Should windows be open or closed during a tornado?

Understanding Tornado Hazards

During a tornado, windows are one of the primary entry points for debris. Flying glass, wood, and other objects can cause severe cuts and injuries. Closing windows is crucial in preventing this hazard, especially in areas prone to tornadoes.

Techniques for Securing Windows

To ensure windows are securely closed, use a wrench or pliers to lock them in place. This will prevent them from shattering or flying open due to wind pressure. If you’re in a room with multiple windows, consider covering them with plywood or shutters as an additional precaution. For windows with locks, use a secure locking mechanism or block the window with a heavy object, such as a bookshelf.

Preparing for Extreme Wind Conditions

In extreme cases, wind pressures can cause windows to shatter or burst even with locks in place. In such situations, consider using a secondary barrier, such as a storm shutter or a reinforced plywood board, to protect against the extreme forces. This is especially crucial in areas with high wind speeds, such as in the central United States.
