TERMINOLOGY:
Evacuations: "Evacuations" may be campus or building specific, depending on the nature of the incident. The main priority is to safely and expeditiously move all people within a building or area to a safe location.
Shelter-in-Place: "Shelter-in-Place" procedures will occur when evacuations would pose a threat to safety, but would not require a lockdown due to the type of threat. Typically, "shelter-in-place" procedures will be initiated with notice of tornado warnings, bomb threats, and hazmat incidents.
Lockdown: "Lockdown" usually occurs during situations where imminent threats to life safety are present, and when the option to evacuate is not feasible or would pose a greater threat to life than locking-down. An example would be an active shooter incident. The main priority is to contain people in a secure area, ensuring that all windows and doors are locked. Once the incident is stabilized and the area is secure, evacuation procedures may take place.
