Why might a tornado drill at school contribute to saving human lives?

People who are prepared for a tornado and know what to do are more likely to survive. Practicing tornado drills prepared people and helps tech them what to do in the event of a tornado. Tornadoes have killed people in schools, but fatalities can be averted if people follow the right procedures.

A great example of this happened in Henryville, Indiana on March 2, 2012 when the school was struck by an EF4 tornado as students were leaving for home. While much of the school was destroyed and people were killed elsewhere, not a single death or injury occurred at the school thanks to well planned actions by the school staff.
