Topic Overview

In many types of public health emergencies, the safest thing to do is
simply to stay indoors. If the air is unsafe because of an incident involving
hazardous chemicals, radiation, or an aerosol release of a biological agent,
local authorities may advise you to “shelter in place,” which limits your
exposure to the outside air.

To shelter in place:

  1. Make sure all family members and pets that are
    at home are inside. Then close and lock all doors and windows.
  2. Turn
    off air conditioners, air exchangers, fans, and furnaces. Close vents and
    fireplace dampers.
  3. Move to an inner room, preferably at or above
    ground level and without windows. (If the incident involves radiation,
    authorities may tell you to take shelter in a basement.) If you have an
    emergency supplies kit, take it with you. At the very least, make sure that you
    have a battery-powered radio and flashlight and plenty of drinking water. You can also use a radio or flashlight that is powered by a hand crank and so does not need batteries.
  4. If
    local authorities advise you to do so, use duct tape to secure plastic sheeting
    around door and window frames.
  5. Stay tuned in to the local news,
    and stay inside until local authorities say that it is safe to come out.
