It is important to remember that you may not always need to evacuate during a major emergency or terrorist attack, as leaving the building may put you at greater risk. In these situations, you should shelter-in-place.
What is Shelter-in-Place?
Shelter-in-place means to stay indoors, whether in your home, school, business or public buildings.
It may also include additional precautions such as turning off fans, air conditioning and forced air heating systems during a contamination emergency. While this may make the facility slightly uncomfortable, it will not become a life-threatening situation. This action could significantly reduce the possibility of contamination of the air inside.
When Should I Shelter-In-Place?
Shelter-in-place may be used or recommended when there is little time to react to an incident, and it would be more dangerous to be outside trying to evacuate than it would be to stay where you are, such as severe storms or tornadoes, civil unrest, or extreme temperatures.
This method may also be recommended in the event of a chemical or biological release, whether accidental or intentional. Most chemical or biological agents, if released into the air, will dissipate in a short period of time. In most cases, sheltering-in-place will not continue for more than a few hours.
If you are told to shelter-in-place at home, take your children and pets indoors immediately.
During an emergency, try to stay calm, and immediately follow the protective measures recommended by your local officials and emergency managers. You will be told when it is safe to return to discontinue shelter-in-place.
