appropriate value to preserve paper documents (typically below 176 degrees Celsius/350 degrees Farenheit). These cabinets frequently offer additional protection against dropping up to a maximum height (e.g., 9.1 m/30 feet) and/or include sealed gaskets to protect against water penetration. Fire safety card filing cabinets are available in many different configurations and sizes.
