One of the instructions you may be given in an emergency where
hazardous materials may have been released into the atmosphere is to
shelter-in-place. This is a precaution aimed to keep you safe while
remaining indoors. (This is not the same thing as going to a shelter in
case of a storm.) Shelter-in-place means selecting a small, interior
room if possible, with no or few windows, and taking refuge there. It
does not mean sealing off your entire building. If you are told to
shelter-in-place, follow the instructions provided.
Chemical, biological, or radiological contaminants may be released
accidentally or intentionally into the environment. Should this occur,
information will be provided by University authorities on television,
radio stations, and through Emergency Notification Systems.
