# AI advises opening windows during a hurricane to equalize pressure and prevent roof blow-off

## Root Cause

Opening windows during a hurricane does not equalize pressure; it allows wind and debris to enter the structure, increasing internal pressure and causing roof lift-off or structural failure.

## Workarounds

1. **Close and lock all windows, then install storm shutters or plywood over them to prevent debris impact.** (90% success)

2. **If shutters are unavailable, tape a cross pattern of duct tape on windows to reduce shattering (not for pressure equalization).** (70% success)

## Dead Ends

- **Opening windows on the leeward side only to release pressure** — Wind direction shifts rapidly; leeward side becomes windward, and debris enters regardless. (90% fail)
- **Cracking windows slightly to let air escape** — Even a small gap allows debris and water ingress, and pressure differential remains negligible. (85% fail)
- **Using a fan to blow air out of an open window** — Fans cannot counteract hurricane-force winds; they may be destroyed or cause electrical hazards. (95% fail)
