Where and Why Waterproof Safes Are Needed

A waterproof gun safe protects your valuables in the event of a flood or similar situation. You should probably use such a safe anywhere you store valuable items, whether in your home, office, or even your car. Several situations where waterproof gun safes are of utter importance include:

Natural Calamities

Hurricanes have become a very common natural phenomenon in recent years and end up causing a lot of damage due to water logging and floods. If you live in an area prone to such events, using a waterproof gun safe is your best bet to protect your valuables. It can house firearms, documents, jewelry, or even precious heirlooms.

What most people don’t realize is that most fireproof safes are not waterproof. In the event of a fire, the first thing anybody will do is to spill water over your safe, which will seep into your safe through the dehumidifier/power cable hole.

Damp Environment

If you live in soggy or damp kind of environment, there are chances that moisture will build inside your safe and will damage your weapons. To counter that you either have to use a dehumidifier or a small light bulb. However, a waterproof safe eliminates the need for both and seals your safe against moisture

Considerable Factors to Look For in a Waterproof Gun Safe

Waterproofing is not the only factor to consider when buying a waterproof gun safe. A good safe must provide overall protection to its contents and this is where other important factors come into play. The most important of these include:


A gun safe must have adequate space to fit all the firearms and valuables you desire to store in it. If you are planning to increase your collection of firearms in the near future, or foresee the possibility of storing other extra items in the safe, you must go for a large waterproof gun safe.


This factor is directly influenced by the thickness and the material of the gun safe. The most common material used to manufacture these safes is steel, and its thickness is measured in terms of gauge. The smaller the gauge, the thicker the steel. For example, a 12-gauge steel safe means it is 2.732mm thick and 0 gauge means it is 7.9375mm thick. Hence, a safe made from lower gauge steel is more durable and sturdy.

Fire Safety

Apart from being waterproof, a good safe must essentially be fireproof. The level of fire resistance is measured in terms of UL fire rating. The rating is basically categorized into three classes, namely Class 350 rated (protects paper products), class 150 (protects magnetic tapes), and Class 125 (protects flexible computer disks).

Furthermore, safes are typically one or two-hour fire rated, which explains the amount of time for which a safe can resist a certain amount of temperature without the inside getting too hot.


Waterproofing in a gun safe is not a very common feature and you will have to spend some extra money for such safes. However, it doesn’t have to burn a hole through your wallet. Additionally, the size of the safe and the value (monetary and emotional) of the contents should guide your intent to spend more or less.

Alternate Methods of Waterproofing Guns/Ammo

If you want to take extra steps to keep your items dry, you can easily do so with the following.

A very cheap and effective method of waterproofing guns/ammo/documents or other valuables is to store them in ziplock bags or airtight Tupperware containers and then store them in any safe. You can also use double zip locks for very important documents or sensitive items.

Another very safe approach is to store a waterproof safe with your contents inside another larger gun safe. This way, your valuables will stay protected from water and will be more secure inside two gun safes.

Another very intelligent method is to store a desiccant, like silica gel, in your gun safe or inside the aforementioned things (ziplock bag/container/small safe), so you can ward off even the most minor chances of dampening.


A waterproof gun safe offers effective and reliable protection against natural calamities and other events which might affect your guns and valuables. Apart from being waterproof, such a safe must be durable, fire-resistant, have ample storage space, and be affordable. A waterproof and fireproof gun safe offers overall protection against every possible threat.
