Should I consider my home's geographic location when building a tornado?

Tornado Risk Zones and Shelter Design

When building a tornado shelter, it’s essential to consider your home’s location in relation to tornado risk zones. The Enhanced Fujita Scale categorizes tornadoes into five levels of severity, with EF5 being the most destructive. If you live in a zone prone to EF3 or EF4 tornadoes, your shelter should be designed to withstand winds of at least 200-250 mph. A well-designed shelter can be the difference between life and death.

Site Selection for Tornado Shelters

When selecting a site for your tornado shelter, consider the following factors:

• Avoid areas near power lines, gas lines, and other potential hazards
• Choose a location with a solid foundation, such as a basement or a slab-on-grade foundation
• Ensure the shelter is at least 10 feet away from any exterior walls or windows
• Consider the slope of the land and the potential for water accumulation

Shelter Construction and Materials

A properly constructed tornado shelter can provide a safe haven during a tornado. The shelter should be built with reinforced materials, such as:

• 2x6 lumber for the walls and roof
• 1/4 inch steel plate for the door and any other potential entry points
• A minimum of 8 inches of reinforced concrete slab for the floor
• Waterproofing materials to prevent water accumulation
• A secure door with a self-closing mechanism to prevent debris from entering

By considering your home’s geographic location and incorporating these design and construction principles, you can create a safe and effective tornado shelter.
