Depends On The Crisis

Shelter in Place: Purpose of sheltering in
place is to keep threatened people inside a
protective structure. Sometimes this is the only
practical protective action especially in congested
urban areas or with special populations.
Keep the public inside structures and have them
close doors, windows, ventilation systems, ect., to
make the structure air-tight as possible.
Evacuation vs. Shelter in Place
![Page 54: Office of Education · Mercury Spill Do Not’s. When A Crisis Strikes Should You Evacuate or Shelter In Place? Depends On The Crisis . Ammonia cylinder adjacent to an elementary](https://reader034.fdocuments.in/reader034/viewer/2022051920/600d65bf8e89fc1180205b73/html5/thumbnails/54.jpg)
Evacuation vs. Shelter in Place
Evacuation: Purpose of evacuation is to
remove people from threatened area of
hazard to a safe area of refuge (e.g.
evacuation shelter).
This can be logistically and operationally
difficult to execute for a large area.
Especially with a large number of kids
