If you hear sirens

It could be only a test. See schedule below.

Emergency supplies checklist

  • First-aid kit
  • Toolbox
  • Candles and matches
  • Potassium iodide tablets
  • Portable radio, flashlight, extra batteries

If you are advised to take shelter indoors

  • Go indoors and stay there.
  • Close all doors and windows.
  • Shut off all systems that draw outside air into the house such as furnaces, air conditioners, fireplace vents and dampers.
  • Stay tuned to your local EAS radio or television station. Emergency officials will be providing information and instructions over these stations.
  • The primary and alternate EAS stations for the area are WUSY-FM (100.7), WIVK- FM (107.7), and WNOX-AM (990).
  • If you must go outside, protect your breathing. Place a damp cloth or towel over your nose and mouth.
  • If you are told that it is safe to go outside, try to check on your neighbors. They may not have heard the announcements.
  • Do not use the phone unless you have a special emergency and need help. Leave the lines open for official business.

If you are asked to leave (evacuate) the area

  • Stay calm and do not rush. Evacuation can work properly and reduce your risk only if you act safely and calmly.
  • Take a few items with you. Gather personal items you or your family might need, using the checklist at right.
  • Turn off lights, appliances and water.
  • As you leave, lock your house and tie a white cloth or white towel on your front door. This sign will let emergency workers know that everyone in your home has left the area.
  • Please leave your pets at home with plenty of food and water. Pets will NOT be allowed in the public shelters.
  • Use your own transportation or, if possible, make arrangements to ride with a neighbor. Keep car windows and air vents closed and listen to an EAS radio station.
  • Find the sector in which you live and the evacuation route you should follow.
  • Follow the evacuation routes shown on the map. If you need a place to stay, shelter information points will be located along the controlled evacuation routes.

While you are away

  • Local police officers will secure the evacuated areas to protect homes and businesses.
  • ONLY authorized persons will be allowed into the evacuated areas.
  • Officials of the Tennessee Department of Radiological Health will monitor affected

For farmers and home gardeners

Your crops

  • An unharvested crop is hard to protect. But normal harvesting and processing may still be possible if time permits.
  • Crops already harvested will be safer if they are stored inside.
  • You should wash and peel vegetables and fruits from your garden before use if they were not already harvested.

To protect your livestock

  • Provide as much shelter as possible. If you do not have enough space in barns or sheds, use natural shelters such as wooded lots or culverts.
  • Take care of milk animals first.
  • Provide plenty of food and water and make sure shelters are well ventilated.
  • Use stored feed when possible.





Emergency classifications

The four emergency levels are described below in order from least to most severe.

1. A Notification of Unusual Event is the least serious. The event poses no threat to you or to plant employees, but emergency officials are notified.

2. An Alert is declared when an event has occurred that could reduce the level of safety of the plant, but backup plant systems still work. No action by the public is necessary.

3. A Site-Area Emergency is declared when an event involving major problems with plant safety systems has progressed to the point that a release of some radioactivity into the air or water is possible. The sirens will be sounded. If they are, you should listen to radio and television stations for details.

4. A General Emergency is the most serious of the four classifications and is declared when an event at the plant has caused a loss of safety systems and is likely to lead to a release of radiation into the environment. People in affected areas will be advised to stay indoors or to evacuate.
