It is more dangerous to be outside in some types of emergencies. In these emergencies, the best, safest response is to "shelter in place." This means staying inside a safe building—your house, workplace, school, or other building—or entering a nearby building and seeking cover.
If you are asked to shelter in place:
- Shelter in a room with the fewest doors and/or windows possible. Ideally choose a room that has just one door and at least 10 square feet per person.
- Seal doors, windows and fireplaces.
- If the emergency is airborne (such as a disease, chemical release, or radiation) turn off ventilation and hot air heating systems (radiator heat may remain on).
- Keep at least one phone line open for emergency calls.
- Stay tuned to your radio or television, or scan official web sites for information and updates.
- Use your Emergency Go Kit.
