Introduction to Tornado Shelters

America’s Leading Tornado Shelter

Thinking About a Tornado Shelter? Thousands of people every year experience the power of killer storms and tornados. Many of those people do not have a safe place for their family to go during these unpredictable weather events. If you are thinking about purchasing a tornado shelter for your home there are many considerations. Having a safe place to go in an emergency is an investment into the safety of your family. 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.

When thinking about buying a tornado shelter there are many questions to answer. What type, size, material and installation requirements are usually the initial considerations. There are many sizes and shapes of storm shelters. The size of a 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.

There is also the question of whether a below ground shelter or above ground shelter is right for your family. Being in 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 a below ground unit is safest in the ground. For those who are not physically able to get into a shelter there are many above ground options available. Though above ground units have been known to perform well in tornados, being above ground simply is not as safe as being in the ground.

The door of a tornado shelter is also a very important element. For most underground units 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.

The material a shelter is made from dramatically influences maintenance and lifespan of this type of product. Different shelters need different degrees of maintenance which can include painting, cleaning, patching cracks or deterioration, oiling hinges, inspecting latches and scraping rust. Some materials deteriorate much faster than others, and will eventually become unusable. Material lifespan is what makes your shelter last the longest and be of the most value.

But, one of the most important consideration is finding a tornado shelter manufacturer that can be trusted and will be available for their customers. It is essential to research the company making this life saving product for your family. A company that can be trusted will have a history of manufacturing this type of product and be familiar with FEMA guidelines for ensuring safety during these deadly storms.
