Things To Know About Fireproof Locking File Cabinets

On the market, there are many different types of file cabinets that are fireproof and lockable. To pick the best one for your needs, keep reading those guidelines and you’ll make the right decision.

UL 1-hour Certificate – Many file cabinets on the list above have this certificate. The fireproof file cabinets are tested and rated by UL. They come with an ETL mark. There are tests at different temperatures and duration marks. Many office file cabinets are rated to last 30 minutes at 1550 °F.

Waterproof Item – The UL doesn’t test how waterproof file cabinets are. If your file cabinet is caught in fire, the firemen will put it out with water. So, if the file cabinet isn’t waterproof, your documents and valuables will be destroyed. So check that before purchase.

Security System – Of course, these file cabinets aren’t burglarproof, but you should definitely invest in a good locking mechanism. You can choose between the physical key and an electronic keypad. You need to protect your documents from people, too.

Build Quality – This is a very important feature, so read the description of the fireproof locking file cabinet carefully. A well-built file cabinet will keep your documents and other valuables safe. The file cabinets should be tested and meet some safety and quality standards.

Letter Vs Legal Files – What kind of valuables do you need to store? Small things like passports, jewelry, cash or similar things fit in any file cabinet. But if you need to store documents, check out if the file cabinet is suitable for letter or legal-size files, or both of them.
