Protective Actions

If there is an incident at the Palo Verde Generating Station (PVGS) that requires protective actions, instructions on what actions to take will be broadcast through the Emergency Alert System. If you hear the warning sirens:

  • Go indoors immediately.
  • Turn on your radio or television.
  • Listen for emergency 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, take immediate action, whether you are at home, work, school, or in your vehicle. Residents in the affected area should take precautions to isolate themselves from radioactive materials in the atmosphere:

  • If you are outside, go inside a building and close all doors and windows to protect yourself from outside air.
  • Keep animals (pets, horses, poultry and livestock) inside a building if possible.
  • Turn off heating, cooling or ventilation systems that draw air from outside (recirculating air systems can be used).
  • Lower thermostats on all oil and gas burning heaters to minimize the intake of outside air.
  • If you must go outside, protect yourself by putting a damp cloth or towel over your nose and mouth. Fold the cloth several times.
  • School officials are taking appropriate protective actions for school children.
  • Listen to your radio or television, or go to ein.az.gov for further instructions.
  • Additional emergency information is printed in the Palo Verde Public Safety Brochure.

Other Protective Measures

Should radioactive iodine be released into the air, Potassium Iodide (KI) tablets will be available to individuals who may have been exposed only at the Reception and Care Center. Taking KI can protect the thyroid, the only organ that absorbs radioactive iodine. KI tablets will saturate the thyroid with iodine, preventing the absorption of radioactive iodine. 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.
