How To Choose The Right Fire Safe Box?

Here are a few factors to consider while purchasing a fire safe box.

  • Water rating: Safes must also withhold water like fire. A floatable safe with tight doors provides water resistance to keep the documents and valuables from damage.
  • Storage capacity: Consider a safe with a large storage capacity to save a reasonable number of important documents, cash, and jewelry.
  • Lock system: Most safes have a digital keypad system requiring a three to eight-digit password. A set of emergency keys are also provided for manual opening.
  • Material: Most safes are constructed of steel. Chromium-plated aluminum safes are less fire-resistant. Padded interiors protect the valuables from any overthrows that are common during emergencies.

Frequently Asked Questions

1. Do fireproof safes work?

Yes, they work, but hold several limitations. Any material can burn in a fire if exposed for a long time. Hence, it is better to say that fireproof safes protect your valuables for a limited period. Look at the fire-rating before purchase as it determines the time range your valuables will be kept safe in case of emergencies.

2. What are fireproof safes made of?

The fireproof safes are made of metals with high melting points. Steel is one of the most common materials used. The durable coat finishes on the exteriors add to their resistance factor.

3. Where to put a fireproof safe?

It depends on the size of the safe, layout of the house, and the contents in the safe. You can put them near the routes of exit so that you can quickly grab during house fires. Never place a safe near any flammable objects.

4. What is UL 72?

A UL 72 rating is given to a safe based on the below three factors.

    1. Classification: It determines the products that can be kept safe in this safe box. The three classes are:
      • Class 350: Protects documents and other malleable items
      • Class 150: Protects any item with magnetic tapes
      • Class 125: Only protects low-durable items such as compact or floppy disks
    2. Duration: It determines how long material can withstand fire before its characteristics are compromised. The duration can range from 30 minutes to four hours.
    3. Ratings: This factor is determined after several tests in the laboratory. The safes are tested to varied fire impacts, explosions, and fire endurance. A safe is kept inside a high-temperature oven for long periods, and the interiors are tested with humidity detectors. But as house fires are unpredictable, this factor may not be entirely accurate.

5. How to set a safe combination?

For setting a safe combination for the first time, refer to the manufacturer’s instruction manual. The most common steps of setting up a password are as follows:

1. For safes with combination wheels

      • Identify the keys for setting up the password
      • Keep the door open to prevent any accidental locking
      • Turn the combination wheel by setting on the first digit of your preferred password. Then turn the wheel two times and place it on the second number. Repeat this until your required set of numbers has been attended to. This step differs from safe to safe.

2. For a digital safe

      • Select your preferred combination of passwords. Avoid any common numbers such as birthday and phone numbers
      • Open the door and set the number
      • Press the number zero and wait for a few beeps. This step can vary for different safes.
      • Enter the password again and wait for the beep. Repeat this step after the end of the beep. By repeating the codes, you should see the locking bolts retract and extend.
      • Shut the safe and check if it is locked. You can again enter the password to check its opening mechanism.

6. What happens if I forget a safe combination?

Most safes come with emergency opening options that can be used in case you forget the combination. You can override the lock with keys or even manually. Follow the manufacturer’s protocols to override the safe manually. You can contact the manufacturer and verify your information to administer their overriding protocols. If nothing works, you can always go to a locksmith for help.

A fireproof safe helps keep your documents locked and protected from unprecedented fire accidents. When choosing the right one, consider its durability, ease of use, and portability to make an informed choice. Also, consider an alternative if the safe box requires batteries to function, is not water-resistant, and does not have the required storage capacity and a warranty. Our list of the best fireproof safe boxes includes various sturdy options with different features and advantages that you can analyze to understand your requirements.
