Protective Actions

A protective Action is any action taken to protect the public's health in response to an emergency. If there is an incident at the Palo Verde Generating Station, instructions on what actions to take will be broadcast by through the Emergency Alert System. If you hear the warning sirens, go indoors immediately. Turn on your radio or television and listen for these instructions. Officials may advise people living or working in the 10-mile Emergency Planning Zone (PDF) to take shelter or evacuate the area.
  1. Shelter
  2. Evacuation
If you are asked to shelter-in-place, stay inside your home, car or business to protect yourself from outside air and take the following steps:
  • Stay calm
  • If you are outside, go inside a building and close all doors and windows to protect yourself from outside air.
  • Lower the thermostats on all oil or gas-burning heaters to minimize the intake of outside air.
  • Keep pets inside.
  • If you must go outside, protect yourself by putting a damp cloth or towel over your nose and mouth. Fold the cloth several times.
  • Do not use the phone unless you have a personal emergency. Phone lines must be kept open for emergency calls.
  • Listen to your radio or television for instructions.

Other Protective Measures


Should radioactive iodine be released into the air during a serious emergency, Potassium Iodide (KI) tablets will be made available at the Reception and Care Center for those individuals who may have been exposed and would benefit from a dose of Potassium Iodide. While evacuation is the preferred method to avoid exposure to this element, taking KI can protect the thyroid, the only organ that absorbs radioactive iodine. KI tablets will saturate the thyroid with normal iodine, preventing the absorption of radioactive iodine gas. KI tablets have a high percentage of effectiveness for several hours after an individual is exposed. The use of KI does not provide protection against other radioactive materials or external radiation.
