3. Opening Windows During a Tornado Helps Equalize Pressure
A long-standing misconception holds that opening windows during a tornado can assist balance the pressure between the inside of a building and the low-pressure area of the tornado, therefore perhaps keeping the building from exploding. Strongly discouraging this practice, meteorologists and structural engineers emphasise that it is not only useless but possibly dangerous.
This myth’s foundation is a misinterpretation of how tornadoes interact with buildings. Although tornadoes produce pockets of low pressure, the pressure differential is not strong enough to cause a building to explode. The great winds and flying debris connected with tornadoes represent the actual risk.
Opening windows during a tornado does in fact raise your risk of damage and harm. It lets trash and wind inside the structure, thereby perhaps generating greater structural damage and dangerous living conditions. Besides, the time spent opening windows could be better used looking for suitable cover.
During a tornado warning, meteorologists stress that the best line of action is to seek cover right away in an inside room on the lowest floor of a strong building or a basement or storm cellar. While trying to equalise air pressure has no scientific basis for safeguarding a structure during a tornado, personal safety and appropriate sheltering procedures are significantly more vital.
