Why the Inground Safety Shelter?

Every home should have a safe room for families to use in case of emergency. But if you home or business is located in an area known for sever storms and tornadoes, an interior room may not be enough to survive uninjured. This is especially true for manufactured homes and buildings, or any structure without access to a basement or a below ground level. Whether you live in a populated area or a remote location, there are many possible emergencies, disaster situations or local conditions in which you and your family would just feel safer in a protected place that is inaccessbile to tohers and nearly indestructible to the elements.

As you can see from the graphic below, a smaller group of Western-most states are only likely to see Tornadoes up to 130 mph, but the over whelming majority of states could see Tornado wind speed, typically 160 mph or faster. While a large, centralized population could see Tornado wind speeds in the 200-250 mph range!

Many people well tell you from personal experiences, tornadoes can cause true devestation. Tornadoes are well known for home destruction, as well as demolishing some of the strongest structures know to man. They throw trees and cars, down dangerous power lines and pick nearly anything up that crosses its path. As most safety experts will tell you, in a time of heavy storms and tornadoes, below ground in a safety shelter or a safe room is the safest place to be.

The Door to Safety

The door is of the I.S.S. is a crucial part of it's protetion. It's design has been FEMA tested and surpassed the rigorous requirements. All the testing in the world is worthless if it is not easily accessable. In an emergency when seconds count, the security door on the I.S.S. is extremely easy to use. The gas-assisted shock makes opening and closing the security door simple, something that nearly anyone can do. Once you are in the shelter (3) locks tightly secure the door. When the emergency situation is over and it is safe to get out simply release the locks and easily push the door open.... the gas assisted shock does the rest.

Tornadoes are measured in the "Fujita Scale" (or F-Scale). Commonly referred to as an "F1, F2, F3, etc.", the scale rates Tornadoes on intensity, based on the damage that is inflicted upon human-built structures and vegetation. The official scale is determined by meteorologists and engineers after a ground and/or aerial damage survey; contingent upon the circumstances, ground swirl patterns (cycloidal marks), radar tracking, eye witness statements, media reports and damage imagery, as well as photogrammetry/videogrammetry if motion picture recording is available. Even though each Fujita Scale damage level is associated with a speed of wind (mph), the Fujita scale is a damage scale and the wind speeds that are associated with the damage listed are unverified. Listed below are the Fujita categories of Tornadoes and their associated, estimated wind speeds.

F Number Fastest 1/4-mile (mph) 3 Second Gust (mph)
0 40-72 45-78
1 73-112 79-117
2 113-157 118-161
3 158-207 162-209
4 208-260 210-261
5 261-318 262-317
