Nuclear Emergency Preparedness Sheltering in Place What To Do When Taking Shelter. In-house shelter may be recommended during a nuclear power station accident. In-house shelter means going indoors and remaining indoors until the emergency is over. Such action will reduce an individual’s exposure to radiation resulting from a radioactive release of short duration. When instructed by local and state emergency officials to take shelter:  If you have livestock, put them under cover and provide them with stored feed and water. Go indoors and close all windows and doors. Turn off fans and heating and air conditioning that require outside air, and close any air intakes. Do not use your telephone unless it is absolutely necessary. Keep phone lines open for emergency communication. Cover all open food containers. The food, water and milk supplies in your home are safe for consumption. Do not eat any produce from a vegetable garden until you are advised. In the event of a radioactive release, the produce may become contaminated. Remain indoors until officially notified that the emergency is over. Remember to stay tuned to your local EAS radio or television stations for emergency information.         Notifications Sirens Sheltering in Place Classifications Evacuations Sectors EAS {Public Safety Home     Back to Public Safety Home
