Quick Answer
To strengthen a DIY tornado shelter, consider using materials like reinforced steel mesh, thick steel plates, and concrete. Plywood and oriented strand board (OSB) can also provide added protection when properly secured. Reinforced doors and frames are crucial for overall shelter integrity.
Selecting Durable Materials
When building a DIY tornado shelter, it’s essential to choose materials that can withstand extreme winds and debris impact. Reinforced steel mesh, typically 1/4 inch thick, provides excellent protection against flying particles and can be used for the shelter’s walls and roof. Steel plates, at least 1/2 inch thick, should cover the doors and any vulnerable areas to prevent penetration. The roof should be at least 2 inches thick to prevent collapse.
Proper Shelter Design and Construction
A well-designed shelter should have a robust frame, typically made from steel or reinforced wood, to support the weight of the roofing material and withstand external forces. The shelter should be buried at least 6 feet underground to minimize damage from flying debris. A minimum of 10 inches of compacted soil or concrete should surround the shelter to provide additional protection. Ensure proper ventilation to prevent carbon monoxide buildup and heat exhaustion.
Additional Safety Measures
When building a shelter for a mobile home or outdoor area, consider the terrain and potential wind direction. If possible, bury the shelter at a 45-degree angle to reduce the risk of collapse. Ensure the shelter has a secure entrance and exit system, and consider installing a backup power source, such as a battery-powered siren, to alert occupants of an impending tornado. After the storm, be cautious when exiting the shelter and assess any potential hazards, such as downed power lines or structural damage.
