Reasons why an Incident Commander might choose to Shelter-in-Place

The special needs of these populations require specific accommodations. Although they should know exactly how to provide for the special needs of their clients, and are in some cases required by law to do so, facilities that house these populations are sometimes not well-prepared to deliver the specific care that their clients would need.

In a large-scale evacuation, all resources available will be needed to evacuate the general public. This large volume of people requiring transportation will overwhelm buses and other means of transportation.

Facilities that house minors have a specific need because they are required to retain custody of the minors in their care until released in to the custody of their parents or legal guardians.

Office buildings and high-rise residential buildings generally have lower air exchange rates than single-story residential construction. This means that these large-population structures are better suited for sheltering in place.
