- Close and lock all exterior doors.
- If you are told there is a danger of explosion, close the window shades, blinds or curtains.
- Turn off all fans, heating and air conditioning systems.
- Close the fireplace damper.
- Get your family disaster supply kit and make sure the radio is working.
- Go to an interior room without windows that's above ground level. In the case of a chemical threat, an above ground location is preferable because some chemicals are heavier than air, and may seep into basements even if the windows are closed.
- Take pets with you and be sure to bring additional food and water for them.
- Have a hard wired phone with you. Call your emergency contact and have the phone available if you need to report a life-threatening condition. Cellular phones may be overwhelmed or damaged during an emergency.
- Use duct tape and plastic sheeting (heavier than food wrap) to seal all cracks around the door and any vents into the room.
- Keep listening to your radio or TV until you are told all is safe or you are told to evacuate. Local officials may call for evacuation in specific areas at greatest risk in your community.
