Should You Open Your Windows During A Tornado __exclusive__ -
In fact, opening your windows is likely to make the damage worse , not better. Once a window is opened, the tornado’s powerful winds can rush directly into the home. This internal wind load presses upward on the roof and outward on the walls from the inside, greatly increasing the chance that the roof will be lifted off or the walls will collapse outward. A closed house with intact windows presents a relatively smooth, aerodynamic surface to the wind. An open house, by contrast, acts like a sail or a scoop, catching the wind and providing more surface area for the tornado to push against. Engineers at the Wind Science and Engineering Research Center at Texas Tech University have demonstrated through debris impact testing and pressure simulations that a closed building is far more likely to remain structurally intact than one with open windows. The primary culprit for structural failure is the wind’s lateral force and the uplift on the roof, not a sudden pressure change.
To understand why the advice is wrong, we first need to understand the myth itself. The logic is based on the barometric pressure drop associated with tornadoes. Tornadoes are areas of intensely low pressure. As a tornado passes over a sealed house, the theory posits that the pressure inside the home remains high while the pressure outside drops drastically. This pressure differential creates an outward push on the walls and roof, theoretically causing the structure to "explode" outward.
Perhaps the most critical reason to ignore this myth is the time factor. should you open your windows during a tornado
No, you should open your windows during a tornado . It is a dangerous myth that opening windows equalizes air pressure to prevent a house from "exploding". In reality, doing so wastes critical time and significantly increases the risk of structural failure and injury. Why Opening Windows Is Dangerous
If you're in a tornado warning area, the best course of action is to: In fact, opening your windows is likely to
While pressure differentials do exist, structural engineers have found that they are rarely the primary cause of destruction.
It sounds logical in a physics-class sort of way. However, meteorologists, structural engineers, and emergency management agencies are unanimous in their verdict: A closed house with intact windows presents a
The idea of opening windows to save a house from exploding is an atmospheric urban legend. It fails to account for the violent mechanics of wind damage and internal pressurization. By keeping your windows closed, you maintain the structural integrity of your home's envelope for as long as possible. More importantly, by ignoring this myth, you save the only thing that truly matters in that moment: the time you need to get yourself and your family to safety.
