Above-ground storm shelters offer a crucial layer of protection during severe weather events, but their safety depends heavily on several factors. While not as inherently robust as their underground counterparts, properly designed, installed, and maintained above-ground shelters can provide significant safety benefits. This guide explores the safety aspects of above-ground storm shelters, addressing common concerns and providing essential information for making an informed decision.
What Makes an Above-Ground Storm Shelter Safe?
The safety of an above-ground storm shelter hinges on several critical elements:
-
Construction Materials: High-strength steel is the most common and reliable material. Look for shelters built with thick, reinforced steel walls and a robust roof capable of withstanding significant impact and wind pressure. The anchoring system is equally crucial – it must be securely fastened to a solid foundation to prevent the shelter from being lifted or moved by strong winds.
-
Proper Installation: Professional installation is paramount. A poorly installed shelter, regardless of its quality, will offer reduced protection. The installation process should ensure the shelter is properly anchored and leveled to withstand extreme weather conditions.
-
Certification and Ratings: Look for shelters that meet or exceed FEMA guidelines and carry relevant certifications, indicating they've undergone rigorous testing to withstand specific wind speeds and debris impact. These certifications provide an independent assessment of the shelter's safety and performance.
-
Regular Maintenance: Like any safety structure, above-ground storm shelters require regular inspection and maintenance. Check for any signs of damage, corrosion, or weakening of the anchoring system. Addressing these issues promptly helps ensure the shelter remains safe and effective.
Are Above-Ground Storm Shelters Safe During Tornadoes?
Above-ground storm shelters can be safe during tornadoes, provided they meet the criteria outlined above. They are not as inherently resistant to direct tornado hits as underground shelters, as the heavier debris may impact the structure. However, a well-built and properly installed above-ground shelter will offer significant protection from flying debris and high winds, significantly increasing the chances of survival.
What About Hurricanes and High Winds?
Above-ground shelters designed to withstand high winds are a significant safety advantage during hurricanes. The robust construction and anchoring system are crucial in mitigating the risks associated with hurricane-force winds. However, the location of the shelter relative to potential flooding is also a key consideration.
How Much Protection Do Above-Ground Storm Shelters Offer?
The level of protection offered varies depending on the shelter's design, construction, installation, and the severity of the storm. High-quality, properly installed shelters offer significantly increased protection compared to being in an unprotected structure. Remember that even the best storm shelter might not completely protect against the most extreme events, but it drastically improves the odds of survival.
Are Above-Ground Storm Shelters Cheaper Than Underground Shelters?
Generally, yes. Above-ground storm shelters are typically less expensive than underground shelters, primarily due to the reduced complexity and labor involved in their installation. However, the price still varies significantly depending on size, features, and materials.
What are the Disadvantages of Above-Ground Shelters?
While offering a cost-effective solution, above-ground shelters have some disadvantages:
- Potential for more damage: They are more susceptible to damage from high winds and debris compared to underground shelters.
- Less protection from flooding: If flooding occurs, an above-ground shelter might be affected.
- Visibility: Their visibility may pose a security concern.
Conclusion:
Above-ground storm shelters can be safe and offer considerable protection during severe weather when built to high standards and installed correctly. By understanding the critical factors contributing to their safety, choosing a reputable manufacturer, and ensuring proper installation and maintenance, you can significantly improve your family's safety during severe weather events. Remember to consult local building codes and regulations before purchasing and installing any storm shelter.
