Above-ground storm shelters offer a compelling alternative to their in-ground counterparts, particularly for homeowners facing space or budgetary constraints. However, the question of their safety remains paramount. This comprehensive guide delves into the safety aspects of above-ground storm shelters, addressing common concerns and providing valuable insights to help you make an informed decision.
What Makes an Above-Ground Storm Shelter Safe?
The safety of an above-ground storm shelter hinges on several key factors:
-
Construction Materials: High-quality, reinforced steel is crucial. Look for shelters built with thick, heavy-gauge steel plates and robust welding. The structural integrity of the shelter directly correlates with its ability to withstand high winds and debris impact during a tornado or severe storm.
-
Anchoring System: A secure anchoring system is non-negotiable. Above-ground shelters need to be properly bolted or anchored to a solid foundation, such as a concrete slab, to prevent them from being lifted or moved by strong winds. The anchoring system should be professionally installed and inspected regularly.
-
Impact Resistance: The shelter's ability to resist impact from flying debris is vital. Consider shelters with features like reinforced walls, impact-resistant windows (if any), and a strong roof designed to withstand significant pressure.
-
Certification and Testing: Look for shelters that meet or exceed FEMA guidelines and have undergone rigorous testing to prove their ability to withstand extreme weather conditions. Certification from reputable organizations adds a crucial layer of assurance.
-
Proper Installation: Professional installation is key. A poorly installed shelter, even one made of superior materials, is compromised and may not offer adequate protection. Ensure the installation process adheres strictly to the manufacturer's recommendations.
Are Above-Ground Storm Shelters as Safe as In-Ground Shelters?
While in-ground shelters generally offer superior protection due to their buried nature, well-built and properly installed above-ground shelters can provide a significant level of safety. The crucial difference lies in the level of protection against direct impact from extremely large projectiles. An in-ground shelter is inherently less likely to be hit by large debris. However, above-ground shelters, when built to high standards and correctly anchored, can withstand the majority of storm debris and high winds, offering excellent protection in most situations.
What are the Common Safety Concerns with Above-Ground Shelters?
Some common concerns regarding above-ground storm shelters include:
-
Wind uplift: Improper anchoring is the leading cause of shelter failure. A poorly anchored shelter can be lifted or even blown away during a severe storm.
-
Debris Impact: While strong materials can mitigate the risk, large debris can still cause damage to a shelter, particularly if it is not properly reinforced.
-
Flooding: If the shelter is located in a flood-prone area, proper drainage and elevation are crucial to prevent water ingress.
How Can I Increase the Safety of My Above-Ground Storm Shelter?
To maximize the safety of your above-ground storm shelter:
-
Choose a reputable manufacturer: Research thoroughly and select a company with a proven track record of producing high-quality, durable shelters.
-
Ensure proper installation: Professional installation by a qualified contractor is essential.
-
Regularly inspect your shelter: Check the anchoring system, walls, roof, and doors for any signs of damage or deterioration.
-
Develop a family emergency plan: Plan evacuation routes, communication strategies, and other essential steps in case of a severe storm.
What are the differences in cost between above and below ground shelters?
The cost difference can be significant. Above-ground shelters are generally cheaper to install due to less excavation and labor required. However, the price will vary widely depending on size, features, and materials. It is always best to get several quotes from reputable vendors.
What are the space requirements for an above ground storm shelter?
Above-ground shelters require less space than in-ground shelters, as they are installed above ground. However, you still need to factor in sufficient space around the shelter for access and proper anchoring. The exact amount of space will depend on the specific shelter model.
In conclusion, above-ground storm shelters can be a safe and effective option for protecting your family during severe weather, provided they are built to high standards, properly installed, and regularly maintained. Thorough research, careful selection, and adherence to safety guidelines are essential for ensuring optimal protection.
