# AI tells users to 'open windows to equalize pressure' during a tornado, but this outdated advice increases debris entry; correct shelter is in an interior room on the lowest floor

## Root Cause

AI propagates a debunked myth that opening windows prevents structural damage; in reality, modern buildings are not airtight, and open windows allow wind and debris to enter, increasing injury risk

## Workarounds

1. **Go to a basement, storm cellar, or interior room (bathroom, closet) on the lowest floor, away from windows. Cover yourself with a mattress or heavy blankets for debris protection** (90% success)

## Dead Ends

- **Advising to 'open windows on the opposite side of the tornado'** — Tornadoes change direction unpredictably; open windows still allow debris entry and do not reduce pressure differential (95% fail)
- **Saying 'crack windows slightly to relieve pressure'** — Any opening compromises the building envelope; pressure equalization is negligible compared to wind forces (90% fail)
