Official Iranian television and Iranian news agencies are broadcasting a video warning citizens in case of a nuclear strike, along with several instructions for dealing with a nuclear explosion:

 Do not look at the intense light of the explosion.

 If you are outdoors and unable to immediately enter a building, take cover behind a barrier, lie down on the ground, and cover your head and face.

 After the blast wave passes, enter the nearest building; do not stay to watch or take photos, and do not take shelter inside a car.

 Inside the building, go to the basement or the center, away from windows and exterior walls.

 Close doors and windows, and turn off the air conditioner or any ventilation that draws air from outside.

 If exposed to the outdoor environment, remove outer clothing without shaking it off, place it in a sealed bag away from people, but do not go out to throw it away.

 Wash with lukewarm water and soap, and use regular shampoo without conditioner; if showering is not possible, clean the face, hands, and exposed skin with water or wet wipes.

 Use bottled water and packaged food, and prepare to stay in the shelter for at least 24 hours.

 Do not assume the environment is safe after 24 hours; follow official announcements and emergency statements for the safe exit route.

 If a fire breaks out in the building or its collapse is feared, move to a safer shelter.

 Review these instructions with your family in advance to minimize damage.
