Do I need a Tornado Shelter?

Will your family will be safe in the event of a severe storm or tornado? If you are asking yourself this question purchasing a Tornado shelter for your home can offer peace of mind. Having a safe place to go in an emergency is an investment into the safety of your family. When making this decision there are many things to consider. There are many different types of Tornado shelters available and navigating these differences is the first step to making sure your investment goes as far as possible.

Tornado Shelter Safety

When thinking about buying a Tornado shelter the cost, size, material and installation process are usually the initial considerations. There are many sizes and shapes of shelters from very small to those able to protect entire communities. The size of a Tornado shelter needed is largely determined by the size of the family using it. Though most storms will not require long stays in a shelter, being sure there is comfortable seating and ample room for some emergency supplies is important.

Underground is Safest

There is also the consideration of if a below ground shelter or above ground shelter is right for your family. Being under the ground is the safest place to be in a tornado and an in-ground shelter designed to protect you in these storms is safer than any basement. Any person who is physically able to get into an underground unit is safest in the ground. For those who are not physically able to get into an underground Tornado shelter there are many above ground options available. Though above grounds units have been known to perform well in tornados, being above ground simply is not as safe as being below the ground.

Shelter Materials Make a difference

Understanding the material a tornado shelter is manufactured from is the most important element to consider how long your shelter will last. This is especially true for in-ground tornado shelters. The material a shelter is made from dramatically influences maintenance and lifespan of this type of product. Some materials deteriorate much faster than others, especially if they are buried in the ground. Different shelters need different degrees of maintenance which can include painting, cleaning, patching cracks or deterioration, oiling hinges, inspecting latches and scraping rust.

Shelter Door = Safety and Security

The most important part of any Tornado shelter is the door. For most underground tornado shelters the door is the only part exposed to the tornado. Because the door being safe is such an essential part of being protected, FEMA requires shelter doors to be tested to withstand an F5 tornado. Manufacturers of shelter doors that have been tested to withstand an F5 tornado should be able to verify that they have exceeded FEMA 320 or FEMA 361 requirements by documentation of the test.
