What is a fire protection measure that should be taken for file storage?

Utilizing fire-resistant cabinets is a critical fire protection measure for file storage because these cabinets are specifically designed to withstand high temperatures and prevent the spread of fire to the contents inside. This feature significantly reduces the risk of data loss in the event of a fire incident, thereby safeguarding important documents. Fire-resistant cabinets are constructed with materials that provide insulation and minimize heat transfer, allowing them to offer protection for a specific period, even during a fire outbreak.

The other options are less effective or outright detrimental to fire safety. For instance, using flammable materials or keeping files in regular cardboard boxes can increase the fire load and contribute to a faster ignition and spread of fire. Storing files in a damp area, while it may seem beneficial for preventing certain types of damage, does not address the critical risk of fire and can lead to other issues such as mold or mildew, potentially degrading the documents further. Therefore, the choice of utilizing fire-resistant cabinets stands out as the most appropriate and effective measure for protecting stored files against fire damage.
