Safes are typically used to store important documents, cash or other valuable items which aren’t too large in size. When storing such items in a safe, you typically expect that the safe will be able to withstand any accidental hazards. This includes fire as well as water.
Storing your valuables in a water-resistant safe is important. A water-resistant safe is well sealed so that even if it is submerged into the water, the contents of the safe will not gather any damage. Most water-resistant safes come with the ability to withstand water for up to 24 hours – you can look at this example.
Even if you do not directly anticipate the possibility of water submerging your safe, a water-resistant safe is still a good idea. That is because water-resistant safes are typically well-sealed and moisture-proof. So regardless of what weather conditions are on the outside, the contents inside the safe will remain dry and well protected.
An important thing to note about water-resistant safes is that they are not water-proof in all circumstances. For instance, many notable water-resistant safes are able to withstand pressure when submerged in water of up to 8 inches depth. When submerged in water deeper than this, the pressure on the safe walls grows greater. As a result, the safe and its contents may get damaged.
So realistically, even if you have a water-resistant safe, you should consider it as secure storage only in scenarios of accidental submerging. And even then, you should take care to rescue the safe from the water within 24 hours. After 24 hours, a typical water-resistant safe will lost its seals and water will enter it.
